Noctua NF-A4x10 FLX 40mm Fan Review

Noctua is well known for their cooling products, especially their fans. I for one love them, they’re quiet and they work great. I always swap out the fans in a case for Noctua ones and I use a Noctua CPU cooler as well of course. Noctua has recently released a few specialized fans for uses other than inside of your PC case. The news fans vary in size and today I have the 40mm version for review, specifically it’s the NF-A4x10 FLX fans which is 40mm by a mere 10mm thick, which means it will fit in tight places easily. I wasn’t sure how exactly to review a fan like this, but then I started thinking harder about what I use in my computer and found something that I use all the time that happens to use a 40mm fan. I went about swapping the fan out and overall I’m happy with the results. Read on to learn more about the fan, and see just what I did with it…
