Hi,I get idle temps of around 50°C for the cores and 40°C for the CPU when stressing a bit it goes up to 80°C.

No way to change it.
I reseated the heatsink and put new thermal paste about 10 times without luck, same problem with the stock cooler.
The one I use now is AC Freezer Xtreme Rev.2
Do I miss something?

The CPU temp is on the IHS. This temp is generally ~5C lower than the cores on an i7. My temps get up to ~75C on load with 3.6GHz with HT on. My CPU temp is 70C and cores are ~75C. Turn the AC on and the fan speed up. Your FIRST problem is the stock cooler. Take it off, buy a new one, preferably the one that I have, and use the stock one as a nice paper weight. It can cool your desk just fine...CPUs...not very well.

I am using an Arctic Cooling Freezer Xtreme Rev.2...not the stock cooler (with turbo mode on to get the cooler to run faster) and I get 80°C when stressing it just a bit.

I didn't overclock all on stock speeds, and I get higher temps than you do.

Did you thoroughly clean both contact surfaces before applying the thermal paste?

I did every time, even used different kinds of thermal paste, but none would help.

Could my mobo be causing this?

I have the same issue with my Core 2 Quad and I have a mugen heatsink.

Probably broken temperature sensors.
