View Full Version : PWM Problem - can anyone help?

10-19-2014, 08:39 AM
I have a Phantek fan hub, 3 Phantek PWM fans and I am using a Asrock Extreme 6 Z97.

Basically, I cannot get it to work. I can get a single fan to work if I plug it directly into the CPU fan header, though. I've set it up to run at 50% speed and it runs at 50%.

The moment I route the fans through the fan header they all run on 100% irrespective of the BIOS settings (which work with a single fan). Can anyone help? Seems very odd to me - something to do with the PWM part of the hub? I am making sure there is at least one fan going into fan1 on the hub (FYI).

Any help much appreciated!
