Lightroom Classic 14.3 - CPU started overheating on import

Hi, since upgrading to Lightroom 14.3 i have found that my CPU is overheating on imports of more than 200 images. These are Nikon RAW files from a D500 and D850 . Has anyone else experienced similar?

As part of the import i apply lens corrections automatically. I have found that that after about 200 images the CPU goes beyond 100C and shuts down to protect itself. This has never happened before.

PC specs: Windows 10 Pro, 22H2. AMD Ryzen 5 2600X, GeForce GT 1030, 16GB RAM, over 300 GB free on SSD system drive.

Yes i know it is an old PC and my plan is to downgrade to Windows 11 later this year. But I am trying to squeeze the last amount of use from the present box until it is repurposed as Ubuntu server

I would just to know if anyone else has seen a similar phenomenon since 14.3? I plan to stop the automatic application of lens corrections to see if that helps. Otherwise I will have to accelerate my plans to replace this PC.

Many thanks in advance for any help

You talk about the fans working, but are those the case fans? How about your CPU Cooler fan? (assuming not water cooled)

Also, the CPU overheating could be the CPU cooler full of dust bunnies, but could also be the GPU fans (some actions in LrC are handed off to the GPU)

Also, note that you are having this during Import. Not one of the areas of LrC workflow where LrC may be expected to work hard. That is, unless something is occurring with presets, or some auto sync. LrC is a known resource hog, it makes advanced games look like pikes. But during Import??? Thinking computer issue.

Something to try. Instead of getting those images into your computer's hard drive via LrC Import/Copy, copy them from your source (SD card, etc) to your computer using Windows File Explorer. Pay attention to CPU temps (probably fine, but...) Then bring up LrC and Import via Add, with minimal preview creation, and no presets, paying attention to CPU temps. Then select all the imported photos and batch apply the lens correction and any other presets desired. All the time watching the CPU temps to see when the rise occurs.

Your computer's cooling system is not functioning properly. There are some things you can do to try to fix this, including opening the case and vaccuuming out dust, and making sure that all fans are running. If it is a laptop, then make sure the vents in the case are free of dust and that the vents are not blocked by furniture or walls. Also if it is a laptopn, consider purchasing a laptop cooling device.

Thanks but the tool I am using to monitor CPU temperature in real time is telling me that the fans are spinning fine. The fact that this overheating issue exactly correcponds to the upgrade to 14.3 makes me think that the software is thrashing te CPU more than earlier versions. But it will all become moot when I replace the PC later this year

You earlier told us the CPU temp goes over 100°C and then the computer shuts down. How is that "fans are spinning fine"? And as I said, there are other issues that are unrelated to fans that you need to check.

Your symptoms are classic overheating caused by cooling system failure.
