I have a Lenovo P16v mobile work station. In short the CPU gets very hot (localized on highly loaded cores).

Is the below a worry? Often the CPU will have cores at 90C+ and the fan aren't fully ramped.

Note that the Motherboard has been swapped by a technician, so the thermal paste would have been replaced as part of that.

It'll max at 100 according to Intel... another site I read someone was querying it on their desktop 13900K, and response was its quite normal when under load.

So what's running when you check it ?

Was it doing this before the board was replaced? Would not be the first time I've seen their service techs poorly apply thermal grease.

Under load, with a i9 x900, I'd say its normal. Even with a lower TDP, an i7 running light gaming pushed those temp right up.
Modern CPU these days are very much safe, it automatically throttles down nowhere near a failure.

I'd still check if the laptop comes with a "overclocking" utility and see if the fan settings / curve is set incorrectly

Consider applying a slight undervolt if possible!

All the 13900{x} run hot.

Get better cooling.. and lower the power a little bit.

For that image I ran a web based cpu stress test (single core).

But cores bouncing off 100c happens anything I do anything CPU intensive.

Looked into temps because I couldn't see any other bottlenecks to CPU proformance.

I didn't check temps prior sadly

Thanks, Yeah, the temp shoots up to 100c on load, then clock speed etc dial back. I have never seen anything more than 100.

It's a mobile workstation, so no overclocking utility included.

Kinda reluctant. Brand new work laptop with a 3 year warranty. And for the application I need stability over performance.

It's a laptop, so limited what I can do with regard's to better cooling. Limited options:

Swap whatever thermal paste the tech used for really high end stuff
Put it on a cooling pad
Get some kind of software to run the fans harder.

Compared to my other laptops the exhaust air seems cooler, so wondering if the heat may be having issues getting from the CPU to the cooler?

Don't think I should be playing around with undervolting on an expansive laptop that is under warranty (and not mine).

Is the variation between core temps normal. Many efficiency cores at 55c, while a performance core is at the 100c limit?

I'm doing lots of computationally heavy stuff at the moment. (I have an AutoCAD plug in that auto generates layouts for me).

Each run takes several minutes, and while the CPU sits in the 32 - 38W range (actually noticeable higher now we are in the evening and the room is a little cooler).

Is this acceptable cooling performance for a mobile workstation with a 45W power profile?

Any Intels do just run hot especially the i9s but what percentage are your fans running at? I'd consider getting FanControl (It's open source on GitHub) Assuming your fans have controllers, then you can control the percentage and see how they're running.

In my opinion, this is better than Mobo control, this software is more in-depth and you can control a lot more.

Undervolting is safe, if done in small incriments. In most cases, it will lower your temps and wont effect performance and may even increase performance (less thermal throttling and less power draw)

Sadly FanControl doesn't seen to detect my fans.

Have ordered some Honeywell PTM7950 Phase change silicon pad sheet. Apparently it is nearly as good as liquid metal, but without the conductivity risk.

Have read up on undervolting. I see the main risk is instability. Could well be worth a crack.

is it a single core load in that last picture?

looking at the load on the core next to it, considering its about the same and the temp is 35deg different there could be something wrong

But i9's run notoriously hot in desktops, and that's only going to get exaggerated by putting one into a laptop.
