Compatibility and related parts
Before ordering, confirm your case has room for a 240 radiator: the radiator measures 272 x 121 x 27mm, and the 25 mm fans add to that thickness, so check the radiator support listed for your case among our PC cases. You will need a 4-pin PWM fan header, a 3-pin header for the pump and a 5V ARGB 3-pin header for the lighting. Pair it with one of our processors (CPUs) and fresh thermal paste and pads, or add it in the PC builder, which checks compatibility and includes free assembly and testing when you buy it as part of a PC build.
