Pentium 166MHz to 60mm Noctua

thingiverse

I acquired an old PC from 1997 equipped with a Pentium processor, featuring a 52mm cooling fan that was both loud and underperforming due to its probable brushed motor design. To upgrade this outdated system, I found the largest available Noctua fan and created an adapter to fit it seamlessly. The original thickness of the old fan served as the base for the new mount, ensuring compatibility with existing screws and sufficient clearance from the heat-sink's protruding side fins. For those who require a customized height, simply embed the model into the print bed before exporting the G-code. The dimensions of the original fan were 52mm x 52mm x 20mm, with mounting holes spaced 42mm apart. In contrast, the Noctua fan measures 60mm x 60mm x 20mm, boasting mounting holes that are 50mm apart. To successfully install this new cooling solution: 1. First, print a small base and supports along the outer rim. 2. Next, screw the mount into place using original screws on the heat-sink. 3. Then, secure the Noctua fan to its mount with standard fan mount case screws, which are provided with the fan. 4. Finally, let the system cool efficiently.
