be quiet! Shadow Rock 3
8.1 / 10 Expert Rating
The strongest cooler in be quiet!'s Shadow Rock series, and a genuinely quiet single-tower option for buyers who put acoustics ahead of maximum thermal headroom.
Thermalright Peerless Assassin 120
8.5 / 10 Expert Rating
An excellent value dual-tower cooler in its own right, just slightly outclassed by Thermalright's own SE variant when both are priced closely.
