Hi there,
Are there any suggestions on how to reduce the noise of the fans?
I thought about buying Noctua fans but those are 12V, not 24V. The minimum size of those are also 40mm, which is good for the main fan but too big for the hotend fans (30mm) which are very loud, too.
Best regards
Fabian
You could look at placing dampers between the fan and the mounts, or printing mounts in flexible TPU filament.
I wish I had a working 3D printer... :-P
I’m also very disappointed about the high level of fan noise, specially the PS and control board fans. I have an older printer, dead quiet until it starts printing. Can we get the specs of these two fans?
Maybe something like this would be cool:
The PS use a 60mm fan, case a 40mm, hotend 30mm and print cooling are 50mm blower fan.
All are 24V.
You can pick anything with same size and voltage, but is not easy to find quieter ones.
You can also use 12v fan but need to add something to reduce voltage (or having fan in series).
Noctua made the most quiet 40 and 60mm fan, but both 12v (i'm planning to add them, since i have it from my previous printer).
The best are:
Noctua NF-A4x20 FLX, for the case
Noctua NF-A6x25 FLX, for the PSU
Noctua NF-A4x10 FLX, i think this could be used for the hot end, but you have to print a new support to attach them.
Again these are only 5v or 12v fan, if you use them directly on a 24v power supply you will destroy them, and don't use different fan in series :)
The blower fan are the hard part, you will find lot of online store claiming to have the most silent one, but they are almost all the same, someone say Sunon make silent blower fan, but i haven't tried one (you can also check , keep in mind that low Air Flow mean less cooling).
Thanks, will look into those. Not worried about the part cooling blowers, I print petg, they are rarely turned on.
@dar.flem Noise level are 18 dBA for the A4x10, 15 for A4x20 and 20 for A6x25, they are very quiet. Sold at 12-15€ on Amazon. I'm waiting for to install them.
Also fans comes with "Low-Noise Adaptor"it reduce rpm, so noise (but also air flow)
For even more silent setup you can use A4x20 on the hot end too, but they are a bit bulkier.
@Andrea ordered! Spouse hates any noise ;-)
