Finished Looks

The Fractal Design Kelvin S24 definitely looks sleek. The black and white design, while safe, also means the cooler should match the color theme of most systems, and it will definitely look at home in one of Fractal Design's own cases.


There is no LEDs to speak of on the Kelvin S24; however, the black anti-kink coils make for a nice change of pace. It is a minor inclusion, but makes for a small difference that sets this all-in-one liquid cooler apart from the competition.


The standard 240 mm radiator keeps the Kelvin S24 compatible with a large number of cases.


The mSATA slot, first expansion slot, and 8-pin EPS plug are all readily accessible. Granted, such is as expected of an AIO cooler, so there is nothing new here. Interesting here is that the Kelvin S24's memory clearance isn't up to the same standard as with other AIO coolers. The default installation requires you to install a stick into the DIMM slot closest to the CPU first as nothing else will otherwise fit. Users are also limited to standard-height memory in that first DIMM slot, at least I was on my test system's MSI Z87-GD65 Gaming motherboard. This issue can be resolved by rotating the pump to have the fittings face toward the expansion slots, which didn't impact performance in any way I could make out. Still, this is an unexpected issue as many other closed-loop liquid coolers manage to avoid it all together.
