Oh i realise rn look at thatMight help if the was at least the stock cooler. The Wraith Stealth isn't that bad, but what Op has isn't a Stealth. It's not even AMD stock. Not sure what it is or where it came from, but from the design, it's probably worse than stock but came with promises of being 'better than stock
Actually i didn't cpu cooler unscrews. I just keep with it when i remove the motherboard. As i said i have the cheapest thermal paste but i can try it to test cpu temps.You pulled the cpu off. You have to clean off the old paste and apply new. Doesn't matter what paste, as long as it was designed for cpu cooler use.
