Over the last couple of months I tried a lot of Linux distros on this 
laptop, and I got this sort of heating issue only due to some issue in 
the Intel Graphics / NVIDIA driver. For example with an Ubuntu 
installation it was a case of outdated drivers for both - I upgraded 
both the kernel and the NVIDIA driver and then it got solved. And then 
in an Arch Linux installation I got the same heating problem when 
NVIDIA open-sourced their driver (the new driver had some issues), and 
following some advice it got resolved by adding ibt=off in the kernel 
parameters. And as I mentioned in a previous mail, this laptop is new 
and I have dual booted it with Fedora Linux which runs completely okay, 
so I don't think this is a hardware issue ...

I'll go through the NVIDIA driver packages then. Thank you for the 
pointer!

Thanks again for your help!
