Cold air intake for CPU cooling.

thingiverse

A custom-designed cold air intake for CPU cooling on MSI B250M Bazooka motherboards and other boards with similar CPU positioning. Specifically, it's crafted to be a direct fit in the Komplett 2017 Winter Gamer PC. If this design doesn't suit your PC, consider using it as inspiration for your own ducting projects. This intake alone brought down the full Prime95 load temperature from 90°C to 75°C on my I7-7700 CPU. It achieves this by letting the CPU fan blow cold air directly from outside the case instead of recycling hot air inside the case. This is useful if you have a small heat sink and want better performance without buying additional parts. Trimming of the square end will likely be required for motherboards other than the MSI B250M Bazooka. The short tube portion fits in the duct opening and can be printed to any height by adjusting the X-height in the slicer, serving as a spacer if your heat sink and fan are lower than mine. The round end fits over an Akasa AK-959CU 96 mm outer diameter heat sink fan, requiring no additional attachment. Hot glue is a good method for attaching it to other fans. If it's challenging to fit, suggest cutting more slots around the edge in addition to the one already present on the model. I had to do this with mine, which is a slightly tighter version. I enlarged the diameter by 1% on the one I uploaded.
