MP 1,1-5,1 Catalyst HD 7970 Replacement Fan Source

[haralds]

I have a flashed Gigabyte GV-R797OC-3GD that has served me well. However, I noticed a bearing noise at higher fan speeds. Given my system is normally very quiet, this is unpleasant. It could also indicate eventual failure.
Can anybody point me to a reliable source for replacement? I see a lot of seemingly sketchy references.

My Sapphire DUAL-X 7970's rear fan would only spin up for a few seconds. Found genuine fans on Amazon.com

After the replacement both fans working OK.
