I just switched from my Xigmatek DarkKnight to my new Corsair H100 and I don't think it working right. I mounted the radiator at the top of my case, with he fans mounted right above the grill pulling air upwards through the radiator. I used arctic silver on the block. With stock clocks on my i7 930 it idles at 50C and when I run prime 95 it gets to 100C. The lights on the block light up and I can hear liquid moving when it boots so i know its flowing, and the fans are definitely running. what could I have done wrong?
