Hello, Why is the fan of the power module so loud/making noise from power up (fan 100%?)? That small fan makes a lot of noise as soon as the power switch is turned on. Is there no temperature controlled fan possible? I like to change the fan for a Papst, Zalman or other brand with bigger size bu…

Yes, why is it so loud ?? I received the printer in september 2020 with the loud fan, so till now, nothing is fixed. After the waranty periode, i will replace the fan.

[image] DTW: SM2 A150 this week. On the power modul i noticte the loud noise of the back fan, so i teardown the hole module, and found a MeanWell powersupply for 24V and 320W 13,4A with a build in Fan and some additional boards from Snapmaker. Then i see a big problem, the light distributor scre…

I recently watched the video of the live stream from 04.June.2019. [Snapmaker 2.0 Live Stream] I guess they ran into temperature issues of the powersupply or bad capacitors after a time, so they hastily placed a fan inside the psu to start mass production or something else. In the video…

@brent113 . The 3510 fan swapout is a very nice noise reduction for very little effort!

The noctua 40x40x20 comes with LNA and ULNA in-line resistors. There’s no need for buck converters, etc. At 50mA, the resistors only have to burn off about 1/2 W. Even a simply metal film resistor can handle around 3W. I just finished assembling the A350 and enclosure. I sent them my negative feedb…

[image] naesmac: It surprised me that they cut these corners yet spent a billion years designing Apple-esk packaging and assembly booklets. Unfortunately, you’re just seeing the first of many such allocations: lots of effort making appearances look slick, insufficient effort making a real qua…

Sigh. What other major showstoppers haven’t I come across yet? I’m already not happy with enclosure doors.

Just swapped the original power module fan with the 3510 suggested by brent113… great improvement! About 8/10db quieter and the new one looks pretty identical to the original one. Hope the air flow is the same to non have any issue. Big thanks to brent113! :slight_smile: PS now I have 4 more 3510 …

The link above Franky posted has all the fan information. Like every fan is different unfortunately. I had a replacement fan failure, so keep them handy - they are cheap, and not in the good way.
