Sony will be able to control the PS5 fan dynamically with software updates

Sony podrá controlar el ventilador de PS5 de forma dinámica con actualizaciones de software 32

The PS5 fan was one of the components that most caught our attention when we saw the official breakdown of the new generation console. Sony used a huge turbine-type fan, a design that, as many of you may already know, takes care of remove hot air from inside.

Turbine-type fans get a bad rap, but the truth is that they doare very useful when the interior space is limited, and they are the best option when it is not feasible to resort to the typical radiator and fan design on each specific component, or when, even if this is possible, the end result would be a cooling system so poor that working temperatures would end up being unsustainable.

With this in mind, we can fully understand why the PS5 fan uses a turbine-type design. Sony has integrated a huge radiator that prevents heat from concentrating on key components, the chassis design facilitates the entry of air from outside, and the fan is responsible for removing the hot air so that it does not accumulate inside the console.

Looking at the internal design it is clear that Sony made the right decision, and had no qualms in acknowledging that the size of the fan, and the cooling system in general, they had been the “culprits” of the PS5 being so huge. They could have used other configurations, but it would have involved mounting more small fans and resorting to controllers that complicated the final design.

PS5 fan will work dynamically and customizable

That’s how clear it has been Yasuhiro Ootori, director of mechanical design and engineering at Sony, who has explained in an interview that ps5 fan operates below its theoretical maximum, which means that the Japanese company has chosen to implement a less aggressive fan profile that prioritizes the noise-performance balance.

Sony will be able to dynamically control the rotation speed of the fan to adapt it to the specific needs of the PS5 throughout its life cycle, and also depending on the requirements and particularities of each game. Thus, for example, if we run a title in performance mode and the temperatures are different from those registered in quality mode, the fan rotation profile would be adjusted accordingly to offer optimal operation.

In those situations in which the working temperatures are very high, turning speed could be significantly increased to reduce heat. This is critical as, as our regular readers will know, the PS5 uses dynamic frequencies on the CPU and GPU, and temperatures must be kept below a certain threshold to reach their maximum values. High temperatures would force to reduce frequencies, and this would have as a consequence a significant drop in performance.

Sony is going to use different profiles with the PS5 fan, and has also confirmed that can update them via software if necessary, an interesting and perfectly understandable move since, as we have said, the performance of the PS5 will largely depend on the effectiveness of the cooling system. To ensure a good user experience and total reliability, the Japanese company will use values ​​continuously monitored through the three sensors that the PS5 mounts.
