The PS5's cooling fan will be optimized in future firmware updates, depending on how hot or cool future games cause the console's processing unit to become. In an interview with 4Gamer.net (translated by orzkare on ResetEra), PS5 Mechanical and Thermal Design Engineer Yasuhiro Ootori revealed that Sony plans to update the fan based on the effects upcoming games have on the console's APU. The APU, or Accelerated Processing Unit, is the chip that powers the PS5 - it's a hybrid CPU/GPU. "Various games will be released in the future, and data on the APU's behaviour in each game will be collected. We have a plan to optimize the fan control based on this data," says Ootori. [ignvideo url="https://www.ign.com/videos/2020/10/07/ps5-teardown-official-hardware-deep-dive"] Ootori also notes that there are three temperature sensors on the console's mainboard and another sensor within the APU itself. All of the above will be used to control the fan speed, based on the "internal temperature of the APU and the highest temperature of the three temperature sensors." Ootori also spoke about how the team at Sony used computer-aided engineering and real-world experiments to optimise the console's airflow. "We made a transparent model of the chassis and observed the dry ice smoke flowing through it, and took temperature readings in each part of the system as we made improvements." Hopefully, Sony will decide to release a transparent model of the PS5, as that sounds incredibly cool.

In other PS5 news, here's a helpful comparison between the Xbox Series X and PS5 launch titles. Preorders for the console are currently sold out, but if more go up they'll be in our PS5 preorder guide right away. For everything you need to know about PlayStation 5, check out our PS5 guide.
