After so many reports on XboxOne Leaking Liquid, now it’s happened to PS4 as well. A dry liquid seems powder like on back in vents of Ps4, we have found some pictures from very useful source (Neogaf board).
You can see it’s still covered with this fluid.
After removing the cover it’s looks weird. What is that white stuff.
In this picture user remove the liquid, the liquid is looks like powder. It’s is easy to remove and with no smell at all.
According to user facing this problem, when he bought his ps4 at that time there is no white stuff on it , but after 1 week now he is facing this strange problem..
