Review: Worth the money - Worked good
Review: Longer than the regular radiator - It functions well as a radiator, but be warned that it is longer than the regular 420mm radiator that isn't x-flow. I had to upend my entire water loop to barely make enough room for this in my system. I use a NZXT H9 flow and this radiator does NOT fit in the front where 420mm radiators are supposed to fit.
