DIY Water-Cooled MacBook Neo Just Got A 23% Performance Bump. Here's How... - Yanko Design
"For everyday tasks, the answer is largely yes. For gaming under sustained load, the answer hits a wall at 105°C, where the chip pulls back its clocks to avoid cooking itself inside a case with no fan and no active cooling to speak of."
"ETA Prime ran the experiment that every thermally curious engineer has probably daydreamed about: what happens when you actually cool this thing properly? First, a custom copper heat sink bridging the chip to the aluminum shell."
"With just this mod in place, No Man's Sky jumped from 30-31 FPS to 58 FPS, average CPU temps dropped to around 83-84°C, and Geekbench 6 multi-core cli."
The MacBook Neo utilizes the A18 Pro chip from the iPhone 16 in a fanless design. While it performs well for everyday tasks, gaming performance suffers due to thermal throttling at 105°C. Modifications, including a custom copper heat sink and liquid cooling, dramatically improve performance, increasing gaming framerates and CPU benchmarks. The design emphasizes repairability with screws instead of adhesive, but the thermal limitations remain a significant factor in its overall performance.
