Cpu Temp problem

[Harkin]

I have my E6850 Oc'ed to 3.6Ghz. Usually the temps stay around 60C on the cores under load according to Coretemp. I have an AC7 Pro cooler on the Cpu.

So i usually leave the Pc all night folding for Hexus and have had no problems so far. But when I woke up this morning and checked, Coretemp was showing 70C on the cores, which is at least 10C higher than normal. So Ive been fiddling around trying to find the damned problem but it has me baffled. The fan on the AC7 Pro also is not spinning at the Rpm's it usually does when the Pc is at load, usually it spins at about 1800rpm but this morn it was only spinning at 1000rpm. So it may seem obvious that the fan is bust or ill, but I also looked at the temps in Asus Probe and the Cpu was showing a surprisilngly low number under load and so was speedfan. Whats the difference between the 2 core temps and the Cpu temp?

So Im thinkiing that its either the fan on the AC7 Pro or the temp sensor on the Cpu has gone funny, cos if its reading too low then the Cpu fan won't go higher, but it was fine last night. So Im confused at what to do so some help would be great, thanx

Ok so Ive put the system under load and Probe shows the Cpu temp as 33C(it seems to be stuck?), but with Coretemp its showing the cores as 69C and 69C. Is it possible that the Cpu temp sensor has died? Im also assuming that the Cpu has 3 sensors, 1 for the Cpu and 2 for the cores?

What voltage are you feeding the CPU?

Hmm weird things happening on my Pc. For the Oc profile in Bios im so sure I had the Vcore at 1.3250, but now it seems to be on Auto(1.40v), taken form Probe. After changing the Oc profile back to the stock one, and then back to the 3.6Ghz one has made the problem go away. Perhaps last night when I left the Pc it had a bit of a fit cos all the temps are reading right now.

So the Vcore is showing 1,39v now, should I manually set it to a tad less and do a Orthos? Or just leave it on Auto?

Those temps are right for that cooler and that CPU with those volts.

Cheers, think Ill try and bump the Vcore a tad down and see how it goes, even though Auto seems to do fine and temps are fine

Maximum case temperature for that CPU is 72C - the chip temperature can be higher than that. The temperaturte sensor will be measuring the chip temperature.

I read that but still dont know if there are 3 sensors? 1 for each core and 1 on the Cpu somewhere?
Cos in something like Speedfan you can read all 3 at the same time, I was just checking if it was right or a fault with speedfan.
