I am a noob so I am unable to post in reply to people's problems with this gawd awful card.

I was mining successfully with one of these cards...then I had the great greedy idea that 2 is better than one.

Got a second card, plugged it in, set it up, started hashing and went to sleep...apparently I blew out the card, and the temps were around 90 all night long.  This cooling set-up is horrible when using 2 cards with out risers in a standard case.  The exhaust air from the bottom card get's sucked in by the top card, super heating the top card.

I got a replacement card, since I'm still greedy for my coins...I put a box fan right on the case and was able to run 75,80 on both cards...700+kh/s on each card...it worked but was not an elegant solution.  After 2 weeks of trying different fans and different settings to reduce the heat, I found a solution.

I got the pwm version of this fan...now both cards run at about 72-73 all day long.  It's hella noisy, but that's the sound of money being made.

One thing I learned about fans...it's not about the rpm of cfm...it's about the pressure...the delta fans will push air even through high resistance.
