Really good question....I just swapped motherboard and cpu in my system. When I went back together with it, I swapped the ML Pro fans with ML pro RGB on my radiator. Only had 4 fans hooked up to the commander. Now, I have 5 ML Pro RGB fans, or should I say 4, now that the #1 port is dead. Worst part is, Corsair replaced it for the same thing 6 months ago, and now I'm 4-5 months out of my original warranty.
Think I'm going to go with Aquacomputer 6 lt controller this time. 2.5A per fan header, overcurrent protection and time out, and short circuit protection on fan headers. At least I don"t think I can blow it up.....
BTW 5 fans, one per header, ALL Corsair ML fans.
If a way to fix this exists, I'm all for it.
