Sony has been installing different cooling fans on the PlayStation 5 (PS5), French tech website Les Numériques reports. The outlet noticed that there is a difference in the noise by two different PS5s, one being a review unit Sony provided and the other a unit they purchased. They proceeded and disassemble several PS5s and found five different fans in five different consoles. As seen in the image below, the cooling fan on the left is from the retail PS5, and the one on the right is from the review unit. The noisier fan (left) includes 17 blades that extend to the center hub. The one on the right has 23 blades that are slightly less thick.
However, the general rule is that the fan with more blades will require less power to move more air, thus providing better cooling. With the differences in fans here, it could be assumed that the fans with fewer blades require more power to provide more cooling and, thus, producing more noise. While it may seem unethical, this practice is, unfortunately, being used by companies for years. This has been seen with monitor panels, memory modules, and, more recently, in the SSD market. One thing that we don’t recommend is to replace the fan yourself because you’ll void the warranty.
