This model drops excess wind
The concept is to use it quietly
This mod may be a bit more difficult
5015-24v fan
5015-12v or 24v fan
Please note that the polarity of the fan electrodes may be reversed.
DC-DC adjustable step-down power supply
I need something that can be high pressure from 24vhttps://www.amazon.co.jp/dp/B010FJTHRC/
You can substitute 8 KΩ resistors with 0.5 W in parallel.
I don't recommend parallel resistors because it can't be finely adjusted and it generates heat.
This time, this base is used for power branching
I expanded the mounting hole to M3 and used ithttps://www.aitendo.com/product/7244
Universal board 32x32
The holes for mounting the board are M3 and the spacing is 25 mm.
fan.stl
Filament cooling fan
Uses 5015-24v or 12V fan
M3-10mm 6 pieces
2 M3-20mm
1 M3 nut
Is required
Except for one board mounting location and fan mounting
If you screw it in normally, you can fix it by self-forging.
At this time, do not screw in the screws excessively.

I am using two 3mm resistors with a 3.3KΩ resistor in consideration of heat generation.
I used hot bond for mounting
The Y-shaped jig (jigu.stl) is as shown in the photo.
After moving the hot end to the center
Put it under the work fan nozzle
A jig used to tighten screws and adjust the height.
rleft.stl
5015-24v fan used
Standard installation with loud noise
3010 Heatsink instead of cooling fan
It is a part to move 5015 at low speed to mute
M3-10mm 4 pieces
M3-20mm 1 piece
1 M3 nut
Is required
btom.stl
Prevents heat sink cooling fan wind from going to the hot block
I used a PLA product for more than 10 hours and checked it, but it didn't burn.
If possible, cut out a 0.3 mm thick aluminum plate into the same shape and use it.
At a minimum, output in ABS or do not use
left3010x2.stl
Use instead of rleft.stl
Use two 3010 fans that come with the main unit instead of the 5015 fan
Since it is a standard installation 3010 fan with a loud noise, lower the voltage
Even if it is moved at low speed, the sound deadening performance is inferior to that of 5015.
M3-10mm 4 pieces
M3-20mm 7 pieces
2 M3 nuts
Is required
3010HalfFanGuard.stl
Left3010x2.stl dedicated fan guard
left4010.stl
Use instead of rleft.stl
Use 4010 fans instead of 5015 fans
4010 fan quieter than 3010, but lower the voltage
Even if it is moved at low speed, the sound deadening performance is inferior to that of 5015.
M3-10mm 4 pieces
M3-15mm 3 or 4

Instead of the added 5015 fan, use two 3010 fans mounted on the body.
Even if you lower the voltage and move it at low speed, the sound deadening performance is inferior to that of 5015.

4010FanGuard.stl
Use 4010 fans instead of the added 5015 fans.
Lowering the voltage and moving it at a lower speed gives better results than two 3010 fans, but less muffling than the 5015.
