Hello everyone,

I’m asking the Lemmy: I’ve been the owner of an Ender 3V3 SE since Christmas and am quite happy with the printer so far. The price/performance ratio is good. Minutes. Only the fan noise when you turn on the printer and preheat it for the first 5 minutes worries me. It doesn’t sound healthy. In my opinion, it’s both fans, first the power supply, and when you preheat PLA, the hot end fan as well. When I print, everything sounds as it should.

I’ve included a few video links:

Power supply:

Then I preheat for PLA:

I’m curious to hear what you think.

Best regards,

Patric

    I don’t think those fans are bad, just noisy. And noisy fans are a thing for a lot of less expensive brands. They tend to use sleeve bearings rather than more costly ball bearings and the fan designs can be not optimized for quiet operation.

    I would keep using the printer and monitor the sounds of the fans. If it gets louder or odd new noises appear then something needs to be done. I would recommend starting to look for fan mods for this printer. I’m sure there are some out there. Ender printers have a very active user base for modifications and help.

      There are absolutely fan mods for that model. I used to have one modded because of the power supply fan is insanely loud when warming up
