WINSINN 50Mm Fan 5V, 3D Printer Micro 5 Volt Fans 5010 Hydraulic Bearing, Brushless Cooling 50Mmx10Mm 2PIN (Pack Of 5Pcs) Review

I only needed one of these to replace a fan that was worn down on my 3D printer. I really didn't feel like I needed more than one but it's one of the only things I've had to replace before so I'm sure I will use them in time. The fact is however that the cost of these 4 fans was less than what it cost for one from the maker of my printer. Great value!

Well you know what they say! you get what you pay for!. The fans work after you re-solder the wires, every single one had cold solder joins or where not solder at all. Also the sleeve bearing is of a very poor quality, after 10 minutes of running time the fans started making all kinds of loud noises and vibrations. I will not purchase anymore nor I will suggest this product to anyone.

I put one fan in and it lasted one day and became so noisy I heard it upstairs and at the other end of the house. The bearings went bad right away.Put the second fan in and it started out loud. They say they’re quiet, but they are definitely not quiet. That one lasted a little over one day and then the bearings went bad on that one.I put the third one in and it was loud as well, but I needed to run the printer anyway until a different brand fan came in. I had bought this brand in the past and…

The fans are very quiet but they do not move enough air. If the RPMs would go a bit higher these would work better but then they would be louder. Ideally they would let it spin faster and then I could decide on the speed or noise that I wanted with a PWM controller.

I bought these for my Tevo Tornado, who's 50mm fans went out. These are fantastic, low nice, great air flow. Keeps my control box for my printer nice and cool.

These were bought for use with a custom 3D printer. Although they take a little time to ramp up to their full speed, they're very functional and surprisingly quiet.

I bought these fans to use one to replace the dead fan in a cheap, Ebay bought smart charger. The smart charger has lasted over 3 years now, two of those years in constant use and only the fan has been a problem. Ive come to like the little cheapo charger so figured Id keep on using it if all I have to do is replace a fan. I doubt these fans will last any longer than the one that was in the charger to start with but you get five of these fans for very little money. Even if they only last a year

Needed these for a project and they fit what I needed. The only critique I have is that some of the fans have a strange static sounding rattle to them (ran at 12v must test with 24 and leave on to see if it goes away). This even after I put some light lubricant on it. If you have multiple components going, you probably couldn't hear it unless up close but if you have quiet components, you will definitely hear these odd sounds. They do move air however. One thing I will say is if you experience…

These sure blow air well but they are much noisier than the description implies. They are actually noisier than the stock fan they were supposed to replace.

only use for one month and fan fail to turn I bough 5, replace one every month, one fan last only one month. This Brushless Cooling fan is prone to catching fire or causing other safety hazards if not used properly.

So far everything is as expected with these! Came well packaged, were able to be installed easily in an Aquarium hood. They're definitely quiet but they don't have too much power it seems. Although they should be venting enough for my purposes! I'll update later when I know!
