Ringing sound with fan?

Most of the time when the fan is running I get a high pitched ringing sound that is very annoying. I already have tinnitus, but this is a different sound.

This is just a guess but I can think of only two things to check.

Buzzing sound when the vent fan is turned on. Sound is high pitched, and I can't tell if it's coming from the top or bottom. Any suggestions?
I don't know if this applies in your case but I have had fans with metal blades that would resonate with a high pitched ringing sound. It may also be that a blade is slightly contacting a metalic mesh filter cartridge.

New High Pitch sound
If the sound is from the compressor, the unit is likely under warranty...generally 5 years.  If the unit is frozen up and the sound is from a fan that is hitting ice, defrost the unit completely.  Other fans in the unit could also be squealing.  You'll have to be a detective.

Whining noise from pc tower
No transistor will make such noise... The problem is not in your M/B. The problem might be due to the fan that cools your processor. So clean dust around the fan thoroughly.
