Arithean Posted October 14, 2018 Share Posted October 14, 2018 (edited) Why does my CPU fan not use the temperature listed (temperate of the liquid?) and instead uses my CPU's temperature? I was controlling my CPU fan through the BIOS, but now that my fan is included in iCUE (and I can't put a delay for when the fans should rev up), I'm getting random fan RPM spikes. Could there be an option to use the liquid's temperature or could there be an option to add a delay before the fans rev up? https://imgur.com/a/aArDQZF To explain the image, I'm alt tabbing back into a game, causing the CPU temp to rise to about 55, triggering the cooler fans to rev up. I may just have to create a custom fan curve using the CPU's temperature. Edited October 14, 2018 by Arithean Link to comment Share on other sites More sharing options...
DevBiker Posted October 14, 2018 Share Posted October 14, 2018 First, your image doesn't appear. Second, are you using a Commander Pro? What kind of radiator? How are the fans connected? There's a lot of relevant and needed information missing from your post before anyone can take a shot at helping out. Link to comment Share on other sites More sharing options...
Arithean Posted October 14, 2018 Author Share Posted October 14, 2018 (edited) Not sure if you saw the updated image link. It shows that i have an H80i GT. The fans are connected directly to the CPU fan port on the motherboard. I do not have a commander pro. Hope that clears things up.

c-attack Posted October 14, 2018 Share Posted October 14, 2018 You uploaded image is just a snip of the current coolant temperature and fan/pump speeds. That is not the configuration screen. Select the H80i GT tab in iCUE. Then Performance. That will give you access to the three preset curves (which always run off coolant temp), but also the "+" symbol will create a new cooling mode to make your own curve. Above the graph for the custom curve will be the control variable choice. For the moment, you need to stop using the BIOS to try and alter the fan and pump speeds. You are not controlling the fans. You are cutting voltage to the entire unit and this is having an adverse affect on your pump and fans in terms of minimum speed and it won't help with longevity either. Set your Q-Fan header to Full Speed/100% or Disabled, depending on whether you are in the EZ or Advanced BIOS. After that, iCUE/Link does all the speed control.

Arithean Posted October 14, 2018 Author Share Posted October 14, 2018 After disabling Q-fan, iCUE now uses the coolant's temp instead of the CPU temp. Thanks for the help, c-attack! Link to comment Share on other sites More sharing options...
