That’s not how it works, an “idle” CPU is already generating a not insignificant amount of heat. That why you measure the difference against ambiant air if you’re at all serious about it.

Usually that should mean it cuts the difference ambiant and CPU in half. Anything else would just be stupid or a lie.

Yeah okay but by that logic you’d also have to quantize time and the suffering would end either way in a finite amount of time.

Many mice can scroll sideways by tilting the scroll wheel. If that’s something you use often enough, maybe that’s something to consider
