How to ramp up radiator fans when either CPU or GPU temperature raises ?

[Xoughy]

Hello,

My radiator fans do both jobs: cooling the CPU, and push airflow inside the case for GPU. Is there a way to ramp up the fans when either CPU or GPU temperature raises ? Like using a combination sensor that reports the maximum of the two temperatures ? Do I need some iCUE plugins ?

Unforutunately there is no way to have the fans ramp up based on both CPU and GPU temp at the same time.

No, you can only choose one temperature control variable and cpu temp is never a good choice. You should be using coolant temp for normal purposes. Coolant temp will also increase with ambient case temp. 
 

However, if you are looking for maximum airflow when gaming your best option is to set a fixed fan speed at a level acceptable to you. That gets the most airflow into the case while still doing the other jobs. You don’t need the fans to be reactionary to cpu activity. You can set this up as a separate CUE profile and toggle to it before starting or as a specific fan profile that can be activated in any profile.

Thank you, that is dissapointing to hear. Do you think Corsair will add such a feature to iCUE ?

 

According to the iCUE H170i brochure, the radiator fans should be mounted as air intakes to maximize cooling capacity. It already implies the other fans should be exhaust. Why do you think coolant temp will increase with case temperature when GPU is heating up ?

Because the case ambient temperature will increase along with sustained GPU output. While the coolant temp is less affected on front intake vs top exhaust, it still is affected. Regardless, setting a fixed speed seems to be the best solution for your needs.

Well ... not only the case ambient temperature will go up, so will the room ambient temperature. And when your radiator is configured as intake and the temperature of the intake air increases ...
