Why'd ya go 240 vs. the 360? I mean, I'm happy with my 240.. but still.. if I could have popped a 360 in there, Id have a 360 in there (and am tempted to modify the one I have to put a 2nd radiator inline so I can run one at the top of the case as well.. to get 360 worth of cooling out of it.
Why don't you go for CorsairHD Series RGB fans? That way you can choose whatever color you want.
I have them in one of my machines, one of them is used the other side of an R9 Fury X Radiator.
They come with a wired remote that you can run underneath / outside your case, or since you have an Axi series PSU - Corsair Link.
I am happy to say that it’s been a year and a half and this machine is still a beast. Even though we are on the 3rd gen of Threadripper CPUs, I am still very much enjoying the power while I stream, make music, play games, develop software and every day use.
