Manufacturer	Spire
Model	Starflow SP519S7
Price	$15
Category	Entry Level

The StarFlow is the next extremely silent retail cooler from Spire.

The new fan is an evolved version of the "CoolBlue" DC fans.

Spire engineers have reduced the spokes that hold the fan motor and elevated these to create a greater air intake area and to reduce the resistance of spokes which sometimes can cause a high-pitched sound.

It reaches a maximum noise level of only 19dBA and still manages to push a whopping 42.28 CFM at a 2.000RPM.

- Features

* Extremely silent BlueStar DC Fan
* Aluminum based Star-Heatsink design
* Secure and solid installation
* Silent at only 19.0dBA!
* Retail packed in full color packaging

- Retail package

The retail package of Spire Starflow is very small, this cpu cooler aims for entry level users.
