Frequently asked questions
What voltage does this fan need?
It is rated for 12 V DC. Do not power it from a 5 V supply, since it is designed for 12 V operation.
How do I wire the fan?
Connect the fan's positive and negative leads to a 12 V DC supply with correct polarity. Confirm the wire colors on your fan, since some 40 mm fans have an extra third wire.
