Coil Whine

post #1 of 2
Thread Starter 
Now this ones going to make everything laugh but hey we gotta try

My 7950 (powercolor pcs+) has really bad coil whine and as I bought it used getting an rma wont be easy so rather than trying to rma I would like to try and fix it

My question is can I just replace the coils? Surely this will cure my problem?

Where could I get them from? How much would they cost? Are there cheap faulty cards I could pull coils from?

Looking at the high res pic here: http://www.techpowerup.com/reviews/Powercolor/HD_7950_PCS_Plus/images/front_full.jpg
I can only see Magic R22 written on it so that doesn't help to find the part...

Don't bother trying to replace the coils. It is not worth the hassle. I know people complain a lot about coil whine on these cards, but it seems until recently people have been expecting high end cards not to have it. My 9800GTX+, GTX 260 55nm, GTX 560 Ti, and HD 6950 all have coil whine under high loads or very high frame rates.

Also you won't be able to get ahold of the proper coils unless you want to buy them in a tray of 1000.
