Which should you buy, Arctic Liquid Freezer III 240 or NZXT X63?
Take the Arctic Liquid Freezer III 240 for buyers who want genuine liquid-cooling value in a compact 240mm form factor. This is widely regarded as the strongest value pick in this exact category. It is equally the pick for compact cases that can't fit a 360mm radiator. The 240mm size opens up liquid cooling to a broader range of case options. It is the wrong buy for the hottest, most demanding CPUs. The Arctic Liquid Freezer III 360 or Pro 360 ARGB, both covered elsewhere on this site, offer more headroom for sustained high-wattage loads. Buy the NZXT X63 for 280mm-radiator cases and NZXT CAM ecosystem builds, though it is the wrong buy for cases with 360mm radiator space available and buyers wanting an LCD pump display. Our rating of the NZXT X63 (7.5/10): solid 280mm cooling with NZXT's signature look, best for cases sized for 280mm rather than 360mm radiators.
