9CM double fan length 18.6 cm * width 9.2 cm The interface can be connected to the main board 3/4 pin (the main board fan interface 3 pin 4 pin can be plugged in) or the power D port 4 pin, Delta's 4 pin is power supply + alarm line + PWM temperature control line
Scope of application: Fanless passive heat dissipation graphics cards are very simple to add fan solutions, and some supplementary heat dissipation solutions with fan graphics cards.
