Please Help! Lian Li SL120 fans not spinning?

BradoKara · 19 Dec 2020 at 18:23

Hey,

Just installed 3 SL120 in my O11 case in a series.
None are spinning.
RGB and software is working fine and software is detecting the fans.
Checked all connections on the mother board, tried all cha-fan/WP slots...so now at a bit of a loss.
Can't see them connected in the bios like the CPU is showing?
Any suggestions.
Am I just being stupid and missed something simple

Mother board - Asus Prime Z490-A

Which header did you plug the fans into on your motherboard?

CHA_FAN2 currently

CHA_FAN1 is inaccessible at the moment.

Have tried it in all of the Fan/Pump headers.

Did you connect the fans to the control box?

Yes

Honestly can't work out where I have gone wrong unless I have a faulty cable with Lian Li kit

They look great just have no spin which really defeats the point.

might be a faulty control box

Hakanese · 19 Dec 2020 at 19:09

do you have the power plugged into the control box?

Ok so the 2 cables from the fans are connected to the control box, then you have the sata power, and 2 more cables from the control box going to the motherboard, one is a 3pin argb, and the other splits into 2 more connectors, one of which goes to a fan header, the other to an internal usb socket

Ok so maybe you have found my problem.

I'll check this out :rolleyes:

Sometimes someone else and other eyes make all the difference.

Nope all pluged in. Just got the splitter left but don't require that. For a moment thought I had missed something about that.

tried different slot on the control box? and have you tried with just 1 fan at a time?

Thanks will see if that solves it in the morning.
I can hope

Asked a friend he says you can just plug the pwm connector directly to the mobo just to have them up and running, leave the controller connected to argb and power. And control the fans for the time being with Asus Ai Suite 3.
It's a real ballache
