Just picked up an ASRock939 and an Opty144. I went to install them today and im not to happy with how my SI-97a installed doesnt cover all the heatspreader and it only has top retention which seems kinda iffy to me. I havent got an good temps yet but is there something better out there then a SI-97a? Its off my barton 2400 was the best hs i have right now so just lookin to see if there is somethin better out there. i current have a nice panaflo 90mm fan for it also so if there is one that takes a 90mm fan that would be great.
