Buzzing

[GJSNeptune]

I opened up my case and I heard this slight buzzing, but it isn't constant. It'll buzz for a couple seconds, stop, and then do it again. It sounds like it's coming from the heatsink and/or fan. It's a Thermaltake Silent Boost. I haven't reseated it or anything yet. I wanna know if anyone's experienced it before.

A cable rubbing against a fan blade? Thats the only time Ive ever had a buzzing noise coming from my case

It probably are those coils around the CPU socket.

That was the first thing I looked for, and I still hear it when no wires were touching the heatsink or the HSF.

It probably are those coils around the CPU socket.

What coils? And what if they're causing it?


I was also thinking the sound was coming from the Abit fan just below the CPU socket. I couldn't quite tell exactly where it's coming from, but I'm almost positive it's around that area.

The coils mentioned are these. Look close, you'll find them.

But if it is the coils, is it a bad thing? What could I do to fix it?

i bet you itsw just the bearings in your fan going bad replace that instead of spending caswh to trouble shoot parts.

That's no good, 'cause I just built my computer a couple weeks ago. Bah!

 

[ocphangaz]

try to monitor the fan speed... my old PSU had a bad fan which will speed up or slow down continously which causes humms

i never knew those coils made noise, why do they make noise?

Doesn't mean the bearings are good. It could haven taken this long for them to fail enough to make noise.

Leave the side of the case off. When you hear the buzzing, stop a fan (I'd start with the northbridge fan) and see if you hear it again. Keep it up until when you stop one the buzzing stops as well.

The technical term for those coils is 'inductor'. They work kind of like capacitors in that they store energy, except that an inductor stores this energy in a magnetic field. Due to the working of those inductors, the wires around the core oscillate very rapidly, which affects the surrounding air and in turn produces the high-pitched sound you hear.

The most common method to make those inductors shut up is to apply some hot glue, lacquer or similar, so that the wires are covered.

good tip, i'll use it later. thx
