Do you have a 2nd PWM port? Like CPU_FAN2 or CPU_OPT...

i was wondering that too...

i have the predator plugged into the CPU_FAN header on the motherboard... and the CPU_FAN header is set on PWM... i just plugged the aforementioned cable just as i unpacked the predator... am i doing it wrong?

Here is what I did / how I am running my setup:
Pump connected on the CPU_OPT header and fan hub on the CPU_FAN header. Pump runs at 25% in idle, but under load the pump goes to 60%. Fans start at 35% and ramp up to 55%
All controlled with SpeedFan. Of course you can set the pump to constant 25% and the pump will still provide propper flow.

Edit: No real fan "curve"! The speed changes at a certain temperatur to directly to the higher speed. Just make sure that the temperature is not a value where the speed would circle around.

Setting it up the default way out of the box is fine too, right? Having the pump connected to the Predator fan hub and connecting it to the CPU_FAN with PWM? It should still get a constant 12v because its PWM?

At what temperature do you have your pump going to 60%?

Well, you should make sure you can controll CPU_FAN and CPU_OPT separately with any tool. Let it be BIOS, AI Suite, FanExpert,... SpeedFan, any.
Yes PWM will provide 12V. PWM will just send a on/off signal on the 4th pin to tell the pump/fan to turn on/off. The longer the "off" signals are, the slower the fan/pump runs.
Pump will run at 25% for any CPU temperature, but will go to 60% at 43°C GPU temp, since the GPU is in my loop as well. 43°C on the GPU is never reached under any CPU load but will be reached and gets higher in games with GPU load. By that I make sure the pump only ramps up in games and not for a 10sec CPU temp peak because of a short load.

My loop goes from pump > CPU > GPU > rad. The reason why I am looking to change the curve is because I can hear the pump/fan ramp up for short loads like when my computer boots up and I don't like that. How do you set it to ramp up based on the GPU?

During loads I am seeing around 60*C for the CPU, so I was thinking of just having it start ramping up during 50*C for CPU.

Before the BIOS is loaded the fans/pump will spin faster. Sorry wink.gif

SpeedFan. Might be the only tool that can do that.

That is a cool CPU, nice! Set the value to a point where the higher temperature will stay constantly higher than your temperature point for the pump. Also a value would be nice that will not be reached under short peak loads.

Haha, this makes sense and I'll give it a try. The 60*C was on the "Standard" setting, so hopefully I'll notice some gains with the custom curve. Thanks for the help! thumb.gif

I think i´m in love not a sound dead silent, can anyone tell me the range of the pump for ex 500rpm to 2000rpm ?

My Predator 360 pump can work between 1250 - 3050rpm.

According to AI SUITE the range you can control is more less 500rpm to 2000rpm, pump and fans are all hooked to the hub then to the cpu main header
