Mistral-E Noctua Remix
thingiverse
A remix of the Mistral-E cooling duct by Leo_N because I was irritated by the loud 4010 standard Creality Blower. This one uses a 40x40x10 or 40x40x20 Noctua fan, or some other 24V fan if your don't want the hassle with the electronics. Don't solder a buck converter in between the wire, as they are not compatible with the PWM your mainboard sends out. I redrew the entire part in Fusion 360 in order to get good dimensional accuracy and clearance for the bolts of the X-axis tensioner. Best to print in a more heat resistant material such as PETG or ABS and to equip your hotend with a silicone cover. Use the longer two M2 bolts from the original blower to mount it to the fan casing.
