WD MyCloud EX2 Ultra fan cover replacement, noise reduction

prusaprinters

<p>As a user of the WD MyCloud EX2 Ultra network drive, I was very disappointed with the noise made by the very small internal fan. At night the noise was totally unacceptable, especially when the drive was performing a sync or a large file transfer was running. So I disassembled the drive, removed small fan, and plugged a 70mm fan into its connector. This worked very well! Unfortunately the 70mm fan did not fit inside the case in any way. So I designed an adapter that encloses the new fan inside and replaces the top cover of the drive. Thanks to this the temperature inside the case is lower and the fan can hardly be heard, it runs much shorter and at a lower speed. The adapter is not permanently attached to the case, it rests on the case under its own weight. Please note that the fan should be mounted in such a way that it will suck warm air out of the case, not push it into the case!</p><h3>Print <strong>instructions</strong></h3><p><strong>Printer Brand:</strong></p><p>Prusa</p><p><strong>Printer:&nbsp;</strong></p><p>I3 MK3S</p><p><strong>Rafts:</strong></p><p>No</p><p><strong>Supports:&nbsp;</strong></p><p>Yes</p><p><strong>Resolution:</strong></p><p>0,2</p><p><strong>Infill:&nbsp;</strong></p><p>15%</p><p><strong>Filament:</strong></p><p>Plast-Spaw PLA, PETG, ASA, ABS Any&nbsp;</p><p>&nbsp;</p><p><strong>Notes:&nbsp;</strong></p><p>You may use PLA filament, there are no very high temperatures in the drive.
