I installed 6 (total) fans on the included controller. I have three daisy chained on channel 3, and 3 daisy chained on channel 5. My motherboard does not have 3 pin RGP header. So, I'm trying to use the included remote control to control the fans. However, I can't seem to get the remote to work. I can see that the infrared indicator light comes on when I push a button but nothing happens. Which end of the controller is the IR receiver located? What am I doing wrong?
