Hey supid question. How do you know if you H80 is installed and working properly? The mother can see the temp @ 41c but speedfan cannot see the CPU temp. I'm running a FX 8150 BE w/ H80 water cooler, 16gb of Corsair vengence on a Asus Formula V crosshair thunderbolt. I've only been able to overclock to 3.82. the Ram Voltage is 1667ish (can't remember exacly but about 1600+) Case is a Thermaltake amour + w/ 5x 140mm 1500rpm and 1x 230mm fans I've BSOD afew time when playing tropico2 and BF2-FH2. WHY. what have I done wrong.
