HP pavillion fan issues?

NOTE: this is the second time i've made this, it over-heated the first time I made it; reaching 90 degrees, that insane! I was only writing words!?
hi,
I have an HP pavillion dv6 laptop; and for the past month or two I have been having some major issues.
The first issue is that I seems to of got less powerfull, and not doing it's job properly because my laptop can over-heat, and power-offf for doing something as simple as basic internet browsing. This over-heating is a MAJOR problem because it happens without notice, and I can loose anything I could be doing when it over-heating, including work, or photoshop files.
The other, and more important issue (for me) is that it is CONSTANTLY whirring ridiculously loudly; to the point I cannot bring it into school because it will irritate the class. I cannot explain in these words how loud that fan is. Simply leaving it stationary on the desktop, I can hear the fan from across the hallway in the bathroom, and I can hear it faintly from down-stairs. My mic picks up this sound, so It is ruining my experiences on programs such as Skype.
Any suggestions on how to resolve this? I have already bought an external fan that goes into the USB, but even that can't control this crazy fan. This thing is probably meting my laptops insides!

You may want to repost in the Notebook forum -but here are some thoughts.
if the fan is running loud that means it is trying to run faster to cool things down.
What could be causing it to want to cool things down? Hot components.
Hot components could be caused by dust (thats always the first thing I check)
still running hot? could be the thermal paste or absense of it on the processor so it isn't transfering the heat to the heat sink...
or some other components that are not being cooled enough by the system because they are out of contact with the cooling solution.
repost to notebooks and see what they think.
good luck

    MSI GT70 2PC-1044US - HDMI / GPU / FAN issues
    I am having trouble with my HDMI port on a brand new MSI GT70 2PC-1044US . Whenever I plug my HDMI cable from my notebook to the TV, after a few minutes (5 - 20 minutes), my fan will start reving at around 5k RPMs and sounds like a jet engine. When this happens, according to MSI Dragon Gaming Center tool/monitor, the GPU temp reading hits 255 degrees Celsius, which is clearly a glitch. I used another monitor, msi afterburner, and when this HDMI problem happens, this tool reads a normal 40 degrees Celsius.
    Here are the things I have tried so far but the problem keeps reoccurring:
    1. Called MSI tech support, sent me the link to the newest BIOS and updated it
    2. Called MSI tech support again, claimed the HDMI is controlled by the intel graphic controller, and they recommended that i update intel drivers (every software tool on my notebook says it's the NVIDIA GPU that controls the HDMI port /shrug???), so i did this as well.
    3. Called MSI teck support again, they suggested I send the notebook back to MSI so they could take a look at the hardware. I did not do this because I did not trust the tech guy and did not want to wait a few weeks to get my notebook back
    4. Luckily, the store I bought my notebook at was nice enough to replace my notebook for a new one. I got home, tested it, and the same thing happened. So I think we eliminated faulty hardware.
    So now what? What else can I try?

    have you done EC reset? https://forum-en.msi.com/faq/article/how-to-reset-the-ec-embedded-controller
    can you try to plug the HDMI into your dell screen[insteal of sharp TV] to check if the same issue will hapends?
    Install latest Intel GPU drivers from: http://www.intel.com/p/en_US/support/detect/graphics
    then retest
    -Yes, I did the full EC reset. Once the EC flash was done, I removed the power cord from the back and the battery and let it sit for a few minutes before restarting.
    - My Dell monitor is old, and does not have an HDMI port, but I will try a different cable on a different TV.
    -I already have the most recent intel graphic controller drivers, this one of the things the MSI tech support guys asked me to do by phone

  • Has the T430 fan issue been fixed?

    Hello all,
    I am thinking of selling my Macbook Pro and getting a T430, but I am a little concerned with the fan issue being reported here in the forums. Has the problem been fixed in the newer models? Thanks in advance for your reply.

    I'm in the same situation, a year ago I purchased a T420 and I was very pleased as the notebook was very quietly most of the time. My notebook was stolen a week ago () and I'm looking for a replacement. As I understand not everybody is suffering this problem of whining fan,  have any idea  if this problem could be associated to only some particular models??. For example, this problem affects both the models with integrated & dedicated graphics (as far as I understand the dedicated GPU can generate lots of extra heat inside the machine that needs to be dissipated)??
    Best Regards
    Luis

  • G5 Unusual Fan Issue - Need Help

    While I have read much about the G5 fan issues, I haven't found anything that matches mine.
    This is a 1.8Ghz DP running OS 10.4.9 and it is really noisy due to the 2 drive bay fans running at top speed.
    All other fans run properly and respond to the air deflector removal (also checked using iStat Pro)
    Apple hardware diagnostics check out fine with everything passing and ambient temperature of the drive area is fine (90 or so degrees)as well.
    I understand that the drive temperature sensor controls the speed, but typically the issue has been the other way around. Would unplugging the sensor for testing hurt the logic board? Could the fan be bad? How about the FCU? the other fans seem to work as advertised.
    From the sounds of it, the Thermal calibration wouldn't be needed.
    Does have anybody any idea of how to correct this or can the FCU be reset? I did reset the PMU several times.
    Thanks

    Strangely enough, the answer to the problem was that the rpm controls in both the fan and the blower of the media bay were damaged. Power spike?
    While they are difficult to come by (they can't be purchased separately as they are part of the enclosure assembly) they are certainly cheaper than a logic board.
    Btw, if anyone else has a similar issue, the media blower is the only truly unique part. The media fan is the same as the fan in the speaker/fan assembly which can be easily found.

  • MBPr Fan issue

    Hello,
    I bought a macBook Pro Retina and have been experiencing some issues with the fan.I saw a lots of thread talking about fan issues but not sure if a solution has been found.
    Problem : I can be just browsing the web or checking emails or playing music through iTunes, and the fans will spin up to full speed for a minute or so, and then return to normal. (low CPU usage et low temperature < 40°c)
    Configuration : MBPr mid 2012 - i7 2.3ghz / 8GO Ram / 256GO SSD Samsung.
    I have run all updates available for my machine.I ve tried the smc & pram reset.
    Is there any solution ? Should I go to an apple store ?
    Thanks

    Can only help.
    You can also run an Apple Hardware test to see if ant problems are discovered.  Do not assume that a no-error result is definitive.

  • Fan issues galore

    So (i'm not sure of the name of the fan) the fan that is on the face of the tower with the internal speaker attached to it...went nuts and I could not get it to stop. I was told to change out the PRAM battery. I did that. Still an issue. I was told to do a clean install of leopard. Did it. Still didn't solve the problem. Out of frustration, I unplugged that fan from the motherboard and now my hard drive fan is going nuts. All of my temps are normal, nothing above 50 degrees F. Do I just need a new fan or is there something i'm missing?

    I was having fan speed issues and reinstalling the drivers for my graphics card (ATI x1900 and ATI Display utility) and restarting has apparently fixed it. I had noticed my OpenGL graphics weren't running properly and the 'Flurry' screen saver was choppy, as well as issues with DVD playback (error -70017). I was trying to fix those problems and it ended up solving them and the fan issue as well.
    So maybe try reinstalling your graphics drivers and rebooting. Might be worth a try. Hope this helps.

  • Unique fan issue Dv7

    Hi everyone !
    I have an old Dv7 laptop and I know its known for heating issues but im facing a unique situation. Over the years I have never have any issue , only this week I have noticed it over heats. and on further observation I can see that the fan isnt running most of the time.
    However If I tap the laptop's backside with my hand , fan just starts running as it should. I thought its some connection issue and opened it up but coulndt find anything. The fan isnt dirty aswell. Just wont run automatically....
    Also on very very rare instances It starts itself aswell. 
    Is there something I can do myself with it OR just give up and take it to a repair guy ?
    Thanks a lot !
    Regards

    Thank You for the response.  Thats the issue really , I can buy a fan and replace it myself now that I know how to get to it but How do I know its really a fan issue ?
    I mean it works normally when it finally starts , just wont trigger itself. Could be an issue with the temp sensor which senses the temperature and commands the fan to start ?
    Thanks again !
    Regards

  • More Heat/Fan Issues with Tiger--Help

    I have followed the heat & fan issues for sometime. However, I finally decided it was time to move from 10.3.9 to 10.4.3.
    I upgraded yesterday, first using the upgrade option to move from 10.3.9 to 10.4.0 and then installed the 10.4.3 combo upgrade. I've repaired permissions and rebuilt the disk directory using Disk Warrior. There were no directory errors and only a couple of trivial permissions changes.
    However, my Powerbook's fans are running constantly and my CPU heat is always pegged at about 135 degrees F, which is as hot as it ever gets. This happens within about 40 minutes of starting the Powerbook up cold and it stays that way for as long as I'm using it, regardless if there are any apps being used.
    Activity Monitor indicates that the launchd process is using from 18% to 20% of my CPU, even with nothing else running. I've disabled all Spotlight indexing and I've turned Dashboard off. It appears that it's the lanchd process that is accounting for the extra heat and fan use. It simply won't drop below the 18% to 20% of CPU. There is no other process that is using any significant amount of my CPU when nothing else is running.
    My processor is set at Automatic, the same as when I was using 10.3.9.
    I was using Silk, Application Switching Menu (ASM) and Macaroni, but I've uninstalled them. No change.
    I've reset the Power Manager (including deleting the com.Apple.PowerManagement.xml file) and reset NVRAM. Again, no change.
    Finally, when I boot back into 10.3.9 (on my backup hard drive), the fan activity and heat return to what I consider normal--much lower than with 10.4.3. Specifically, the heat and fan activity is directly related to CPU use. If I'm not doing anything, the heat drops and all the fans go off.
    There is one other curious effect of 10.4.3 vs. 10.3.9. When I'm running Firefox (latest version), all Firefox user-interface stuff (menu selections, opening many tabs in succession, etc.) are MUCH more sluggish than when using 10.3.9. Frankly, I was expecting the opposite.
    I would really like some help with this. I've read all the troubleshooing info on MacFixit and Macintouch related to heat and fan issues associated with Tiger.
    12 1.5Ghz Powerbook   Mac OS X (10.3.9)  

    I'm the originator of this thread and I appear to have an answer.
    I tried an "Archive and Install" of Tiger, on top of my existing 10.4.3 install that was giving me the trouble I described above. I had the time today and figured "what the heck[ll]".
    I then installed each additional piece (10.4.3 combo update, airport updates, quicktime updates, java updates, etc), stopping after each one to check CPU temperatures and CPU use in Activity Monitor.
    I'm now back to a full 10.4.3 install, with all current recommended Apple software and I don't have the heat/CPU use problems I previously had. There is no significant use of the CPU by the launchd process.
    I also re-enabled Spotlight indexing and that doesn't cause a problem either.
    Also, my entire system is *MUCH* quicker and responsive. I wish I knew what piece in my previous system install was causing the problem, but hopefully my experience can help someone else. When in doubt, do an "Achive and Install" rather than an update to the previous system installation.
    By the way, with heavy Spotlight indexing going on and mild web browsing, my CPU temp is just 112 to 115 degrees F. Previously, with no Spotlight indexing and with NO apps running, my CPU temp was maxed at 135 degrees with fans on full. And if you're reading this thread, you know what max fans sound like on a 12" PB.

  • Has Apple ever fixed the fan issue that results from upgrading the hard drives on 2009-2010 iMacs?

    Has Apple ever fixed the fan issue that results from upgrading the hard drives on 2009-2010 iMacs?
    My CPU fan defaults to 3000RPM.  I can rev the fan higher with 3rd party Fan controllers, but no lower than 3K.

    OR you can short out the original temp sensor, to make the fans rev at quieter speeds.
    You can also install an optical temp sensor in place of the old one, it will still read temps and adjust the fans accordingly, just not as good as an internal sensor.
    Use something like this:http://www.ebay.com/itm/New-922-9229-Cable-Temp-Sensor-Optical-iMac-27-inch-Late -2009-2010-/111106349896

  • Internal fan issues

    I have noticed that the fan in my macbook makes really loud noise when I turn the computer on, even when its really cool to touch. Also the fan is triggred on when I put it on any surface, when I am typing it turns off and as soon as I stop typing it turns back on. My apple care protection plan has expired, can someone please point out the problem and suggest what I should do to fix it.
    Thank you.

    I was able to resolve the fan issue. Just had to open the macbook and clean out the accumulated dust. Tedious work but worth it, works as good as new.
    Followed these links:

  • Yet more fan issues

    I see that fan issues are a frequent topic, but I haven't read anything quite like this so I thought I'd post just in case someone has any advice:
    About a month ago, my iMac (ALS, 1.8 GHz, 1.5 GB RAM, 10.4.4) starting turning its fan on full blast while it was asleep. They run for about 30 seconds to a minute and then turn off on their own. When I subsequently wake it up, the wake up procedure is delayed, but it appears to be okay... for a while. However, when I try to log out our shut down it will get hung up eventually requiring a hard reset.
    Notably, although most programs will work fine during the time between wake up and shut down-related crash, Toast Titanium (ver. 6) will not completely launch -- the icon will appear on the dock, but I can't access the application, and I cannot force quit it.
    This problem persisted for a few days, and then went away! Even Toast begain to work properly again. It was not clear to me what fixed it: quite a few restarts, permission repair, disk repair, etc, but nothing seemed to be a "magic bullet".
    Unfortunately, the problem just started again. That is, the fans started coming on during sleep and the computer will eventually crash. Furthermore, Toast Titanium stopped working at the same time.
    Any ideas regarding how the fan issues and Toast are connected?
    Thanks in advance!

    Check that you don't have a power supply issue:
    http://www.apple.com/support/imac/repairextensionprogram/
    And even if your serial number does not appear in the link above, run the extended hardware test with the restore disk that came with your machine. The instructions for doing so are similar that of the Powerbook restore disk here:
    http://docs.info.apple.com/article.html?artnum=86287
    If there is a power supply issue, or a fan issue that is a hardware related problem, it might appear in that test. The lack of a positive may mean something else is wrong, but at least it is a place to test. Is it happening when no third party devices or networking is hooked up?

  • GTX 970 gaming TF fan issue

    Hi,
    I have exactly the same issue like here:
    Suddenly first fan stops and the second has full speed.
    Could you recommend me what can i do? I bought this one a couple days ago.
    Thank you.

    However if the BIOS does not fix the fan issue, then you have to RMA the card, and would be best to do it with MSI as they would send you 100% working one back.

  • For anyone with newer imac fan issues.

    I posted about a week ago asking for advice on my fan issue.
    I was getting istat readings of 2500 - 3000 - 3500 (max has been 3850) rpms from nothing more than being on the internet. The computer is 2 months old and prior to having the computer worked on for an unrelated issue I had never once heard the fans kick on.
    But now my computer sounds like an airplane trying to take off - all the time.
    So, with another visit to the apple store, support-line calls and a visit to an outside apple authorized service provider - I am here to tell anyone in the same boat, that having your fans blow LOUDLY, and ALL the time is perfectly "within spec."
    I'm using it right now. Only safari is open and it sounds like monsoon season with a nice consistent rpm of 2700.
    I am certainly frustrated but did want to share this follow up with anyone that's discouraged with their fans since I know when I first ran into the issue I scoured the forums for info.
    Are they loud - you betcha!
    Are they annoying - **** right!
    Do they interfere with music and video - oh boy do they!
    Does it sound like they computer is deathly ill - absolutely!
    Is it all 'within spec' - yes, sadly it is.
    I don't see anything else I can do at this point.

    @den.thed
    I actually have that app. already. Its where Ive been getting all my crazy fan readings from.
    The temp sensors I havent paid attention to though - which are the temp. sensors and what is abnormal?
    Last time I took the computer into the mac genius(the 3rd time) - they just told me everything was fine and didnt even look at it! Then I was told by Apple Support to go to an outside service provider who also said there wasnt a problem. I had 50 screenshots of the fan at 3000+ speeds and they didnt seem concerned.
    Overall I guess what im getting at is - even if it appears that there's a problem I dont even know what I can say to these people anymore!!! No matter what I say, Im told that the computer is fine. Its by far the most frustrating product/purchase problem Ive ever dealt with.
    thanks for help so far though.
    Anyone know how much I can recoup by parting the thing out?

  • GT70 2PC Dominator Fan issue

    Well, I purchased a GT70 2PC-1631NL laptop 2 weeks ago and I'm having an fan issue. It appearently is constantly cycling on and off every 10 seconds or so, while Dragon Gaming Center reports that the Fan RPM is 0. I also noticed the Temperature of the cpu in Dragon Gaming Center to fluctuate randomly and very inconsistent between 30 and 45 Degrees Celcius.
    THis Fan spinning issue happens several seconds after starting up the laptop and even happens in the BIOS menu and it is very annoying. Updated all the drivers, reinstalled Dragon Gaming Center and ECM but nothing seemed to help.
    Anyone else experienced anything like this before?

    Didn't try that, but considering it happens when the laptop is in BIOS mode, I doubt it is software related. So I already got it packed and sending it of on an RMA to Poland tomorrow. (I'm lazy when it comes to fixing my own stuff, when it is this new :p)
    Just wondered if anyone had experienced anything like it.

  • MSI GTX 980 Gaming 4G: Fan issue, too

    I build a new system that also includes a brand new MSI GTX 980 Gaming 4G that I received today and to my considerable regret the graphics card is exhibiting fan issues similar to the ones some of you described with 970 cards.
    My MSI 980 is spinning one fan at constantly high speed from the moment the system gets turned on. It's the fan on the inner half of the card, not the one on the slot side. My card came with the notorious sticker, which I removed with utmost care. The fan on the sticker/slot side is working perfectly fine, spinning up after launch, then spinning down for as long as the card's temperature is below 60°C, then spinning up again when it's above. Regulation works flawlessly for THIS fan - it can also be controlled manually by AfterBurner, which displays the speed of this fan correctly.
    On the other hand, the inner fan does not regulate at all. It goes full throttle from the moment the system starts and never slows down again.
    _Its impossible to stop or change the speed of this second fan through AfterBurner or NVidia Inspector._
    Trying to make the other fan spin by poking it by hand, as some have described for their 970 cards doesn't change anything, either, since the other fan does run if the temperature neccessitates it.
    So it doesn't look like the behaviour of the second fan is caused by something being wrong with the hardware of the first fan.
    Anyway - at my wits' end, for now.
    My setup:
    MSI GTX 980 Gaming 4G (Bios 84.04.1f.00.f6)
    NVidia Drivers 344.60
    Monitor connected to DVI Port (through VGA adapter, for now)
    ASUS Z97-A (Bios v2012)
    Core i7-4790K
    Samsung SSD 850 Pro
    Windows 7 Pro SP1 x64
     

    I tried with the MSI Fan Control tool (v2.0.0.1) that was on the included driver CD: It also has no influence over the second fan, only over the first (properly working) one.
    I also checked my cabling and nothing seems bend or cricked. No heat-sink touching circuit boards. Guess I'll pull the plug on this one and move back to my 580 for the duration of the RMA process... I just hope the next one turns out alright.
