very high CPU temperature during noise reduction with lightroom 14.2

[Gérard26300594ntv5]

Hello,

My CPU temperature easily rises to 95°C and then cools down again thanks to the fan. When I batch process 10, 20, or 40 photos, the same thing happens when exporting these photos to jpg files, and the process slows down considerably.

Hardware acceleration is enabled in both Lightroom and Photoshop. I have the latest NVIDIA graphics driver 572.83, completely cleaned of all unnecessary items using NVCleanstall.

I should also point out that I have an HP Omen PC with an i7 12700, and I know it's not as good in terms of cooling performance as a PC that has been rebuilt (my CPU fan is 92 mm, meh). But this problem is new, so is this the beginning of a technical problem for me, or is it a bug in Lightroom version 14.2? I would be very grateful to know if I'm alone in this situation or if others have already encountered this problem.

Have a good evening and a good day everyone, and thank you for your feedback.

…we're seeing LRC causing massive overheating (to a point where computers shut down from overtemp) on brand new laptops.  Intel Ultra 9 level CPU's and 4070 and 5070 RTX GPU's.  All Asus computeres…

A properly designed hardware system should never shut down from overheating because of consumer applications. What is supposed to happen is that if temperature starts to exceed rated limits, the hardware itself — independent of and overriding anything the OS or any application is doing — should be taking built-in steps to reduce temperature. The first step should be to max the cooling fans, the second should be to throttle back all processors (CPU, GPU, NPU, media engine, etc.) until temperature falls to an acceptable level.

In other words, no end user application should be able to directly cause overheating that shuts down the computer. The OS and the hardware should be intervening at lower levels. (Software causing unexpected shutdown could happen if a programmer was addressing the hardware directly.)

I know how to max out the internal temperature and fan speeds of my MacBook Pro by running some specific types of tasks in several different Adobe applications including Lightroom Classic, but the laptop doesn’t shut down because of it.

Bonjour tout le monde,

Dernière mise à jour de Lightroom et possibilité d'activer le GPU pour les aperçus ce que je viens de faire.

Je n'ai pas assez de recul pour confirmer que cela va fonctionner mais a l'air d'être le cas.

J'ai également activé "meilleure efficacité d'alimentation" dans  "système/marche arrêt/mode d'alimentation" de Windows 11: essayez peut-être cela et on pourrait tous mettre un petit feed-back d'ici quelques temps.

Bonne journée à tous.

Hello danielachner,

Have you found a solution? (By updating either the Nvidia driver or Lightroom).

Do you have a brand-name PC like me (HP Omen)? Could the problem be due to insufficient cooling, like mine? (See my previous message.)

I haven't found a solution for my system, so I'm sending you this message (a large i7 12700 engine but a small, insufficient fan for this processor, 92mm, but a 120mm fan is needed).

Thanks for all the feedback.
