This makes the fans very quiet. So make sure to adjust the fan speeds in the slicer.</p><p><i>This is a Remix from this Print:</i> <a href="https://www.thingiverse.com/thing:3697665">https://www.thingiverse.com/thing:3697665</a><br>I set the fan mount 2mm lower because it blew too much against the nozzle.</p><p>Both fans should be of the same type.<br>The three original attachment points are used, so only additional screws and nuts are required to attach the new fan.<br>To connect the second fan, the <strong>black </strong>and <strong>red </strong>cables of the two fans have to be joined. The yellow cable (speed signal) is only required by one fan.<br>It is best to connect the cables at the point as shown in the picture or in the Einsy case.</p><figure class="image image-style-align-center image_resized" style="width:75%;"><img src="https://media.prusaprinters.org/media/prints/63279/rich_content/271993b9-595e-4458-beb1-2354844a9928/20210413_174221.jpg#%7B%22uuid%22%3A%22ea5b70a1-a2fc-4f6e-9116-2b18b9bfbc4f%22%2C%22w%22%3A4032%2C%22h%22%3A3024%7D"></figure><p><strong>If you like check out </strong><a href="https://www.prusaprinters.org/social/38556-extrutim/prints?o=liked"><strong>my other designs</strong></a><strong> too!</strong></p>
