Can a laptop cool Core Ultra X7 358H, and will it throttle under sustained load?

  The 358H is a 16C/16T performance chip whose sustained all-core loads (compiling, rendering, export) draw real power, so cooling demands are mid-to-high. Chassis variance is significant: some machines sustain 80W+; others downclock at 50W. Check the model's sustained-load test (20 minutes in plugged-in performance mode, watching clocks and power) before buying — more useful than spec pages. If long heavy tasks are common, prefer dual-fan, richer-heatpipe designs.
