WINSINN Ender 3 Fan Blower 40mm 24V, for Upgrade Ender 3 v2 Pro 3X CR-10S, with Air Guide Parts, Hydraulic Bearing 2PIN 40x10mm 4010 Brushless Turbine Turbo

When upgrading Ender3v2 I used WINSEEN Ender kit and been happy with the results. I upgraded to dual blower so the kit was perfect. Fans are much quieter and move more air than what came with the printer. Working flawlessly for over 2 years.I will be buying more for my new project.This week I have noticed a noise coming from blowers. I'll be contacting the company and update here.

Sitting in the same room with my Ender 3 Pro while it's printing made me realize just how loud the fans are. When my wife asked me to close the door, that told me I needed to do something about it. I read good things about these fans, and they were at a really good price point, so I bought the set -- two regular fans and two blower fans. Since I only needed one of each for the hot end and parts, I used the second fan for the main controller board. These fans are a lot quieter than the stock fans, but they still have a high pitched whine to them the is noticeable, but not as much as the noise level of the stock units. They are a direct fit replacement, but as other reviewers have noted, the wires are not as long as the stock. I just clipped the wires from the stock fans and used a butt connector to join the new fans to the stock leads. Unfortunately, I discovered that the power supply fan actually makes a lot of noise, too, so that will be next on the list of things to upgrade.

I have a ender 3 pro and one of my stock fans started squealing and after a while wasn't spinning at all and almost ruined printer. but using these for replacements this product even feels better made than stock. and i can hear the faint sound that the fans are working it gives me a better peace of mind and trust i can rely on.

The truth of the matter is that when you purchase a 3D printer, one of the things that gets constant wear and tear are fans, since they're always on and working hard in high temperature environments. I ended up using my Ender 3 before an estimated 2,000 hours of runtime (not always on) before replacing them with these since the original fans were grinding and catching during operation, impacting cooling capability significantly to unsafe levels.Ball Bearing fans have a higher tolerance for heat and potentially run longer than the stock fans (of which I believe are sleeved/hydraulic bearings). I expect these to last much longer. Installation required a soldering iron for the print head fans.Even if you don't need them for a 3D printer, get them for some smaller electrical projects instead, as they move a decent amount of air. Good fans, not super quiet but great for their size.

I upgraded to dual blowers, this kit was perfect. Fans are much quieter than the stock fans on Ender 3v2.

I installed one of these fans,turned on 3D printer. NOTHING. Checked the connection, then noticed one of the wires on the fan was not soldered down and just stuck to the label. Looks like it may have been connected at one point. I gave the other wire a tiny (I mean such a small rub on the wire) pull to see if it was attached, just came right off fan. Second blower fan solder points seemed better, but the second fan started making a whining and grinding noise just minutes after it started blower air.Returned for another set from this seller. New set arrived, solder looked OK. Hooked them up and within minutes grinding and vibration noise. These are JUNK. look for a better brand.

My original fans were failing and buzzing so loud you could hear it across the house. These are quieter than the old failing fans, but NOT quieter than the original fans were before they started failing.These are not what i would call quiet fans, especially the side-exit fan (radial fan?). That fan actually has a slight buzzing to it, but because it's a bit of work to replace a fan on the hot end, i'm just going to leave it as is for now, since it still functions.Pros:- comes with the correct plugs for a direct replacement in an Ender 3- regular (linear?) fan is a direct fit replacement for the board cooling fan- correct 24v rating for use with ender 3Cons:- wires are nowhere near long enough to reach the hot end so you will need to extend them- the mounting tabs on the side-exit (radial?) fan are thicker than the original Creality fan's tabs, so i had to shave them down with a razor knife to make it fit in my petsfang part cooling duct. this may not apply to everyone since there are so many options for part cooling (i don't have the original part cooler mount to test with), but i felt it was worth mentioning.- plastic is very brittle (definitely not ABS) so that when i shaved the tabs, it sort of cracked off in chunks, so take your time if you need to modify the fan to fit your application.overall they're OK fans but i wouldn't call them quiet. and no i'm not expecting cheap fans like this to be as quiet as a noctua or whatever expensive fan, but it'd be nice if they were actually quieter than the stock fans (even before the stock ones started going bad)

Purchased these 6 months ago to replace the noisy stock fans on the Ender 3 Pro that lasted less than a month. While not super quiet, they are better than the stock fans. They should last for quite a while because they are ball bearings fans. They are a direct fit but you will have to splice them into the wiring from the stock fans.
