hello, i recently bought a macbook a1278 2011 13"with an i5. I replaced the thermal paste with mx 4. And the temps when watching youtube or starting laptop up reach 99c then it throttles down. There is no dust and the fan work just fine. I tired ramping the fan speed to the max and the temps still reach 99c. What should i do?

What was it hitting before?

If you are seeing worse performance after a new thermal paste application, the problem sits with either the paste used (unlikely) or the application process (like remounting the heatsink).

If you don't have a baseline 'before' test.... I'd have to assume it's the application/mounting/pressure.

Before thermal paste change I was seeing temps over 85c idle now - 50-60c idle. I applied enough thermal paste and i tightened the screws pretty well. I think the cause could be the heatsink or the cpu overvolting somehow.
