WINSINN 50mm 5015 Blower Fan 24V, 3D Printer 24 Volt Fans Blower Turbine Turbo Hydraulic Bearing, Brushless Cooling 50mmx15mm 2PIN (Pack of 4Pcs)

This fan is a compact and efficient cooling solution suitable for various electronic and industrial applications. Its 50mm size makes it ideal for tight spaces, while the 5015 model ensures a good balance of airflow and quiet operation. The 24V power supply offers reliable performance, and the fan's build quality appears durable for long-term use.

Size as purchased, power and airflow seemed reasonable. Not quiet, but not noisy.

The WINSINN 50mm 5015 Blower Fan works perfectly for my 3D printer. It’s quiet, powerful, and provides excellent cooling. Easy to install and very reliable—exactly what I needed to improve print quality.

I wanted to upgrade the hot end cooling for my 3D printer and needed to pick up a 5015 style fan to accommodate the setup I have on my Creality Ender 3. I did not want to blow the bank, but I did not want to go super cheap either as this was a test. I picked these up with some slight trepidation because the reviews are all over the place. First off, the installation and wiring were incredibly easy. Secondly, these do a great job of cooling and have variable speed control, so there are no concerns there. Third, they are much better and quieter than the factory hot end cooler that comes with the printer. The only downside to these is that when the fans are blowing at full speed for awhile, I notice that they do rattle a bit, which can be annoying. It is not consistent so you cannot just tune it out as the rattling is intermittent. For the price of these I should not be surprised and I have not tried swapping it out with any of the others as it is not consistent enough that I have need to do so. I may wind up upgrading to a higher end fan eventually, but for what I am doing and for experimentation, you cannot be the costs.

I replaced the stock blower fans on my Creality Ender 3 V3 KE with these WINSINN fans, and the difference is remarkable! They are significantly quieter than the original fans, making a huge improvement to the overall printing experience. The airflow is also noticeably better – I needed to update the First Layer Bed Temperature to a higher setting to ensure proper part adhesion. Installation required a bit of modification; I had to cut off the existing connector on each fan and solder on the connector from my existing fans. Since I only needed two, it’s great to have the other two as spares at such a low cost. Highly recommended for a quieter and more effective cooling system!

these are the cheapest u can get an its always what i buy to have spar fans around for my printers an other electronics. the down side is pretty much everytime i buy them i get a 4 pack an ive always had at least 1 or 2 of them, ive even had all 4 fans have wires that was loose from the solder points keeping them from working, sometimes its just the wires broke loose or poor soldering then theres the more common issue where its not the wire and instead its the solder pad ripped loose from the little electronic board so those fans are trash an go in the trash brand new. i can say if u get a good one or if its one that u can solder the wires back together on they do seem to last. i cant remember having to replace a fan that ive replaced with one of these so they seem to hold up better than the original fans that come in chinese brand 3d printers. but if u dont want to deal with doa fans, spend more money an get a higher quality fan. also i can't say how bad they are for noise cause i have so much ambient noise going on a fan is the last thing i'll heard unless its screaming but i also keep my printers in enclosures so the sounds for them are mostly muffled out an if i do hear anything its usually the noisy a4988 steppers from my older printers so its about half an half silent steppers vs a4988 so fan noise was never really a concern for me but for those who do want to know about this, if u want silent fans buy noctua, if u dont mind tinkering buy these cheapos.

The product is fine. I'm using it to cool a voltage boost regulator. The only thing I disk my like was they were all tied up together. The connector doesn't make it easy. It took more took time releasing the knot than scissors soldering it.

Works amazing for my replacement print fan for my modded Creality Ender 3 S1 Plus and modded Creality CR 10 Max. It is a little bit noisy, but that is to be expected with a high volume fan like this.

great little fans. i installed these in our RV fridge and i works great for excess condensation.

Used as a part cooling fan in FDM printer. Great airflow - not too noisy - however if the rotor is blocked from turning by a bit of debris, or if the fan air output is blocked, the unit will overheat to the point of melting the fan housing. Also if running with a ambient temperature over 40C under load the fan will suffer damage (rear of housing melts). Power is 3 watts at 24V

Achetés pour remplacer les ventilateurs d'origines de mon imprimante 3D je suis bluffé car ils sont hyper silencieux et je trouve qu'ils soufflent très fort donc attention à vos réglages. Je recommande!

Ich benutze diese Lüfter zur Bauteilkühlung am 3D-Drucker. Nachdem mein alter Lüfter, der einzeln so teuer war wie diese vier zusammen, nach knapp50 Betriebsstunden nicht mehr funktionierte, bestellte ich diese. Zwei Punkte haben mich völlig überrascht, nämlich wie leise der Lüfter ist - man hört ihn fast nicht - und wie gut er ansteuerbar ist. Er nimmt seine Tätigkeit bereits bei 10% Lüfterleistung auf. Das hat der vorherige auch nicht geschafft. Der schaltete sich erst bei 22% ein. Das frühe Einschalten bei niedriger Leistung ist aber für verschiedene Filamente wichtig. Der Luftdurchsatz scheint ähnlich zu sein, aber dazu kann ich nichts genaues sagen. Auch zur Haltbarkeit kann ich keine Aussage machen. Bis jetzt bin ich jedenfalls sehr zufrieden damit und wenn er nur halb so lange hält wie mein alter, dann habe ich immer noch gewonnen.

El ventilador funciona a la perfección en mi impresora Prusa I3, el cambio fue limpio, lo único malo fue que el largo del cable es muy corto (ya sabía sobre ese detalle desde antes de comprarlo), pero nada que unos cables bien soldados no pueden arreglar. Leí muchos comentarios sobre el ruido pero la verdad no estoy de acuerdo con ninguno de ellos, el ventilador no hace ruido en exceso, cuando imprimo no se percibe. Excelente, volvería a comprarlo.
