• iMac 27 "mid-2011 - Intermittent problem with CPU fan running at full speed and sleep mode.

  Hello!

  My iMac 27 "has an intermittent problem with the CPU fan runs at full speed. Sometimes it happens at the time when I start it, sometimes only in my session, and sometimes only after a certain time. So does seem to be a problem of "heating".

  Second issue is with the mode 'sleep'. It may occur also at any time, at the start of the iMac, session, or after a certain time. But once he starts to go in mode 'sleep', when I wake up, it goes right back in mode after a few seconds and that it will continue indefinitely until I restart the computer.

  What could be?

  Please help me!

• Pavilion 7000: Computer freeze once the fan CPU runs at max speed

  Product name: Pavilion 7000

  Product model: 7 p - 1090d

  Product no.: QP177AA #UUF

  Operating system: Windows 7 Home Premium 64 - bit version.

  Computer blocks once the fan CPU runs at max speed. Initially, the computer would occationally freeze after waking up from sleep mode (CPU fan would be occaionally operate at full speed & freeze the system).  Now cannot load even in windows. It freezes at the configuration of the BIOS once the fan turns at speed computer crashes if the CPU fan run at maximum speed wherever you are!

  1. I did the cleanning & lubrication & even take the battery to reset the Bios but no success too.

  (Before I can reset the Bios it will run normally.)

  2. remove all USB devices except the mouse & keyboard

  3. detach & attach Ram memory & graphic card

  I saw a ROM_Recovery shunt on the motherboard label. Must I do? or can someone help, please?

  I sent to the center of HP service after a week, the service staff telling me that he was unable to go bad because my motherboard is the American version, which I have no idea what it means (my PC was purchased locally) but to bring him back.

  I solved my problem of tried to detach the Rams (2 actuators) & install only 1 on an another RAM slot first. This works. Then installed the second RAM on an another slot also without no problems so far.

  I have an old HP Office also having the location of the faulty RAM & also had replaced graphics card but it raise a peep sound error which easier to identify.

  I agree with you more HP, hardware problem is due to RAM or video card. Thanks anyway

  I hear fans ramping down when I do and reported by the BIOS fan status seems to support my theory that the fans really slow. Unfortunately, I do not yet have equipment controlling software installed on my PC so I don't see no confirmation of the fan speeds up when running in Windows 8. [HP has none of these tools?]

  If I stop and restart Windows 8 normally (so that it uses its startup optimizations 'fast'), then fans seem to go for the maximum RPM.

  The machine was purchase in Nov 2012: apparently not the internal dust is the problem and it would be not fixed by forcing a boot cold. I suspect that it is a software problem (I consider the offending software if it does not reset the hardware correctly at startup).

  It seems that the fans turn upward but never slow down: is it possible to fix this? I wish that the machine to shut up when it isn't loaded (without having to reboot to get it that way). Otherwise, there is no performance or stability problems (yay).

  Hello..
  This seems to be the problem with your bios on the desktop.
  Discover the same fan speed if you have only the keyboard, mouse and the power cord is connected.
  Also check out an update of the bios on the desktop.
  This would probably solve the problem.
  You have a bios update available on the HP Web site.

• HP h8-1141 fan runs at full speed all the time

  Processor and fun of rear cooling fan runs at full speed on Pavilion h8-1141

  Solution:

  I cleaned the inside of the computer and all the fans. It was very dusty.

  Then I pressed my finger on all the cards on the motherboard to make sure they don't lose. As for the fans, I took out and put them back in.

  Now it's working. The fans are back to normal.

• I have 4 GB of RAM, but when my i play any game, my CPU fan runs at high speed and my system gets shut down within minutes.

  I have 4 GB of RAM, but when my i play any game for example NFS most wanted, my CPU fan runs at high speed and my system gets shut down within minutes. Help me solve this problem

  If you overclocked?  If so, cancel that.  If the games you play are poorly written, it is not that you can do about it.  If you have not cleaned the dust and lint from your computer within a certain time, you should do that because it accumulates and causes overheating.  For desktop computers, remove the cover and carefully use compressed gas to blow off the dust, especially around the fins in the processor heat sink and air ducts.  For a laptop, I'll ring gas compressed through the ventilation openings.

  Good luck.

• [Aspire V3 - 771G] Fan runs at full speed without reason

  Hello world! I come here after some time to research how to fix this weird problem.

  The fact is: at the time I push the power button on my Acer Aspire V3 - 771 G, starts the fan rotating at high speed, making a horrible noise.

  I have this laptop for 3 years now and this problem is only 5 days ago.

  I did nothing to do except clean the fan with a compressor of air (by ventilation, without desasembling the pc).

  I've tried several things:

  -First of all, by using SpeedFan to monitor the single my laptop fan (useless because SpeedFan does not reconigze the fan)

  -Control of the overheating (at least none in the task of program manager used a lot of CPU, and all temperatures are correct, between 40 and 50 degrees idle, screenshot: http://www.noelshack.com/2016-18-1462730392-capturegbfg.png )

  -Then, after reading a few posts, remove the battery (nothing happens)

  -Then, I check the BIOS for any < fan="" setting=""> > (there's nothing like this in the BIOS Acer (the most recent version for my laptop)

  -Finally, I tried you use software such as NotebookFanControl or ACFanControl (nothing too, he just tell me that the fan is running at 164%, crazy?)

  So after all these things, I'm fed up and my laptop computer fan just keep running like a beast. It is a very big problem for me because I'm audio recording and this sound quite kidding with my voice on the record. And now, I can't change my laptop, for a few reasons.

  So I'm begging for your help, I except someone could help me with this.

• HP 8510W boot not until the cool, the fan runs at high speed

  I did a little research but didn't really much other than dust cleaning. I did this, even removed the fan and the heat sink.

  Operating system: 32-bit Win7

  Early days of cold, boots upwards, normally, the fan turns at slow speed. CPUID Hardware Monitor shows all the time in the range 30 c - 60 c. From a web browser will cause the fan to spped, finally at full throttle, CPUID HW Monitor says:

  TZ2_ up to 90 C

  TZ5_ up to 100 C

  Remote1 up to 90 C

  Other times remain in the range of 30 c - 60 c

  The task manager's performance tab shows 1%-3% CPU, 30-40% consumption of Mem.

  Close all does not help, time remain high and the fan continues to run at high speed. Reset does not succeed, it will cut down, try to restart and stop again. Finally, it will sometimes get a screen where Windows thinks it could not start and wants to fix/reinstall the files, or go back to a restore point. If to cool for 10 to 15 minutes, it will start normally with the low fan speed until something starts to run (CPUID HW Monitor and Task Manager do not cause the fan speed).

  So nobody knows what TZ2_, the TZ5_ and the Remote1 map 30 5 8510W mother? Is this a real plus temp likely situation, ot possibly a problem with bios/driver not reading sensor properly?

  Well well, so far, no response, but I seem to have solved the problem. I tried reverting heatsink composed of all chips connected to the conduct of heat with no improvement. By checking things right after a stop, I noticed that the graphics chip was too hot to the touch even with the new complex. This meant that it was not the heat pipe.

  Ordered a used one from eBay, put it in and now it's stay nice and cool, not more than 60 C.

  The part number for the heat pipe is 452227-001.

• Alienware 17 R2 (early 2015) freezes when fans went to max speed

  Shortly after startup & at random subsequently, my 17 R2 crashes when the left fan runs at maximum speed for a few seconds is then immediately freezes again when the right fan runs at maximum speed for a few seconds. Anyone know what's the deal?

  4980HQ, 16GB mem, 980 M

  Thank you all for your help. All my questions have been answered. Phone info Technical Support, video test "Cannot run" is a software problem with the test itself and will be fixed with the next update for it. The PC freeze is intentional Alienware BIOS programmers to ensure operation correct fan and only happens once per boot. My heat problem is partially due to the insufficient power of the 180 Watt power brick. The laptop was trying to squeeze more power from 180W power supply he could provide. That it caused the current limit, stop the power supply when the laptop has attracted 197 watts while playing games (by my measurement with an ammeter of work). This required that I unplug the power supply from the wall outlet to restore power. I have since received a 240-watt replacement power supply. Still, the system gets very hot but not like it was before. The power of the laptop now pull it at 227 Watts during the game. The draw excessive is a serious problem and will damage the power brick, if this happens too often, it would be in my case. It could also have negative effects on the laptop itself over time due to the hunger of power system. The battery took full charge for about 20 minutes before she reached 20% of power and strangled all for giving me the time to close everything and restart. So if anyone out there knows a power problem, you must contact the technical support and replace your power brick with a brick of 240W power 180W. My system is as follows.

• Satellite A300 - 24 X PSAGQE: fan runs at full speed

  Hello...

  I recently bought Satellite A300 - 24 X PSAGQE T and I have little problems with fan.

  The thing is, it does not work until the temperature rises to something about 75 degrees, but then continues to run at full throttle, even if the temp. decreases.

  SIW ISC: ACPI - 45, the CPU cores around 44 HARD drive is 36 and the fan always runs at full speed. Ive tried a couple of fan speed, program management, but it did not help.

  Is there something that could help me with this prob?
  Thank you for any response.

  Hello
  Try to update the BIOS of the laptop. You should be able to download this on the Toshiba site of the country in which you bought the laptop. I hope this helps.

• Fan CPU in Compaq Presario SG3450IL failure

  Hello
  
  I use a Compaq SG3450IL with Windows-7(32-bit) OS desktop pc. You need the card mother ms-7525 v1.0 is installed in it. The question is that whenever I turnon or restart my pc it displays "error: CPU fan failure, shutdown of PC will immediately in a few seconds.» PC service immediately. ». But, when I open the Cabinet cpu one comes to know that all the fans inside the CPU properly. I use to press F2 and ignore this issue. But, after a few months, pc allows to recover for several times. I had formatted my OS together for this issue, but no use. I contacted the service of hp on this issue and they suggested me to change the cpu fan. I want to know if these two problems can be solved by replacing the cpu fan with a new one. Please guide me on this issue. I'm waiting for your valuable suggestion that there expert day.

  Hello

  normally, while the CPU fan error comes, it appears on the screen with a red font and pc stops immediately.

  However, if the system fan fails, pc gives message with white font and generally wllows to start Windows after you press the F2 or F1.

  If you are facing the second situation then a way to disable the message of would be - to go BIOS by pressing Ctrl + F10 when booting. Then go to advance the menu and then scroll down to hardware monitor. and you can now turn off the system from the BIOS fan control.

  I hope this will help.

  As this post has now been locked, I have re-posted here in the hope that I can get some feedback from those initially involved. Including "dave dominey", "dave123', 'gestus', 'Nelucard' and 'emil.d '. Anyone had any further progress, or for those who contacted Toshiba, no news of a software patch or additional response?

  I received my upgrade Vista Home Premium 32 - bit DVD a few days ago, so who will try in combination with Ableton Live 6 and my Firewire and PCMCIA cards and display the results here in the next few days. I tried Win 2000, but has found the problem visible. I also seeks a solution based on Linux (open source is free what can it hurt not to try and no loss to start!) I read messages on the net about people running successfully VSTs etc. in Linux hosts. I could be wrong, but what I read Linux interacts with the hardware/BIOS and real time streaming audio in a way different from Windows. This could be a solution for the audio glitch = CPU fan, we are all suffering. I have a lot of research to do, but would consider blogging results elsewhere if people are interested.

  Here's hoping for some answers!

• Case fan runs at full speed

  I accidentally shorted the circuit case fan on my motherboard HP (explanation below), and now the fan runs at full speed all the time. Apart from the fact that it was a stupid thing to do, it will be a long term problem and should I try to reset the fan speed switch?

  (Long version) It's hot here these days and my computer fans seemed underpowered. I put a splitter at the exit of the case on the motherboard fan and added a second fan in addition to the original fan. All it worked well except the new fan seems to run pretty slow. I wanted to get a voltage reading card fan, but I accidentally hit the two sensors on my voltmeter and the computer shuts down immediately. He has started up and worked well, except that the throttle was no longer working and the fans were running at full speed. This also explains why the second fan turned slowly before when they were both being strangled.

  I guess that in the end I got my wish to have my fans running at full power, I just wanted to see if there are future problems leaving this way.

  Hello design_guy,

  You should not have problems with the fan rotating at high speed, with the exception that you can reduce the life cycle of the fan.

  You can install software on the computer that will allow you to adjust the speed of the fan to the computer which may help you extend the life of the fans and give you a bit of control over them.

  Something like SpeedFan should do the trick.

• Satellite Pro A120 - fan runs at full speed

  I've had my laptop for a few years, and for about a week now when I first turn on the fan runs at full speed. I restart the computer immediately and fun runs normally. I suspect overheating or dust problems since it works at full speed as soon as it is powered but not after a reboot. I left at full speed for a long time to see what is happening - I is not too annoying. I usually restart immediately.

  These laptops have the sensors of dew or something? I guess the House is cooler just now.
  Advice anyone?

  Ritchie.

  Hello

  I doubt the s sensor issue or something like that
  Cooling modules are controlled by the BIOS. The fan table that contains all the details about the features of the cooling module is stored in the BIOS and I recommend the default BIOS settings first

  So, start the laptop, press F2 and access the BIOS.
  Press F9 to get the BIOS default settings, and then save the changes and exit the BIOS.
  Of course, the cooling modules must be verified if the vents are not blocked
  The dust is more a cause of such symptoms
  Remove dust using a jet of compressed air can be useful in your situation

• Portege R500 - the fan runs at full speed during the recovery from sleep mode

  Hello

  The fan in my R500 works at full speed when he was in the system sleep.
  The only thing that helps is a reboot. :-/

  Is there a solution to this problem?

  Hello Allan

  I really wonder that you define this as a problem. From my point of view the problem is something else. You have a problem when you cannot boot up your laptop. You have a problem if you are unable to use certain features or if you can not open the DVD player. It is a problem.

  Back to your problem: have you tried to change the power settings, to change the method of cooling in the Toshiba power settings? Play a little with it. I optimized the use of my wholesale Satellite P200 and the fan operates at low speed. OK it is not the best example to compare the two models of laptops, but try it.
