Here’s how the Mac Pro ventilation works to keep it quiet even at peak performance

Popular Mechanics

Getting the Mac Pro to perform smoothly when it’s needed for a lot of power isn’t something that can simply be solved with good specifications and software optimization. It requires a good approach to the computer in all areas, including the design of its exterior. The Mac Pro engineering team explained in a new interview how they keep the Mac Pro from “suffering” even when it has performance load peaks.

In an interview with Popular Mechanics, the team led by Chris Ligtenberg, Senior Director of Product Design at Apple, explained that they built the Mac Pro with three axial fans in the front and a fourth fan in the back . These four fans are responsible for circulating air inside the Mac Pro so that the proper temperature is maintained at all times, even when it has to be at full power.

Because of the way the blades of these four fans are built, they too have managed to prevent them from making the typical fan noise in computers. The asymmetry of the blades manages to avoid the noise and offer a quieter ventilation.

A rack specifically designed for refrigeration

One of the most distinctive features of the Mac Pro and the Apple Pro Display XDR is the grid feature. The aluminum enclosure has a hollowed-out surface that creates an interesting texture. This structure is not only for aesthetics, but also has to do with the cooling of the Mac Pro and the Pro Display XDR.

According to John Ternus, vice president of hardware engineering, the structure is designed to prevent a lot of dust from entering while keeping the device cool. They explain that it is a design similar to what you can find on a motorcycle or the engine of a car. The Mac Pro case ensures that the machine gets 20% more airflow than the Power Mac G5, a similar sized chassis to the Mac Pro.

Finally, the design of the Pro Display XDR as well ensures that it works optimally in both portrait and landscape modes without any problems. Without the right airflow, the individual LEDs in the display would heat up and could not reach their optimum brightness. It is certainly curious how the external product design directly affects the performance of the devices.
