    Yeah, anyone that says this isn't needed or no one asked for has literally not used an x86 laptop for the last two decades. It's not just thermal design of the laptop case that's the problem. Intel/AMD systems run extremely hot and it doesn't take much for these things to burn even if they are tuned to run cool and quickly throttle. This easily happens with normal use even on well air cooled laptop designs. I used to be resigned to this as every laptop I've ever owned needed to be handled with care when running anything beyond a text editor....

    Until I bought an M1 MBP for going back to school. I spent all day playing Wasteland 3 on it the day after I bought it and it was just barely pleasantly warm 8 hours later when I shut it down for the day. No special external fans, no props to clear air passages. It sat flat on my desk the entire time. I never even noticed any sound from the internal fan. (M1 MBP has a fan, M1 Air doesn't) This is literally the first actual "lapable" laptop I've ever owned even when it's running under load. The quality of the M1 chip is pretty much as advertised.

    My Dell G5 Skylake is so badly outclassed it's unlikely to be taken off the shelf even after I get it repaired (keyboard has a line of intermittently bad keys) That G5 can get so hot the built in keyboard can be uncomfortable to use.

      This functionality will not be included in 5.11 since it was outside of the two week merge window for new functionality.

      Rafael send another pull request without it.

        I use my laptop on a table. Thanx for the louder fans, I appreciate it.

          I've had three Lenovo's over the last decade, models from 2011, 2013 and 2015. The older two ones are admittedly quite weak. The latest one is still in use, has a Skylake i7 and a very thin magnesium case. It never became uncomfortably hot and I've done video editing (with software encoding on CPU, not GPU accelerated) on it.
          Maybe you just had bad luck and bought the worst models on the market?
