I touched the heat sink and it's definitely not as hot as boiling water. Could it be over time the heatsink doesn't have a proper seal with the CPU?
Since this page doesn't use Flash the temps are both now 72C, with Everest saying it's 61C.

Depending on the age of the system you may need to take the fan off and clean the top of the cpu off. Apply a new pea size drop of thermal paste and then put the fan back on the cpu.

The thing is though I've done this 4 times in the past 6 weeks, the last time using a blob roughly the size of a grain of rice 2 weeks ago and it seemed to fix the problem, but very recently it's started again. Very annoying!! Both cores appear to be relatively even in temperatures, but getting up to 100C is ridiculous. It's been quite warm weather wise the past week, but surely it shouldn't climb 20+ degrees higher than a week earlier when the weather may be up to 10 degrees higher?

I think I have a theory as to what's happening, someone more knowledgeable may be able to either support or refute it, either way it would be helpful.
Each time the problem is fixed (twice now) one core always runs hotter than the other by around 10-15C.
When the problem comes back both cores are running a lot hotter but at the same temp.
When I remove the heatsink the distribution of the thermal paste is uneven, with it being normal on one side and almost not there on the other.
Theory: the hotter running core is thinning the thermal paste till they both run at the same temp, but because the thermal paste has thinned it's not transferring heat properly and thus an overheating problem occurs, hence a faulty CPU.
What do you think?

Putting to much or to little will result in the same symptoms you are experiencing.

If the problem occurs again (which it probably will going by past history) I'll report back.
