No problems with sapphire here.
7950 are crap cards (they're failed 7970's) I don't use them.
When the fans die we just strap 92mm case fans on with cable ties.
Man you really have it in for those 7950s don't you
- did they murder some other cards?
Doesn't matter as both 7950/7970 are pretty much gone now.
What I did for my failed 7950 was take the fan out and mount a 120 near the card - same effect. RMA with Sapphire seems like it would take a month - would be cheaper to just buy a new fan.
