    Strix 1080Ti - FanConnect 2 headers not working

    Hi everyone,

    I have an ROG Strix GTX1080Ti OC with a Phanteks water block fitted. The card has two "FanConnect 2" 4 pin fan headers on it as most strix cards do. I have just recently connected my two corsair ML140 PWM case fans to these headers to control through GPUTweak 2, however the GPUTweak software doesn't seem to detect them. I'm not seeing the "External Fan Speed" slider.

    The fans don't move, I've tried adjusting the regular fan speed slider and that doesn't affect it either, they just sit there not moving. When I start my PC they spin for a couple of seconds before turning off, and then I can't get them to move again.

    I have the latest version of GPUTweak 2. My system specs are under my username.

    If anyone could help me that would be great.

    Ah never mind, I figured it out. I had to add the external fan speed slider manually by clicking the icon on the top right.
