@JvdP : Thanks. I will keep you (and everyone else in this forum) posted.
Yes, its just a Hall switch to commutate (swap polarity) in the windings.
Did anyone ever stick anything in their extruder fan as it turns at speed, break a vane and make it loud like an angry bee?
(Fingers, tweezers... this idiot did them both over the last couple of weeks.)
I vote Project Whisper should contain a solution for that!
Ha. Yes @R Design, I did that over the weekend. I'll be ordering another 30x30 to replace it. I think a half way solution for that would be to print a slatted cover for the fans to try to prevent things getting too close to the vanes. It'll be hard to shut up 30 x 30 fans though. I think the only solution is really bigger fans. It doesn't help that the moulded fan mount snaps and becomes loose. I did notice Richard Horne had his fan held in place with a plastic tie. None of the ties I have to hand is long enough.
I recommend this one: http://www.thingiverse.com/thing:71961
Used it already several times in different sizes.
Great link @Kick2box
Those 30x30mm fans are tricky when it comes to noise, yes. However, a fan shroud will only make matters worse.
I've had E3Dv6's for a while now and although I have fingers and tweezers in there, I've never managed to break a fan blade. It makes me believe that these 24V fans spin faster than the 12v-ones...
Perhaps replacing the fans with 12v versions would reduce the noise while still keeping cooling capabilities?
Do not use the 12v .... tons of problem with them on a V6.
BTW how did you guys mount a larger rumba fan? I feel that that fan can ne made much quitter without the need for any control actually.
@fpex I've had multiple v6's over the years all with 12v fans. I haven't had a single problem.
You can read about a larger rumba fan in my main post.
I must be blind, did you made an adapter for the larger fan?
I haven't cut the frame yet but I'm planning to make a hole the size of the fan and then use a metal fan guard.

I have acrylic, so this is not really an option :-(
Sure it is! I have acrylic too. I will show pictures when my parts arrive and I have done the mod.
Where did this misconception come from that you can't drill acrylic anyways?
From my own fear to drill it!
Do not "drill" it, better "carve" it...
What I wanna say is that you need good and sharp, very sharp, drills and then do it slowly, real slow, slower than slow. Start small, real small. Ok not so small the drill might break, I really hate drilling 1mm or smaller holes in metal...
And then again slowly increase the size of the drill until you have the desired size.
Again rotate slow, that's why I say "carve" not "drill"
Shouldn't be a real problem just need some patience...
Unfortunately there are no real unused parts, if you don't need or wanna use the side cut out then you can do a test with them...
EDIT: oh I forgot: let the drill do the work! Do not push too hard, that's why it needs to be sharp...
Although my expectiations were the same as yours @Alex9779, to be honest I don't agree that it's that bad. The acrylic from the BigBox is really impressive as it's not as brittle as other acrylic types. I've drilled lots of holes (more than 10) of various sizes in the frame now and haven't had a single crack.
I agree strongly with your point of having a sharp drill, I think that has helped a lot. However I have gone pretty rough and quick on some holes as well as pushed the drill and it hasn't been a problem (yet).
30mm extruder fan protector (first attempt - large openings for air + 1cm deep to prevent fingertips....)
- print face down (so the smooth first layer becomes what you look at & any crevices filled);
- just under 0.5mm extrusion width so 1mm and 2mm structures are well mapped;
- turn off gap fill (doesn't add anything and print will go more smoothly);
I think I will order these 50x15 and 60x15 fans
One of them even comes in 10mm if 15mm is pushing it.
You link doesn't lead to any products just to a major page with all electronic component categories.
Are you sure you're going for the small 50mm one? It might still be noisy... The smaller the fan the more noise generally.
