I just bought a ryzen 5 2600x just now new and I guess it comes with pre applied thermal paste now with that being said can i just pop it on in or do i need too apply thermal paste anywhere else this is my 1st time doing this lol
If you're using the stock cooler, then there's no need to apply additional thermal paste to the one that's pre-applied on the cooler itself.
Make sure that the CPU is properly seated into the socket, give it a gentle wigle if needed. Then just tighten the CPU cooler screws(cross pattern) firmly.
