Petr Škuta Mac Pro 2019 surprised with its design, which benefits from the proven construction of its predecessors. The cooling, which will play a key role in such a powerful computer, will also be at a top level.
Developer and designer Arun Venkatesan detailed the design and cooling of the new Mac Pro on his blog. His observations are very interesting, as he notices even small details.

The chassis of the 2019 Mac Pro is largely based on the Power Mac G5, which was the first Apple computer of this design. It was also intended for professional use and relied on powerful hardware. It had to be cooled down accordingly, especially under full load.
The Power Mac G5 relied on four heat zones that were separated by plastic partitions. Each zone relied on its own fan, which dissipated heat from the components through metal heatsinks to the outside.
At the time, it was an unprecedented construction. At that time, a common computer cabinet relied more or less on one zone, which was bounded by individual sides.
The division of this large space, where all the heat was accumulated, into individual smaller zones allowed concentrated heat removal. In addition, the fans were started according to the need and the rising temperature in the given zone. The entire cooling was thus not only efficient, but also quieter.
Apple wasn't afraid to inspire older generations and adapt the design of the new model. The 2019 Mac Pro also relies on zone cooling. For example, the motherboard is divided into two areas by a metal plate. Air is drawn in by a total of three fans in the front part of the computer and then distributed to the individual zones. A large fan then draws the heated air from the back and blows it out.

Cooling is excellent, but what about dust?
The front grille also plays a key role in cooling. Due to the size and shape of the individual vents, the front is barely 50% the size of a standard all-metal front wall. It can thus be said that the front side is literally open to the air.
So it looks like unlike MacBook Pros, Mac Pro users won't have to don't worry about overheating or underclocking a hot processor at all. However, there is a question that seems to have not yet been answered.
Even Venkatesan does not mention protection against dust particles. Also, on Apple's product page, you won't find clear information about whether the front side is protected by a dust filter. Clogging up such a powerful computer with dust can cause problems for users in the future. And not only in the form of greater strain on the fans, but also settling on individual components and the resulting heating.
We will probably find out how Apple solved this issue only in the fall.
