i am having some trouble with my cpu temps and i'm starting to suspect the length of my system tubing. no cheap shot please! =) i have my radiator at the top of my case and my pump at the bottom and i imagine i have 6 to 8 feet of 3/8" ID tubing with an ehiem 1048 and dd cooling cube. i'm setting about 45C CPU as reported by the bios. i've tried reseating my block and am now wondering if i need to cut down on my tubing. is it way out of spec - ballpark wise?
