ZBook Fury 17 G8 (i9-11950H + RTX A3000) — GPU thermal throttling at half its power budget despite fresh repaste, clean fans, and AC'd room. Anyone seen this?
HP ZBook Fury 17 G8, i9-11950H + RTX A3000. Fully repasted both CPU and GPU with PTM7950 (proper break-in cycles too), fans are clean and running at full speed with strong airflow, room is AC'd. Still, GPU hits thermal throttle ("Thrm") at only 40-60W out of its 80W TGP budget, at 86-88°C, clocks drop to ~1000-1300MHz. CPU sits at 94-99°C on just 41-49W. Isolated CPU load (capped it hard) and GPU behavior didn't change at all, so it's not CPU heat bleeding into the GPU. GPU-Z Hot Spot delta is normal (~7°C) so it's not a bad die contact either. Compared it to benchmark videos of weaker laptops (Dell Precision w/ older Quadro RTX 3000) sustaining full 78-80W at only 67°C. Anyone seen this on a ZBook Fury G8 / RTX A-series before? What am I missing?
