:^/ Sir, 100°C is the boiling point of water.  It is not normal, (nor even safe) for a laptop to get that hot.  One of those aftermarket cooling pads with the fans in them may be the way to go.

Call Dell.   I had the problem last year with my laptop and it crashed completely and lost everything.  Back up your files and call them.   My laptop is starting to get hot again so I may need to call them again.    Call now while it's still under warranty.  And GOOD LUCK with them!

Thanks for getting back to me. I did buy a cooling pad and that has made little to no difference in the temp.  What is a reliable way to determine the temp?  Is the NVIDA MonitorView good?  I can't even put the laptop on my lap otherwise it will burn me!  It does get very hot.  It's under warranty, is it worth a call to Dell?  Thanks for your help

Use I8kfangui to monitor temps.

Use some "canned air" to blow out the vents. Dust bunnies can hinder air flow through the computer.

Most video processors have a shut down temperature of around 125°C. At lower temperatures, they will throttle down in speed to lower the temperature. Normal temps should be somewhat lower than you are getting.

Dust builds up inside your system after a few months and it will get hotter and hotter until it dies.Clean  out the dustbunnies regularly to keep your system running cool and fast.

If you still have your warranty, then use it.  Let them tell you its not a big deal or that you have a major problem.  It would be different if you didnt have the warranty and the cost to send it in or have it looked out was outrageous.  Use the warranty often until it runs out.  they should be on the phone checking, with you, if the can of air worked.  If it didnt, then let them run down the list of what to do until they decide to send someone out or something.

How do you clean it?
