WINSINN 50mm 5015 Blower Fan 12V, 3D Printer 12 Volt Fans Blower Turbine Turbo Hydraulic Bearing, Brushless Cooling 50mmx15mm 2PIN (Pack of 4Pcs)

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.

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

These fans work fine, but for 3D printing where the print head moves rather fast the motor shafts have too much play in them, resulting in some clicks when it's moving. They get underclocked to run at 40% to provide the same cooling levels as the 4015s it replaces, so they're nice and quiet when the machine is cooling down. The clicking noise is driving me crazy though.

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!

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.

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.

These fans push a lot of air, so much so that i have to limit the power to 50% or my nozzle would cool down too much. But be aware that these bearings allow the fans to move up and down within the enclosure, creating a rattle. Otherwise they’re super great

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!

Winsinn makes really good stuff. I believe they are the best fans you can get before entering in to the expensive high end brands. But compared to GDStime that many recommended, I really can't see any difference, both comes with liquid bearing or ball bearings, your choice - ball bearings longer life span but maybe louder. Winnsin push a tiny bit more air so I don't see any reason why go with any other brand consider the value/price. So I recommend all of their fans.

they really BLOW

I tested only one so far, others are spare. Works great. Edit after futher testing : I have compared it to others fan of same size with respect to flow and static pressure. This blower is indeed the quietest but provides the lesser flow and pressure. I recommend it only if you need low noise and that you dont need big airflow performance. For 3D printer, if the airflow is not too much restricted and the fan not too far from the object to cool, it is totally fine. Direct blow without fancy air duct is best. In my application where i need the airflow pushed though a filter, this blower is too weak so i will use others.
