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 feedback about the poor quality fans both in the power supply and in the exhaust port of the enclosure. I haven’t installed the 3D print module yet and bet that one is also cheap and loud. I work in an 18x12 home office with wife and she thought the street cleaner was parked outside of our street-side apartment. It surprised me that they cut these corners yet spent a billion years designing Apple-esk packaging and assembly booklets. A $2000+ printer and enclosure and $0.50 fan? I don’t get it.
Unfortunately, you’re just seeing the first of many such allocations: lots of effort making appearances look slick, insufficient effort making a real quality product.
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!
PS now I have 4 more 3510 fans… do you know if we can replace some other original fan? What about the fans inside the 3D Module?
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.
Auch!
Do you think it would be better to get back to the original one? Can you please keep us informed on any news? I just don’t want to burn or break my little Snap!
I mean don’t throw the original away, it’s a functional fan, just insanely loud.
To be honest I think I bumped the fan a bit hard before installing and it caused a loud rattle so I replaced it. It wasn’t a catastrophic failure though.
Maybe the hydraulic bearings are a bit more fragile than I’m used to.
A little teflon lube (I had some for bike chains laying around) in the door groove helps the slide. And tabs on the part you want to hinge ‘out’.
I’m with you on the fan though - noisy as heck. Haven’t tried swapping mine yet, waiting until warranty expires to be “safe” they don’t give me any guff should I have other issues. (So far I’ve had great success printing, almost everything has been fine except an inability to get ABS to stick to their plate so far so I’ve stuck to PLA. A couple initial successes with lasering although the camera align mode has been garbage for me. Haven’t tried and probably won’t anytime soon the CNC as this is an indoor machine and I don’t want the mess…)
Hi guys, and hi @brent113,
it’s some days that I’m using the fan you suggested and it seems to works very well but… sometimes when I switch on my Snap I can hear some kind of “rattle” from the new fan!
The “rattle” disappear after less than a minute so it seems like the fan has to warm up.
Any idea? Is it normal?
I have just ordere the same fan. Hopefully it will bring the noise down. Also i’m considering to create a silencer based on the same princips as used i ventilation system. I have printed one, that fits over the house and sits in front on the fan. It helps but not enough.
