I've just dished out £1000 on a gaming PC build, both Linus & my friend are saying to remove the thermal compound already on the CPU & replace with a paste you bought yourself, but I'm watching another video & this guy is saying Corsair CPU coolers already come with good quality paste on them, so don't feel the need to clean it off & replace it with your own, what is best to do? I have a h110 cooler and an i5 4690k, if it helps?
