Default One i145 GPU fan control


The RTX2080 card in this system has one of it's fans replaced by a liquid cooling module. I would like to be be able to control the speed of the other fan, but it appears to ignore any attempt to control it. I have tried with bot MSI Afterburner and with EVGA Precision. The ICUE software only controls the ML140 case fan.

Additional info:
* When monitoring/setting with afterburner, the speed percentage gets set, but the speed rpm is unaffected.
* When under load, the GPU fan speed creeps towards 3700RPM. I think this is the card's internal fan curve at work.

Is this a known issue and maybe even on purpose to protect the system? Or is it unintended and is there a fix for it?

Many thanks for thinking along!

Hi Mate,

To shed some light on your question I believe the VRM fan is controlled by a heat sensor tucked into the VRM heatsink so I don't think its controllable in any other way.

Check out Jayz2cents video where he swaps out the 2080ti (i160) for a Titan RTX, he gives a great view of it in this video (9mins onwards).
