Noise coming from cpu

By cjeanpurvis ·
I have a noise coming from the cpu and it is not the hard drive I believe it is the fan over the microprocessor running. (We had a problem in our building a few days ago where the heat got over 100 degrees over night and stayed that way most of theday.)Could you tell me if I need to replace the fan or the microprocessor. I have not open the cpu up yet. The computer is still working but the fan is running all the time. (I did do a scandisk on the hard drive and it showed no bad sectors.) This computer is a 166 mhz and it has about 86mb of ram memory and a 2 gb hard drive and a 6gb hard drive.

To test the CPU fan, make sure the computer is turn off, open the case, and unplug the fan. Then turn on the computer to see if the noise goes away. If the there's no more noise, then you have to replace the CPU fan. Then turn off the computer again, and unplug the both hard drives. Then turn on the computer and if the noise is still there, you have to replace the power supply. If the noise is still there, turn off the computer and plug in 1 (one) hard drive at a time, to see which is making the noise. If one of the hard drive is making the noise, either you can replace it or just leave it alone, since you ran scan disk and nothing was wrong with it.

Well you can't tell unless you open the cpu.Are you sure that the noise is not coming from the hard disks?You can confirm this by disconnecting the power supply to the hard disks and switching on the pc.If your pc is still working means you need notchange the processor.Just replace the processor cooling fan immediately or you may have to replace your processor also.Also check the fan of the smps.

The fan could just be loose. Anyway, buy a new heat sink and fan. They don't cost much!

I agree with answer number 1. You could just take te cover off, turn on the computer, and put your finger in the center of the CPU fan. Don't put your finger into the blades but usually there is a center point on the fan where you can place one finger and gently push until the fan stops rotating. If the noise stops you know where the problem exist. You can do this with a case fan also. Do not do this with a power supply fan unless it is external to the power supply. Also If you unplug the CPU fan and turn on the computer to see it it stops making noise,
DO NOT do this for more than the time it takes to turn on the computer and listen. Then turn the puter back off.

Here's a bit more info on the "CPU Fan". If you really do have a fan on the processor (the actual CPU) it might not be such a simple thing to simply swap out a busted fan (if that is the problem) for a replacement. In most cases there is some sort of thermal transfer "goop" between the baseplate/heatsink of the fan and the processor, and in some cases this "goop" is actually an adhesive.

Also, if it turns out that your problem is a bad processor fan, be VERY careful when you try to remove the existing fan and stick in the new fan. There are likely going to be clips that fit over the processor and hook on to the socket. It is far too easy to damage surroundiong components on the motherboard when you perform this little operation.

On the other hand, if you're simply referring to fans on the case, then it is a fairly trivial exercise.
