WINSINN 30mm 5V Fan - Hydraulic Bearing, 9000 RPM, 3010 Cooling Fan for Portable Devices, 30cm Cable with XH2.54-2PIN, Brushless 30x10mm (5Pcs)

I put these in a custom duct for cooling an 8 port SFP+ switch in my rack. They move a good amount of air and are quiet for a fan of this size that actually works.

Oddly enough, the PlayStation VR module given to me by my neighbor had no fan in it! The fan was missing entirely, and there was no indication that the module was pulled apart. The PS VR setup just failed due to heat after more than 10 minutes of playing. I looked into replacements (3-pin PWM fans), and nothing would be delivered short of three weeks from China. Just one fan would cost $18 USD. So I chose to go with this 2-pin fan. I soldered it up, and it works like a charm! It may be a bit louder when running, but there have been no issues with heat or the sound of the fan when the VR setup is used.

I bought the 10,0000 rpm hydraulic 24v version (5 pack) and they are dead silent. When i first installed it, i thought i had messed up a connection because i couldn't hear it running (i'm a young guy with good hearing). I had to shine a flashlight on the damn thing to see the fan was indeed going. I'm using it for my 3d printer and it seems to be doing the job quite satisfactorily. I had a 6 hour print the other day, and didn't notice any issues.

30mm fans are notoriously loud, especially on modern 3D printers. As such I wanted to replace the 30mm for the hot end on my 3D printer. Sadly these don't provide enough cooling for my purposes. That being said though, they are incredibly quiet and I will likely find some other application for them...

The brand that starts with g something time or whatever their name is from Amazon are leagues better. (I'd say the name of the brand but my review would be removed) But these things are not good! 100% failure rate, the first one was within days of installing it, after that the most i was able to get out now them was about 2 months. They're quite at first! Then they start to die and are obnoxiously loud! Like a 40mm fan shouldn't sound like a fighter jet. They're standard size, fit everything I used. But I won't suggest them because they die so quickly or theyre be a great value.

Tiny little fans come in handy when you are making odd things all the time. I use one on a V6 hot end clone, and the others have gone on various projects. These draw very little power, so a custom quick and dirty little boost regulator gets me up to 24V with no problem. They move enough air to be effective, but they can get a bit noisy depending on the environment and application. Smaller fans have to spin faster to produce airflow, so this was expected.

Ok these 5 fans were somewhere around $10. I got them for the hotend of my 3d printer. With that in mind I'm not going to complain that none lasted 60000 hours or whatever the laughable rating said. If you want that you probably need to get the tan with maroon blades fan, 1 for $20. If I don't have to make another order like this for 1.75+ years I'll have gotten my $ worth.

I see why they are so cheap. They hardly blow air. They are quite but quite doesn’t cool electrical components.

Sind bei etwa 4.6V erstaunlich leise, alle funktionieren. Einer surrte, etwas am Gehäuse herumdrücken hats behoben. Was mir auffiel, sie brauchen ein zwei Minuten bis sie ihre endgeschwindigkeit (und lautstärke) erreicht haben. Bin gespannt ob sie auch lange halten

Ventilateurs conforme à la description. La boîte en contient bien cinq. Il sont très silencieux, mais leur durée de vie est pas très bonne. Au bout d'un certain temps ils se mettent à vibrer et donc à faire du bruit, pas grave le stock est là pour ça. Après, tout dépend de la durée d'utilisation de la machine. Je recommande néanmoins ce produit, il fait ce pour quoi il est vendu à ce prix.

la ventola del v6 originale è molto più rumorosa di queste che si comportano bene, soddisfatto

Good value for the money spent.

Livrés dans une boite en plastique évitant tout dommage. Tous Ok, aucun ne présente de bruit suspect comme sur le premier achat d'un autre modèle vendu par paire. Je recommande
