I currently have a Intel Core i5-12400F (bought a pre built from Starforge) and am thinking of upgrading to an Intel i9-14900K or KF and I’m wondering what steps I need to take in regards to preparation and during installation
I bought a bit of thermal paste a while back that was a corsair one that I saw in Walmart for cheap, but if I need better I’ll get better, I also have a Arctic Freezer 36 Air Cooler


‘Good’ as in it will probably work, but getting a KF is unnecessary unless the motherboard suppkrts it and if OP wants to overclock.
And assuming the prebuilt has proper power overhead means TDP won’t be an issue but it’s worth keeping an eye on.
