WINSINN DC 25mm Fan 5V 2510 Hydraulic Bearing Brushless Cooling 25mmx10mm 2PIN (Pack of 5Pcs)

Super quiet , plug and play. Correct size. They run 24/7 no problems so far. Quality seems to be good. Should be able to run a thousands of hours and provide great air flow

I purchased these 25mm x 10mm fans for my older Robo3D R1 3D printer. The small hotend fan had been going out for some time making this awful noise when you powered on the printer and then would go away after some time. The old fan was also extremely loud even after the squealing noise went away. I tried the oiling the bearing as you will find on many YouTube videos but the repair was short lived and didn't do away with the loud fan sound. The connector on these fans didn't match mine which I knew when purchasing but removing the female pins from the connector body is relatively easy and I knew I could swap connectors from my old fan to the new one. After connecting everything up and powering on the printer.. Wow what a difference in the noise level, much more quieter and the air flow seems to be the same if not better then the original fan. The fans came in a nice little clear box which is great for keeping the others together if I should need in the future. I can't speak for longevity as I just put one in few minutes ago but at this point I would still recommend them if you need to replace your hotend fan that's dieing. Well worth the small cost in my opinion.

These are extremely quiet and I think you get a great deal for hoe many fans you get. They work great for my applications and for being so small they move a decent amount of air

They come with long power wires, I didn't need them so long but simply cut and soldered to my desired length. It is important to keep the connector on the wire as it is fully crimped and stays on well. If running at alternate speed, the number of fan blades and thier angles will cause varying levels of noise. I ran mine through a TO-90 FET 300ma transistor to make sure I don't blow any channels in the ESP32, very easy to interface. Mounting holes are well aligned (some other fans are not and user needs to adjust the case holes). Noise at full speed is low. Very good seller (lots of variation in product line). Thanks

WINSINN makes nice fans. I've used this with 9 volts and no issues.

They are ok. Quiet - but don't move much air though.

Update: I used the fan as a replacement for the Samsung dishwasher. It's a perfect fit, minus the connector. however it's starting to make noises, not like it was, But still making noises. Its been installed for roughly 69 days.

I mounted one of these fans to cool four 3W LEDs mounted to a heat sink. Fan may be small, but it made a huge difference in how hot the heatsink and LEDs got. I've had two of these fans running 4 hours and seem to have no issues. Quiet and great price too.

Un po rumorose e non velocissime, ma fanno il loro lavoro

Excellent product, quick delivery, good value, but the wrong ends are installed for the V3 KE and SE Ender 3 3d printers (and the leads are very long compared to the factory replacement, so some cutting/soldering is required to get them installed and working and is delicate work as the wire size is much smaller than that installed on these replacements. Still should be a long lasting replacement for the crap from Creality, which only lasts as little as a month.

Le ho usate per raffreddare dei piccoli alimentatori e vanno benissimo

Well the product are ok the bearing’s are nosiey they will need improvements

What a difference! This fan is almost silent. What a relief to get rid of that annoying high pitch wining from the stock fan. So far I only used one of the five fans in the package but they are a must have spares.
