Replace the loud stock fan with a much quieter 5015 blower fan held in with this bracket, fitting neatly in the existing CR-10 SE shroud.
*Soldering is required, rotary cutting tool recommended to trim the fan
How to:
- Buy a 24v 5015 blower fan. I used the "MakerFocus" and its been working well so far.
- Cut away the nubbins on the blower fan. See attached picture.
- Trim off a portion of the blower duct at an angle. See attached picture.
- Either cut off and re-use the 1.25mm 2-pin connector from the original fan, or you can buy new ones. I recommend adding some heat shrink to the portion of the wires that will be closest to the heatsink on the hotend.
- Solder on the new connector. Be mindful of the positive/negative pins on the ORIGINAL connection, as those are correct. The new fan was reversed in my case.
- Remove old fan from shroud.
- Place the bracket over the blower fan as shown and insert both into the shroud. Use one of the original fan screws to secure it in place.
- Plug in fan and test.
- Slide and screw shroud back on. it's a pretty snug fit. Be mindful of one of the connectors on the PCB of the extruder that might be butting up against the blower fan. Be sure the fan clears that connection before pressing it in too hard or you will break it. It might require some jostling around but it does fit!
Please feel free to take this and make it better. I needed to trim off some plastic from the back of the part where the screw goes in to get it to fit flush. I carried those changes over to this model, but haven't tested it yet, so let me know if I need to adjust again.
