3D model description

Mount to the 140mm fan opening on your PC case to help exhaust the heat out in a controlled fashion, and avoid all of that extra heat during those already hot summer days.

If you PC case has 140mm fan openings, you can place this vent over an existing 120mm fan in that slot using nuts and bolts around the existing fan bolts. If you have a 140mm fan in place already, then use the same fan hardware to mount this adapter and the fan to the case together.

Designed with a 4in duct opening allowing you to use common duct available from the big box stores and mega ecommerce giants. AC Infinity makes a nice black flexible hose that fits great and doesn't have the excessive aluminum foil finish on the outside though it is still foil on the inside.

For best results, I turned all of the other fans in my case to intake fans, and then the single fan under this adapter was the sole exhaust fan. This created enough positive pressure inside the case to exhaust the heat out the adapter on its own, but having the exhaust fan to help draw the heat out faster and expel it down then exhaust hose helped prevent heat saturation during long rendering and gaming sessions.
