MakerHawk 40 40 10 Fan 24V Hydraulic Bearing Brushless Cooling Fan RGB LED DC 4010 40x40x10mm 0.05A for 3D Printer, PC, Case, CPU

El producto funciona bien, no son de la mejor calidad pero hacen su trabajo. Si Son silenciososo! pero tomen en cuenta algo que me psao. Los instale en mi impresora 3D para refrigerar la electronica y al prender la maquina sonaban (menos que los de fabrica pero sonaban) hice prubas prendido quitandolo y poniendolo con la mano y me di cuenta que lo que hacia que hiciera ruido era la protección que tenia de la carcasa de la maquina (la que parese rejilla para que no toques el ventilador por aacidente) provoca turbulencia. Pues se la corte y Problema solucionado, ya no sono nada! (tambien recomiendo poner entre el entilador y la base una especie de aomortiguador, puede ser de silicon, caucho, foami, lo que tengan a la mano, yo puse un poco de cinta doble cara de la tipo esponja)

I love the colors and that they change, it tells me the fan is operational and doing its job. Read the warnings in the listing, these should be limited to 10hrs a day and not near heat which will boil off the lubricants. They don't typically just fail, they slow down, so you don't notice they aren't working right. It's hard to diagnose because it's spinning, just not fast enough to cool. Don't get me wrong, I got about 18 months of occasional use out of the one that I just removed. That's not even close to the 40,000 hours listed, but then it's sitting next to a hot end at 215C.Would I buy them again, yep. I love the colors, they are quiet, easy to install. I might consider putting them on a yearly replacement cycle and not wait for them to fail due to the heat and long prints.

Utilisez pour mon imprimante 3d Ender,aurais aimé que les couleurs ne change pas (LED)

Got these to replace the stock fans on my voxelab printer. The first one I hooked up was DOA, lights came on but wouldn't spin. The second one is working great though, and I still have two others for back up. I do love that these fans have very little noise.

My ender 5 fan started making some really crazy sounds. Come to find out a blade had sheared completely off.I'm not one who loves to make crazy printer upgrades but I knew I needed a new fan. I was looking for a stock replacement and happened to see these. Not only does my new fan look amazing with the swirling color lights, but it is completely silent. The best part is with the four pack I have three more ready to go, should it fail.They dont come with any wire connector ends for this tiny gauge of wire so I have an ugly splice and tape job going on right now, until I can figure out the right quick connectors to buy.
