Water cooling MacBook Neo: how much gaming performance improves (native + Crossover)

A source-backed breakdown of ETA Prime's cooling mod test on MacBook Neo, covering thermal throttling, No Man's Sky native gains, and Fallout 4 performance via Crossover/WINE.

Reference video

This video focuses on thermal throttling and sustained performance rather than a broad game catalog.

The presenter compares stock cooling against a copper heat-spreader style mod and then an external thermoelectric cooler setup.

For compatibility tracking, the transcript gives concrete game-level data for No Man's Sky (native path) and Fallout 4 (Crossover/WINE path).

Workflow workarounds used

  • If thermals are limiting FPS, improving heat transfer can raise sustained clocks and recover performance that stock cooling cannot hold.
  • A basic copper/thermal-pad style mod delivered a major jump before external cooling was even added.
  • An external thermoelectric cooler reduced idle/load temperatures further and improved sustained gaming behavior over longer sessions.
  • Treat this as an enthusiast workflow: useful for experimentation, but not required for typical users and not equally effective in every title.
  • When comparing results, keep settings, resolution, game mode, and VSync state consistent to avoid misleading conclusions.

Game-by-game results

No Man's SkynativeStock run shown around 30-31 FPS under thermal throttle; copper mod raised this to ~58 FPS; long-session test reports ~80 FPS average with stronger coolingExamples shown at ~1408x881, enhanced/medium, Metal scaling set to balanced — Transcript shows stock temps around thermal-throttle territory and improved temps/perf after cooling changes.0:45
