OK i have: - Athlon 1.33ghz - 512mb PC133 - Vivid!XS - Abit KT7A-RAID mobo - SB Live! 5.1 and i decided i wanted to overclock a bit, but then i looked at my CPU temp and it was running at 51º before id even started, so i overclocked anyway and the temp got to bout 58º overclocking it to 1.4ghz! So i took my PC apart took off the heatsink and tried putting a different amount of thermal grease on my CPU. Did that and not a lot changed! So i then took it off again, put on a thermal pad, and put a small amount of grease on the core! But......... i also put on an old 5000rpm K6-2 fan, atached to the side of the heatsink facing the wrong way, so it was sucking air off the heatsink And now it runs a 1.5ghz, RUNNING AT 33º. WOW Just an idea for u lot Has anyone else ever put 2 fans like that on the heatsink??
