Check this Heatsink/Waterblock Roundup @ Overclockers.com out. They have a CPU die simulator and test some HSF's on that - http://www.overclockers.com/articles373/

But anyways it looks like that Thermaltake can handle the load of your processor. Just pick up some Arctic Silver 5 (AS5 - nihil mentioned it too) and learn how to apply that to the CPU core / HSF. After a couple of cycles of running the computer hard for a good while, leaving it off until it cools, and then running it again, it will set and temps will improve a bit more before they stabalize. It's good stuff.


And what foxy mentions is good advise too. If you're pulling more air out than you're pushing in, your case is essentially under a weak vacum...and it'll try to pull air in from anywhere. Generally this just results in dust trapped in all the nooks and crannies of the computer case, which is a PITA to clean. Balance is key

Cheers.
