CPU Fan not running

How can I tell if my CPU fan is not running. I do not hear the familiar noise. Is there something I can do before I call someone to fix it. I have never opened up a computer so I am a little intimidated.

If the system is a couple of years old, the fan may be clogged with dust so the blade can't turn; these little suckers don't have much torque.
You can find the little fan pretty easy since (unless you have a high-end video or sound card) it will be the only one actually on the system board.
If you know how to access the BIOS on your particular computer, you may have one that monitors the CPU temperature and tells you in degrees.

Watch the screen at bootup for a message about entering 'Setup.'
This will give you the key to press and it often must be done very quickly; it's often F1 or F2.
Some BIOS will call the function Advanced or System something.

Don't make any changes you don't understand and when you exit, don't 'Save' any changes.

My computer was in the shop for something unrelated to this problem and now that I have it back it (the cpu fan) sounds like I'm running a vacume it's that loud.


Hi Tim,

I can not say for sure that this is whats happening, but from your description, it seems logical.

After work is done on a computer, sometimes one of the ribbon (data) or power cables isn't completely secured. It can move around within the case, especially if it is transported (like back from a shop).

On occasion one of the cables comes in contact with a CPU fan (or any of the fans in a computer).If it does, the noise they make is horrendous.

Fortunately, the fix is easy. Get a flashlight and a screwdriver.
  • Open the box.
  • Switch the computer on
  • Locate the noise source if possible paying attention to the areas around the fans.
  • When you find it switch off.
  • If it was a cable just relocate it out of the way.
If this turns out not to be the problem, please comment back with more detail.

Best regards

Mike

I have a Dell inspiron 1525...I have found that now, after a year and half the fan has become loud and noise. So noise, I wake up in the middle of the night, hearing my computer cooling b/c the fan is so...


you need to buy a new fan, your fan is about to give up the ghost. if you let the fan die while the pc is running, it might burn out the cpu.

fans are very cheap, like a few dollars, and do not always last forever.

Look underneath your Laptop, you should see some ventilators in the casing, you CPU fan will be near there. If you've got you laptop running, just feel around any of the vents, the heatsink, ducting and fan will be locate close to where you can feel warm air flow.

LOUD cooling fan noise comes and goes...usually when downloading and sometimes when just sitting unused. have cleaned it completely ...someone said possible fan drivers or heatsink (colling fins are...


Some fans are automatically temperature-controlled -- they speed up, and, of course, make more noise, as the temperature rises.

Background tasks, such as Windows Automatic Update and scheduled virus-scans, can cause the computer to become "busy" when otherwise "sitting unused".

Next time the noise increases, enter CTRL-ALT-DELETE and open "Task Manager", and click the "Performance" tab, to see if the CPU-usage is reaching 100%. Click the "Processes" tab, and then click on the 'CPU' column-heading, and click it a SECOND time, so that Windows lists the "top" consumers of CPU at the top of the list of processes. Which process is consuming the majority of the CPU?

Loud motherboard fan on Dell Dimension 9100


depends on the noise. Rattling: Ensure that all cables are out of the way and not touching the blades. Loud screaching noise: replace the fan immediately. now when you say mother board fan is it inbuilt?

Foxconn CPU fan making noise


It sounds like the fan bearing is shot, I'd recomend not using the computer until fan is replaced.
yes it is possible to replace the fan, i would recomend that you replace it with an aftermarket cooler. all you need is what kind of CPU you have, then find out what kind of socket it is, from there you can find the cooler you would like.

Cpu fan not running fast enough


This will depend on the motherboard you are using.

however, you need to make sure that the CPU fan lead is plugged into the correct plug on the motherboard... for example, I have an Intel 975xbx motherboard and it has 4 fan plugs, but only one of those is for the CPU. The others are for front/rear/top fans. If the CPU fan is plugged into one of the secondary ports, the CPU fan wont speed up correctly.

Also, some BIOS settings in the motherboard allow you to enable or disable automatic fan speed adjustment, and also set the temperature points.

Sony TZ240n problem.


If less than 90 days, it is under Sony's full coverage. Usually the fan runs intermitantly. Check that air paths are not restricted.

Fan Noise on Dell Dimension 8100


All computer fans have a general design.  The name in front of "fan" really refers to the designation.  You'll see case fan, processor fan, CPU fan, cooling fan, etc.  In the case of CPU/Processor fan, some are sold with heatsinks (the metal block sitting on top of your CPU).

The first thing you want to do is make sure the fan is clean.  Chances are dust buildup is causing the excess noise.

If that's not the case and you're looking to replace the fan, then you first need to find out the size of the fan. General sizes(diameter X width in mm) are listed on this page:

http://www.svc.com/case-fans.html

Generally, you're looking for something that will match the size of what you're replacing & push enough air at a reasonable noise level to cool the heatsink/CPU.  You want to stay in the area of 30dBA max for noise.  You also want to see if it has a 3-pin or 4-pin connection.

For example, if you have an 80mm fan, I would suggest something like this:

http://www.svc.com/saf-b82-19.html

It's pretty quiet with good airflow.  Also, it has a 3-pin connection, but includes an adapter for a 4-pin connection.

Asus fan problem


Actually this is a common problem on ASUS boards with a chipset fan. The fan begins to wear out and starts making a noise that is intermittent at times. The only real solution is to replace the fan which requires the motherboard to be taken completely out of the case. An alternate solution would be to disconnect the fan BUT you run the risk of overheating the chipset. My experience, however, is unless you are using your computer to its extremes, you won't cause any damage. Note, that is my experience and you do so at your own risk but like I've said I have never had a problem with that at all.
