It has much higher air flow than was expecting. I installed a all metal hotend on my Ender 7 and have no fear of heat creep with this fan. It is also quieter than all the other stock fans on the printer.The amount of air these 40x40 fans move, is surprising.Any time airflow is high, the noise created will also increase. Although, there are ways to design the fan blades to keep noise to a minimum. I see people praising the Noctua fans, I tried one and was not too impressed (except about the price tag), yes they run quite, but also have a lower air pressure. In 3D printer builds, the Hot-end assembly needs to be cooled properly, otherwise you'll get heat creep. I am fortunate enough, not to sleep in the same room as my printer are. Noise is not too much of a concern. Since the fans I am reviewing move the appropriate amount of air for my application, I always would prefer airflow. Yes, you get a few more ding dads with the noctua, in the end the cheaper Chinese made (noctua has probably outsourced their product too) fans here, will push about 2 CFM more than the noctua of the same size. Noctua doesn't even tell, until you search for the CFM rating.Did exactly what I wanted it to do.I was having problems with my 3d printer. First, clogging caused by the original fan suddenly stopping to work. Took me a while to figure that. In the process, I started printing without the silicone sleeve for the hot end. When I finally replaced the fan, hot end temperature could not stay constant because there's so much flow from this little fan, and that would make the printer to stop printing. Since I lost the sleeve, interim solution is to cover part of the fan inlet with tape to decrease air flow and keep temperature steady.So my take out is: This fan works quite well, but for your printer to work, make sure everything is assembled as should. It also seems more silent than the Creality OEM.These fit in the Ender 3.These feel like they flow just as much as the original Creality brand.They are quiet at first. Much Quieter. Sadly one little nick of the fan blades and it over.I was testing out the motor and I accidentally hit the blades with my screwdriver and it got noisy. There was nothing I could do to make it quiet again. It's ok I bought two, but once again I hit the blades now I am back to a noisy fan.Still an improvement over stock, but nothing like the youtube videos. The housing adds sound to the system as well. Overall its a tad bit quieter with less high pitch whine, honestly is my biggest complaint.Wired wrong for my application, but a fairly simple fix. Works.I got them because they were rally cheap I wanted a small fan that would rest on top of the All in One PC to cool the base that has the MoBo.Its not stable as its v small, keep that in mind. I will need to glue it to a small wooden base to keep it steady.IF you want to use it in a cabinet or for a Home theater, I would say go for a larger one as in 3" or 4".There is some noise (not that bad) due to it being on the base but once I glue it to a wooden base it should get quiet.I bought this to replace the stock fan on my Ender 3d printer....and ever since replacing my stock fan, I am getting thermal errors because the hot end will not heat up fast enough.....it works TOO well at cooling the hot end...which I guess means this fan really works well....I will have to adjust my thermal settings for its use.Great price very quiet I only wish they would offer a mother board connection version because that is why I bought it in the first place, but it still worked great.The items appear fine but I'm deducting points because the package was already opened (see attached image).A little tinier than expectedDidnt really read on how small these actually are. They are small. LolBought them to cool a modem both fans don’t Have the CFM to do the job
