Thank you! This is going to be my first custom water cooled build. Corsair has a very nice tool for building a custom system. If I go with the xd5, I can get 2x 360mm radiators and 1x 420mm. According to what Corsair says concerning that configuration, the fans should never even hit full speed even with the loop cooling cpu, gpu and m.2 ssd. We'll see how right they are! Thanks again for the insight!
