Are you sure that it isnt simply your system that is getting overheated?
I had this problem with my old computer. It helped by turning down the graphics, so try turning the graphics to lower and test.
ELSv8 problem can simply be because the cars aren't configured with ELSv8 and only works with ELSv7, So try ELSv7 instead of ELSv8 if you don't want to configure the ELSv8 yourself!
Have a great day and get back if it worked or have any more questions, i'll get back as fast as quickly!
