    If you don't like little fans, you probably don't like little dogs. Both can sense that you are evil.

    Very powerful fan for its size! using it to keep my Samsung SM951 128GB cool.

    My mobo (Asus Tuf Mark 1 Z270) has a little slot in its "thermal armor" under a removable cover for installation of a 40mm fan... From my modest research it doesn't seem to make much of a difference (maybe 1-2 degrees Celsius under high load, and the evidence was mostly anecdotal), but I couldn't just leave that slot empty! Plus, I always wanted to tell at dinner parties about having a 40mm fan installed into my motherboard armor (just kidding, I don't do dinner parties).

    Sorry for the long story. This particular fan is of a high quality. I read about people running it for years non-stop doing minor cooling jobs. It's quiet and it's a very cute little guy! Just looking at the specs I couldn't find anything better for my needs but we all know that fans' specs have to be taken with a grain of salt. Noctua's reputation in that regard though hasn't been challenged yet, to the best of my knowledge. So I trust it moves few CFMs just fine and maybe even cools something while at it XD I named mine Quincy as I feel that this is a very special mighty little fan. A little fan that could.

    Have to mention that the packaging was impressive. Contrasts highly with a simple crappy box my Intel CPU came in.

    P.S. When installing the fan under the motherboard armor I had to use regular screws that came with the case, as the supplied fan screws seemed to be too large.

    What a tiny lovely little piece of a cooler!! <3 Looks like a small toy! No problems so far... Can't really hear it... but I hope its working over there... Very expensive in Brazil though... hahaha... But I simply HAD to get one since I found out my Z270 Mark 1 motherboard had a tiny spot for a small fan...

    besides the poo colour, this fan is the perfect replacement for the stock X570 chipset fan.
