LL120/140 Power Draw

Recommended Posts

I'm planning on a 570x case with the following setup:

 

3x LL120 front intake

2x HD140 front radiator pull

2x LL140 top exhaust

1x LL120 rear radiator push for hybrid GPU

1x ML120 rear radiator pull exhaust

 

Can I route all this through a Commander Pro with PWM splitters? I read the max is 1A limitation per fan header and a 4.5A limitation for the entire unit, but couldn't find any info on the LL fans power draw.

 

Thanks!

Cheers! Thanks for the quick replies.

 

Just an ML classic, since it's between the rad and case on the rear, didn't see the point in RGB...but want good performance to exhaust air since the push fan on it will be a LL.

Asking because there is a difference in the amperage rating. The "Classic" ML-120 is rated for 0.219A.

 

BTW ... the max amperage rating is actually on the fan itself, on a sticker on the back. These are also max ratings ... likely current draw during actual usage may be significantly less.

So use the max rating when you size the connectors,as i'm sure you have seen already, during startup they rev to max RPM (therefore max current) before PWM kicks in. So you will have all fans pulling max current for a brief period each startup/reboot/etc.
