The article also notes that Ootori considered using two separate, smaller cooling fans to make the PS5 smaller, with one fan for each side of the mainboard.

However, this information for Ootori clarifies that the airflow needed for both sides of the mainboard is the key factor in that thick fan and thicker console design.
