Whiney Fan

korcskru · 07-19-2006, 07:38 PM

In my headphones, and my microphone, a high-frequency ringing is heard behind all audio. I have determined it comes from my computer fan.

What can I do to minimize this noise?

i dont think this can be your computer fan, the Audio should block the noise out if it was.

ive not got any suggestions but post what sound card you have ( if you have one ) for the pros, It might help them lol.

Hi,

If you think it is a fan, the first thing to do is get a can of air, and make sure all the dust bunnies are blown out of the fans, power supply, heatsink, and the general case and motherboard. Some times fans can whine when full of dust. That would be my first suggestion without having more information. That information might include where do you think (which fan) it is coming from, why do you think it is a fan, etc. etc?

I think I know what korcskru is talking about, because I used to have the problem myself.

Check to see if the cable that runs from sound card to CD drive isn't near any fans, if you have such a cable. That would be, I think electromagnetic or electrostatic interference; I don't remember which.

I know its my fan because if I put my ear closely up to it from the outside of my PC, I can hear it. Also, I just opened up my PC, cleaned it all out, and tried to push any cables away from fans etc. Same story.

What sound card to you have? Some have internal mics. You might be able to look around the settings of your audio to see if you can disable this. Let us know your card and we can help you determine if you have one, and if so, how to disable it.

How do I find out what sound card I have? I imagine its probably some onboard thing.

This is from my dxdiag...

bump. Sorry to double-post, but I use skype for work, and all the person can hear is a high-pitched whine.

It looks like you use an onboard soundcard. You can purchase a sound card fairly cheap and disable the onboard sound. The pci sound cards are normally much better than the onboard and should not have this problem.

Actually, this is the reason why I don't have this problem- I bought a Creative SB Value for 30 bucks and it went away.
