Fractal Design Celsius S24 Liquid CPU Cooler Review

We will be testing the Fractal Design Celsius S24 on our brand new Z270 test system which is made up of the following components.

Fractal Design Celsius S24 Liquid CPU Cooler

Processor: Intel Core i7-7700K
Video Card: MSI GeForce GTX 1060 Gaming X 3GB
Motherboard: Aorus Z270X-Gaming 9
Memory: Corsair Dominator Platinum DDR4-3200 16GB
Storage: ADATA XPG SX930 240GB
Power: Corsair AX860i
Cooling: Fractal Design Celsius S24
Case: Primochill Praxis Wetbench

We will be comparing the Celsius S24 to these three other all-in-one coolers.

Corsair H100i
NZXT Kraken X52
NZXT Kraken X62

Our first test will be our idle test. This is taken on the Windows desktop an hour after initial boot up.


Next we have our gaming test. To simulate normal gaming conditions we run Heaven Benchmark on loop for 1 hour.


Finally for our load test we use Prime95 to put 100% load on our CPU. This will simulate high CPU workloads such as video encoding etc. This test was also run for a 1 hour.


If we look at these results the Celsius S24 is pretty much on par with NZXT’s Kraken X52, which is also a 240 mm cooler. The Celsius was definitely the quietest out of the group, with the NZXT coolers coming in second and then the 3-year old Corsair H100i sounding like a jet taking off at times.
