Just got one of these from a friend... http://www.ultraproducts.com/applications/searchtools/item-Details.asp?EdpNo=4143848&sku=ULT40494 and my temps on my Phenom II are now a handful of degrees higher than what I had when I was using my TT Big Typhoon. It does use a bolt through deign, so I suppose the cooler could be mounted unevenly... I just tightened all the bolts by hand until I couldn't get them to go anymore. I suppose it's possible to be worse... it seems like the cooler has a rather inefficient design. It only has 4 heatpipes, and 2 of them go to the tec plate, which in turn go to half of the fins. The other 2 are going to the heatsink base with the other half of the fins. So, in essence I only have 2 heatpipes on my heatsink base where before I had 6... and quite a deal less fins. Also, the fan is only 92mm, where before I had a powerful replacement 120mm fan. Anyone have experience with this cooler? Would you expect ~50c load from a Phenom II at these settings? I've noticed the pins have slots in them to use a screwdriver to tighten them. Should I do that? more pressure between the cpu and heatsink could always mean lower temps, but it also means more pressure in the motherboard... if I tighten them with a screwdriver as far as they will go don't I risk damaging my board? How do you guys with bolt through setups usually handle installing these?
