A Closer Look

The Kelvin S24's copper radiator uses a low FPI (fins per inch) design. At just 14 FPI, the radiator's fin density is much lower than on the Corsair H105 or Deepcool Maelstrom 240 - these sit at, respectively, 20 and 18 FPI. Such a low FPI should result in less noise as the fans provided by Fractal Design do not need as high an RPM to force air through the radiator. The tubing is 320 mm or 12.5 inches long, and while it may look like FEP tubing from a distance, it is in fact smooth and includes anti-kink coils, which is something I have yet to see on other all-in-one liquid coolers. The radiator use G 1/4" fittings, which also makes expanding the Kelvin S24 an easy feat.


The pump and CPU block are sleek and clean-looking. Like with other AIOs, swivel fittings are used, though these are two-part brass fittings. The base is made of clean, smooth copper, which, while not polished to a mirror shine, is still a step above many other currently available liquid coolers. The only thing to dislike here is the 3-pin pump power cable. Its sleeving does not quiet fully cover the wires. As such, wiring is readily visible and stands out, thanks to the black and white design.


The seven-bladed Silent Series HP 120 mm fans have the model number FD-FAN-SSHP-120. They feature PWM and have an RPM range of 800-1700. The cables here are also sleeved, and unlike the pump, their sleeving goes right up to the PWM connector. Their wiring is only visible near the frame, which, with the cooler installed properly, nicely hides them from view.
