I have a pentium D 925+ 3.0ghz cpu asus p5p800 se 520 watt psu 1 gb pc2700 ddr (2x512) 2x 200gb sata drives 256 nvidia video card. case with six fans. And I'm gonna install a sound card with a 10/10 I/O outboard.
Applied thermal paste between cpu and heatsink. Booted PC, went to bios where it reported it was running at 38c. But this temperature keeps rising. And after about 15 minutes it was up to around 50c.
Have I applied to much paste or could the problem be something else.
50c is OK as long as it's not going to start climbing to the 60's. Cas fans will not do much for the CPU. And never found the need for them. If you want to bring the CPU temp down then you concentrate on a CPU cooler first. # Start by having a Read in click here
correctly Flat and not a little of horizontal flat. I would start to worry if it goes above say 60c mark, could be a poor quality HSF or maybe one that is not matched for your CPU unless you got it as a retail CPU.
Also take it you have plugged in the fan to the Mboard header.
what version is your Mobo bios? According to the Asus site the mobo requires bios version 0803 or higher to support your cpu. It's conceivable that this could affect cpu running temp, or more likely the accuracy of the temp reporting in bios.
If you're using the heatsink / fan supplied with the retail CPU, I can't see any way of mis-aligning the thing, and if all 4 feet are locked in place it looks idiot proof. It should be cooling it better than your temps indicate.
I hesitate to ask this, for fear of causing offence, but you have taken the plastic lid off the cpu socket lid thing, haven't you? Called PnP cap according to your manual
