Review: Mini power blower - These are small in size but moves lot of air. I am using it in one of my devices with Raspberry Pi to basically mover air from the case. It cools everything very effectively. Its loud at full speed, I drive these at lower voltage to reduce its speed slightly and the noise. I am not sure how long it will last but so far it seem fine in build quality.
Review: -(((Exactly what I needed)))- - Ordered these as I was needing some small and quiet fans for air circulation in a tree frog terrarium build. I had previously taken measurements of the clearance on the underside and top of terrarium top so I knew exactly what fans would fit perfectly into the position I had planned. Now, when these fans arrived in the mail, I did another careful measurement of the exact hole size needed to match up with the fan blade width. Along with pre-drilling the necessary screw mount holes. Everything was going as planned and was looking nice. On a side note, I had also ordered black metal mesh covers that would fit these small fans as I didn’t want any tree frog fingers going into those fan blades. :) after gathering up the screws I needed , I got to work getting everything mounted into place. Listen, I couldn’t be happier with how well this worked out. Not only does it work good, It looks like a professional factory installation. But I’ll let you be the judge by the photos I have added. The only thing left to do now is get the wiring to run down the underside bottom edge of inner lid. Since that will be a cakewalk, I will work on finishing that part first thing tomorrow. As for these fans I ordered here, these are perfect. They have speed control switch and I noticed that I could probably just run these on low for more than ample air circulation. You would be surprised by how quiet these are for how much air they push. That along with they aren’t creating any unnecessary vibrations or annoying sounds. I was worried I was gonna have to use a diy thin rubber gasket to mute that situation, but happily it wasn’t needed. These would definitely push more power than I would ever need for a terrarium, but like I said earlier, running these on low not only cuts that air flow down, but also keeps them at their quietest setting. I honestly can’t even hear these running while standing right in front of the tank. Now I can’t speak to how well these are at helping cool PC computer parts, And I can’t attest to how long the lifespan will be on these but I can tell you these were exactly what I needed for my project and worked perfectly for my personal needs. So maybe somebody reading this is looking for similar fans for a similar project. If so, these are the ones you should order. Just remember to buy those metal mesh fan covers that will fit this size of fan to keep your (inhabitants) safe. These do come with the fan grill covers, but those will not be good enough by themselves. So I used both. Hope you like the looks of how it turned out as much as I do, and I hope this review helps somebody out in some way. P.S. as another helpful tip if using these for the same purpose as me, think about pugging them into a auto timer. You can then just have them turning on and off by themselves when needed, like if you want to cool your terrarium during nighttime hours like a natural ecosystem. One simple way to accomplish this is to couple a/your lighting timer with these fans. For instance, fans power on at the same time the nighttime lighting clicks on, and daytime lighting powers off. If you plan on using a fogger for humidity control, it’s best to have them running on a separate auto timer. It’s best to only run them for about 20 minutes or so during the morning as the daylight lighting turns on. This creates that natural morning fog and dew on the morning grass scenario. Just keep in mind what will be living in your tank and what best suits their natural habitat, humidity, temperature, and weather situations. Have fun and create your own little world. :) if you like this review, give it a helpful vote. Thanks.

### ⭐⭐⭐⭐⭐ Powerful small fans for 3D printer
*by D***D on May 25, 2025*

Installed as part of a dual blower upgrade for my 3D printer, an ender 3 v2. The only complaint is they worked too well and I had to turn them down so the fans don’t go to 100% or else the hot end was cooled beyond the printer’s heating capability. They are mid tier on noise, not exactly quiet but definitely quieter than the stock fans they replaced. And since they aren’t running at 100% they stay lower in volume than basically any fan running full tilt. Would order again.
