I replaced the power supply fan, but I stil have a noise.

I replaced the power supply  and the noise stopped! However, I still hear a pulsing sound, that I'm guessing is the fan on top  of the CPU. Could you please tell me what the correct fan is, how to clean the heat fins and or how to replace the heat sink and fan?

Thanks!

@DavidDD1, welcome to the forum.

 

I suggest that you do a thorogh cleaning inside and out of the case.  You can use canned air to carefully blow the dust out of the fans and other components.  Also, using a small brush will help remove the dust from the fans.  Dust in the fans will cause many problems.  Here is a guide to help you with the cleaning.

The noise is a pitch that rises and falls rythmicly and begins when the computer is warmed up. It ends when I shut the computer off.

Thank you for the additional information, @DavidDD1.

 

The best way to identify where the sound is coming from is to open the case and try to isolate it.  Sometimes it is very difficult.  I have heard of capacitors making this sound when they were failing.

I opened the case and could not hear the noise. However, when I leave the case cover on, I hear the noise.
