Verdict

be quiet! Dark Rock 4

7.9 / 10 Expert Rating

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.

Thermalright Peerless Assassin 140

8.6 / 10 Expert Rating

One of the best price-to-performance dual-tower coolers available, now with larger fans for extra headroom.
