Lightroom Classic immediately causes fan to run

[rocketman1222]

When I start Lightroom Classic (13.2, build 202402141005) on my Windows 11 (23H2) laptop (Ryzen 7 5825U, 16GB RAM), it immediately causes the fan to start blowing and it never quits until I close the application.  In the Task Manager, Lightroom itself shows up as using almost no CPU, but a "System" task is generated as soon as LR starts, and remains until it is closed:

I have tried, I think, most of the usual tricks:

- I have paused all tasks, including face detection

- I have disabled all plugins

- I have played with GPU acceleration settings

- I have let LR idle overnight to see if tasks needed finishing

- I have done a full reinstall, removing preferences on the uninstall

That last one is a huge pain and was a last resort, and it still didn't fix the issue.

I have been using LR "Classic"/Desktop since before it was a subscription, and while I don't know exactly when this started, it's fairly recent...6 months?  There has been an update to the program since this began...I was hoping that an automatic update would cure the problem the same way it started, but nope.

Does anyone have any ideas on this?  I can't leave LR open on this machine because it sounds like the laptop is overheating, even though the CPU is only at 25%.  It starts almost immediately with the application, and quits within about 30 seconds of closing it.  I'm growing reluctant to use LR at all because the noise is so irritating.  Help!

Fans run because it is too hot inside the case, and if they don't run, your computer will overheat and shut down. Why is it getting too hot? Some breakdown of the cooling system inside the computer, such as build-up of dust blocking air flow vents, other items (furniture, wall) blocking airflow vents, and so on. Vaccuum out the air flow vents. If you can open the case, do that and vacuum dust out of there as well. There's plenty of advice on the internet, such as: https://techreviewadvisor.com/laptop-fan-constantly-running/ and also https://www.dpreview.com/forums/post/65523199

Are you using the latest GPU driver available?

Bingo!  Thank you for this suggestion.

There was indeed a graphics driver update available, which I was able to install easily from the NVIDIA app in the system tray.  Now when I start Lightroom, there isn't that phantom "System" process and LR properly indicates its own usage in the list.  And when the application is idle, CPU usage is minimal, not that constant 25-30% that I was seeing before.  Thanks again!

OK, I wasn't aware you have an additional dedicated GPU.

Anyhow, it's fixed, and thanks for posting back and letting us know 🙂
