GeeCoolGaming bursts and sustained all-core encoding on the 165H share CPU power, GPU TGP, and the dual-fan heat-pipe system. Plug in, switch to performance mode, and watch GPU power, CPU power, and clocks for 20 minutes.
If clocks slide noticeably or the GPU stays below published TGP, the chassis power wall is the limit. Prefer a thicker multi-heatpipe model, then check balanced mode to see if the noise and battery hit are acceptable.
