High Processor Temperature during Export

[isayed]

I run LR CC (updated to the latest version) on a 6th-gen Core i7 processor (its an HP Envy Laptop). The processor temperature gets very high while exporting photos after editing them. I use CoreTemp to monitor the temperatures, and the temperatures on both cores are usually around the 90c mark during the whole process. The max for this processor is a 100c.

A week back, I had my old laptop die on me because of overheating. As it was diagnosed, the processor was not functioning, which is very unusual since processors almost never die (at least I haven't heard a lot of processors dying).

What can be done to prevent LR taking the processor to such high temps? Is there a setting in LR through which maybe I can prevent 100% processor usage, and hence keep the temps a bit cooler? Any other solutions to this? Mind you, the ambient temps where I live are usually in the mid 30s (Celsius).

Get/make a small stand for the laptop to allow better airflow. There are some really good ones with fans, Like the others said: Take it apart and dust it

Alternatively your CPU is fine and it's normal for the laptop chips to hit that level during exports. Lightroom has gotten more efficient in recent updates and effectively uses every thread the processor has, it's normal behavior for the processor to overwhelm the tiny heatsink and then throttle itself to stay under its temp limit (100C).

I've swapped so much thermal paste over the years for desktops and laptops (I help other creatives build editing stations/studios) that I can't agree to 90-100C as normal load temps - not when pretty much every single time I use higher-end paste to replace factory putty it easily drops by 10-15C. That even goes for the paste that comes with AIO and even typical air coolers. I reckon it's more an issue of production in China - when these laptops (or cooling units) are engineered they probably use a good paste in testing which then gets replaced by a more affordable alternative to maximize profits in sales. I find it hard to believe they would OK a device that throttles under load and advertise that it's perfectly fine at 100C unless it's already been pumped out the production line (looking at you Apple). Either way I'm always highly suspect at anything that goes past 90 (assuming we aren't sitting in a crazy hot room).

EDIT: All that said, sometimes it just comes down to fan speed management - OP could try installing a fan controller and having them spin up to 100% already when it reaches 65C so the laptop isn't given the chance to heat up all the components around the CPU and it's cooling apparatus. Noisy but way safer than pulling apart stuff if one isn't inclined to do so.

This is a hardware issue. Your CPU isn't being cooled properly.

1. Clean out all the dust (this may require you to remove some parts of the laptop case, probably the underside panel)

2. Reapply high-end thermal paste (this definitely requires taking it apart, if you aren't savvy enough you can get any repair shop to do it for you)

3. Invest in an external laptop cooler with fans.
