CPU = 51 - 63 System = 30c

Hey, I had a computer that was working great until something happened with the usb and the motherboard. Anyways, I got a replacement on the motherboard of the same make and model, cleaned the heatsink and cpu. Applied what I thought was a thin layer of thermalpaste (enough where no metal was showing). My old cpu temps showed ~32 c for cpu temp. This one is showing 54 - 60. 51 when I turned it one. 55 the second time I turned it on. It gets up to 60 when I'm doing a lot of audio. The burn in program I ran got it up to 63. Do you all think that my motherboard temperature is wrong or that I need to redo the thermal paste?

The reason I'm wondering is because the system temperature is the same as before 30c, but the cpu temp is 54 - 60c. You would think that this would heat up the system temp if it was accurate. Please give me your thoughts.

Thanks

What system and heatsink did you have to begin with?

I had the stock heatsink and fan. It cam with the thermalpaste looking stuff already on the heat sink. Which I used for the old board. For the new board I had to use new paste for the old cpu so I got arctic silver 5.

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?

Probably not. Instead it could be that dispite you getting the same model of motherboard as a replacement there are some differences in it. A differently calibrated temperature readout in the BIOS comes to mind.

Doesn't AS take about a week to burn in before it reaches its most efficient heat transfer levels?

Yes, but that normally only knocks a few degrees off, not >20. One thing I can think of: is your CPU voltage still at the default level?

What temperature are we looking at here: cpu socket diode (motherboard sensor) or the actual sensor in the cpu? Motherboard temps are mostly consistently unreliable

Cool 'n' Quiet is disabled in BIOS.

Cheers,

I'm just guessing, but more than likely you have a dh7-cg stepping, and msi wrote a new bios algorithm for temps because the co steppings temps read much lower on the same bios. If you had flashed the new bios on your old board, you would have seen the same thing happen.
