I noticed one day when I went to turn off the ps4 it was burning up so I've got this to lift it up off the shelf and allow air ventilation around it. The added fans speed up the process.
There has been nothing but cool gameplay since.
After having the blue light of death on my ps4 I have bought a replacement, one suggestion was to keep it well ventilated, and this device ticks all the boxes.
Very smart, easy to set up, works on normal.
