I even bought this fan charger from ebay and since my PS4 in my room quickly overheated, I had to replace the two fans and additionally two block this, so with four fans (Industrial fans;)) is my PS4 now well supplied and does not overheat more, just loud, it has become, but that does after some time no longer :) if you want to block 4 fans you have here and cut there in the housing and which way the dimensions are as the standard fan installed in the housing are 60x60x15
