Fans 50pcs 4028 12V .66A 40x40x28mm case fan

50-piece 40 mm server fan pack

This pack contains fifty 40 mm square fans built to the 4028 form factor. Each unit runs on 12 V and draws .66 A. The 28 mm thickness matches the standard 1U server profile. The quantity suits batch maintenance or spares stocking for dense rack installations.

Verify 12 V header and 40 mm mounting

Confirm that your chassis or backplane provides a 12 V fan header for each position. Check that the mounting holes accept a 40 mm square frame and that the 28 mm depth clears adjacent components. Ensure the combined current draw of all connected fans stays within the header or controller rating.
