Sponsor: Thermal Grizzly Kryonaut thermal paste (on Amazon - https://geni.us/JMVNtOE ) & Hydronaut for water cooling (Amazon - https://geni.us/Fsray ) The Deepcool Assassin IV CPU air cooler is one of the larger towers on the market, but primarily in one dimension -- it keeps the height in check by shoving a 140mm fan deeper into the cooler, allowing better side panel clearance. We tested the cooler with 2 vs. 3 fans, looking at push-pull vs. just pull (technically), and also benchmarked it against other mainstays like the Thermalright Peerless Assassin, Noctua NH-D15, and liquid coolers. The Assassin IV is one of the best air coolers we've tested recently, but it also bears a high price tag. This is a cooler that's sold on the grounds of quality, not value, and so we closely inspect build quality and ease-of-installation features.
