If you don’t have a Kill-a-Watt device, you would at least feel 100W waste heat. Does your PC get that hot?

  You might not. Given enough fans on the case they basically always feel cold. Mine isn't particularly crazy but at 100% utilization it would be using about 400w and it feels cold on the fan exhausts. You'll notice the room heat up though.

You would not, 100W not that much heat unless the room is very hot or it’s blown straight into your face (but even middling desktops tend to have very large fans, and will generally send the heat away from you, either towards a wall or to the ceiling directly). 100W is about what a human produces at rest.

    > 100W is about what a human produces at rest. Which is why humans are quite "warm to the touch", so yes, you'd definitely feel that.

      > Which is why humans are quite "warm to the touch", so yes, you'd definitely feel that. The original comment didn’t specify “to the touch”. Furthermore a (again) well-ventilated case will quickly expel heat, the case of my desktop PC is colder than ambient temp (that it’s aluminium and steel doesn’t help with heat retention either). I might feel some heat if I put my hands in the exit airflow, but even that is not a given: at a mere 100W the windchill of the back fan is likely sufficient to counteract the actual heat.
