How Long Do Gaming Laptops Last? - LaptopTalks
They mention cooling to extend the lifespan.
What I do is put little pads under each foot. About 1 inch by 1 inch(2.5cm) and about a quarter inch tall (6.5mm). It helps cool it off by a surprising amount. Laptop makers put almost zero space underneath for air to enter those grilles.
I've had it for 7 years. Much longer than they claim. Still runs and looks perfect.
I also got it in a good sale for under $700. You can find them reasonably cheap if you long long enough.
I7 CPU is still ok but the GPU is increasingly showing it's age.
It's a little surprising how few laptop makers make them upgradable. Maybe they make more money just selling people a whole new laptop.
I finally found another cheap one with all of the connectors and slots that I want plus a DVD player and the 17.3 inch screen. Even heavier than my old one which is ok. I think they put too much emphasis on shaving off every last mm and gram. I'd rather have more capability.
