So It seems like the original 5015 part cooling fan was this,
But now it seems to be this one in the X1C/X1E/P1S, and maybe all newer printers.
Which one is better?
Has anyone tested them, RPM, CFM, mmH2O?
My 0.15amp seems to be around 9500RPM but that’s all I can say.
Is the 0.22amp newer one just different, an improvement, or a cheaper downgrade?
If I order a new toolhead cover, which fan will come with it?
Yes a toolhead cover will come with one.
I can’t answer your other questions but if you decide to dyi you’ll have to splice the connector onto the new fan.
If I were a betting man, I’d look for a replacement that matches specs of the original.
Or just drop the $19 for a new cover.
So I ordered another toohead cover, it came with the 0.22amp Snowfan, I compared the two fans with these instruments (+ a cellphone dB app, held at the door of the printer) here’s the results, maybe 7 percent better, and 8dB quieter.
Since I’m looking for better part cooling and thought this was an interesting topic, I… got nerd sniped and now I want a great part cooling fan…
However I’m confused by, what I suspect is mostly false marketing or for other reasons, huge differences:
Is there a typo in the nevermore? Or can the differences be this huge? And or is CFM not the best metric to assume cooling capabilities?
Could be the way they calculated the CFM might be different. (I wouldn’t swear my testing to be exactly correct, but I feel the general percent comparison of the two Bambu fans is mostly accurate)
Fabreeko’s numbers are the same as the 3DO ones, Honeybadgers
I’m guessing they would be very similar in perfomance, given the similar amps and pressure numbers.
For cooling, my understanding is that we need to transfer heat from ‘hot thing’ to air molecules, so more CFM should gererally mean more cooling up until something else in the system is the limiting factor, like innefficient heat transfer from the thing to the air, no matter how much air passes over it.
I think they are rated at 5.36 CFM, which is the value i find the most, if that’s any indicator. Harder to get in Europe though.
In regards to the Snowfan;
Another fan worth considering:
