Thats an extreme air cooler lol
For that price, its better to get a water cooler for a little bit more.
An update on my system.
My gigabyte ma790gp-ds4h board had to be rma because the booting is driving me NUTS!!!! It was taking 3-5 mins to even post at stock speed. When I first had the board last month it took about a minute to post. The time it takes kept going longer and longer. So now I have a DFI DK 790fxb-m2rsh which is excellent
Though im kinda stuck at 3.7 ghz, only because if im running back at 3.914 my load temp is 60c!!!.
Im using the supplied grease that came with the xigmatek, since I ran out of ocz freeze.
But once I get a tube, I will try getting to 4ghz again
