I just bought a Asus ROG Strix GL503GE laptop. lm_sensors is reporting 10 degrees higher temperature for the PCH than what I get on windows with hwinfo/hwmonitor
Windows 10 : 50-52 degrees Celsius
Linux: 60-63 degrees Celsius
Now I am wondering if this could be a bug with lm_sensors or is the PCH really running hotter with the linux kernel.
The laptop sports an i7-8750H running on Intel HM370 (Cannon Lake-H)
CPU on the other hand, runs around 45-47 degrees celsius same as Windows. It is the PCH temperature thats bothering me.
The laptop has an optimus setup with dual GPUs. But I don't intend on using the Nvidia GPU on linux and have switched that one off using bbswitch.
I know coffeelake is pretty new and at times hardware support in Linux takes a while to catch up.
Just wanted to check in and see anybody had similar experience with Coffeelake.
Any thoughts ?

Core 5: +42.0°C (high = +100.0°C, crit = +100.0°C)
And the fan speed don't increase when the temperature is high.
Any help?

I'd say that the GPU is not actually deactivated?
"Activate" it, load the nvidia driver (or just use optirun, denepnding on your setup) and check the GPU temp.
nvidia-smi --format=csv,noheader --query-gpu="temperature.gpu"
