First attempt at a fully silent hot end !
I made a new fan mount for two 80mm fans for my Ender 3 Pro and it works pretty well !
With a silent motherboard and 120mm PSU fan mount, now my printer is completely silent !
2020-10-31 Update
Better BLTouch placement
2020-10-25 Update
Now in two parts to print easily - Two M3x6 bolts and nuts to join them
Optionnal BLTouch mount
Added clearance for X axis
Features :
Dual 80mm fan mount
Fits Ender 3 stock axis
Uses original hardware to mount on printing head
To come :
Add LED mount
Additional information :
Hotend cooling fan is powered through an adjustable buck converter using 24v direct from PSU and set to 10v output
Part cooling fan is powered from the original fan header of the motherboard, I set max cooling fan speed at 25% in Cura, but it's not ideal... Fake PWM is provided by the motherboard, switching 0 to 24v at 8Hz, some 12v fans won't survive this ! The fan i'm using is OK with this, but makes a 8hz noise... I'm looking for a better solution ...
2020-10-25 : Ordered an EBM-PAPST 8414NGL (24v/1500rpm) to replace part cooling fan
