Cooler Master Q300L Airflow Kit

My computer crashed constantly because my RX590 overheated excessively. When playing games, the PC would run at 82°c. Upon realizing that poor airflow might be to blame, I conceived a plan to increase air circulation by creating a funnel that would allow more air to reach the fan. This innovative solution successfully reduced the temperature to approximately 63°c. Although satisfied with the initial results, I wasn't entirely pleased with the air discharge on the back side of the PC. Therefore, I employed the same tactic to create additional space between the fan and the case. Unfortunately, this adjustment yielded only a 2-3°c difference in temperature reduction. Notably, the funnel performed significantly better than anticipated, serving as a pleasant surprise. The dimensions of the scraping holes for Spacer.stl are 105mm wide by 120mm high, while those for SpacerBox.stl measure 105mm wide by 104mm high. Funnel.stl features scraping holes that are 180mm wide and 135mm high, all designed to accommodate 120mm fans. If you plan to install two funnels and position the control unit on the right side of the housing, be cautious when mounting the funnel to avoid damaging cables. I printed the design with supports, but believe it can be successfully printed without them. SpacerBox.stl represents a minor improvement over Spacer.stl, incorporating adaptations for SquA fans that help close gaps while ensuring compatibility with other fan types. This design was uploaded twice due to an initial upload issue on Thingiverse, which prevented it from appearing in search results.
