Apple engineers explain the innovative features of the new Mac Pro

Apple engineers Chris Ligtenberg and John Ternus gave details of some of the innovative features of the cooling system included in the Mac Pro and Pro Display XDR design, which were launched earlier this week.

In order to achieve the processing power of the PowerMac Pro‌ without melting, Apple engineers had to devise new ways to exploit the “laws of thermodynamics.”

The Mac Pro has an active internal cooling of three axial fans in the front of the case and a fan in the rear, all of which had to be developed internally because the standard fans would have been too strong.

“Dynamically they are balanced, but in reality, they are randomized in terms of the frequency of the blade. This means that by having this variation, you don’t get great harmonics that tend to be super annoying. ”

“That solution was borrowed almost entirely from car tires,” says Ligtenberg. “There’s a little math behind this, but you can create broadband noise instead of total noise with that technique.”

Something loud but pleasant in tone may be more tolerable than something quiet but irritating. but you can have something that actually has a lower SPL that irritates your nerves and sounds really horrible,” says John Ternus, vice president of engineering Apple hardware and responsible for the development of Pro and Pro Display. “We want to get really excellent performance in which, or you can’t hear, or if you can hear, it’s a kind of pleasant noise.

It takes a lot of analysis to find out how to optimize for that. ”Apple hopes that ‌Mac Pro‌ users won’t even realize fan activity inside, but they are the visible grilles of boring metal holes in the part front and back of the case and the back of the Pro screen that provides passive cooling. “[The pattern] gives us a lot of surfaces, which is very beneficial,” says Ternus.

The Pro display has fans for specific components, but boring metal holes are what keeps that LED panel cool enough to run so bright. It was not possible to use a traditional finned case heatsink, because the monitor can be used both vertically and horizontally.

Rotating the screen 90 degrees would be reduced with the flow of air through the fins, but the hemispherical holes work the same way, regardless of how it is facing up. “[For the screen] we wanted a free flow [of air] through the channels, regardless of orientation,” says Ternus.

According to Apple, the renewed appearance of the “cheese grater” achieves about 20 percent more airflow compared to the Power Mac G5 that preceded it.

Price

Apple is accepting orders for the iMac Pro‌ (starting at $ 5,999) and the Pro Display XDR ($ 4,999) on its website, with delivery estimates of ‌Mac Pro Entrega within one or two weeks after an order is placed.
