Can I connect 3 Arctic P12 Pro fans to one fan header on my motherboard?
Asked by

I've got a Gigabyte B550M DS3H motherboard, and the specs say that all fan headers can support AIO pumps, pumps, and high-performance fans, delivering up to 2A at 12V (24W total). The Arctic P12 Pro fans I bought draw 0.33A each. This seems to indicate I could technically connect up to 6 fans to one header, but I'm planning to connect only 3 fans, which would total 0.99A. I'm looking for confirmation that it's safe to use a Y splitter to connect these 3 fans to one header without running into issues.

It's a good idea to leave some headroom, so running close to the 2A limit isn't the best. If you're only connecting 3 fans, it should be fine, but keep in mind that it’s safer to have a fan hub for more than a couple of fans. A hub pulls power directly from the PSU and lets you use the header just for PWM control, which can help with fan management.

QuestionAsker: Thanks! I just wanted to confirm it's okay for 3 fans, but I’ll definitely consider a hub if I decide to expand later.
