Fractal Terra CPU Fan Duct 92mm

The duct is designed for 10mm gap between the cooler and the side panel, which should be in the 4th spine configuration. After printing, glue a strip of 5x5mm foam linings at the edge to form a good seal with the side panel. You may need to slightly adjust the spine after installing this mod, depending on how well you mount the duct to the fans. In my case, I had to slightly relax the spine to give 0.5mm of clearance, as my foam is too thick and pushes right against the panels. After using this mod, I found that it reduces my average temperature by roughly 2C, which is just barely noticable. There's only a small drop in temperature due to the fact that the gap is not high enough to begin with. Still, a small improvement is still an improvement and I think it looks cool!

Printed in ABS, PLA is not recommended due to low glass transition temperature. If you like to adjust the height of the duct, you can remix the model and raise up/down the face designed for the foam linings.
