DV6 laptoip fan noise solution?

I recently upgraded my DV6-6100 to Windows 8 which is not an HP supported upgrade and eliminated the HP Power Manager and switchable graphics (Now running on the Intel graphics).
After the upgrade the laptop fan would switch to high speed periodically, run for a while, then go back to normal. Task manager did not show high CPU or other activity and SpeedFan showed temp at 117F-120F whether the fan was running or not. During the high speed runs the fan noise was objectionably loud.
I first tried to fix the problem by enabling FanAlwaysOn in the BIOS in he hope of eliminating heat build up but that didn't seem to help. I then tried changing the power profile to set Max CPU at various levels less than the 100% default and settled at 95%..
The fan now runs constantly but at a very low speed and is almost inaudible. I can not tell any difference in performance but I do not have any CPU or graphics intensive apps with which to test. MS Office apps and web and DVD video seem fine.
Is this expected behavior from changing the power profile to set maxCPU less than 100%?
Any down side from having the fan always on?

I had upgraded my touchsmart to Windows 8 since it was a touch enabled notebook.
Upon completion of the upgrade, my notebook ran a little on the warm side and the fan was quite loud. I had discovered that the reason for this was that the switchable graphics system was broken by the upgrade. This resulted in both cards running simultaneously which the notebook was not designed to handle the heat generated by both cards.
I did manage to get my switchable graphics to work and the system became much cooler and quieter.
I'm not certain if this will work in your particular scenario, but this is worth trying.
Try the steps exactly as outlined in this thread. The steps do need to be followed in order as it typically fails when steps are omitted or done out of order.
The fan can fail early if it is constantly running, but let me know what happens with the steps provided.

Fan noise solution?

ive had my 12"pb for a few months now, and am very happy with it except for those noises coming from the fans in the back. even with one or two basic applications running they kick in almost immediately. i spent alot of time looking through these forums - it seems to be a problem that happens quite often, maybe with every 12"pb?
anyway, the one solution that seemed to work for some people is one that i would rather not do - replacing some kernel extension text which changes the temperature cut off on the CPU for starting the fan: (http://discussions.apple.com/thread.jspa?threadID=271910&tstart=90) ive only had bad experiences when messing around in the kernels and dont want to get burned on this one (either ways, haha).
one strange thing i noticed when using Temperox to check the temps of different parts is that my right rear fan speed stays at 37 rpm while the left rear fan is turning around 5000 - 7000 rpm pretty consistantly. could this be something serious?
or does anyone have any other solutions on this? or have many people decided to live with the constant whirring? is apple listening? could this be fixed in 10.4.7?
other posts ive found on the issue:

"ill guess ill hold out hope for this being fixed in system updates.. "
Don't count on them.
This kind of problem has been around since before Tiger came out and Apple hasn't done anything about it.
There is one other suggestion that helped me, but with a different problem.
You could save your data from your HD to another source (another computer, CD, DVD, external hard drive, ect.) and then delete everything on it with the option to set it as "zeros" and then reinstall everything again.
Its a hassle to do, but every-now-and-then its something that all PC and MAC users should do. The results are usually positive, although sometimes may have no effect at all to the specific problem.
I've found that it helps to make the computer run faster and it feels almost as if brand new. Computers after a while get filled with so much junk that after a while they tend to run either pretty slow or end up with problems you'd have to fix one by one.
The other thing to do before and after is to reset the PRAM. You can use the search option in Apple Support to find out how to do this and it'll explain as well the function of the PRAM.

Neo2 - NB Fan noise solution ?

Hi all
My first post here.
Anyone try 1.41mod BIOS and NB Fan control ?
after setup threshold on 40 C it works ) Noise is on an acceptable level.
But... it looks like the fan never speed up !!! Always low speed ?
NB temp never reaches above 40 C ?
the question is a NB has temp diode ? it should but it has ?

I don't think it has a temp diode or either it has no effect with smartfan.
I used the same bios with nb smartfan enabled and after having played hl2 for just 3 hours while the NB fan speed always stayed "low" my hdd crashed (had to reinstall).
After that i reinstalled the 1.4 bios and hooked up a Zalman fanmate. With a reduced RPM of 4000 (which seems to be a lot higher than the "low" reading) the system runs now rockstable (A64 3500+ @ 2475 MHz, 225 FSB, 4 X HTT).
Another "effect" I noticed when running with the modded BIOS was a hugely increased system temperature. With the fanmate and 4000 RPM it's lower now. Could it be that the "system temperature" diode is in fact the NB temp diode?

Re: Pavilion DV6 - loud fan noise and Core temp hits 89 degrees

My fan is beginning to be noisy, only started a week ago when it was a really hot day

What is the exact model and product number of the notebook in question?
NOTE: Do not provide the serial number.
How noisy would you describe it to be? It is normal for the fan to spin faster as time goes on due to various amounts of dust build up inside the notebook.
I recommend starting with the steps listed in this video. It covers desktops and notebooks.

Solution to ati x800 xt related fan noise

i am so happy, that i need to share this with everybody else:
a few weeks ago i decided to upgrade my gpu to tht ati x800 xt. i won't bore you with the fact, that it is a great card, fast and - truely - silent. the problem was that the due to the heat of the card the pci slot fan, just beneath the superdrive, started spinning at over 43% (i am using the hardware monitor tool for measurements http://www.bresink.com/osx/HardwareMonitor.html).
i looked everywhere for a solution to my problem, which i thought was either
a) replacing the pci slot fan
b) replacing the x800 xt fan
c) lowering the speed of the pci slot fan
d) replacing the gpu
it took me a week, until i bumped into the following page:
http://www.barefeats.com/radx800.html
if you read further down you we will notice that some of the tests were done with an overclocked ati x800 xt. greedy as i am, i forgot about the noise and decided to hunt for even more gpu speed. and there i went to http://thomas.perrier.name/software/ATIcceleratorII.html and downloaded the aticcelarator tool. and there it struck me:
as soon as i increased the speed by increasing the card's clock speed, well, the pci slot fan went to 46%. yes, you read me. if you do the exact opposite, you will lower the fan speed.
and here is the solution that works for me:
to reduce pci slot fan noise, underclock the card to
core 475 -> 445 (-5%)
memory 499 -> 472 (-5%)
and since my powermac g5 2.0 ghz has reached a pci slot fan speed of 41%. just slow enough to be under my annoyance level. you will need to play around with the parameters, since (ati clock speed =) ati heat + mac heat + ambient heat will impact the pci slot fan.
cheers

Hi Tangier,
did you install the necessary drivers? ATI DISPLAYS 4.5.7.
Works perfectly on both my G5/Dual 2.5 and G5/Dual 2.7. If it still does not work try to reinstall the latest Combo update, presently Mac OS X 10.4.8 Combo Update (PPC)

Problems with new Yoga 2 Pro (battery, fan noise, yellow, screen orientation, on-screen keyboard)

I purchased the Yoga Pro 2 on Thursday October 17. I love the computer for so many reasons, (especially since it replaces my 4 year old Compaq that was 6.5lbs!) however, I am also having a few issues with it.
It is the i7/8GB/256GB model from BestBuy. I am experiencing the same yellow issue as is mentioned by many on here. I didn't realize it, though, until reading these forums and then comparing to my old computer and my ipad and iPhone. A little disappointed, though it looks like Lenovo may be working on a solution.
But the real reason I originally came to look at this forum is because of 2 things: my fan and battery.
The fan (on the right side of the keyboard) is always on! I didn't expect this, and am wondering if mine is a lemon or if others are noticing the same thing. It's pretty noticeable, especially in a quiet room. I was showing off my new computer to a friend and the very first thing she said was that it was loud! She was using a MacBook pro, which wasn't making any noise at all.
The second thing is the battery... I am attaching 4 photos all taken within a few minutes of each other. If you cant see them, they are all of the battery meter on my screen. I am listing the time of day (to show how much time passed), percent remaining, and time remaining:
10:04 (88%) 306 hr 15 min
10:05 (88%) 8 hr 48 min
10:09 (86%) 4 hr 54 min
10:29 (81%) 5 hr 12 min
I feel like my computer just cant make up its mind!!
Another issue I had... I turned on my computer to show it to a friend (same friend who said it was noisy) and the screen image wouldn't flip when in any of the modes. This means I showed her the stand mode with an upside down image. Even in tablet mode I couldn't get it to flip. I turned the computer off and then on again, and luckily it decided to work, but it was frustrating, and I hope it's not something that becomes an issue.
Also, when I have the computer in tablet mode, the keyboard automatically pops up when I click somewhere to type... but this doesn't happen in stand mode or tent mode. Is this normal? I would have thought that the keyboard would appear in any of those modes, since the real keyboard is not accessible in any of them. And of course now that I am testing it out while writing this, none of the modes (including tablet) is having the keyboard come on screen. Of course, I know I can always choose the icon on the task bar to bring up the keyboard, but it would be nice if the computer did it automatically since it knows there is no other keyboard accessible in those modes. Is this an issue anybody else has had?
I really do enjoy using this computer, but some of these issues really need to get worked out if I am going to keep it. I'd love to hear if anyone is experiencing anything similar, and if there are any good fixes!

I just got a Lemontine Yoga 2 Pro i5/8GB/256GB from lenovo.com and the silver one from BestBuy in the same configuraiton. The silver one has no issues except for the crazy number of hours remaining on the battery which is fine, doesn't bother me. The fan noise is very quiet, and you can only hear it if you put your ear up to the vents in a quiet room.
Now the Clementine one...It was heating up pretty good. I put my ear to it on many occasions and can hear nothing at all, the fan is either missing LOL or doesn't work. I had an issue where I left the thing on for 4 hours, but sleep is configured after 5 hours. When I tried to use it, it showed me the screen brielfy, then blank. Tried hard reset, called Support, nothing. Support says its dead. Ok, an hour later, it turned on. I'm guessing it was too hot and was in some mode to protect itself, like a smartphone that is left out in the sun for some time, it won't power on till its cooled down.
I'm still in process of trying to get a hold of Lenovo to swap it, but since they no longer sell this configuration, I doubt they'll be able to get me a new one.
The silver one from BestBuy us solid though, love it, best in class in my opinion...actually got it from Future Shop sorry...from Canada, but they're essentially the same store.

HP TouchSmart 610-1280qd CTO Desktop PC Fan Noise

Hi,
Can you tell me if a loud CPU fan is normal for this computer?
The CPU fan is working very hard and the CPU and GPU are all ~38 degrees Celcius. The bios reports 1100 CPU Fan Speed and 3800 system fan speed. It sounds like my CPU fan is actually spnning faster than that.
Thanks
SOLVED: I spent some time with technical support and they had a model in the lab and confirmed that the loud fan noise is not by design. I returned my Touchsmart and received a new replacement and it is almost silent. I checked the BIOS and the fan speeds are reporting 1100 CPU Fan Speed and 2100 system fan speed with the same low temps above. I believe in my original machine they did not install fans right by swapping the plugins on the motherboard; I do not have solid evidence of this though.
I hope this help and just know that these machines should be very quiet most of the time other than some low level harddrive access noise.

Hello sal4303. I understand your screen is going blank.
Have you tried changing the settings for how long it takes your monitor to turn off? Here are the instructions.
Let me know if this has an effect on your issue.
Have a lovely afternoon!

Big fan noise problem: the rear fan won't shut off, the BIOS won't update, systemupdate locks up

I received new ThinkStaion (oh boy, lots of memory and CPU speed, yay!)
I unfortunately left the originally installed Vista OS on there. Very much regretting that as I believe it contributes to the following problems (BIOS).
So the original problem was that after just a month of using my new ThinkStation, the System Board died, and it had to be replaced. Honestly, all I did was choose the sleep or hibernate option in Vista to shut down. Afterwards,poof! didn't even get the proper Power lights on the system. I diagnosed this with the online docs and then sat for a few hours on our tech support line doing all the same things to re-diagnose it.
So after the replacement, the rear fan will not shut off. Jet engine noise all day. I went into the system settings and selected "Quiet" for the Fan settings but that did not help.
Research on this forum resulted in the possibility of a BIOS update fixing the problem. Comparison to my co-workers systems which arrived at the same time shows this BIOS is woefully out of date, so even if it does not fix the fan issue I want to update it. However, everything I've tried to do is failing for one reason or another.
(The fan issue does need resolution since in one week I will end up sharing an office (first time in many years, thanks IBM for nothing!) so since I don't want us both to have to wear noise cancelling headsets, I'd like to fix this without having to just pull the @#$@ power to the fan. Grrrr. )
I downloaded what I felt were the appropriate Lenovo apps to update both the BIOS and the serial number but none seem to work properly from the command line in Vista. One of the two (can't recall which) asks me to reboot and it never actually shuts down. Eternal "Shutting Down" message. Ga! The other throws some gosh awful

Then I decided Vista might be the problem and found sites recommending flashing the BIOS from a bootable USB. So I started down that path and after burning the wrong version, finally geting the AIK Vista tools installed and to the point of trying to make the USB bootable, it won't allow me to put the OS boot on it. Ah, for the days when a simple "sys a:" took care of that.
So, after reformatting the USB and pounding my head in the wall, keyboard, etc. I am at my wit's end. What to do. I just want the fan noise to go away.
This does seem to duplicate other forum messages but I can't get anywhere on this. Help!
Solved!
Go to Solution.

FYI to all the helpful folks here (and any looking to shut their jet engine off as well): Flashing the BIOS did the trick.
First I had to find a website with DOS OS files and put those on the USB instead of Vista. Oldie but a goodie, but at least it booted! No other versions would.
I had been intending to use the WinPhlash utility that Lenovo supplied with the BIOS update but since I was booting from DOS that was useless. However, I found a DOS version of it and used that instead. Boom baby! Flashed and rebooted.
It did take two boots to get it back to normal (first one gave very alarming messages about no operating system being found but I think it was just a remnant of the reboot that was triggered from the DOS session). A second boot returned life to normal and blissful silence from the server. And I was finally able to get the model and serial number back in there to get rid of the bootup message it throws for that too.
Ahhhhhhh.
Thanks to all for the hints - I believe I had gotten the idea of flashing the BIOS to solve this from some other thread I found here. This is a very nice forum to have bookmarked.

T530: Unbearable fan noise

Probably similar to this thread, the T530 I recently received has fan noise issues. I've invested considerable time in solving this, but found that a solution can be achieved with reasonable effort only by Lenovo:
Introduction:
Most ThinkPad models do not provide the operating system (or the user) the ability to set the fan speed directly (e.g. in rounds per minute) or in a fine-grained way (e.g. as a percentage of maximum speed). Instead, there are "fan speed levels", usually 9 levels (level 0 through level 7 as well as the level "disengaged"). For each level, a particular fan speed is defined and the Embedded Controller tries to achieve this particular fan speed by measuring the fan speed and adjusting the electrical properties of the fan (e.g. voltage or pulse length or something like this).
The fan noise problem:
Every time the internal temperature sensor reaches 50 °C or so, the fan starts with about 1900 rounds/minute and then quickly goes to about 2737 rounds/minute, where it is loud. Then it takes about 20 seconds, the temperature drops to 45 °C, then the fan is switched off. Then, after maybe other 30 seconds, the cycle repeats and the fan is switched on again, ...
There are major problems with this behaviour, because:
The fan is not running continously, but pulsating.
The fan is running at level 1 at a much higher speed than needed, creating unnecessary noise.
I have measured the individual fan speeds for individual fan speed levels:
The fan speeds at different levels are as follows:
Level 0: 0 rounds/minute
Level 1: 2737 rounds/minute
Level 2: 2944 rounds/minute
Level 3: 3033 rounds/minute
Level 4: 3074 rounds/minute
Level 5: 3597 rounds/minute
Level 6: 3773 rounds/minute
Level 7: 3773 rounds/minute
Level disengaged: 4754 rounds/minute
Solution draft:
A minimum solution to the problem above would be introducing another fan speed level between 0 rounds/minute and 2737 rounds/minute, with about 1900 rounds/minute. The reason this makes a difference is that there is a fundamental difference between laminar flow and turbulent flow, where the laminar flow makes nearly no noise and the turbulent flow makes a lot of noise. (Whether an airflow is laminar or turbulent is easiest influencable by affecting its speed.)
As you can see on the observed mapping from fan speed level to fan speed, level 6 and level 7 map to the same speed.
Thus, no particular fan speed would be lost if the mapping would be changed to the following:
Level 0: 0 rounds/minute
Level 1: 1900 rounds/minute
Level 2: 2737 rounds/minute
Level 3: 2944 rounds/minute
Level 4: 3033 rounds/minute
Level 5: 3074 rounds/minute
Level 6: 3597 rounds/minute
Level 7: 3773 rounds/minute
Level disengaged: 4754 rounds/minute
Solution implementation by user is impossible:
The problem, however, is that, while a user can decide which fan speed level should be active at a particular time, the user cannot decide which fan speed should actually be achieved for a particular level. Thus, the user can either decide to have 0 rounds/minute (which is not particularly sustainable, because the equipment becomes hotter and hotter) or to have 2737 rounds/minute (which is not particularly sustainable either, because both the user and other people arund the user's Lenovo computer are distracted from work).
The mapping from fan speed level to fan speed is actually stored in the Embedded Controller Programm ("ECP"). This Embedded Controller Programm is freely changeable or configurable by the user. Only Lenovo has the source code to this Embedded Controller Programm, and actually only Lenovo may know how to disassemble such a binary Embedded Controller Program in case the user wanted to change it. Thus, even advanced users cannot fix this problem by fixing it where it should be fixed.
It should be noted that, because fan speed is a long lasting issue at Lenovo, a third party has been even developed an after-market hardware solution: TPFC. However, this solution probably voids the warranty, and it work arounds the problem at the wrong place, and it costs time and money and effort to actually install it.
Only Lenovo can fix this problem:
How Lenovo should fix the problem
Thus, this is my call to Lenovo to fix this problem (at least for the T530 series, but probably W530, T430 are also affected). Ideally, the solution should be as follows:
Change the Embdedded Controller Program such that the mapping from fan speed level to fan speed is as follows:
Level 0: 0 rounds/minute (no noise level)
Level 1: 1500 rounds/minute (low noise level, sweet spot)
Level 2: 1700 rounds/minute (low noise level, sweet spot)
Level 3: 1900 rounds/minute (low noise level, sweet spot)
Level 4: 2100 rounds/minute (some noise level)
Level 5: 2600 rounds/minute (high noise level)
Level 6: 3100 rounds/minute (high noise level)
Level 7: 3773 rounds/minute (high noise level)
Level disengaged: 4754 rounds/minute (high noise level)
The reasons for this fan speed design are as follows:
The "sweet spot" where both the fan will run most of the time and where the user would not complain is between 1500 rounds/minute and 2100 rounds/minute. If the fan needs to be faster to keep the system cooled, then the user is likely to run the system with considerable load to CPU or GPU. In this case, there is no option to reduce the fan speed, but also in this case, the user probably accepts the fan noise for the computing power delivered.
The "sweet spot" in terms of CPU load is where the users do not accept fan noise while actually generating only minute CPU load (e.g. during web browsing or writing documents, where the CPU and the GPU is mostly idle). For many users, this is their normal working state (e.g. working in a quiet office, a very quiet library, a quiet bedroom, a quiet boardroom, ...). These scenarios are where Lenovo ThinkPads currently fail to deliver, unnecessarily
The "sweet spot" needs higher resolution (more fan levels allocated to these fan speeds), because slightly different load patterns may make it necessary to go from one level to the next higher level, but then the next level still should be bearable. Conversely, the higher levels (e.g. from 2600 rounds/minute on) do not need such a high resolution, because for most of the users, these levels will be only attained rarely anyway, and then they are accepting the noise.
Currently, there is no fan speed level at the sweet spot. With the proposed fix, there would be 3 fan speed levels at the sweet spot, with a neighbouring fan speed level (2100 rounds/minute) still being bearable when considering the performance delivered.
There is no fan speed level below 1500 rounds/minute. This is ok, because the fan is nearly inaudible at this speed anyway, and below a certain speed, there is a risk (depending on the fan) for the fan to actually not rotate at all (e.g. due to friction).
How much time and effort would Lenovo need for fixing the problem:
The Lenovo engineer responsible for the Embedded Controller Program of the T530 should need less than one day to change the source code of the Embedded Controller Program and to recompile it. The engineer may need one additional day to test this program (e.g. for different types of fans), and there may be a need for an additional day to release the update to the BIOS and ECP. All in all, Lenovo should not need more than 3 engineer-days (maybe worth 1800 USD) to fix the problem.
Why Lenovo should fix the problem:
Probably the whole current T series (T530,T520,T430,T420) as well as the current W series (W530,W520) fails the users in any of these scenarios (among others):
User working in a quiet office.
User working in a quiet library.
User working in a quiet bedroom.
User working in a quiet boardroom.
Thus, the Lenovo T series is currently not usable for many business users and almost all students. This problem should cost millions of USD of revenue, while fixing it would cost it maybe 1800 USD.
Incidental remark: Lenovo subsidiary can do better:
Lenovo has bought the majority of the Germany consumer electronics company Medion. Medion currently offers a consumer level notebook "E7222" for 499€ including German VAT. Despite of this low price, this notebook delivers very good fan control (that is: the notebook is nearly silent when the CPU is near-idle). (However, being consumer-grade, it does not offer a docking-station or a FullHD screen or WWAN.)
What will I personally do:
Some weeks ago, I had a powerful W530. I returned it due to fan noise for cash refund. Now I have the T530 (Serial number: R9RRF26) which has exactly the same problem. The deadline until I can legally request a cash refund runs until 2012-09-07. I hereby ask Lenovo:
To fix the problem and release an ECP or BIOS update until 2012-09-06 (it is doable, see above) or
if the problem cannot be fixed in this time (e.g. due to bureaucracy): provide me with a written statement (e.g. e-mail or forum post is sufficient) that my legal cash refund deadline (German law: §355 BGB) will be voluntarily extended by Lenovo (to some date Lenovo thinks it needs to fix the problem).
If none of the above happens, I will have to return the T530 as well. This is the 2nd chance Lenovo has gotten from me, there will be no 3rd chance. I would have to turn to Fujitsu (they do have business-class machines with big batteries, FullHD, WWAN) and they probably have better fan control.
Solved!
Go to Solution.

kaawee,
Thank you for the considerable thought that you put into your summation / analysis and proposal for a change.
I don't agree that you are wasting your time as we did make EC changes on the X220 and T420s to change fan behavior (along with several other systems). However, not all customers agree that the changes made the system behave the way they wanted and were completely satisfied (hence some of the dissenting opinions expressed here).
We are interested in feedback on T530, W530, T430 fan concerns and we are investigating. It is possible that a future change might be made, but I cannot say for certain that it will, nor can we commit to making this change within 4 days (2 now remaining) from your original posting.
Best regards,
Mark

Vaio E series - Cooling Fan noise

Hello, 2 weeks ago I bought Vaio E series. I was very excited that I will have Vaio laptop. It was like my dream wish. According to our standard, we are poor country and the Vaio laptops are extremely expensive. But, Vaio laptops are know for high quallity laptops and great support from Sony. So, I bought it. I am very satisfied with the quality. But I have one problem. The cooling fan is making a lot of noise even the CPU usage its 10 %. I have the latest BIOS version. So, Sony I am expecting from you to release a new BIOS update fixing this issue.. I dont want to start thinking that I pay a lot of money only for the name. With that money I could buy a more powerful machine but I put my trust in Sony. The model number is Model # SVE17122CXB. PS. Don't say that I should go to service center because they can do nothing. I am an IT student and I know how this stuff works. And I dont want the fact that the new laptop will be repaired. So the only solution is BIOS update. Sony, do not make me regret that I have chosen you before other brands.
I am expecting a positive feedback.

t0n1,
Engineering came back saying that fan speed control is not supported on the SVE17 hardware so there is no way on this model to control the fan speed manually. I apologize for suggesting this initially, at the time I did not have your exact model at my desk but instead I had a very similar one (SVE14A)
I also received two SVE17 notebooks and both have extremely quiet fan (especially if CPU usage is very low). Loud fan noise is not a characteristic of this model.
If you feel that the fan on your SVE17 is abnormally loud, then you have two options at this point:
1) You can make a audio/video recording of this fan noise and post it for me to review; after that i can try to give you more suggestions or let you know if this is in fact normal or not. At this time you do not mention that your computer is shutting off, so the unit is not overheating.
2) Or you can consider service. (I realize you initially refused service in your original post, but sometimes some new thermal sheets or re-seating of the heat-sink can address these issues.

Constant fan noise on macbook pro

Hello, my macbook pro (mid 2010 model, 13 inch, 2.4 ghz intel core duo 2 running Mountain lion) is experiencing constant fan activity at very high speed. The CPU however is only used at 9% of its capabilities top. The problem occured after a freeze in adobe Lightroom, since then, the fan noise start as soon as the computer starts (except if i press some keys before i turn it on for some reason, the noise would come back if i shut down the computer and restart it, or simply close it). I'm dully aware that it is normal that the fan is constantly working, but not usually at such high speed (top speed of the system), I checked all the major solutions offered on the net so far with no success (reset SMC, reset Pram, checked if i had some printer activity on the waiting list, checked the activity monitor for any particular demanding activity or tasks and finally i tried to run an apple harware test to see if some temperature probes are broken on the motherboard, however my computer for some reason is not taken care of...).
I also would like to mentionned that i change the original hard-drive not long ago for a hybrid harddrive (seagate momentus XT), yet the problem did not start after the change.
if you do not think of any solutions, you could maybe tell me if its problematic for my computer's fan to run at full speed..
thank you very much for any help you could provide and sorry for the eventual mistakes in english (its not my first language).

Re: Apple Hardware Test. There was no original install disk, as i downloaded mountain lion. While the connection was established to access to Apple hardware test, the test could not run on my mac, the AHT program said that my machine was not supported.
thank you for your diagnostic, it seemed to be a logical explanation, however, thanks to a monitor program i could check that my processor was running under normal temperatures (35°c to 75°c) so at least the temperature informations seems to be correctly assessed by the sensor.

My 2008 Macbook Pro makes a loud fan noise.

Hello -
I bought my 15" macbook pro back in October 2008. I was very happy with my purchase due to the machine's performance. But over the past year I have noticed an increase in the fan noise. It almost sounds like it's hitting against something at a very high speed, hense this irregular fan noise. The noise also increases drastically when I am working on Photoshop or InDesign. I also partitioned my hard-drive to hold windows so I can work on AutoCad.....noise increases also as I work on my machine.
Why is this happening? Could this loud fan noise damage any internal component to the machine? Should I bring it in to Apple immediately?
Thank you!

Some of the applications that you mention are somewhat CPU intensive which creates heat and results in fan speed increase and hence additional noise (to state the obvious). However if you are experiencing excessive noise when CPU loads are modest it could be that your fans are failing as all mechanical devices eventually will or you may have 'schmutz' inside that is the cause of the unwanted noise.
I suggest you open the MBP and see if there is any dust in the fans that may very well be affecting their performance. After 4 years, this is not an uncommon situation and it could be the solution to the problem.
If not, then you may consider getting replacements from iFixit or Powerbook Medic and replace them your self. It is not rocket science in this instance. If you suffer from chronic fingerfumbilitis, then have the Apple store do it for you.
Ciao.

Black Screen Saver & Fan Noises

My computer just yesterday started making loud fan noises. I've done some research on the computer and it seems to be quite a common problem with iMac, however, I have been unable to find solutions. It started after I watched a DVD on my computer and had to change the sleep and screen saver settings (or at least that's the trend I noticed). After the movie was over I shut down my computer and when I restarted it the next day, boom, loud fan. I was wondering if it had anything to do with the screen saver settings because that's all I could think of. Before, I had the black blank screen saver and now I can't find it on my computer. I don't want a screen saver with pictures, just the blank one--what it did before going to sleep. I've restored the energy saving settings.
Any ideas? I thought the DVD issues was related perhaps.
The fan (or what ever it is) noise is driving me crazy! As soon as the computer goes to sleep, the fan noise stops.

Yeah, I think that is this one...

Boot off your Install Disk while holding down the *d key*, (not c key), then run the extended Apple Hardware Test. Some disks require you to use the Option key at bootup to select AHT. Some models have a separate AHT CD.
Also, under the Apple icon at top left>About this Mac>More info...>Hardware>Serial-ATA, does it say "S.M.A.R.T. status: Verified"?

hi Arif664
Welcome to Lenovo Community Forums!
You may want to try a software Called speed fan, This gives control to your Fan and also shows Temperature readings.
Other Lenovo Motherboard have Restrictions for controlling the Fan. But give it a shot If it detected your fan then you're all set. adjust the Fan to your desired speed and fine tune it with the Temp that you're getting
If the Fan really get too Loud, beyond normal, I would still suggest to call Lenovo Technical Support for Assistance.
Best Regards
Solid Cruver.
