WHY so hot??5/5/2013 9:05:14 PM

Pros: Runs games smooth. It is a well built card and comes with a clock of 1000. Handles any game I throw at it magnificently. The "buzzing/whining noise" I mention below has actually improved with time. XFX support PRE changing their support site was excellent.

Cons: SO hot. I have a Mining Rig with 3 Sapphire 7950s going at a consistent 70 to 75 C, hashing at 1800 about 600 each. I can overclock the sapphires higher then the xfx with a lower temp. Whenever I mine with the 7970 it runs 80C + with a terrible hash of 370. Oh and when the fans go above 75% they start with a TERRIBLE whining noise while the Sapphires make very little sound at 80% fan. Also I should mention that I RMAed this card twice already for artifacting/buzzing coil whine and am in the process of RMAing again. XFX seems to have lost my ticket number when they took down their support website, and have been pending with the resubmitted ticket for 2 weeks.

Awesome card, but defective9/10/2012 11:05:40 PM

Pros: Love the card itself. Extremely powerful, runs fairly cool for such power as well. Already stock overclocked which is also awesome. Looks sexy.

Cons: Under load would make a electrical buzzing sound, eventually began to flicker in and out of black screens, artifacting etc. RMA'ed well see how it goes with the second one.

Hello, This "buzzing" is referred to as coil whine. Its an anomaly of sorts and typically develops over time. Our warranty protects customers from this strange occurrence so they can get it covered and get back to business. If you have any further questions about your RMA, please use the ticketing system or contact mark.regimbal@xfxforce.com
