A dependable, genuinely quiet single-tower cooler that's been slightly outclassed by be quiet!'s own newer Dark Rock 5, but still a solid mid-tier pick on sale.
Cooler Master MasterLiquid ML240L V2
7.6 / 10 Expert Rating
A dependable entry-level AIO that looks better than its price suggests, best suited to mainstream builds rather than high-TDP flagships.
