Are the included Air Cooling components powered by the case ?

Hi guys,

Quick question : I wanna buy a new case, which includes 3 120mm fans.

Problem is : my micro ATX board only has 1 3 male pin connector. Do they draw their power from the already existing case to motherboard connections or do they each require a 3 pin connector ?

Best regards,

Reddox.

The case does not supply power to the fans generally. Some cases do come with controllers, but generally they just include fans which must be plugged in somewhere.

If it were just 2 fans, you can get away with running a splitter like this: SilverStone Technology All Black Sleeved 1-to-2 Sleeved PWM Fan Splitter Cable (CPF01). However, I don't recommend running more than 2 fans per header.

In this case it looks like your best bet would be to run a fan hub, something like this: SilverStone PWM Fan Hub System Cables, Black (CPF04). This would allow you to power the fans from your PSU, via a SATA connection, but still send the fans a PWM signal so they will speed up and slow down accordingly.

You could always buy a manual fan controller to if you wish.
