Connect Two Fans To One Header

There is only one caveat.

Connect two fans to one header.

Use 75 of header rating to account for inrush current. Basically the block you attach to the cpu has a pump installed this pump head is powered by connecting the sata capable and there s also what looks like a 3 pin female that appears to connect to a fan header the pump is also connected to your motherboard by an internal usb connection the pump head also has two places where you can. It usually works to connect two fans to one header with a splitter cable. When all fans are the same model.

Each fan header is rated for up to 1 amp. I had several fans from older computer builds so i hooked up 6 of them together all red bunched and all black bunched to make a bigger fan that i will us. So again using that typical 140mm 1250 rpm fan 0 14 amps. Then they should run at the same rpm with the same voltage.

But make sure that fan controller can support the needed ampere to run all fans. Use 83 of header rating to account for inrush current 1500 rpm fans. What ever you do. Otherwise it can damage the fan controller.

Gelid solutions pwm y cable connect two pwm fans to one socket the pwm signal input from the mainboard is used to control a series of connected pwm fans for optimal performance in noise and cooling. That s true for either dc fans or pwm. I have a 420 rad in push pull and my logic went like this. 1250 rpm fans.

Do not connect all 3 yellow to one input. It will be a mess.
