Random coil whine at idle

post #1 of 6
Thread Starter 
Title says it all. I am using a Radeon 7970 HD from Sapphire, and the card whines randomly for seconds at a time, on and off, even when not playing games. Why is it doing this? Should I RMA it? I have had it three months or so and it JUST started doing this. I just got a new motherboard and reinstalled Windows 7 Professional recently.

If you can RMA it I would. The coil whine will usually get worse over time. If it's a great card otherwise and you don't mind invalidating the warranty, usually a dab of silicone around the offending inductors can cure the problem (if you can identify the exact culprits).

Also be advised that if you plan to RMA the card you might concoct another reason that coil whine for the return, as some mfgs. don't like to RMA for that reason.

A couple other things you might try that I've read can help (but can't confirm this on my own) is to enable v-sync or cap frame rates to keep the card from severely over-shooting the frames per second that your monitor is capable of displaying.

That is strange, because my cards only do that as the above poster said: when the frames shoot into the hundreds. Skyrim menus are the worst culprits.

So do I need to RMA it back to Sapphire, then? How long does that usually take? Like 3 weeks?

The only problem with the RMA is that the replacement card could have coil whine too. Worth a try I guess.
