I was thinking of picking up the Noctua NF-A14 iPPC 3000 PWM fans for the Kraken X41 but I need fans for intake in the front of the case - right now I'm just using 2x Corsair LED 120mm fans - they don't push/pull a lot of air.
I was also considering ditching the Kraken X41 for the Kraken X62 - anyone have experience with that?
Only use trio of them so not the forth, but not too much you can do really on these stock coolers as they are tightly packed. I assume you have pulled off the backplate on the other cards in the stack, found that gave it some relief. I have got a pair of fan's (Noctua NF-A14 ippc 2000 RPM PWM fans)) roughly inline with the GPU's and it pushs air down the opening which also helps, though simply put only so much with a stack of reference cards. by the sounds of it you dont live in the same room as the PC so the 3000 RPM would be the way I go and blast air into that case
Would definitely get something better for your CPU, though. Most of the air should be exhausted out the rear so I expect its just your CPU cooler is not up to snuf or you have a serious OC on that CPU.
