I have a pair of Ultra Kaze 3000rpm 120mm fans...they blow about 133 cfm. I think there is only one fan with a higher rating. I run my rear fan at 2.1k rpm and from at 1k rpm. My question is...should i reverse my heatsink and rear fan to blow towards the front and have my front fan blowing air out the front instead of in? Has anyone else tried this? I just got my e6750 to boot at 3.7ghz. got a 14.129 1mb Super PI mod 1.5. It wasn't stable, I think it got way too hot from my temps...65C. Hyper TX2 Cooler. Any feedback would be appreciated. Thanks
