• Satellite U500-10F - Dungeon fan turning ON and OFF all the time

  Hello world

  Just bought my u500-10F and installed Windows 7 Enterprise on this.

  Having a very weird problem, the fan keep turn on/off all the time every 10 seconds or more, even without any CPU load. Any ideas? Is there a fan control software?

  Rgds,
  Arley

  As you know that Win7 is not released and without support, there is therefore no Toshiba Software for any type of power control and the fan at the moment.

  Have you noticed the same behavior of fan preinstalled Vista operating system?

• Tecra series fan turns on and off without stopping

  Hello

  I have a Tecra A3 - 185 with processor 1.73 and 504 MB of RAM, which otherwise, I'm very happy for. The only problem (but important) is that the cooling fan constantly turns on and turns off. When the standby power system is turned on high-performance computer (when browsing, emailing or even doing nothing) active fan cooling for 25 seconds it turns off for 20 seconds, is it on again for another 25 seconds and so on.

  There is no even when he uses 0% CPU. I tried to change the power settings so the processor speed is reduced to 3-6 (whatever that means) with some success, but it's not really dealing with the problem all together.

  I had an another Toshiba before without any problems of this kind. Could someone tell me if it is supposed to be like this? (As I'm about to throw the computer out the window close-very annoying with this turn ups-thing) and if it is, give me some settings of the device which will take care of the problem of energy saving.

  Here, you posted the same.

  Uttered in another thread, it's normal behavior. The fan starts to spin when a certain temperature level has been reached and stops turning when the temperature drops.

• How to change the fan turning on and off in Tecra 8100?

  I would like to know if this is a way to tell the Bios or the utility how to set temperatures and speed to keep my cool computer of the fan.

  There are several utilities in internet for this but they do not work on Tecra 8100...

  Thank you.

  Hello

  Toshiba Power saver is preinstalled on all Toshiba units.
  This software controls the function of the cooling module and CPU usage.
  You can set the processor speed and performance of the fans.

  This request has been pre-installed on the image of Toshiba.

• Qosmio F50 - 10Z - fan cycling on and outside, even when idle

  My f50 is constantly the fan turns and turns off every couple of minutes, even when the computer is idle and does not run applications.

  SpeedFan shows that the GPU is constantly cycling between 55 and 65 degrees C even if there are no applications running (for example just after the start)-the fan kicks in at age 65, died at 55, and then slowly warms up again. The noise of the fan is noticeable (I don't think it's going full speed, however), and it is a bit abrupt and boring happen constantly and is not normal behavior. Core 1 and 2 on Speedfan are cycles between 40 and 45 C

  Outside temperature is 20 degrees, so the environment is unlikely to be a factor. I blasted air fan for dust (as much as you can because the f50 is not built to be taken by a user to the home page), but even when the fan runs at the output seems visibly warm.

  I am only drivers of toshiba running on the site (currently 7.15.11.7590)

  My main concern is that this will negatively affect the life of the fan. Am I being too picky or is there something else I could do?

  Thanks for the tips

  Hello!

  It's not easy to say what's the reason of this problem, I so a few questions:
  Did you install the laptop with the recovery disk or Microsoft?
  What operating system do you use?

  First of all, you should try to update the BIOS. You can find it on the Toshiba site:
  http://EU.computers.Toshiba-Europe.com-online decision-making supported Downloads & => Download drivers

  Also, make sure that there is enough free space a tower the specifications that the air circulation is not blocked.

  I hope I could help a bit.

  Good bye

• Equium A110 cooling fan coming ON and OFF very often

  I just bought a new Equium A110 and fan comes and goes off very often. Web, I go to a favorite in my browser, the fan lights while the page is loading and then turns off when it has been loaded and lights up also I scroll to the bottom of the page using the scroll wheel of the mouse. Is this normal?
  Is there anyway that I can reduce this fan on / off?

  Thank you

  Hello

  I assume that there is not much to do. I have new Satellite L100 and there is the same situation. In any case try to reduce the cooling method option in power management.

• CPU fan failure

  I have a Compaq SR5510F and when turn it on, the error message: don't have a CPU fan.  I took off on the side of the processor, and two fans that I see are turning very well and one that is in the box also turns fine.  Is the CPU fan, one upstairs that you can not without disassemble everything?  What should I do?  Anyone else have this problem with this model?

  There are 3 fans in the SR5510F. The PSU (Power Supply) contains an extraction fan. The system fan is also an exhaust fan. The CPU fan is mounted on top of a metal radiator. The message "CPU fan has failed" is triggered by a sensor. The cause can be a dusty fan, or obstruct the fins of the heatsink or a fan that runs too slowly to dust.

• Disabling the cpu fan on HP p6210f

  I recently installed a Cooler Master Hyper 212 plus, which uses a power connector 4-pin CPU fan. The HP p6210f has a Pegatron M2N78 - THE motherboard, which has a 3 - pin CPU fan power connector. The fan turns on fine, but then stops and I get a message before Windows 7 Professional can load the CPU fan has failed and the computer turns off.

  Everything I've read suggests that the new fan does not spin fast enough for the taste of the motherboard and that, given that the fan works properly, I can safely disable the CPU fan error in the system BIOS. Yet, I don't see an option for this disable in the BIOS. How can I turn off the error on a HP p6210f CPU fan?

  RoJCor wrote... "I would still be able to access my full BIOS."

  What you have is the complete HP BIOS. HP and many other features of locking of the OEM in the BIOS to prevent users from accidentally and unintentionally change the settings which becomes a service call. The only way to restore the features which have been locked, is to ask a hack or modification of one of the sites that do this kind of thing. Don't forget that the desired function may not be in the BIOS first, the BIOS can be difficult to hack or modify, or that you end up with a virus or other.

• Satellite A135-S4666 - cooling fan turns on and turns off every 20 seconds

  Hello

  I'm from the Argentina... I just bought a new Satellite A135-S4666 and I noticed that the cooling fan turns on and turns off every 20 seconds.
  It is a little annoying and it disctracts me of what I'm doing... is there a solution?

  Thank you very much.

  Hi Martin,

  This behavior is perfectly normal and nothing to worry about. If you find the noise irritating cooling fans you are likely to change their behavior by using the utility of Toshiba power where you should be able to set the cooling mode to run more quietly. I think trhe default is to allow the CPU to run at full speed, which will, of course, the fans turn every few seconds, but by reducing the speed of the CPU, the heat produced will be lower and therefore the fans will run less often.

  Kind regards

• 850 - 009na M1Z34EA #ABU: CPU fan for the 850-009na feel like Phoenix does not turn down after the power - on self test unless the BIOS is entered

  Hello

  I have posted responses to other posts on this topic, but thought I'd start a new thread to gather my conclusions. I'm sorry for a trial

  This PC is virtually brand new (only a few weeks now) and otherwise perform exceptionally.

  Basically, if the machine is disconnected from the power grid (i.e. the power is off at the plug or the power cord removed), when the machine is supplied then the CPU fan turns over 2000 rpm and stays there. All the other PC that I do this too, but the fan will slow down after turning upward. I know that this is done as part of the POST to check that the fan is running.

  If I go into any installation of seed, start-up or BIOS for example (i.e. by pressing ESC or F10 etc.), the fan will slow down immediately up to 700 rpm. It will stay like that until the next time the machine is started against the cold. If I shut down the PC - watch or stop - but do not cut the power supply, then the next time the machine is started, the fan is still about 700 rpm. It is not to turn up to 2 k + RPM when lit.

  As soon as I unplug, then the next time the PC boots, it will turn to the top and I have to repeat steps - off, boot, enter the BIOS, exit and continue. It is something to do with the cold start.

  Note that I don't have to do anything in the start menu - I for example go to the BIOS settings, exit without saving the changes, and the fan will still slow. It's going in the boot sector that slows down the fan.

  When the PC started out-of-the-box, I opted for the upgrade to Windows 10 during installation. I have read in various places that people had experienced after the upgrade, so I reset the machine to factory settings (Win 8.1) and have not upgraded, but the problem persisted. However convinces me that Windows 10 has been removed completely, as when I went to restore the backup image (i.e. dating back to what I had before the factory reset) there are references to 10 Windows (for example, it says 'Continue to Windows 10' as well as various food options). I do not understand UEFI so I don't know if that was involved.

  I tried to change the power plan options "Processor power management-> cooling system strategy" on the liabilities side, but no joy there.

  I think that the fan and sensors work, based on the findings below. These readings of temp and fan are taken from AIDA64

  After starting cold (current was cut, without entering the BIOS), machine runs dry without load

  

  Exactly the same thing--starting in cold, but go in the BIOS, do nothing and continue. Once again, no load

  

  This is after power off and resarting, but to let the PC network

  

  After the above, I used Prime95 to put the CPU support (use of 95-100%), and after an hour, the readings are:

  

  Note that even so, the fan was not particularly strong, but it's at 2222 rpm as in the first reading.

  If I play at 4K (the whole point of the PC ) the CPU so far got very warm, the GPU is but his fan turns up as planned.

  In conclusion, it seems that the POST has a problem because it does not slow down the fan after the test.

  I can live with let the machine always plugged into the sector (for example, most of the time) and I guess that's what most people do, but I would like to know what the problem is (for example if it's really something 10 Windows, or a bug in the BIOS/UEFI)

  Thank you very much!

  John

  Explain you a lot of people who maybe have returned their system immediately because of this? Others might judge normal sound. Not irritable average is not coming here to complain. Others might judge her so little. They simply don't like. You will never convince me that is not a BIOS problem. As the problem resolves itself when you enter manually each time. It can be reproduced every time.

• Tecra A9 - after CPU fan upgrade works constantly at full power

  Hi all

  I have 3 Tecra A9 notebook that came with a Core2Duo T7100 clocked at 1.8 Ghz with 2 MB of Cache. Updated every 3 to a T7700 clocked at 2.4 Ghz with 4 MB of Cache. According to Intel, these two processors TDP is 35W. Books don't get really hot and not hot. The CPU FAN starts right full power after the display of the BIOS with the Toshiba Logo screen. Under Bios Version 2.1 on all 3 systems, having the same behavior on all 3 systems. CPU properly recognized under Windows XP, Win7, and Win10. Is it possible to get the adjusted to normal CPU fan? The system isn t is hotter than upgrading the CPU, just for some reason any BIOS has now decided the fan must operate at full power. I even traded one of the CPU Fans with that of a Tecra A10 notebook but had the same effect as with the original fan. Having no idea what I could do. I hope for your help!

  Best regards

  I think that needs calibration to be performed to configure the table of fan speed.
  Toshiba Service Center to do this.

  The fans (CPU and case) are attached to the motherboard for this (the sensors) headers. Connect directly to the power supply (not a ' SSM') bypassed motherboard sensor circuit.

• 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.
