View Full Version : ASUS Strix Z270F - PWM fan control according to the GPU temperature

Hi all, I am wondering, whether is possible to control speed of GPU fan connecting to some of headers on ASUS Strix Z270F MoBo. I bought MSI GTX1070 SeaHawk card with water cooled GPU and fan on radiator has separate connection. So can Z270F read temperatures from graphic card and then set propper speed via PWM for radiator fan? Thanks for any advice. Now I am controlling fan speed only manually by 5/7/12V switch on my Fractal case. Would be nice to control speed automatically.

hi Kod , welecom ROG fourm

Does GTX1070 SeaHawk need to connect the PWM cable to the Mobo
You can download GPU Tweak II to control PWM function
(I have used Fury reference is possible to control speed of GPU fan)

Thanks for your cordial welcome. Unfortunately MSI 1070 Sea Hawk does have fan on radiator without PWM (only DC control) and need to be connected somewhere (no header on graphic card, so on MoBo). I changed fan on radiator to one with PWM, but it still do not solve my problem, that I cannot control fan speed automaticaly with respect to GPU temperature readings. GPU Tweak II can control only fan on card, which cools VRM only.
