Help please: GPU 'sensor' not working from 'cold boot'

[Nitefly]

Hi all.

My computer is having problems detecting the temperature of my GPU 5090 (Aorus Master) - specifically booting from 'shut down'.

See the below image. MSI afterburner and Fan Control each report the temperature 'static' at 37 degrees. It doesn't budge. Meanwhile, HW info is reporting a fluctuating, higher temperature that broadly corresponds with expected temperature when idle etc. Clearly, HW info is displaying the correct info.

Weirdly, the problem goes away when restarting the computer. See below - after a restart, all programmes are reporting the correct (fluctuating) temperature.

I have tried a clean install of Nvidia drivers, using DDU / windows safe mode, yet still the problem persists.

- any ideas what is going on here?

As an aside, this is the only 5090 I've had this problem with... which doesn't bode well... but at least it's capable of reporting it correctly so I would have thought this is a software issue.

Thanks all.

I think it’s a bug with the Aorus master 5090 bios as I have the same issue. Whenever I select the stats to display on the GPU lcd they all work except the temperature which is fixed at 35 degrees for me.

Ah - interesting. Does it sort itself out on a restart? Worth giving it a go as at least then we'll know we're in the same boat

Yeah a restart fixes it for me but then occasionally it will stop displaying it correctly which makes me think it’s the bios

I’ve just turned it off and only display the gpu power draw now

Noted, thanks.

It bothers me because I usually set my case fans (via Fan Control) to go up and down based on CPU + GPU temps. So they normally ramp up based on CPU, but when the GPU gets toasty they also ramp up even if the CPU is cool.

Really quite annoying tbh.
