Hi, so I have a MSI B350 Tomahawk mobo which has 1 CPU_FAN, 1 PUMP_FAN, and 4 SYS_FAN. I was wondering if I could plug a normal case fan into the PUMP_FAN and if I did what would happen? I'm trying to set up 5 case fans and so I only have the PUMP_FAN slot left. Four of my fans are plugged into the respected slots and the CPU fan is also plugged into where it belongs. So all I have left is one fan and one PUMP_FAN slot. Please help and THANK YOU! =]

Yes, you can safely connect a case fan to your motherboard's PUMP_FAN1 header. It works (by default) as a PWM fan header. If you plug a non-PWM fan on that header, it will run 100%, providing constant +12V. If you have a PWM fan plugged in, it can change speed based on PWM signal (changing current on constant +12V).

You can change the header's function if PWM or DC in BIOS.

DC headers provide variable voltage to non-PWM fans so that you can change the fan speed by decreasing the voltage.

Oh okay thank you so much! Oh any idea if corsair HD120 RGB are PWM fans or non-PWM?
