We recently bought a new laptop and then I saw this review of gaming laptops. We didn’t buy a gaming laptop as such, but this section about the Razer Blade 2016 – the more recent Razer Blades use less-than-optimal-for-gaming graphics cards and were therefore irrelevant for that article – is worth noting anyway:
The Blade’s surface temperatures, though, were simply unacceptable. As you can see in the chart above, the Razer’s WASD keys were a sweat-inducing 43 °C (109 °F), the K key was 49 °C (120 °F), the strip of metal above the keyboard was a scalding 54 °C (129 °F), and the underside of the chassis was 52 °C (125 °F). […] Such surface temperatures are similar to what I saw when testing the 2014 Razer Blade, which left me with a first-degree burn on my leg after I used it on my lap for a 15-minute stint.
I had honestly not considered surface temperature a factor I should have looked into.
