Which should you buy, Corsair H150i Elite Capellix or Thermalright Peerless Assassin 120 SE?
The Corsair H150i Elite Capellix suits RGB builds already using Corsair iCUE peripherals and 360mm-radiator cases needing flagship-adjacent cooling, though it is not the pick for buyers wanting an LCD pump display and Non-Corsair RGB ecosystems (Link/CAM users). Take the Thermalright Peerless Assassin 120 SE for budget and mid-range builds up to about 200W sustained. Nothing else at $32 gets close. It is equally the pick for first-time builders. The mounting hardware is genuinely simple and the bundled screwdriver reaches everything. It is not the one for mATX or SFF cases. 155mm of height rules out most of them. Our rating of the Corsair H150i Elite Capellix (8.2/10): A proven, well-rounded 360mm RGB AIO for Corsair-ecosystem builds without LCD-tier pricing.
