My artic 240 is enough for my 14700kf, even during cinebench all core load. Albeit with a fairly aggressive undervolt. But even without the undervolt, would still would be fine for games and most real world tasks.

I am using a 240 AIO on a 13700k. It handles it fine. It does get very close to the throttle point during all core bench marks but it in all real world usage it has been fine.

Be quiet 360mm is like 90 bucks on Amazon
