If it's running fine otherwise, then *almost* certainly you didn't break anything, with electronics, outside of a few exceptions, things either work or they don't if damaged. That doesn't mean you should abuse them more than necessary of course ;-).
Ok this is weird, it's still running super hot apparently. Checked todays and each core was 100+ degrees celsius, not sure whats going on. I cleaned off the old paste and applied a pea sized generous amount onto it and sprayed out the cooling radiator really good. Any other advice on what could be causing this?
