Verdict

ARCTIC Liquid Freezer III 420

9 / 10 Expert Rating

One of the best value-per-degree AIOs available at any radiator size, now in its largest non-Pro form.

NZXT X63

7.5 / 10 Expert Rating

Solid 280mm cooling with NZXT's signature look, best for cases sized for 280mm rather than 360mm radiators.
