Anyone know which sunon fan would be suitable for replacement?, or any other quiet fan?
I did the fix here, so now my fan also shuts off when printer is not in use, but it's very noisy when printing.


And I realy hope Raise3D will make the fan controllable through g-code or something, so It can be enabled when we print with filaments that need it to be used, not all the time.

I'd give a noctua fan a shot.

Yeah :), was hoping for an model number for direct replacement though :) *lazy*

Noctua NF-R8-redux-1800 is only 17.1dB but still pushes 31CFM, which is good enough. I'd guess from listening that the crappy stock fan is easily in the 35dB range and up, which is several orders louder than the Noctua (dB is not linear, so 34dB would be much more than 2x as loud as 17dB, for example)

But none of the noctuas are actually plug and play because they have speed control leads and are 4 pin, while the E2 is using a crappy, cheap, loud, no-name fan (JXF8025S12H) that only has 2 power only leads. So you need to use a 4-2 adapter or whip out your soldering iron and shrink tubing then cut off the extra leads and manually connect it to a 2 pin connector to make a better fan work.

Ok, I found that model in two variants, one PWM and one non PWM, the PWM one have 4 leads, and the non-pwm have three leads.
So the three pin one would be best then, since hte third lead is just rpm speed readout, whereas the 4pin have pwm signal also.
Will look into that one, thanks!
