GPU Cooling issue

[SabaII]

Hey guys so I installed two 660s and they seem to be running hot. They were just pulled out of my biddies rig where they ran fine and stable over clocked slightly. My Air 540 has 2 120mm fans out of a 900d and a 120mm H50 on the intake side and the two stock 140mm fans up top exhausting and one 140mm stock fan shooting out of the back. The card heatsinks are clean as well.

Kind of banging my head against the wall here. Running in WoW on ultra settings they want to run around 80c unless I got in to the program and turn the fans up to 70% on both cards then the come down to about 63c which makes it pretty loud even with my headset on. The cards are no longer over clocked in my system and running a good bios. Drivers are confirmed good.

The only thing I have changed is I took out my HD6770 and installed the two GTX660s. I will update my sig to my current system specs.

The solutions I can think of is to move the H55 to the exhaust side and run more positive pressure. If I need better fans then I need to order them and would like to know some opinions. Thanks in advanced!

its kinda normal for sli/cfx to run hotter. not a whole lot can be done about it, possibly add a side fan for fresh air onto the cards?
your temps arent really too bad, not high enough to really be worried though

Are both cards running similar temps?

Do the motherboard temp(s) rise substantially under GPU load? If so, by about how much?

Well I was also having an issue of my video cutting out at random. I thought it was temperature related but after doing some more monitoring and research I figured that they were two separate issues. I dug a little deeper and did the delete of the two WoW files that the game creates upon log in. I also reinstalled my drivers. Once I fired up the game I set ultra settings and turned the AA down to 8x and I read that is what the GTX660s support. My temps seemed to come down to the 65c range with relatively low fan speed. I was only able to play about 30min after I did all of this but did not have any issue during that time. Tonight I will know if it fixed the problem 100%. Thanks for the input.
