gollark: Right, I forgot Intel had actually released working 10nm products now. Back to confused, I guess.

gollark: Oh, so they're harder to cool despite the same total heat output because of the greater density of 7nm? That does make more sense.

gollark: I guess that you could maybe, I don't know, have differences in *measured* temperature depending on where the thermal sensors are, or have different fan control. But that couldn't really change total heat output.

gollark: The *only way* it can heat up is by converting electricity to heat when operating.

gollark: That makes absolutely no sense.
