Thermal Paste Expired?
So I put together the PC about a year and a half ago.
I recently got into overclocking, and wanted to re-apply thermal paste on the cpu to try and see if it would help temperatures.
I think I have a decent Haswell 4670k chip for overclocking, as earlier I was able to get a stable 4.7ghz overclock with a max temp of 75-80 in stress testing (never over 60 in gaming), and at a core voltage of 1.262v. (air cooled, push-pull hyper 212 evo, arctic mx-2)
Then a few weeks ago I went and put some fresh thermal paste on and now it's no longer stable at that clock.
And it's hotter than i've ever seen it. A 4.4ghz overclock will get up to 100c and start throttling down!
I re-applied the paste again today and found that most of the paste was bunched up on one side of the heatsink and cpu, so I tried to reinstall the heatsink more level so to create an even spread. But the temperatures aren't much improved.
I've noticed, that the heatsink doesn't get warm when the cpu is working under full load anymore. Before I could stick my hand in and feel how warm the heat sink is, but now the cpu will throttle at 100c and the heatsink will feel like room temperature.
This leads me to think there's some issue with the thermal paste drawing heat away from the cpu.
I have had this thermal paste since I made the machine almost 2 years ago. Should I get some new stuff? I'm planning to switch to a corsair h100i loop for fun...
