I have an ASUS H97 Plus mobo, cooled with the Cooler Master Masterliquid 120.
As far as I understand, PWM is superior for longevity and if you have 4 pins, you should be using PWM.
In the bios, (my pump is plugged into Chasis 1 slot) when I swap from DC to PWM, the LED gets significantly brighter and the liquid starts making a flowing/bubbling noise. However, when it's on DC, the pump is silent.
I also have 3 chasis fans (all connected to Chasis 2 slot):
2x Corsair SP120 PWM (1 with LED and 1 without)
1x NZXT stock fan that comes with the NZXT S340 case
When I switch from DC to PWM, the LED also becomes significantly brighter and the fans sound like they are running at full speed, despite being able to set a lower fan curve than I am with DC, they still run louder.
(From my mobo, the minimum fan speed for PWM is 20% and the minimum for DC is 60%)
From OpenHardwareMonitor, it says Fans 4, 5 and 6 (I assume those are the 3 case fans) are running at 100%.
Lastly, is it recommended that I leave my pump off till the CPU hits a certain temperature? My GPU (stock air cooled) is turned off till the core hits 40c. Should I do the same with my cpu?
