Fixed my broken one
Found these to replace the broken fan inside my daughters humidifier. Works perfect again. I really didnt want to buy a pack of these but for the cost, its worth having them if i ever need one again. Just wish they sold them single for cheap. It was as described and satisfied with my purchase.

Great little blower fans
It was nice to have 4 to pick from. One of the ones that was shipped makes lots of noise on startup, taking about 5 minutes for the bearings to warm up. Once it's warmed up, it's nice and quiet. These are good, cheap fans. The power cable connectors were reversed for the MKS Gen L board I hooked them to.

Quiet Fans, although Not Ideal for 3D Printing
I bought these fans as a replacement for my Prusa i3 MK2.5 part cooling fan. This fan is really quiet and doesn't have a lot of vibration, so I have to say they're built pretty well. Even turned all the way up, they're barely audible. They also don't consume very much power--I measured around 90 mA at full speed. Unfortunately, these fans don't quite move enough air for part cooling in a 3D printer. There's a marked reduction in airflow compared to my original fan; I estimate at least a 2x difference. To be fair, these fans are useful for many other things besides 3D printing, and they seem to be quality fans, so I'll give credit for that. My only real complaint is the lack of documentation--specifically it would have been nice to see some figures for airflow (CFM) and rotational speed (RPM), so customers could better decide if this fan meets their requirements. For that, I'll have to take off one star from an otherwise great fan.

Small but mighty
Mighty worth all 4. Cooling all my equipment.

Work fine, came as described
All four fans worked well, contrary to some negative reviews on this product. If you are working in CAd, it can be a little difficult to get the dimensions correct, and it took me six or seven iterations to make a mounting plate with a geometry for these, though that may be more of a problem of me just being terrible at measuring the correct dimensions.

My previous disinfection cabinet was broken. I bought this one and found it can't be used. I don't know if it's because I don't know how to install it.

Works great
I tested only one so far, others are spare. Works great. Edit after futher testing : I have compared it to others fan of same size with respect to flow and static pressure. This blower is indeed the quietest but provides the lesser flow and pressure. I recommend it only if you need low noise and that you dont need big airflow performance. For 3D printer, if the airflow is not too much restricted and the fan not too far from the object to cool, it is totally fine. Direct blow without fancy air duct is best. In my application where i need the airflow pushed though a filter, this blower is too weak so i will use others.

Effiziente Kühlung für 3D-Drucker mit den WINSINN 5015 Lüftern
Die WINSINN 5015 Lüfter sind eine ausgezeichnete Wahl für alle, die ihre 3D-Drucker optimal kühlen möchten. Mit einer Größe von 50 mm x 15 mm und einer Spannung von 12 V bieten diese bürstenlosen Lüfter eine zuverlässige Kühlung, die besonders für die Nutzung in 3D-Druckern konzipiert ist. Einer der Hauptvorteile dieser Lüfter ist ihre hohe Effizienz. Sie bieten eine beeindruckende Luftzirkulation, die entscheidend ist, um Überhitzung während des Druckprozesses zu vermeiden. Die Installation ist unkompliziert; die Lüfter sind mit einem 2-Pin-Anschluss ausgestattet, was die Integration in die meisten 3D-Drucker erleichtert. In nur wenigen Minuten können sie montiert werden, was für Einsteiger und erfahrene Anwender gleichermaßen von Vorteil ist. Die Qualität der Lüfter ist bemerkenswert. Das Hydrauliklager sorgt für einen leisen Betrieb, was besonders in Umgebungen von Vorteil ist, in denen Lärm minimiert werden soll. Im Vergleich zu anderen Lüftern, die laute Geräusche erzeugen können, überzeugen die WINSINN Lüfter durch ihre angenehme Betriebslautstärke. Dies ist ein erheblicher Pluspunkt, besonders wenn man oft über längere Zeiträume druckt. Jedoch gibt es auch einige Aspekte, die beachtet werden sollten. Einige Nutzer haben berichtet, dass die Lüfter gelegentlich etwas schwächer in der Luftzirkulation sind, insbesondere bei höheren Druckgeschwindigkeiten. Dies könnte bedeuten, dass man je nach Anwendung möglicherweise mehrere Lüfter installieren muss, um die gewünschten Ergebnisse zu erzielen. Zudem könnte die Lebensdauer der Lüfter bei intensiver Nutzung etwas begrenzt sein, was man im Hinterkopf behalten sollte. Insgesamt bieten die WINSINN 5015 Lüfter ein gutes Preis-Leistungs-Verhältnis und sind eine sinnvolle Investition für alle, die ihre 3D-Drucker kühl und funktionsfähig halten möchten. Ihre einfache Installation, die geringe Geräuschentwicklung und die effektive Kühlung machen sie zu einer empfehlenswerten Wahl für Hobbyisten und Profis gleichermaßen.
