I just received the new revision of the Asus P67 Pro motherboard for my i7 2600k. Until I installed the replacement motherboard my system was running excellent. I installed the new mobo and on the opening boot screen it said my CPU was overheated (about 5 sec into startup). When I got to the bios the tep gauge said 205 deg cel.
Is that even possible in 15 seconds? Why would it go so high so fast when the heatsink fan is spinning like normal?

Build:
i7 2600k
Asus p67 Pro motherboard
16gb patriot gamer 2 RAM
stock heatsink
2 x 1TB Samsung Spinpoint F3
1 x 64GB Crucial C300 SDD (OS only)

All I can think at the moment is that:

- the heatsink is not seated properly upon the CPU.
Remove it and reseat it please.

Ok, I reseated the heatsink and applied a fresh thin coat of AS5. Still booting at 97 C and will not come down from there. I have three fans and a heatsink and they are all blowing normal.

Should I try a different fan even though it is still running correctly?

Download CPUZ and tell us what it reports in CPU temps.
Also Download HWMonitor and see what it says (TMPIN2 is the CPU)

Coretemp is actually the most accurate temp monitor I know of. CPU-Z does not monitor temps.

Do you have a stock cooler or aftermarket?

I have a stock cooler. But I just came back from the store with an H50. I have not installed it yet. I asked the guys at CompUSA and they said it could be a problem with my motherboard sensor. I let the system run for 3 min, took out the fan and felt it and it was not hot at all. Does this mean that the processor is not 97C?

Can you boot up and see what Coretemp says? It very well could be a bad sensor.

Ok I just installed H50, started up at 73 C but then said fan error and started to climb quickly. I shut off the computer. I am investigating now what it may be. Any ideas?

Brother, you might have a bad motherboard!

Im still on the fence about the bad motherboard because right now the CPU is at 46 C with the fan set to really low speed. I am trying to figure out how to increase the speed. 46 is getting closer to normal right?

Yes, moving in that direction.
If you want full speed on the fan, disconnect it from the CPU header, plug the case fan into the CPU header, and plug the CPU fan into a PSU rail. It should already have a connection for that or have come with an adapter.

Well, maybe it is. I restarted and the CPU was 80 now it has fallen back to 60 but wont go any lower.

Yeah which makes me believe there may be a problem with the motherboard. I just readjusted the fan plugs. Put the CPU fan plug into the power fan plug, restarted and now I am back around 35-38 which is where I was before I readjusted to fan plugs. Interesting corelation that I do not understand.
