Blower fan using a Seagate HDD

This is an impeller blade type of blower fan to be used on a donor Seagate 2TB HDD (specific model number used here is ST2000DM001)... not sure if it'll fit other HDDs but should be relatively standard size.

The HDD came free with a NAS I bought and was beyond repair. So I decided to have a little fun.. the HDD circuit board was nice enough to spin up to full 7200rpm as soon as it's powered so it can be used as a cooling fan inside the computer case. have fun..
