Hi Rubert. I'm Greg, 10 years awarded Windows MVP, here to help you.
As it's a hardware question I'd ask at the best hardware forums Tom's Hardware here: https://forums.tomshardware.com/
I'd also ask at Dell Community forums since they will have other owners of he model who can advise you better:

There isn't a Windows solution except that I'd install CoreTemp to monitor temps from the System Tray. Set overheat protection to Sleep or Hibernate if it reaches Core Max temp which it will calculate for your processor. See here:

I'd also ask a Tom's and Dell for guidance on cleaning the fans and heatsink to solve the overheat problem:

Report back results for each step so I know what else to suggest.
Feel free to ask back any questions. Based on the results you post back I may have other suggestions if necessary.
