Please print it in PETG or ASA / ABS.

It´s simple to connect a new very silent mainboard fan from Noctua (40x20mm https://amzn.to/3TDpWnI) - IF YOU CAN SOLDER your cables!
The cable colors from Noctua are not similar to the original fan cables. Please have a look at this Youtube video https://shorturl.at/yRV34
