I upgraded from the AMD HD 6950 to the Sapphire R9 280X Vapor-X OC and found that card a tad more noisy than my 6950.
I was thinking that was normal bcs the higher performance is more power expensive and thus needs higher rpm coolers.
I was mistaken bcs it came out the cooler had a defect making 1 of the 2 Fans stop and the second Fan had to do the work for both at insane rpm.
I got a new replacement card now and while playing games (especially MWO) it stays almost silent at the "Idle Desktop Noise Level".
Its really night and day!
So if your new GPU becomes loud in games it may be the Cooler is not working...
