HylianKnight Posted August 31, 2017 Share Posted August 31, 2017 So I just put together a new Ryzen 1700x build using a Gigabyte AX370-Gaming K7 board, Corsair H115i, and the Phanteks Luxe. The Phanteks Luxe comes with a pwm fan controller. My mother board manual shows that all of the fan headers suppor pwm on the 4th pin. I currently have the H115i hooked up to cpu_fan as the instructions say, and the phanteks fan controller hooked up to cpu_opt. unfortunately, all my case fans (hooked up to the fan controller) are running full tilt despite the gigabyte manual saying all fan headers support pwm regulation. I have tried to manually control the case fans but they all run @ 100%. My question is, does the corsair H115i have to be hooked up to cpu_fan? If not, how would you recommend hooking up the H115i and the phanteks fan controller? Any advice would be greatly appreciated. Link to comment Share on other sites More sharing options...
Corsair Blake Posted August 31, 2017 Share Posted August 31, 2017 Plug your H115i straight into "CPU_FAN" and set it to PWM 100% within the BIOS. Enter BIOS by pressing the DELETE key and heading over to FAN CONTROL. You should see the settings to change the "FAN/PUMP CONTROL MODE" over to PWM and leave it at 100%. As far as your fans, we do not support your case and their included PWM fan splitter, so you'll have to get the support from them. If you have any other questions about our products, please let us know! Link to comment Share on other sites More sharing options...
