Hi. First time poster! Having a strange problem with my new Maximus VII Hero MB and my case fans.
I've got four Cooler Master Jetflo 120 red LED PWM fans around my case. They are all connected to the CHA_FAN 1 to 4 connectors on the MB. I've set the fans to PWM in the BIOS.
The fans connected to 1, 2 and 3 behave as I expect - the LEDs stay on continually and the fans turn on and speed up as needed.
However, the fan connected to CHA_FAN4 behaves like it is in DC mode - the fan LEDs get brighter and dimmer depending on the fan speed, and it's speed can not be set as slow as the others.
I have swapped the connectors around so I know I don't have a faulty fan. Have also tried resetting the CMOS and updating the BIOS.
I'm inclined to think there is a problem with the CHA_FAN4 PWM driver but just wondered if anyone had any suggestions?
Thanks.
