• Satellite A100 - the fan runs at high speed after idle standby

  Hello

  My laptop is Satellite A100-912.

  The problem is when I suspend it for more the a few minutes when the fan is running at high speed. This occurs on both Windows XP and Linux GNU. When the temperature of the two nuclei will more then 51 degrees C fan slows down and begins to work as expected. Suspended for a short time (about a minute or two) the fan speed is OK.

  I've updated to the latest version of the BIOS.

  Hello

  What version of BIOS you have installed? Has recently been the machine in for repair? A few interesting facts where I need some information to help you...
  By the way: is your machine still in warranty?

• New z500 - fan runs at high speed on startup

  Hello

  I just bought a new Ideapad, a MBYP9GE Z500, that I got no windows, when I turn on the laptop it works in the BIOS. The problem I have is that the fan starts in high speed immediately and it is very noisy at start up. Is this normal? I want to say how is possible that the fan is noisy so if I am not under what whether intensive? Maybe it's because I have not installed yet any system? Or is it my laptop malfunction?

  Thanks in advance!

  Hi neokenchi,

  Thank you for your response. Yesterday, I installed Windows 7 and the appropriate drivers, that solved the problem. The fan runs at high speed before installing a system was apparently the default heat setting, as you suggested.

  Thanks again!

• 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.

• 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.

• Fans always operate at high speed after power failure

  HP Pavilion Slimline S5780T - Windows 7 Home Premium 64-bit

  After a power failure a night or more recent, our Pavilion Slimline case fan and CPU fan have both run at high speed all the time, starting from the system. The level of noise is intolerable.

  I opened and cleaned all the dust from the inside of the case, including the removal of the heatsink from the CPU. Everything is clean.

  I ran the following HP Vision diagnostic, test the system, including fans. During the test of fan, the fans ran at 100%, then fell to the former level normal, quiet, then ramp back up to 100%. So says HP fans diagnostic tests are OK when there is always a problem. And it is possible for them to run at slow, normal speed.

  I installed the free SpeedFan utility, but there is not place to adjust the fan speed manually.

  How can I find the problem and the fans run at normal speed, as they did before the power failure? Everything that controls the speed of the CPU fan and the fan is broken.

  Thank you and best regards,

  Strange things happen when power flucuations or failures occur.  Most probably the motherboard has been damaged by the PPE and that is normally not as repairable by a DIY.  If you could find a newer BIOS, that to solve the problem.  Since there can be no more recent BIOS, try to remove the battery from the motherboard for the night and then put the file in and reset the BIOS to see if that helps the default value.  Otherwise, it might be repairable.

• 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

• Satellite A300 - fan always runs at full speed after full stop

  When I stop the Satellite A300, the fan always runs at full speed.

  Hello

  What? Cooling modules run, even in this case, the cell phone is off?
  Press the power button for at least 4 seconds, then the laptop must be turned off.
  Disconnect the power adapter and remove the battery
  Wait about an hour and reconnect the battery and AC adapter
  Then switch on the device after a certain time of use of turning the unit off and check if the cooling modules would stop too

• S50 satellite - B 15 P - Fans running at high speed and system crash

  Hello

  I have a new SATELLITE S50 - B 15, i7-5500U, 8 GB Ram, SSD etc., IV and v have some problems with it.

  for unknown reasons the CPU fan starts to operate at high speed, even if the temperature of the CPU hit is not 35%.
  It also froze about 10 times since I got it (April this year).

  The only way to make it work again would be me to hold the power button down until stop and start it back up.
  Once launched upward there is no mention of potential problems in the newspapers of events other than the forced closure.

  I just wanted to know if anyone else has experienced problems?

  Thank you

  Chris

  The only way to make it work again would be me to hold the power button down until stop and start it back up.

  Forcing order restores the fan activity and performance?
  Hmm it sounds like there must be some sort of system emits probably the bottom of some process locks the CPU and therefore increases the activity of the fan.

  You could start the the Task Manager and in the process tab, you will find all background applications that would appeal to the CPU.
  Click the CPU column to display all the processes of loading the CPU.

  However, you can also try to change the option of cooling method that is available in Windows Advanced Power options.
  Go to control panel → power options.
  Click here on the power plan that is currently in use.
  Then click on advanced power options and access the cooling method.
  Here you can change it from active to passive.

  

  In addition, you can decrease the status of CPU max at 90-05%

  

• IdeaPad Flex 2 - 14 d: constantly running at high speed of the fan: 8.1 Windows

  Hello.

  I have a Flex 2 - 14 d running Windows 8.1 Ideapad and real pilots.

  The fan runs constantly at high speed.

  So I have no complaint about overheating, but instead, I have to complain about is cold knees.

  Y at - it a possibility to adjust the fan speed?

  Best regards

  Eleichstetten

  I have Flex 2-15 and suffered from the same problem. By trial and error, I found that (although not documented) a specific version of the TPFanControl (http://www.staff.uni-marburg.de/~schmitzr/tpfc.html) does not work with my laptop. Opt for the 0.62e version. It is a cool utility, has several conditions of default security in standard BIOS procedures if something is still wrong. Temperature to the fan speed mappings are user adjustible, so you must refine your laptop (default values are designed for Edge E520, so don't not necesserily ideal).

  A HUGE relief!

• HP dx2000MT: why fan runs on high speed

  Hello, the fan in this machine works sometimes at high speed, can someone tell me why or what I can do to stop this please?

  The most common cause of a computer running at max speed fan is a processor overheating.

  This can be caused by:

  -Extended heavy load on the processor.

  -Malware can cause this.

  -If you use many programs at the same time as background tasks, who will do as well.

  -Dirty/dusty in the computer heat sinks.

  -Malfunctioning components from the motherboard.

  -Bad placement of the computer.

  -Desktop computers should be placed where they receive lots of air circulation.

  -They should also be placed away from heater vents / air conditioning floor. AC vents may be tempting to cool the machine but will cause condensation and destroy it.

  -Observe the fresh air intakes where on the computer. Generally low and/or front of the chassis. If there is a substantive contribution, move the unit out of the carpet and on a hard surface.

  -Do not keep the Tower in a small enclosed space. Computer Cabinet should never have the door closed with the runinng machine.

  -If it was a laptop, you also to maintain it on a soft surface such as beds and prefer to use it on a desk, or on the binder or other similar when surface into the fold.

  -Vista-era of HP computers are completely garbage as well. (Sorry HP, but it's true). Watch by substituting a newer computer. The new HP machines are not nearly as terrible as those made when Vista was released.

• Rear chassis fan Z400 always runs at high SPEED

  I have several Z400 workstations. One of them is much noisier than the rest: the rear system (case fan) fan is almost always running at high RPM. On the normal Z400s, the BIOS Setup. File | Speed of about 1 600 rpm of fan reports of temperatures of the system chassis. On the noisy Z400, the chassis fan speed is reported as 3752 RPM. The two Z400s run the latest version of the BIOS public, 3.57. Both have a BIOS Setup | Power | Thermal | Fan Idle Mode set to 1. Fan Idle Mode 1 to 5 on the normal Z400 cycling makes a huge difference in fan RPM. Bike 1-5 on the noisy system has hardly made a difference.

  How can I calm the chassis fan in the noisy Z400? I carefully cleaned to vacuum inside the Z400, including the withdrawal of the air cover that protects the DIMMs. If it's important, the Z400s running Windows 7 Pro with all the latest patches.

  I noticed that the BIOS Setup. File | Temperatures of the system reported a temperature of 23 C on the 0C on the noisy Z400 Z400 normal. Are there opportunities that "0C Température" means that the room temperature sensor is broken, and without knowing what the temperature, the BIOS runs the fan at full speed no matter what? If so, how would I debug/fix this?

  Thank you.

  Scott, you are quite right.

  I replaced the on/off switch and LED cable assembly, including the thermal sensor, on the noisy Z400 with a plug to a normal Z400. The noisy Z400 is now normal, with a rear chassis at about 1700 RPM fan. The BIOS reports the temperature of ambient air properly to 23 C.  'How to' instructions from HP for the replacement of the cable were good enough. Now all I have to do is to order another set of good cable.

  Scott, thank you very much, for the rapid diagnosis and useful links. This issue is RESOLVED. Thanks again.

• Satellite L10-117: the fan stops and only run at full speed

  I L10 - 117 with celeron M 370, my fan works for about 2 minutes and stop after only 2-5 minutes, it starts again at full speed. It only works at full speed (made a lot of noise) or stop, I noticed that my friends toshiba satellite fan (also celeronM) works at different speeds, such as laptops with centrino.

  There's this problem with my laptop, or maybe it's normall for celeron M370. Is there a software for satellite power with celeronM management?

  Darek

  Hi Darek

  Number of units of Toshiba have preinstalled Toshiba intelligence tool and it is possible to make different settings for the activity of the CPU and cooling method as well. Unfortunately, your device is preinstalled without this designed Toshiba utility.

  Computer Satellite phone has your friend?
  Check to see if he can change the parameters of cooling energy saving method.

• ACPI fan constantly runs at full speed on Toshiba Satellite L505

  Hello world!
  I recently bought a new laptop (Toshiba L505)... everything works fine except the fan under Linux. It works constantly to max speed and I must say it's quite annoying. I know it is better to have a fan that runs continuously rather than one that is not light up at all, but I really want it to solve...
  See https://bugs.launchpad.net/ubuntu/+source/acpi/+bug/321578 for more information on this bug...
  I think that it is related to ACPI but I tried everything almos (acpi_osi change, acpi = force and other hack kernel). But whatever the OSs I throw (except Windows 7), it is always at full speed (I tried the Chakra (Archlinux), Ubuntu, and PC - BSD). With Ubuntu, I tried the last kernel 2.6.32rc7...

  Thanks ;)

  Hi sunrider.

  to understand why your machine is constantly cooling at high speed, go deep into the linux stuff...

  * but you can try "acpi = off" * instead of 'force' to give the os the ability to manage the material at the level of the api...
  Maybe there is an updated driver/module implemented who knows your chipset...

  If you "force" the kernel to manage equipment of this 'acpi' way and no module is there to do the work... you see it is a bad thing...

  or you are a geek and program a module that manages your chipset to acpi... If yes pls share it with the community...
  of course I'm kidding, writing of modules is not for me...

• HP Compaq DC7800p Convertible: Fan never works at high speed

  Well Hello hp. My question is that I have the hp compaq dc7800p with intel q35 chipset. I also have the intel core 2 duo e6750, who comes to 66 without high-speed fan spining. I checked, the site of intel, that it is said that Tcase is 72 C I also have the problem with the chipset, there too big temperatures when you play. It goes up to 80 C. What I would do. Should I change cpu fan or don't start high speed at 70 ° C and for the chipset how cool up to at least 60 C, I have the normal aluminum without cooler chipset. I play the games are battlefield 3 and 4 and yesterday my pc freezes, and when I rebooted funs went at full speed, but nothing showed on the screen for 5 minutes, is now well, fortunately, but I all wory to much.

  Temperatures look ok so far.

  -In addition to being very energy efficient - Core2Duo processors have built-in thermal protection.

  If ever they come to high temperature, the frequency is decreased. If temperatures reach critical CPU turns off.

  Chipsets get usually a little hot under load.

  80 ° C is still about 25 degrees below criticism.

  What graphics card you have?

  As far as I know, feeding in these machines has only about 360 watts, which is not enough for some high power graphics cards. It is most likely the reason why your PC freezes. Video games cards consume not only a few watts, they also generate a huge amount of heat under load.

  Anyway, there are two things you can do:

  First, go to the HP Support and get the dc 7800 manual.

  Uninstall the CPU cooler and apply new thermal paste (don't forget to clean the old one).

  Then, increase the speed of the fan slowed down in BIOS F10 for better air circulation.
