The fan of the power supply is extremly loud. Louder than the complete Snapmaker A350. Does anybody chanded the original fan to another fan ? Or is there any possibility to get the fan quiet durig coolng ? regards K.D.

Thank you for the answer. I’ll try it. K.D.

By the way … what voltage has the fan ? 5V, 12V or 24 V ? regards K.D.

Further down in the linked thread there is a post with more details on each including voltage. If I recall, they were all 24v.

Hi, I have the same problem. My solution : https://www.thingiverse.com/thing:4612722 Best regards

My solution was to replace the built in case fan with a quieter one from Amazon. I went with a 5 pack because I can use the rest around in projects, I got these: [image] Amazon.com: WINSINN 35mm Fan 24V Hydraulic Bearing Brushless 3510 35x10mm - High... Buy WINSINN 35mm Fan 24V Hydrauli…

Thank you for sharing the thingiverse model! I purchased wrong (size and voltage) fan by getting the enclosure fan (8025s24v2p2.5 .1A, Wathai brushless, 40cfm, 27dBA) thinking it was the 2nd internal PSU fan (6010 12V.13A, NMB 2404KL-04W-B30) ). I’ll see if I can modify your case to fit the 8025 …

Has anyone tried just reversing the fan so it blows air instead of sucks air, that way the noisy exhaust of it would be dampened by the obstacles in the power supply.

give it a whirl if youd like its a relatively simple mod to accomplish in either case

Another solution would be to insert a low ohm resistor. A small reduction in speed should produce an important decrease in noise. Did someone try this before?
