Anyway, I went into Fan Xpert and hit the Benchmark button that's supposed to create the fan profile and it went through a cycle of 100 percent down to zero fan speed.Īfter this the fans all stopped working. However, I decided to mess around with Asus's AI Suite III and their 'Fan Xpert' to try to create a more optimized fan profile so that all of the case fans on that fan hub would run even quieter and also run faster when needed (I don't know why I bothered because it was already almost silent and under full load my GTX 780 stayed at 68C max). The fans on the hub were all quiet and running at probably 50-70 percent.

I'm not sure how I originally set things up, but it was fine. The SP140 is plugged into the first socket on the fan hub because the first fan is the one that's controlled by a fan profile and then all of the other fans on the hub just run at the same speed/duty cycle as the first one. That's what all of the fans except for the two on the H100i radiator are plugged into. The Phanteks Enthoo Primo case has a built in fan hub that you plug into the CPU OPT header on the motherboard. Only the two fans plugged into the CPU fan header are working (they go to a Corsair H100i).īefore I go further, the relative hardware is:Ģ 120mm Corsair SP120's on H100i radiator I'm using a Phanteks Enthoo Primo case with some stock Phantek's fans and some Corsair SP120/SP140 fans, and I somehow screwed something up trying to create a more optimized fan profile for them.
