After spending two hours working out Pobability, Reliability and other really intense equations, my Tyan just turned off. No BSOD no warning, just off. I opened the case and it was baking. Both graphics cards at 65°C CPU's at 58°C & 60°C. The ambient case temp 40°C. So, what better time to upgrade the cooling. Easy yeah........not. With so much out there who's the best. Best = Value for money+Efficiency+Compatability / Looks-Size. WaterChill High End CPU/VGA/Chipset Cooling Kit - 120mm Radiator/Fan (03-L-1307) (WC-036-VP) £164. This looks a good option. Two of these each end of case cooling CPU's & GPU's. Or buy individual parts and assemble. Any thoughts, ideas, suggestions, comments etc. welcome. Cheers.
