Maximus V Formula CPU/CPU OPT FAN header

I changed over to a CM Seidon water cooler. I put the pump on CPU header and the fans on a y adapter on the opt fan header. I turned all the headers to turbo mode but the max rpm or the fans is still only hitting 12xx rpm but rated for 2400 rpm. It's not maxing out on turbo settings. Any ideas to kick these puppies up higher?

you could try installing just the fan expert part of the asus utilities, worked for me

Turn fan control off, that'll run them at full power.

I'd like to also ask, how does this kit ask you to power the pump and fans? My Thermaltake Extreme has the pump getting power from the CPU fan header, and the fans hooking into the pump. You want the pump to be at 100% all the time, I'd also say get an adapter to hook the pump into a 4-pin molex for full speed-operation no matter what, then hook both fans into the CPU fan headers and let the motherboard manage fan speed dependent on CPU temp.

The pump has no plugs. The instructions are to hook pump to 3pin power header and the fans are 4 pin with y cable to be plugged into motherboard header.

Thank you both for the replies 🙂 ill turn control off an try it hen I get home.

Honestly, I'd go the route of hooking the pump into a 4-pin molex with adapter (if you have one?), then, hook each of the two fans into the cpu_fan and cpu_opt fan headers individually without the y-splitter. Leave fan control on if you do it that way, and then adjust the fans as you see fit (cause I'm guessing those fans running full speed will be mighty loud, moreso than you'd want idling for sure)
