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 have had to replace both fans on that printer more than once.

    Also a loud noise means something is in the fan.

    Your bigger concern is when heat creep destroys your entire heat block and nozzle from auxiliary fan failure.

    Or when part fan doesn’t sufficiently cool the layers so you get a lot of lifting and squishing.

    Keep an eye on those.

    Fyi. The fans are wired backwards. If you replace with official creality parts you are fine. If you don’t. You will have to cut off the connector on the new fan, flip it. And reconnect the wires.

    Also many replacements fans have the wrong size connector too.

    My advice. Just buy official creality ones.

    Also. Always unplug your printer before working on any electronic components. If you don’t. You can destroy the circuit boards.

    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

    I had the same issue on my E3V3 KE, the 3510 fan had a hard time spinning (free of debris), ordered a new one and replaced it. Had the same issue in the past with other 4010 fans that Creality uses. I think you had a bad fan to start with.

    TLDR; Replace it
