mk3s+ to mk4s upgrade, sounds like a vacuum cleaner
I just upgraded my mk3s+ to the mk4s with the upgrade kit (went pretty smoothly, apart from a hitch where I had to pick some m3 12mm screws and nuts from the old printer, like many other upgraders I noticed in the comments)
First print was the bonkers benchy from the usb stick (OK, maybe not the best choice for first print 😉 but it went great)
I've since placed the printer back to where the previous version was standing. I notice it makes way more noise than the mk3s+, it seems to be the turbo fan on the new extruder carriage. It sounds like a vacuum cleaner. My phone's app measured a sound pressure of about 68dB at 20cm from the printer during printing of another benchy (not the bonkers version). Doesn't matter if I use the one included on the stick or sliced by my own settings in prusaslicer 2.8.1.
Could this be a problem fan or is it just way more noisy than the old setup? It's also much more noisy than the mk4 at work (which is going to be upgraded at some point).
Based on the mk4 at work I thought the upgrade was a good idea, but I'm not so happy with this new wall of sound 🙁
Are there ways to reduce the noise without impacting printing quality or speed? (I'm sure lowering fan speed would help with the noise, but it's probably at this setting for a reason...)
Cheers

RE: mk3s+ to mk4s upgrade, sounds like a vacuum cleaner
The fan on my MK4s is also loud, but only when printing overhangs or when needed for layers that print very fast.
When it runs at higher speeds to support these challenging printing conditions its definably louder, but sounds like fan and not a vacuum. I can hear it in another room through 2 walls but only for certain scenarios.
When printing at higher flowrates, small layer printer times, and overhangs, the higher flowrate this fan offers seems to be beneficial.
You can change the fan speeds in you slicer, but the fan will always be noisier than the older fan because it is moving a higher volume of air. And so far the improved quality of overhangs makes it worth it for me.

I read this review on Tomshardware that the printer is so quiet it can be used in an office environment (I'm assuming with normal hearing people in it 😉 )
The noise on my upgraded printer is continuously loud during the entire print of the benchy model. Definitely not suitable for an office environment. At work, where the printer is in the next room, it may be ok, but then we'd have to keep the door closed if it was this loud.
I really think the part I received is not quite right...
RE:
My experience is a little better, in that many of my prints do not cause the fan speed to increase above about 40%. Under those conditions, while I can still hear the fan while I'm in the room, it would not be distracting. There is no question that the fan on the MK4s is louder but unless I'm going for fast speeds, it isn't a down tick for me and it's still the quieter of my three printers.
Question, are you pushing the benchy with the high flow profile? I haven't lo0ked it over yet and now I'm wondering if the print fan performance parameters in that profile are set to meet the need of higher flowrates., with the consequence of more noise.
And I have to admit, I wouldn't try sleeping in that room during print. An who knows maybe your fan is just louder than mine.
Good luck finding a happy place.
