INTRODUCTION

   Ever since i got my hands on a AIO liquid CPU cooler (if memory serves me right i think it was the Domino A.L.C by CoolIT systems) just over a decade ago it became clear to me that their introduction meant that liquid cooling would not be considered "niche" for much longer. On top of that even though back then cooling efficiency wasn't really anything to get excited over (always compared to some of the air coolers released at that time like the NH-D14/V8/V10 models) unlike air-cooling there was obviously much more room for improvement. Today the market is filled with AIO liquid coolers and since one of the most popular lines as i type these lines is no other than the Celsius+ Prisma by Fractal Design after testing their quite impressive S36 tri-fan model (review here) today I’ll be testing their S24 and S28 dual-fan models.

   Fractal Design is a leading designer and manufacturer of premium PC hardware including cases, cooling, power supplies and accessories. Based in Gothenburg and with offices in the US as well as Taiwan, Fractal Design has gained a global reputation for innovative design, elegant aesthetics and solid build quality. Fractal Design products are available in over 45 countries worldwide, and are still growing.

   Just like with the S36 model the Celsius+ Prisma S24 and S28 models are also most likely manufactured by one of the leading companies in the field, Asetek. Now leaving out the Celsius+ Prisma S36 both the S24 and the S28 feature aluminum radiators with the same FPI count (21FPI), the same 400mm long sleeved tubes and the same ceramic pump that can reach speeds of up to 3500RPM with a maximum pressure of 1.46m H20 and up to 20dBA of noise. What changes between both models is obviously the size of the radiator (284x122x31mm for the S24 and 324x143x30mm for the S28) and the fans used so Fractal Design has paired the S24 model with two AL-12 PWM RGB fans (120mm/2000RPM/85.71CFM/2.78mm H2O/32.7dBA) and the S28 model with two AL-14 PWM ARGB fans (140mm/1700RPM/103.9CFM/2.38mm H2O/34.1dBA). Needless to say, the ARGB system is pretty much identical for all 3 models so aside the ARGB controller found on the radiator they feature the same 6 addressable RGB LEDs beneath the glass top of the pump/base combo and 6 addressable ARGB LEDs on each of their fans (fully compatible with all the major motherboard sync technologies including Gigabyte Fusion, ASUS Aura, Razer Chroma, MSI Mystic Light and ASRock Polychrome). As pointed out in the S36 review the entire Celsius+ Prisma line is covered with the same 5-year limited warranty.
