I continue to prefer Noctua fans. This one replaces a minor chassis fan that became nois(-ier) (the cheap generic kind you get on a basic chassis) The Noctua is slightly thicker than the outgoing one but still fit in the space. So glad as the Noctua is quiet and moves "some" air - can't expect too much from such a small fan. This is a very crowded rack-mount chassis and this fan is helping the hard-drives get a little relief. My recommendation for Noctua is that I have several of their fans, starting with a CPU fan/cooler that fit and works well in a custom computer build. Now when a fan "situation" comes up, I just look up which unit fits (size and airflow) on the Noctua website and check eBay for the best price.

I recently bought my first server case, and had none of these tiny fans on hand. The server is not very high-performance, so the high-flow-but-super-noisy ones more typical in servers aren't really necessary. So, I decided to see whether there are any Noctua fans in this size, and behold--there are! These deliver everything I expect from Noctua, from the packaging to the performance. The temps in the case went down measurably, while the noise profile went up to "barely noticeable"--for this project, an acceptable tradeoff for me. I've been buying Noctua fans ever since I first tried them in a custom PC years ago, and while they're definitely toward the pricier side, the overall care given to the product and the noise/performance ratio is unbeatable.

Mounted fan on perforated metal like what you would see on pretty much any computer case fan mount. Here's why this fan is absolute garbage: If there is even the slightest obstruction to this fan's flow, ie grates or slots, THIS FAN WILL NOT FUNCTION. What happens is, due to the fact that the gap between the fan blade and interior of its frame is so huge, the fan blades push the air through the blades, and back out through the huge gap previously mentioned. I really have no idea how this fan ever made it past R&D, and I really don't understand how they ever came to the conclusion that they should charge $15 for it. AVOID THIS FAN. EXTREMELY flawed design/ non-functional.
I bought these for a slight case modification to try to get a bit more air flow. Works flawlessly. And are very quiet!
Would recommend for VRM cooling in cases that have the room, it is very quiet and now my VRMs dont overheat and throttle. I did not think to measure the distance from the fan header to where I was placing it, but the cable is kinda long for a small fan and worked out fine.
I would recommend this fan to anyone who is trying to focus on a quiet build. If you don't mind a little noise you can probably get away with a less expensive fan.
6 year warranty. I use these fans when replacing fans in Off Grid power inverters. They work out low cost. Because I only need to do the job one time. They last the life of the power inverters Great quiet fan
