The additional fan of DBPOWER for the Playstation 4 is powered by USB and has 5 additional fans. Laterally there are controllers for ON-OFF-Auto. In addition, you can still switch to Turbo. The USB cable is long enough and can be used optimally on the installed outputs. Through an intelligent plug-in attachment, the module is installed easily and securely. Processing convinced. Although everything is made of plastic but in spite of all the product for the application site is sufficiently stable and well thought out. I myself use it in conjunction with a USB hub expansion for PS4 and am absolutely satisfied.
