Malcolm900 Posted August 12, 2013 Share Posted August 12, 2013 I have 5 Cooling Nodes 1 lighting node connected to a link Commander. I have 26 Corsair SP120 PWM Quiet Edition Fans 25 are connected to 5 cooling nodes and one fan is connected to my CPU PWM header on my motherboard. One of my Corsair SP120 PWM quiet editions fans is making a buzzing noise when I run this below maximum speed. I have been setting the fans to 500rpm using the fixed RPM setting. I am using Corsair link Software. 2.3.4816 Commander firmware 2.0.6 Cooling node firmware 1.2.11 on all 5 cooling nodes I am using lighting node firmware 1.1.9 The cooling nodes are connected to channels 1-5 on the commander and the lighting node to channel 6. I believe the buzzing noise maybe caused by the cooling node the fan is connected to. I have so far tried different firmware 1.2.5 on the cooling nodes. Any suggestions on where to go next?
