Stealth 15

You're generalizing a WHOLE brand. It depends on the model. You probably mean MSI Stealth, which has poor thermals. I am talking about the Cyborg 15 which is a decent entry level model. https://ecommerce.datablitz.com.ph/collections/all/products/msi-cyborg-15-b13wekg-639ph-gaming-laptop-translucent-

The main laptop I used in this setup is this:MSI GS66 Stealth 15.6" Gaming Laptop (Intel Core i7-11800H/1TB SSD/16GB RAM/RTX 3060)As for the secondary laptop, mostly to handle lecturer's slides:LG Gram 14" Laptop - Obsidian Black (Intel Core Ultra 7 255H/16GB RAM/512GB SSD/Windows 11) I didn't use V

I tried using 2 my MSI laptops with closed lid, but horizontally. MSI GS63 Stealth and MSI Delta 15. Both of them have ventilation openings under the lid. Both of them overheated up to emergency shut down during heavy load. No damage to screen found though, but technically it also could be a problem

Worse laptop I’ve ever used. Circuit charge issue less than a year, fan spinning out of control if I don’t undervolt it, now the laptop can’t even turn on if I don’t open the lid fully which is stupid. Ain’t gonna buy another msi after this. Stealth 15 model by the way.
