This really sucks
Small but efficurnt

Okay for the price.
Well they work. But on the downside they are reluctant to start at anything less than 50% speed and the wire is only about 300mm long so you will need to splice to existing wire. Is there a printer out there with the control unit that close to the print head?? If you are okay with these minor issues they are fine for the price.

Great little fan
Purchased this to add cooling to a Raspberry Pi case I had printed for an OctoPi configuration. Little bit noisier than I anticipated but fan clearly has god bearings as I think moat of the noise is air rush

They start off well
I bought these for some raspberry pis tht U have in my house. Week one I had to get my ear close to them to hear them. Week two I could just hear them when there was no ambient noise Week three I could hear them over ambient noise. Week four I threw them in the bin because they were louder than my TV. If they are making that much noise they are creating friction so after a month they are starting to destroy themselves. Don't bother.

For the price fairly quite
I run them at 3.3v on Raspberry Pi's I found no need to run them at 5 volts which will make them louder but that are not that noisy at 5 volts.

Does the job
Good little fans, not the premium brand, but they work.

Very quiet with still a good airflow for cooling
I like how quiet these are. Very nice airflow. I have used these on a 3GHz small processor heatsink and various network switches. Effective and reliable. Happy to recommend, Andrew.

No sure about these
One fan didn't work from the start and seller never replied to a request for a replacement.

Cheap and Useful
These 40mm 5V fans come in a nice plastic case. The small 40mm 5V fans are very useful for smaller projects with MCUs, Raspberry Pis or MOSFETs involved so it's worth picking up a 5 pack. At about 2 bucks each, they're a pretty good value too. Running them at 60% PWM seems to be more than adequate cooling and also keeps them in a nice and quiet zone; when running them at full blast they do output quite a bit of air but also become high pitched and annoying.

Eine Empfehlung Wert
Super Lüfter für die Heizung, zur Zwangsbelüftung bei niedriger Vorlauftemperatur. Relativ leise und bis jetzt haltbar. Einfach Altes USB Ladegerät dran und parallel schalten.
