I overclocked my Athlon II X4 to 3.12GHz on the stock cooler, 13x240, FSB RAM ratio of 3:8.
My idle temps went from 44 to 48, and on running everest's stress test, for around 5 minutes, it hit 63. Are these dangerously high?
Ambient is usuallt in the 25-35 range.
Might it have something to do with my GPU? It blows air directly onto the CPU.
I have it underclocked most of the time- it still idles at 55.
On load, with full clocks, 80 is usual.
Load, with cut clocks, 63.
Like Herr_Koos says, better CPU cooling will always help. Have you upped your CPU voltage for your OC?
The CM Elite 335 has space for 1 front and 1 rear 120mm fan which would help if you havn't already got them.
Have you tried adjusting the 4870 fan speed in ATI Catalyst Control Centre, my 4850 was at a default setting of 30% and used to hit 90C until I ramped the fan up to 50%. Ended up putting an Akasa Cool Blue on it, dropped 20C.
How does your GPU blow air directly onto your CPU?
I dont want to burn out the fan. Either way, on VMax it sounds like a vacuum cleaner.
Mine isnt the dual slot version that blows air out of a vent. It takes in air from the side vent, blows over the gpu, and right above it, slap bang onto the CPU fan's intake path.
It was one of the last 4870's before it was discontinued......what do you expect?
Either way, I'll need to get a bigger cooler right?
Any recommendations within a USD60 budget?
