However, the cooling performance is not really good in my opinion, a little weak but still OK.
I would imagine that this ventilation would fit very well for older consoles that are a bit warmer during gaming. Then the ventilation could relieve the hot console and additionally cool.
I also recommend an operation of the fan on an external power supply, so that the fan is not additionally burdened the power supply of the PS4 and thus also provides heat development!
+ Good workmanship
+ Perfect fit and fixed to the PS4
+ Good relief for older consoles or those that are significantly warmer
+ Reasonable price
- Unfortunately, a little too weak
Nevertheless, I think this is a good alternative to fan warm / hot expectant consoles!
