Compatibility and related parts
Before you buy, confirm your case has a 240 mm radiator mount (the radiator measures 272 x 121 x 27 mm, plus 25 mm thick fans) by checking our PC cases, and that your CPU uses one of the supported sockets from our processors (CPUs). For lighting, your motherboard needs a 5V 3-pin ARGB header, not a 12V 4-pin RGB one. Add it to the PC builder to check compatibility automatically, with free assembly and testing when bought as part of a PC build, and keep some thermal paste and pads on hand for remounting.
