Beyond that, at scale, is it good to have high-consumption computers all over the world before we have widespread renewable energy? Probably not ideal.
As far as energy use we’re it’s such a tiny amount of energy compared to any given appliance.
I think others are concerned with a trend that extrapolates to something insane power consumption where power use grows exponentially to megawatts where clock speed is growing asompotically to say 10ghz
Back in the Amiga era, I inverted the PSU fan of a very loaded 2000 (lots of memory, SCSI, Video Toaster, etc) and piped in the output of an air-conditioner directly to it (with a little bit of epoxy sculpting). It stopped crashing and worked happy for a long time until being replaced by a boring Windows box running NT.
Tbh I like it in winter, warms my living room up nicely. In summer I just run my aircons more, but I also usually game less because the weather is nice.
I doubt too many computers based on these parts will be running that hot for any significant time. It's much more likely to experience bursty loads - compiling something big, crunching a massive amount of data - than sustained ones, such as a build server or something similar.
If the CPU is managing GPU-based number crunching, keeping it busy will require a lot of GPUs, which will make the CPU's thermal output a rounding error next to the rest of the data furnace.
