Hey guys, I bought a cooler master v8 for my Phenom II 965 x4 BE build. The case is an Antec 300v2. I haven't cooked the thermal paste on there well because I still haven't received the operating system yet (windows 7 pro), but I had the computer POST and idle in bios for about 3 hours. I normally like to prime 95 the computer for 8 hours or so before anything else so it gets nice and hot. Idle cpu temperature is 38 degrees as displayed in the bios, ambient room temperature is somewhere around 73 degrees. I also didn't do the most optimal thermal paste technique because of the difficulty of the back plate, then flip the mobo and put the CM on then screw down, so instead of a small bead of thermal paste, i have a small bead of thermal paste that I smoothed on with a plastic covered finger. It still is an optimal quantity but I like having the pressure spread it rather than spreading it myself. I would like to see a lower idle, I was wondering if changing the CM V8's fan to a higher RPM fan would increase the cooling possibilities. I was hoping for an idle around 32. I went with the CM V8 because I liked the way it looked in my Dad's case and he was getting decent temperatures with his i7, so I am aware there are better heat sinks but the design aesthetic appealed to me . Thanks! PS the antec 300 v2 has the weirdest power supply mounting problem: my Thermaltake TR2 700w power supply wouldn't fit (neither upside or downside)! I had to drill out 4 rivets and remove an angle brace at the lower back corner of the case!!!! Once this was done it fit fine.
