While we're on this subject I would just like to warn everyone to AVOID buying H100i until Corsair have released a fix for the totally-screwed voltage regulation on the fan controller. CorsairGeorge and RAMGuy (Corsair reps) have claimed that it can and will be fixed in an upcoming firmware update. I don't know how the hell a firmware update can fix hardware issues, but they said they can fix it so *shrug*.
No update from Corsair yet, but me (and a million others) are keeping a close eye on it. Ta-ta.
