After getting annoyed by the loud Controllerfan, i decided to use a leftover Fan of my Computerbuild. A 80mm “be quiet” fan. After getting one side off by 2mm and reprinting the Top shell, and breaking off a part by accident, this is the outcome.
The normal 30mm (or so) Fan is run on 24V the PC Fans are usually 12V, so i had to add a Buck-boost coverter
works like a charm now. The Printhead coolgin fans are now the most noise the Printer makes in Idle. Didnt run a print yet, hopefully the Drivers wotn toast themselfs.
Got two short videos to compare sound but wont uplaod them exept requested.
