Well I just finished building my comp and booted it up into the bios (Asus P5B Deluxe, its a core 2 duo e6400 btw). My CPU temp is showing a 42C temperature. I cleaned off the heatsink wax and used Arctic silver 5 instead, which I was hoping would get me around 27C idle per reviews. I followed the directions on the side and put a thin strip down the middle where the duos would be. I just used rubbing alcohol instead of the arctic cleaning stuff they sell though, which could have been one reason maybe. I'm just wondering if I should clean off the arctic with their own cleaner and try again, or maybe buy an aftermarket heatsink now that the wax is off... anyone had any experience with this? I'm planning on OC'ing obviously so I don't want it to be running this hot before I even do anything... Oh and does anyone recommend putting this on your video card also or is it really not needed. I noticed of the reviews people were using it on their video card also. I'm running a radeon x1900gt 256mb 256bit 16pixel.
