Cleaned everything the best I could before storing (approximately 1y). Thought I'd use them in another build for family/friends but that didn't happen.

All extra pieces are included along with original packaging except for some of the anti-vibration screws which tore upon removal.

Units can be sold separately but are best sold as the entire lot of 5 to complete most E/ATX builds.

Here's a few other details from what I could gather...

One of the world's quietest fans with breakthrough technology and innovation.

Beautifully finished dual color and material fan

The world's first dual-layered fan blades - a combination of plastic and rubber fan blades to decrease wind noise.

Dimpled golf ball like surface on the back rubber side of the fan blades minimizes turbulence.

Optimized fan blade angle design for a perfect balance of airflow and noise.

Noise and shock reduction frame incorporating four rubber silencer blocks and anti-vibration rubber pads on each of the mounting holes.

Fluid dynamic bearing delivers longer life span, higher precision rotation and anti-shock function.

Low 3-volt starting voltage.

Four anti-vibration screws (again, some had torn during removal) are included for easier installation.

Power cables are black sleeved with both 3-pin and 4-pin molex connectors.

Low speed 7V volt reduction cable included for ultra-low speed with minimal noise.
