But the fan is mounted vertically on stock Prusa Mini, what's the benefit?

This is the MK3 section; I thought that's what we were talking about.

RE: Prusa radial fan (filament cooler) - better replacement

You're totally right, sorry for the confusion!
My mistake

RE: Prusa radial fan (filament cooler) - better replacement

So, another year past, and i have used about 4 prusa-fans.
I decided to go "china" awhile ago and purchased a fysetc fan, which is now in use, since my last prusa fan was broken again.
I took the time to open it up and have a look inside:

As i suspected: a sleeve "bearing" (not an actual bearing). Which is the cheapest of the cheapest.
I now ordered a few from china, which supposed to have real dual bearings, which will take some time to get here (tempted to open one up)
I also ordered some LDO's, which will be sent in a couple of weeks.
And i ordered 2 Sunon fans, which are hard to find and don't have enough punch, but will take a chance, since the fysetc is also not really a power king.

Maybe i'll order some more original prusa fans, but.... 

Anyone else found good ones?

RE: Prusa radial fan (filament cooler) - better replacement

Please keep us up to date! I'll also buy some of aliexpress..

So sad that nocuta does not make any of them.

RE: Prusa radial fan (filament cooler) - better replacement

Update:

I finally found some that are actually INSANELY good. Well, my order is prestine and perfect! No rattle at all.

They are from FYSTEC (Modelnumber: 05B5015H - Ball Bearing)
DC5V with 0.35A

And pretty cheap!
Quality is from another world.

Compared the original prusa one with mine from aliexpress and the latter one is alot more powerful.

RE:

The LDO are actually quite good. They have real bearings and blow alot of air.

However, they are loud!
And very hard to get here. 

I now use some cheap chinese ones (Pengda) which seem to work fine.
I will order some of those Fysetc, this time with bearings.

I expected the most from the Sunons, but they don't blow enough air, and rattle when moving sideways.

RE: Prusa radial fan (filament cooler) - better replacement

Got this Fysetc installed and they're good!
However, they spin alot faster and make quite some noise. I now print at 70% fanspeed, which seems to work fine.

RE: Prusa radial fan (filament cooler) - better replacement

Do you have the Serial number for the LDO  or any shop to purchase?    ALL my mk3s+ original fans  are rattling  like crazy,  I can´t anymore with them.   
I tryed oil them ....  no luck.  

Thanks!!!

RE: Prusa radial fan (filament cooler) - better replacement

For the LDO fan just google "LDO DF5015H05S". I found severals shops on different continents where orders can be placed.

RE: Prusa radial fan (filament cooler) - better replacement

Thanks a lot,  im going to check them again.  

RE: Prusa radial fan (filament cooler) - better replacement

The only shop I found in Europe is located at Germany.  It seems they dont ship to Spain.  

I will try the "bearing double fan"  from Fysetc,   it seems to be really hard to purchase the LDO version.   

I dont understand why prusa uses non bearing fans,  and even worse,  at 45º in mk3s+  ..... They rattle cause of this   (github is full of people with this issue in  mk3s)

There is a "delta-p" STL Fan Shroud to install the fan vertically,  but  it has worst perfonfance than original fan shroud.....  so it sucks in overhangs.....

RE: Prusa radial fan (filament cooler) - better replacement

I am located in Germany, so I had low shipping cost. I found www.jacksfilament.com ships world wide, so I am sure theay also will ship within EU. Good luck.

RE:

Thanks,  but that the shop I was telling about......  they dont ship to spain.    I will try to contact them.      (when you are purchasing,  the shopping cart tell you that your location do not have any currier,  so it can be shipped)....... 

This is the only shop I found inside europe.  

From EEUU you can Import,  but we have 25$ custom top  including the 10-14$ shipping cost......  (at least to import from EEUU) .... it´s nosense  the Custom Taxes in Spain.
