Cooler Master Q300L Airflow Kit

My PC crashed all the time because my RX590 got too warm. When playing games, the PC ran in something of 82°c. After realizing that the airflow could possibly be the reason for this, I thought that the fan could provide more air using more holes of the case, so I created a funnel that actually reduced the temperature to about 63°c. Unfortunately, I wasn't satisfied with the air discharge on the back side, so I used the same thought and put in some more space between the fan and the case. Here unfortunately only with just 2-3°c difference. 

In any case, the funnel worked much better than expected. It was a really nice surprise.

The scraping holes of Spacer.stl are 105 mm wide and 120 mm high.

The scraping holes of SpacerBox.stl are 105 mm wide and 104 mm high.

The scraping holes of Funnel.stl are 180 mm wide and 135 mm high.

All are for 120 mm fans.

To avoid cable breakage, the mounting of the funnel should be done carefully. Especially if you want to mount two funnels on the front side and the control unit is also mounted there.

(I printed it with supports, but I think it can be printed without)

(SpacerBox.stl is a small improvement of Spacer.stl. The shafts are adaptations for SquA fans to close the gaps. But they should not hinder other fans.)
