Hardware spec:
ThinkPad X1 Yoga 2nd
N1NET33W (1.20 )
Intel(R) Core(TM) i7-7600U CPU @ 2.80GHz
Production date 2017.11
Software:
Distributor ID: Ubuntu
Description: Ubuntu 17.10
Release: 17.10
Codename: artful
Linux 4.13.0-36-generic #40-Ubuntu SMP Fri Feb 16 20:07:48 UTC 2018 x86_64 x86_64 x86_64 GNU/Linux
Bios:
I set both battery and AC to performance in my BIOS settings, the BIOS is up to date.
What is the problem
The problem is that a threshold of CPU temperature is hit quite too early, it happens around 75°C, even though the CPU is allowed to reach up to 100°C. The temperature never goes higher than 85°C. So the CPU power gets throttled so fast.
I don't know if I may have a manufacturer hardware issue regarding inadequate thermal paste, or if it is software related. Before I send it to Lenovo I want to be sure it's not a self-made problem.
Stats
When I run a stress test
stress -c 4 -t 300
the error message happens almost instantly.
i7z gives following output:
Cpu speed from cpuinfo 2903.00Mhz
cpuinfo might be wrong if cpufreq is enabled. To guess correctly try estimating via tsc
Linux's inbuilt cpu_khz code emulated now
True Frequency (without accounting Turbo) 2903 MHz
CPU Multiplier 29x || Bus clock frequency (BCLK) 100.10 MHz

TURBO ENABLED on 2 Cores, Hyper Threading ON
Max Frequency without considering Turbo 3003.10 MHz (100.10 x [30])
Max TURBO Multiplier (if Enabled) with 1/2/3/4 Cores is 39x/39x/39x/39x

As said, it never exceeds the 85 Temp, yet the CPU gets throttled.

But the high-setting probably has no effect.
thermald
So I've played around with thermald then.
This is my adjusted configuration that I've found here:

This makes no real difference, but I can see threshold settings at least (the last lines):

Final thoughts/questions
- Is it possible to set the CPU temperature threshold?
- Is it meant to be set at all or is this BIOS/hardware related?
- May my hardware (thermal paste) be defect?
- Or did I maybe analysed something completely wrong?
Update #1
After diving deeper into this topic and reading several articles regarding Intel's CPU throttling and other posts facing same (or just slight different) issues on other operating systems and kernels, I came to the conclusion that my laptop may be not misbehaving as I thought it would.
Though the kernel-messages are still bizarre, but the reason could be a wrong kernel printk level or whatsoever. I also retrieve those messages when my CPU package temperature is around +52.0°C and CPU frequency just 1200MHz. This just does not make any sense at all.
When testing my laptop with stress-tests I can see the error messages, but in fact the CPUs don't get throttled. If I test 1 core only, I get full turbo boost speed of 3,900MHz. Testing all 4 cores reduces the maximum frequency to ~3,300MHz. Which is the expected behavior.
So I'll just put this issue aside - unless someone here may provide more insides.
Update #2
No changes after updating the system:
No LSB modules are available.
Distributor ID: Ubuntu
Description: Ubuntu 18.04 LTS
Release: 18.04
Codename: bionic

So my final assumption is that the logs are highly likely bogus or that the log-level is mis-configured. Because my laptop just works fine, nor does it get throttled, neither is it overheating.
Still, if anyone has a hunch how this could be fixed, feel free to answer :-)
Update #4

I am still getting the threshold throttling messages.
Update #5

I just found a post that states that this issue is even not fixed with the brand new X1 Extreme 2nd Gen.
For the sake of fellow people who are thinking about buying the notebook I have, here are some issues I am facing besides:
- Touch screen not functioning properly
- Fingerprint not working
- Hibernate is only successful occasionally
- Switching between different working environments (office and home office) mostly never works due to graphic issues
- In general a lot of problems with multiple monitors
- Hard drive swapping occurs even though plenty of free RAM is available
- General and various issues with kscreen und xrandr
So, I guess I will surrender now and move to HP or Dell. For a laptop of ~2500€ I really do not want to have these kind of issues :-(
Update #6
Fun fact: I just received my Dell Precision 5540 with an Intel Core i9-9980HK yesterday.. and guess what..

tlpconfiguration file but I've never changed it. After installingtlpall my overheating problems went away.
