Verdict
DeepCool Assassin IV
8.7 / 10 Expert Rating
A genuine flagship-tier challenger that gets DeepCool most of the way to Noctua-level cooling for a fraction of the price.
Noctua NH-U9S
8 / 10 Expert Rating
A sensible, well-built compact cooler for mATX builds that don't need flagship-level thermal headroom.
