Thank you for your answer :)

Did you tried to undervolt your CPU ?
What is the average CPU temp during gaming cession ? I guess (and hope :D) it is not at 100C
because the Processor wants to hit 5GHz any undervolting only goes towards more headroom for higher Hz.

AAA games on ultra whilst streaming on obs (using the processor streaming rather than the nvidia one because it was better imo) the processor goes between 90-100C with it varying between 3900-4200MHz on all cores.

While not streaming its around 4200-4700Mhz on all cores but still at 100C

Older games have better temps which are around the 70-80 region. but the processor is barely hitting 20% usage and the cores remaining at 5GHz.

The only way to get the temps down is to lower the multiplier on the CPU for 8 core workloads which defeat the purpose of having a 9900k. The candle that burns twice as bright burns half as long. The core is more likely to current throttle rather than thermal throttle in most instances from my own observations once an undervolt is applied.

To be honest I really probably didn't need the 9900k but you could say this was a bit like buying a sports car to drive to work.

Compared to the Alienware 51m this is a better buy IMO, even though the Alienware has better current draw because two power bricks, it runs so hot the failure rate is worse.

I use my laptop for gaming for a few hours every day after work. I expect the processor will be obsolete before it fails. I doubt there are much object studies on running temps and fail rate other than common sense observations on deformation effects on silicon and metal over time.

Eeek

The cpu on the other hand (9900k) can go all the way up to 100C at full load. Cant comment on the 8700 but I can confirm this laptop is good at belting the heat out the back when in hair dryer mode.

If the CPU goes to 100 degrees, I guess it's not quite good enough in terms of getting rid of the heat :S

I don;'t think those temps are good for the lifespan of the system at all.

I'll invite you to the funeral hahaha,

I wouldn't fault the laptop when it's running a processor that's running way over spec to what it was originally designed for.

I reckon the 8700 might be fine since its a bit more sensible.

We should start sweepstakes with predictions on how long the i9 octanes will live for.

place your bets

I'd probably complain to PCS tbh, it's not okay for the CPU to hit 100 degrees - especially just while gaming.

So you think this is a sign of something wrong?

this is me playing on 1080p Ultra, whilst also streaming using obs.

The main thing that's wrong is that you appear to be playing Anthem? *cough cough*

Kidding aside the CPU is at 98 degrees at 55% load. And you say it hits 100 too. So it's not a 1-off spike. And it's already dialing down the frequencies from max boost clocks a bit.

I'm not familiar with mobile GPU temps for Turing, but 86 degrees seems warm, especially if the thing's not at max load. I assume there's a shared heatpipe with the CPU which might go some way to explaining, but still, to me it seems the laptop is running hotter than it ought to be.

Also NB:

from the kit guru review==
On the one hand the Core i9-9900K CPU is much more powerful than a typical mobile CPU, but balanced against that we have an enormous chassis that has the space for a substantial cooling system. We were impressed to see the CPU operated at 80 degrees C under sustained load and that the GPU was only slightly warmer at 82 degrees. Both these figures are well within safe operating limits and the CPU, in particular, is running up to ten degrees cooler than we see in some laptops.

oooh i can see what you mean now, I'll contact customer support then
