How many fans can 1 fan header handle ?

[Tai Tran]

I will have at least 10 fans in my build. I will buy some fan hubs to connect them to the mobo but idk which fan hub should I buy because idk how many fans can 1 header handle. I will be using the corsair sp120.

Its more a question of how much wattage can be drawn from that header. The fan controller your buying will tell you how much wattage each channel (ie, control knob) can deliver. The fan will tell you its power draw, leave enough wattage for an extra fan as when they first spin up they can spike above their rated draw.

Connect just one fan to one header. Motherboard fan headers are not designed to power multiple fans.

For 10 fans, i'd recommend buying a fan controller that's directly powered from the PSU. If you're getting the performance edition, every fan will draw 12x0.18A = 2.16W so we're talking 21W of fan power. I'm asking myself what kind of a beast system will need such airflow.
