Amazing fans

Super powerful fans! I was unaware that these style of fans could create such good pressure for their small size. Running them at 60% on my 3D printer is almost too much and you could easily get away with just one for part cooling if needed. I did have issues with an annoying whine if used at any speed below 100%. I was able to fix the whine by enabling Software PWM in my firmware.

Can have speed set by CR-10 / Octoprint. Quiet, too!

After picking up these: https://smile.amazon.com/gp/product/B01N6Z3L7G I found that they will not let their speed be set by the CR-10 or Octoprint without a 220uf cap - which worked, but made a faint screeching noise. THESE, however are *much* quieter, put out some air and can vary their speed when I slide the fan control on Octoprint. I'm much happier with these.

Very quiet. much quieter then stock cr-10s.

To anyone who is looking to replace your cr-10s part cooling fan. These are basically plug and play. You are going to have to change your connector but other then that it will work as a direct replacement. Or if you have a V2.1 control board you can add 2. I know the board in the pick is not the same color as the green one but the fan outputs are in the same spot. there are 3. One is for your hot end. the other 2 can be used as part cooling fans. Very quiet and seem to be decent quality. I would buy again and maybe will for my prusa i3 mk3 clone.

A surprising volume of air

I got these to augment the airflow for my RV compressor fridge. In the now common excessive heat, it got too hot and shut off. The muffin fan on the compressor is not sufficient to pull the air through. I wired both these fans to a switch and no matter how hot, the fridge stayed on. Cut the temperature over the compressor by 20F measured by my temp gun. They are quiet too. I got a temperature switch to wire in but I haven't done that yet.

Perfect for Fan Speed controlled 3D printing

Perfect for Fan Speed controlled 3D printing. These fans allow setting fan speed in slicer software or 3D printer control panel. There is a bit of an annoying whine at lower speeds but it is usually drowned out by noise from other fans or stepper motors.

So Far So Good!

Powerful little fans. 6v is good, 9v is probably the sweet spot, 12v is crazy lol. They push tons of air. Some double stick thermal tape and a thermostat relay module later, my mppt solar charge controller can be actively cooled quietly without tripping any thermal protections so I can push it near it's full load all day.

Awesome radial blower for my CR-10s.

Perfect fit for my CR-10s after printing a fang mount. Tested it conducted several bridging test, worked better than expected.

Great. Quiet

Great. Quiet. Reliable. I would like to mention that I replaced the original fan on my Anet A8 with this and this fan works much better.

Great 3D printer cooling fan.

Replaced the cooling fan on my FLSUN Kossel Mini. These fans put out so much air I had to re-design the fan shroud on the effector because the fan was cooling off the heat block and causing a thermal runaway. Good fans, quiet and move a lot of air. My goto cooling fan for printer builds.

Exactly what I need for my 3D printer

First off - the cable is NOT long enough for an Original Prusa. I had to cut off the connector and solder it to the existing wires. I had a friend make me an adapter cable before the original one got too short to use. These fans are reliable and quiet. They give good airflow and are consistent. That's as much as you can ever expect from fans. I've had to replace them because I mount my fans at a 45 degree angle which causes the bearings to wear out faster. This is no reflection on this product. It's a known result of the angled mount. One suggestion is to put a drop of paint or nail polish on the indent of the fan hub. That makes it very easy to see if the fan is spinning or not.
