Please do not use, the cooling is 0, it just does not work because it blows against a wall and is thrown back

The internal air path you’ve made just blows it against a flat surface opposite the fan so not much pressure would come out the nozzle

Thank you for this. I have one question and concern. I notice that the 12v quiet fan is stepped down with a buck converter but since this is a parts cooling fan, the speed is controlled by the gcode and software. For example, in Cura you can change the fan speed from 100% to whatever. Can you still control speed through a buck converter?

Hello,

I've only ever ran my fan at 100%. However, I tested the voltage output of the buck converter at various speed settings, and the voltage output at the buck converter does drop with lower fan speed settings.
For example, I have the buck converter set to output 12.05V at 100% speed. When I set the fan speed to 50%, the buck converter was outputting about 5.8V. While this is not a perfect drop of 50% voltage, I believe it is close enough . Of course wyou will need to play around with speed settings to get the exact levels that you want.

Hey, I just installed this with the exact same noctua fan and the amount of air flowing is really really low. Did you also get low air? I'm thinking of making a version for the 60mm noctua fan

I have printed with this solution for 3 month now and not having any problems. I used my "own" design, just putting to designs together.

Any chance you can share yours? I wonder if it makes sense to angle the fan more

You might not have printed something that actually needs the cooling. If you compare the amount of air coming out the bottom with what you would get using a blower fan it's not even close. Axial fans don't work too well for this application.

What's that white guide you have on the right side?

That my printer light. It's an IKEA LED bulb. The light it coming out from the duct.

I'm using your parts cooler to print a 60x60mm to 4020 blower adapter version that my wife just made for me today. Hoping to get a bit more airflow.

How did the 60x60 version go?

I'm printing this and was about to install but then I realized that the part cooling fan is speed controlled and by adding the buck converter you are likely losing this ability, if so I don't think this mod is a good idea.

Never thought of that. As Only been printing PLA and occasionally PETG, I've only ever needed the fan at either 100% or OFF. The spped control wouldn't have been a problem.

Thanks for this.
I would suggest angling the fan towards the outlet. These fans dont like back pressure that much and you would be running the fan much higher speeds to get the same cooling as opposed to lower speeds that would be possible with the fan angled towards the outlet.

I tried that first, but putting the fan in that orientation caused the fan or housing to impact against the right hand side gantry bolts unless it were angled extreamly shallow to the point of being utterly useless.

I see. thanks :-) .

Will this work for a CR-10S?

Don't know. It might,but looking at photos of a cr10s, it looks like the duct of the shroud would sit below the nozzle.

Very nice. What material did you use?

Photos shown are in PLA as that's what I was testing in to get everything fitting proper. But I will be printing the final part in PETG.
