CPU Fan in Water Pump Header?

[ishtiaq199mi]

Hi, I am using Asus B150 Pro Gaming Aura Motherboard. I have Cooler Master Hyper 212x CPU Cooler. I attached an extra fan with the cooler for push pull. My mobo has 1 cpu fan header and 1 water pump header. I connect the 2nd fan into the water pump header. It runs absolutely fine. But can it be a problem in the future? Or, is it bad for the health of mobo or the fan?

The W_PUMP header is similar to the other fan headers but, by default, runs at Full Speed (you can change the speed via Asus BIOS though). The CPU_FAN, by default, runs at variable Q-Fan Controlled Speed (you can also change this).

Personally, I would just either 1) get a PWM Y-Splitter and connect the 2x PWM fans of the Hyper 212x to the CPU_FAN header; or 2) Connect it as it is (1 fan in CPU_FAN and 1 fan at W_PUMP) but would adjust the fan curve/speed on both headers identically so both fans would be in synch (I am assuming both fans are the same).

Health-wise as you asked, there's no problem with the motherboard. The fan that is running in 100% full speed *might* suffer more though (compared to the slower spinning fans).
