@W-L: I tried what you suggested, but sadly even in advanced settings I can only choose between DC/PWM modes and set the percentage of fan speed depending on different temp levels. So I can only trust that it's 12V since most(all?) cpu fan headers provide 12V as far as I know. Fractal customer support guy said that the voltage as low as 9V is fine too though. @For Science!: watercooler itself doesn't have any fan headers, both fans are connected directly to motherboard. Fans are not the problem, pump is - according to the manual using pump at too low voltage will result in a fiery explosion. I hope to avoid that.

@W-L: thank you for your kind reply! Sadly there doesn't seem to be an option in my mobo's BIOS settings to set any specific voltage to a fan. The closest thing I could do to what you advised was to manually set up a DC mode and set it to 100% fan speed regardless of temps, so I hope it does exactly that. I can't hear that darn pump working at all, but CPU temp is at 32 Celsius, so...

Hello everyone! Please help, I'll try to keep this short. My mobo Asus Z97i PLUS has three fan connectors: one cpu_fan 4-pin connector two fan_chassis 4-pin connectors specifically mentioned in the manual to be both DC or PWM relevant instruction manual page I bought a Fractal Design Kelvin T12 watercooler that has: two PWM fans, both with 4-pin cables one DC pump with a 3-pin cable Manual says that the pump MUST have a steady 12V voltage, otherwise there's a risk of damage. I initially connected the pump to a cpu_fan and have been told that it's a big mistake. How do I connect it properly? Please help, I'm a total dumbass when it comes to this stuff.
