- Apple Silicon Mac owners running sustained machine-learning jobs, renders, or builds
- Worth noticing
- Usage triggers only at 70 °C or hotter; fan changes are written to the local macOS log with readings and a trigger.
Field notes
The rule combines independent temperature and usage thresholds: usage triggers only once the Mac reaches 70 °C, while temperature has its own limit. A threshold must remain crossed for 10 seconds before maximum fan speed engages; release requires 60 seconds below limits. The page includes two sample log lines from an M4 Pro test and says logs stay local. It also says the demo chart is invented, not a measurement.
