I recently upgraded my system from the ground up, with a thunderbird 1.2ghz (266fsb) on an MSI k7t266 mb - also a geforce2 pro 64mb video card. I have some decent cooling - 4 fan case and thermaltake superorb on cpu, with blueorbs on the chipset and gpu. Nevertheless, the combination of noise and cpu temps have drawn me to watercooling (even non-OC'd, the mb sensors read my chip as running at 48-51 degrees C!) Obviously, this is not healthy. First off, has anybody heard anything about MSI board sensors being inaccurate?...I've heard about asus's being way off. But anyway, as for my main questions: For a watercooling system, would a TEC add significant benefits, enough to warrent the extra cost? Also, I'm wondering about water blocks for my gpu/chipset. Is this worth the cost and should I bother with TECs for these, too? Any help would be greatly appreciated.
