ok guys i have got the Xigmatek DK and im so disappointed that i feel like i wasted my money..i did some benches with the stock cooler b4 putting in the DK and honestly the stock beats the Dk in most test..my temps under load with my voltage 1.45, temps go to 65C and more, bsod right after, with stock voltage my temps under load are 58 - 59 Wtf?? also the worst fan to mount, omg seriously,, and on top of that its not even performing right...i did mount it properly though, actually i did it 4 times and did the thermal paste twice, first with the one that comes with the cooler and then with zalman one, same temps. i'll do it once more, as im really concern as i have hear this is suppose to be one of the bets fan..il write again after i do the third thermal paste.
