1250 to 3000 RPM is about right for the 6 W DDC used in the Predator 240/360.

You sure that's PWM control over the pump itself?

Yes the cpu header is pwm the thing is AI suite see´s one fan then testes the range...but in this case, fans and pump are all connected to the EK HUB so i dont really know how reliable or what is actually happening, the only way to test it is to remove all the fan and test only the pump

The splitter is reporting RPM of the device connected to the first header, which is a fan in your case. So AI Suite in your case is detecting the RPM range of the F4-120ER fans, and not the pump.

Ok, but still when i set the fans into turbo mode i hear the pump cycling water more aggressive, my logic is if ASUS testes the range an see´s one "fan" that range should be 1250 the minimum of the pump. still confused thumb.gif

That's because it is increasing the PWM duty cycle to increase the fan speed, and this increased PWM signal is fed to all fans and pump via the splitter.

geggeg is right. You have your fans and pump connected to the same fan hub. That is a PWM hub!
The fans and pump will all get the same PWM signal, which makes them increase their speed on a similar base. But the PWM signal will only adress a % of speed to them.
So a 50% speed signal will work differently on a fan with a range between 500-2000rpm and a pump with a range between 1250-3050rpm.
Also, the fan hub can only report ONE signal back the motherboard, which is the fan/pump connected to the fan1 port of the splitter.

So what is the effective range on the Predator 360 pump and fans?
post #5678 of 7180
Look at my charts above. 1250-3000 RPM for the pump and ~450-2200 +/- 100 RPM for the fan.
post #5679 of 7180
so... hwinfo64 reports like 900rpm on the cpu_fan header... i assume that's the speed of the fan and the pump...

Just one of these! A single fan header can only report the rpm signal of one device! Guess it is the fan wink.gif
