Well, installed it and I am gettin the same temps I did with my old heatsink/fan 40/50. Put As5 on there 2 bb drops spread it around, tightened it on there real good. 2 90mm 85cmf fans turned at half speed, full speed makes no difference. Do I have to wait a couple days for the temp to drop or what? Otherwise ***? These temps are according to Speed Fan, but even if it was lying, that means my other heatsink was just as good.
