Can you still RMA your GPU? Coil whine shouldn't be happening and usually isn't a good sign. What's really odd is that it's only happening with 1 game and not others. Let alone for a game/mod like Brutal Doom with an older graphics engine. Very odd.
You don't hear coil whine with any other game??
coil wine can happen with any piece of hardware even brand new out of box. not to mention that companies usually won't RMA for coil whine.
Wow thats so annoying! I would pull my hair out hearing that. I have an aneurysm when even 1 of my hard drives makes a sound out of place.
@me1212 - If it only coil whines for 1 of your games, then its not even that big of deal. If it doesn't bother you too much then I wouldn't worry about it too much. Me? I'd probably drop kick my video card out the window.
