zephead99 Posted March 30, 2013 Share Posted March 30, 2013 I currently have my h100i in a push/pull config with the PWM fans all on the block fan controller and I started hearing an odd tapping sound. I thought it was the radiator at first but some testing proved it to be the fan connected to the #2 spot. The tapping actually follows to any fan connected to that spot. I currently have to run that single fan at a minimum of ~1200rpm to make it stop which eliminates quiet mode from use. The sound almost sounds like the sound the PWM fans making as they're about to increase rpms but corsair link shows the rpms holding. Anyone experience this sort of thing with PWM fans before?

Corsair Employees RAM GUY Posted April 1, 2013 Corsair Employees Share Posted April 1, 2013 What FW are you using for the cooler? I might have seen this before with my personal system, but I think I was using 1.04 FW with PWM fans and got it corrected by flashing to 1.05, Link to comment Share on other sites More sharing options...
