Ender 3 V3 Part Cooling Upgrades?

Hi everyone! Been printing over 150 hrs on two V3 Plus machines.

I have noticed that the cooling at ‘Normal’ speeds isn’t enough for overhangs, bridges, etc. I upgraded the part fan shroud/duct, but I think the fan is underpowered.


Ender3 V3 Plus 0.15A Fan w/Upgrade Duct

The current fan draws 0.15A at 24V DC. I found that the K1 fan draws 0.3A at 24V DC, so twice the power, perhaps. Any idea if the board on the Ender 3 V3 head can handle the extra draw or its max amps? Any other suggestions on how to improve the part cooling?
K1 0.3A Fan
K1 0.3A Fan

According to creality the hotend boards on the v3 and the v3 plus are the same

Right. I am looking at the fan from the K1 though, which seems to draw twice as much current as the fan on the V3 Plus. Hoping that results in better air flow, just not sure if the board can take it.

It shouldn’t make any difference as the boards are both the same. If you want a more powerul fan (RPM), you could use a computer fan but be aware that they run at 12v and draw around 0.2A. According to Mr Ohm, running 24v should only draw 0.4A :slightly_smiling_face:

Do you mean the hotend PCB boards on the K1 and Ender 3 V3 are the same?

The pictures above show that the fans are not the same and have different serials and draw different amps.

Can you please send this stl my fan shroud is cracked and held together with super glue my discord is hi.x3 if you need a different platform please tell me im desperate to have a replacement lol, thanks
