NF-A4x10 5V,NF-A8 FLX,NF-A8 PWM,NF-A8 ULN

Starting with the NF-A4x10, this 40x10mm sized fan is one of the smallest I’ve ever encountered. Powered by a minimum of 5 volts, the tiny case fan operates effectively even at high RPMs, but has the slight drawback of a slightly high pitched noise at full power; the sound can reach to around 20db, although where this fan would be used, noise would clearly not be an issue. I found the NF-A4x10 to be perfect for users who use the popular Asus Sabertooth Mark 1 with TUF armor as the fan is small enough to be placed next to the rear I/O or underneath the TUF armor. Moving on to the next model in the lineup, the NF-A8. With its 80mm specification, the NF-A8 is suitable for hard drive bay cooling or micro-ATX cases where space saving is crucial. Although the NF-A8 supports a larger form factor, the noise is significantly quieter at 16db. Last in the arsenal is the NF-A9. Designed to operate as a rear case fan, CPU cooling fan, or inside a micro-ATX case, its 92mm size makes it the most desired out of the three models. At maximum performance, the NF-A9 is the loudest of the bunch reaching sound levels between 20db and 22db. However, compared to the NF-A4x10 the 92mm size allows it to be quieter without any pitched noise.

"In the end, the NF-A4x10, NF-A8 and NF-A9 fans comply with Noctua’s Premium Fan statement. Backed by an outstanding six year warranty, these fans should last a computer’s life time without you needing to replace them. With pricing starting at $18.95 for the NF-A8, $19.99 for the NF-A9, and $23.99 for the NF-A4x10, you can’t go wrong buying these fans." (Justin Vendette, TechSupportForum.com)
