Got the heat sink today- and (drum roll please)
IT SUCKS!! Ok no seriously it's ok, but the fan on it is as good as a 27cfm ystech or a 28-29cfm adda fan. It certainly does not even approach the power of the delta black label fan. It is quieter though. I put it on there and just watched the heat rise. So i combined the fop32 (ys tech 27cfm) fan with the volacno 2 fan with a case slot bar and some superglue and the two fans together cool the same as, if not a tiny bit better than the delta fan, and much quieter too.
