I just unboxed this fan and installed it on my 12U mini server rack that I'll be using to mine bitcoin. This fan will do the trick for sure to keep temps under control. On high this Fan is super loud, on low its whisper quiet. I can turn it down to just under half speed and the noise isn't bad for a mining rig. The speed control is infinite, meaning it doesn't click from speed to speed, you can dial it in exactly where you want it. There is zero rattle or other noise, only just the fan noise, which is nice. It comes with two grills and four screws and nuts for a quick and easy install. I really like this fan and consider it to be an excellent value. I installed it on my mini server rack, first I mounted it on top, but it was a bit too loud. Then I tried to mount it on the bottom of the top panel and I was getting a weird reverberation that wasn't consistent. I realized that the metal grill on the top panel was blocking about 50% of the air flow, so I used a dremmel and cut out the top grill and then polished the edges. Now I'm getting incredible air flow with no weird sounds! And the noise is really reduced being inside of the cabinet. I tried to measure the watts but my bluetti doesn't go that low so I plugged in a small heater and then turned the fan on high to see the difference, it was about 13 watts.

Works great! I use it for a 3d printing enclosure. I like to be able to adjust the air flow with ease.

This fan is top notch! It moves a lot of air to keep mining rigs cool.

I purchased this fan to cool my apartment’s circuit breaker box for when I run my floor-standing AC unit. In extreme heat my apartment gets up to 96F upstairs and when I run my AC unit, the breaker trips after 30-40 minutes of running the AC. This morning I mounted the fan in front of the breakers in the hope that it will cool the breakers enough to keep the AC going. It’s currently 100F outside and I’ve been running my AC for nearly 2 hours straight without the breaker tripping. So far, so good 😁.

Works as designed. A little noisy if turned up but it moves air for sure..
