Hp dv3t 2000 overeheating/fan noise/cpu spikes

hi, i own a hp dv3t 2000 which is just about six months old. Since around a month ago I have been experiencing increasing fan noise and cpu spikes (100% cpu usage when really i'm not doing much at all)
i looked into this issue online and learned that it may be a airflow problem, so i wanted to take a look inside.
here's my frustration - i cannot take out the case because the screws are put in really tight and stripped, making it impossible to unscrew them. after 2 hours of intensive labor trying to unscrew my **bleep** laptop, i am so frustrated and angry that hp cannot bother to use a decent set of screws in their products.
i wonder if hp will take it in and have it fixed with the one year warranty on the product.

Increased fan noise, CPU temp and random fan rpm bursts when using Leopard

I have a 2.2 Ghz Macbook Pro that I purchased in August 2007. I was running OS X Tiger on my mac till about a week ago when I decided to upgrade to OS X Leopard. Ever since the install, I've been facing numerous problems and issues with the general functionality of the computer. Specifically, the biggest issue relates to increased fan noise and random bursts of increased fan rpm (as monitored using iStat). I did not have any of these issues when using OS X Tiger. Further upgrading to 10.5.1 wasn't helpful either as it did not resolve the issue.

Welcome to Apple Discussions!
It may be worth running the Apple Hardware Test, just in case you have a sensor going out or something like that. Sometimes and upgrade will cause an underlying problem to make itself known.
Did you do an Upgrade as opposed to an Archive and Install or an Erase and Install? If so, there could be some software problem associated with the issues you are having. I tried an Archive and Install, and had so many issues that I went ahead and did an Erase and Install. I've had no problems since.
Good luck!

Cpu fan noise

Hello! Today I installed windows 10, and suddenly my cpu fan is running pretty loud. I also changed my video card from a sapphire amd radeon 6950 to a gigabyte amd radeon r7-240. I installed the graphics card with windows 7 and I did not have this fan noise from my cpu fan, but when I upgraded, I check the temperatures and its running at almost 80 degrees celcius without doing absolutely anything. All my drivers are up to date. what could be the problem? thank you in advance, Edgard

Finally ready to fix my cpu fan noise - can someone PM?

So I have a 17" rev a imac (1.8 ghz) - now that my 3 year Apple Care plan is up (a new power supply, 2 new logic boards, and a new hard drive later) - I am ready to do anything to fix the model airplane fan noise/whine coming from the CPU fan. I know when the issue has at the forefront a couple of years ago, there was a housing modification that seemed to work for a lot of people, but I haven't been able to find it again. Could someone PM me with info about it if you know of it?
Thanks!

Fan noise after OSX update - Mail above 100% CPU

Hi,
I just updated to the latest 10.8.4 version and suddenly Apple Mail is running at 75% till over 100% CPU consumption making the fan running constantly. There is no active usage of Mail, no loading of heavy emails or anything. This problem with Mail never occurred before and it happened directly after the update so there might be a relation. The fan noise stops as soon as I quit Mail.
What could be the reason?
Thanks in advance,
Eric

Hey,
problem is solved: I deactivated and again activated my mail accounts by clicking the check boxes in Mail´s preferences menu. Immediately the CPU consumption fell to normal and so did the fan.
Cheers,
Eric

High Fan Noise and 100% CPU usage by Dock

My MacBook Pro 3.06 GHz Intel Core 2 Duo running 10.6.8 just started making a constant fan noise. When I checked the Activity Monitor, it shows my Doc CPU usage as 100%, and my Percent User Usage is about 52% System 2.5% and % Idle is 47%. These numbers are when there is nothing running except Activity Monitor. When I log out and log in as another user, the high fan noise stops, and the CPU usage of the Doc is <1%. I have tried restarting my computer, Rebuilt my Permissions, Emptied the Trash, and Reset the SMC (I think I did it correctly for the MBPro, but the Power Light did not change, and nothing seemed to be any different on my computer.) I think I recently did a recent Apple Update, but I don't know how long ago that was. But it was sometime in the past few days. Does anyone have any idea about what could be going on?
Thanks,
Frank

Fan Noise? Is this normal?

http://dl.dropbox.com/u/9081819/Default%20System%20Input%2020101204%201346.mp3

Whether it's normal or not depends entirely on what the computer is doing, how hot it is, and how fast the fan(s) was/were spinning when you made the recording. That sounds like normal high-speed fan operation to me, but we'd need much more information from you to make any really sound comments. Which MBP model do you have? What does iStat Pro report about your fan speed and CPU temp when the fan noise gets loud? What is your fan noise like at the default speed of 2000 RPM?

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.

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.

HT3964 How do I stop my Macbook from overheating and making a fan noise?

My Macbook Pro 17 Inch keeps overheating and making a fan noise after I use it for... say... an hour.
I use Windows on my Macbook, is this related to my problem? If not, do I need to get my fan replaced?
It gets annoying whenever I play a game, and then suddenly my Mac goes to sleep for no reason (probably due to overheating).
The fan noise is kept to a minimal when I use a web browser, or listen to music, but it goes up when I start an application.

Since overheating is something the computer tries to prevent, it will shut down if the temps get too hot, thus your experience is not overheating.
You can have a look at Activity Monitor (Menu Bar > View > Show All Processes) and then sort by CPU to see what the culprit is during downloading.
A hot Mac is not that big of a problem, the fan takes care of the heat and if you do not mind the noise, then that is it.

Mac Pro 2x2,8 Ghz - Fan Noise - Please help evaluate

Hi Guys,
Since yesterday, I'm the proud owner of a Mac Pro 2x2,8 - Really happy - really nice machine.
However I'm slightly irritated by the posts I've read all over the internet, saying that you can't hear the fans of this machine at all in idle.
As you may have guessed, my box is not silent at all - it is quite quiet compared to other noisy PCs, yes, but no match for the previous iMac 24" which it replaced. You could hardly hear the iMac versus now the Mac Pro... you notice it's there... sitting under the desk - audible.
I realize that fan noise is highly subjective, and I'm using the Mac in a completely silent environment. No AC, no nothing. I've tried the following: removing the hard drive and silencing the graphics card... Upon bootup the Mac would quickly "turbo" it's fans and then go to it's normal state. The loudest fan (which is drowning out all other noise) is the one at the bottom front (CPU?).
Looking at istat, it's in normal parameters (500rpm or so) and doesn't move up or down...
Comparing it to other devices, it would sound like a PS3 when having played 1 hour (fan speed at level 2-3) or an (quiet) xbox in idle mode (dvd not spinning). I know... geeky comparisons
Now, again - not close to my interpretations of "whisper quiet" "can't hear it at all"... "only hear it when I put my ear to the grill" "sounds like it's cooled passively"
Which makes me think that either
a) people out there are deaf /
or
b) my Mac needs a closer look by a genius
Would really appreciate your opinions.
Thanks,
Tom

hey tom,
you might have the same problem i have. I have the 2.8 octo 2008 mac pro. and it used to be whisper quiet. I was amazed. But recently as in the last few weeks the graphics card fan has become audible. I put in an e sata adapter last week and while inside the mac pro I took a look at the fan to see if it was dusty or visibly distressed. Nope. Couldn't find anything wrong with it. So now i'm just dealing with the noise. Which is too bad cause I really really really don't like fan noise. But the air conditioners on most of the time now so I really can't complain about a little fan noise compared to the ac's grumbling.
but i'd like to know if others are having this problem
thanks,

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,

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.

2 years of this fan noise....check my temperature?

so i've been battling the dreaded imac g5 (first gen) fan noise for the entire 2 years I've had the computer now. one midplane (out of 3 now? 4?) almost fixed the problem, but it had other problems. For the past year I have just let it go as it was in a room with a noisy window air conditioner and a noisy PC. Now I've moved and am back in a quiet room and the noise is unbearable.
Took it back to the apple store but they said it wasn't noisy (and it seemed less noisy there, not near as much "whine", but that could have just been all the ambient noise as well - music, crowded store, etc)
but my real question here is what temp should the imac g5 (1.8ghz) run at? at idle my CPU usually sits at about 155, under load about 165-170. this is acceptable right?
maybe its just a sign to give up on this machine and be an early adopter with the new mac pros and get to deal with whatever engineering probs are there (had the cube before this, bought right when it came out, cracked case, flaky sensor, temp problems, etc) or learn my lesson and wait another 9 months or so
I'm also having USB problems, but Apple told me they couldn't replace it (logic board) because my headphone jack is broken and that part isn't under warranty even though the USB is. sigh

Hi Eric, you might get more help posting in the G5 forum. This forum is for the iMac Intel Core Duo.

Why do I have fan noise after OS 10.7.5 update?

I used to have moaning sounds coming from my Mac Pro (Quad Core, early 2008) when I was in motion graphics programs, or in NetFlix. But ever since I updated to OS 10.7.5 3 days ago, the fan moaning is incessant. Help! I just spent $200 on an old geezer "official Mac" technician, who came to my home office and spent 2 hours doing DiskWarrior!
I am so busy right now, I can't stop to take the tower to a local authorized shop. Will the noise sink my CPU? What is causing it? Is it a glitch in OS 10.7.5? Or do I need new fan(s)?
Anyone hear complaints of sudden incessant noise other than mine?

I used the following:
Copy and past the following in terminal followed by your password when asked for:
sudo launchctl unload -w /System/Library/LaunchDaemons/com.apple.metadata.mds.plist
Note that if you've got anything listed in the Spotlight control panel in Privacy, it will be deleted.
To turn it back on (which I haven't tried yet since I don't use Spotlight):
sudo launchctl load -w /System/Library/LaunchDaemons/com.apple.metadata.mds.plist
When Spotlight is frantically reading everything and indexing it, a lot of CPU % is used, and the HD is being exercised too. That generates heat and could be the cause of the increased fan noise when your Mac Pro speeds up its fans to try to protect itself. 10.7.5 seems problematic in this respect and since your noise problem started after the 10.7.5 update, the two might be connected. Apple tends to run a Mac Pro's fans very slowly to keep the machine quiet, so any speedup would be noticeable.
