Video lets you actually see the incredible MacBook cooling system at work
Why cooling matters
A computer’s real-world performance depends on more than its chip. When a device becomes too hot, it may reduce performance to avoid damage. That can mean a chip reaches its theoretical maximum only briefly before slowing down. Effective thermal management is especially important in a laptop such as the MacBook Pro.
A redesigned thermal system
Apple said the new MacBook Pro has a completely redesigned cooling system. The company said its thermal architecture supports sustained performance from M5 Pro and M5 Max, even in a lighter design, while directing warm air away from the display.
Heat moves toward the hinge
In the older model, the demonstration shows heat moving outward and upward through the display. The PROLED model instead directs heat toward the back of the laptop through the hinge.
The comparison is especially relevant when a laptop is closed and connected to an external monitor, a situation that makes cooling more challenging. The test results show a dramatic improvement in the newer model, according to the report.
Key points
- Geekerwan used a fog machine to show airflow from two MacBook Pro models.
- The older model sends heat upward through the display, while the new one directs it through the hinge.
- Cooling helps prevent heat-related performance throttling, particularly during sustained laptop use.
- Testing showed a dramatic improvement when the newer laptop was closed and connected to an external monitor.
