Can a laptop cool Core Ultra 5 115U, and will it throttle under sustained load?

  Short office loads are fine on a thin chassis, but sustained CPU, iGPU, or simultaneous dGPU work is limited by package power and shared heat pipes.

  Balanced mode for office work; for encodes or renders, choose two fans, adequate heat pipes, and a plugged-in performance mode that sustains power. If performance mode still cuts power quickly, the chassis cooling is the problem — a better machine beats paying more for a higher CPU label.
