Doing my first PC build soon and settling on a i5-8600k. Now i'm not looking at overclocking for some time in all honesty, but buying the i5-8600k based on the speed advantage it has over 3.1ghz i5-8600 for a small price. Is an additional fan a requirement for it even though I am not overclocking? If it is, recommendations as to which one? Case I am using is by GameMax, the Knight, and has 3 fans already. PSU, if relevant - is a Corsair HX850i.
