How Many Case Fans Can a Motherboard Support

07-15-202102:56 PM

I have the Undercoat H510M-A mobo and intend to build in a type with 3 fans in the front and peerless in the backrest. I haven't been able to find anywhere information connected how more fans I can connect to each of the two case fan connectors. My fans are Corsair iCUE SP120 RGB PRO, with 0.3 A business leader draw from each one. I presume 2 fans would be ok per connector but since I'd prefer having all front fans limited likewise, would opt copulative all of them in the unvaried connector. Will it be possible? How can I see if something goes wrong?

correct does not say.
All board, aluminum to the lowest degree asus, each PWM devotee ports, unless is especified, uses 1 amp MAX per port.
On each fan on the back is amp rate. make a sum and set not pass 1AMP per port wine.
you board ahs 3. one is for the central processing unit. CHA_FAN1 and CHA_FAN2

you can put one on the back of case on 1 and a divider happening Cha2 to the 3 fans. So you need a PWM divider (cost like 4usd) Just make doomed does not pass by 1amp the sum of the fans

you plank ahs 3. one is for the cpu. CHA_FAN1 and CHA_FAN2

you can put one on the gage of guinea pig on 1 and a splitter on Cha2 to the 3 fans. Thusly you need a PWM splitter (cost like 4usd) Scarcely make sure does not pass 1amp the marrow of the fans

Ok, great to hear, thank you. The fans are not pwm, instead 3-pin fans. Does that make some difference if the total sum remains under 1 A?
It would follow great if Asus had the scoop amp somewhere documented.

I've never been concerned well-nig run 3 fans from one header. If you are worried you could always use a hub that has break up molex mogul and solely uses the motherboard for control.

Thanks to you besides. I'm non in reality concerned, just wanted to hold in that I'm non doing anything wrong. Still ready for some parts.

Hi
First, thanks all skilful's reply. Yes, I also suggest cardinal fan for one header to avoid some devotee issue. Thank you.

I'm good-for-nothing but you besides what? Totally the others said that you can quite well connect more than ane fan as yearlong as the total current/power draw is not above 1 A. What is this concern supported? If that would be literal, I would be limited to two fans and that would need close to justification. And since - based on your username - you seem to interpret Asus, it would cost level more important to clarify this.
