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.

Good Quality, Good Price
Bought the box of 5 and used 2 as replacement cooling fans for my LOREX CCTV DVR (plugged right in). It's been months and they work fine 24/7. For the price it's worth it and I have 3 more as spares. They push decent air and are not noisy.

Very Quiet
This small fan is truly quiet, just like they claim. I bought the 5,000 rpm model. you may have to cut and splice the wires if the connector supplied does not fit your application.

Reversed polarity
Worked well with Geekworm X1200 5V UPS HAT Expansion Board for Raspberry Pi 5 but know you'll have to cut thr wires and reverse the polarity for it to work
User
Excellent quality
Strong little fans wired a couple together for more flow, cranking up the voltage doesn’t seem to phase these little guys. Excellent quality

For my arrma fury Rc car
Got these for my Arrma fury. They are the correct voltage for the esc output and they are a lot quieter than the original fan. They still move enough air for cooling the motor. I peeled back the sticker on the back and hardwired a futaba j plug directly on the motor. I don’t know how long this will last in the dirt but they’re only $.50 apiece.

Good fans.
Needed one to replace a noisy one on a LI-ION battery tester/charger. Quantity and price was good and now I have spares and for other uses.

Bearings fail within a year
These do not last long. In all of the fans the bearings fail and the fan freezes within a year. This causes an overheat condition in my POE switch. Do not buy.
User
No sure about these
One fan didn't work from the start and seller never replied to a request for a replacement.

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.
