HP Reverb G2 Facial Interface with Fan Cooling

HP Reverb G2 got foggy after while playing with DCS and decided to look for cooling solution. I found the facial interface from Steve and tried it right away. Well, there was some improvement but it will be better to get fan cooling. Then I found the solution provided by Kelvin. Without remix, it adapted 30mm fan but the blow out holes do not match the openings on facial interface. Therefore, I remixed the facial interface to open two bigger holes and remixed the fan duct to fit 40mm fan with matching dimensions.

Here is the velcro sticky back used to attach the fan duct on the G2.
