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.
Corsair A115
8.2 / 10 Expert Rating
A capable flagship air cooler whose main draw is fitting neatly into an all-Corsair build rather than leading on raw thermals.
