I recently PURCHASED this replacement fan for my PlayStation 4 and I am blown away by the difference it has made .As my tests showed, this fan helps regulate the temperature of my console more efficiently resulting in smoother gameplay and quieter fan noise. Installation was a breeze and the added bonus of being able to extend the lifespan of my console made it a no-brainer purchase. The only downside is that it may not work for all PlayStation 4 models..
