Make Matlab work for several hours can damage my laptop?

Hi all,
sorry if my question is a little naive but I'm not too expert. I need to do a work on Matlab and my university tutor said me that for this work I need to make several operations with very big matrices on Matlab and all the work could take up 2/3 hours.
Now, I always used Matlab for very lower time in respect to that case, so I wanted to ask you if it's possible that my notebook could be damaged if I make Matlab work for several hours.

Massive, long computations with large matrices, etc., can indeed heat my computer up, forcing my fan to kick on. I use a stationary system though, so it has a sufficient internal fan that can handle the load. So I have had this computer running flat out for multiple days at a time, with all cores in operation.
When my wife was using her laptop for some extensive work a few years back, we got her an external fan, one that the laptop would rest on. We also found and installed a temperature monitor application, one that could report the temperature in various components, so the graphics card temp, CPU temp, etc. You could see the difference with the external fan on.
At the very least, you might want to raise the laptop from the surface it rests on. Air flow under the case can allow it to cool down.


Quality laptop makers expect that someone might play a game for an hour but do not expect a full day.
Any laptop worth its salt should shutdown before damaging itself. That said, many laptops are not worth their salt.
Computers do generally shut down or start to error badly enough to crash if they get hot enough. However, in the meantime components wear when at high temperatures that are sub-critical. Lithium Ion batteries in particular wear out with heat. They used to explode, until technology was reformulated to have them expand instead of explode.
