Is it possible to have a cpu temp of 60c and a sys temp of 31c? I just replaced my motherboard with the same make and model. I cleaned up the cpu and heatsink tha was on the old motherboard with a credit card and alocohl and then applied the new arctic silver 5 paste with a credit card so that no metal was showing (but I didn't think it was too thick). My old cpu temp was 32c with a sys temp of 30c. This one has a cpu temp of 53c to 60c with a sys temp of 30c. You think that with that cpu temp that my sys temp would be hotter. So my quesiton is do I need to redo the thermal paste or is my new motherboards thermo messed up.

Thanks

It is possible if the motherboard temp gauge is away from a cpu that has an improperly installed heatsink or fan. I would take off the heatsink and reattach and make sure the fan is blowing down into the heatsink and not blowing up and away. It can happen!

Ok, I redid it this time. I spent 45 minutes cleaning the cpu and heatsink with alcohol. Instead of applying the paste all over the athlon 64, I did it like arctic silver 5 recommended: put the thermal paste in the middle about 3/4 the size of a bb. From a cold start, my system temperature iwas 26c and my cpu temperature was 51c and is now 53c, but I haven't run any big applications yet. The cpu is a non-overclocked athlon 64 3000. I think my cpu's thermometer is mesed up. What do you all think?

what model motherboard? i know the msi k8n platinum (nforce 250) bios prior to 1.40 gives erroneous readings on the cpu with newcastle . It could be the motherboard, too. Mine originally had similar high numbers, then after flashing to the most recent bios, mine dropped into the 40's immediatly

here's someone else in your boat

yeah, I have a chaintech vnf3-250 with phoenix award bios v6.00. my old chaintech vnf3-250 didn't have this problem, but it could have been a different bios version

A BIOS update should solve your problem. If not then you may have to get your motherboard replaced because of a faulty monitoring chip....
