SKU CH-16JZ-1AH5Y

A 45 mm maglev case fan running on 12 V with a three-pin connector

  • Maglev bearing reduces friction and noise
  • Compact 45 mm square frame fits tight spaces
  • 12 V three-pin power for standard motherboard headers
  • 10 mm slim profile suits low-clearance builds

Maglev Fan B1245PFV1 45mm

This Maglev fan measures 45 by 45 by 10 millimetres and runs on a 12 volt three pin connection. Magnetic levitation reduces mechanical friction for quieter operation. The compact frame fits tight spaces in small form factor chassis. It is built for targeted component cooling.

Suits builds needing a 45mm replacement

This fan suits builders who need a 45mm maglev cooler for confined layouts. Buyers who want larger airflow volumes should look at something else. Systems requiring PWM speed control cannot use the three pin header. Cases without 45mm mounting points will need a different size.

Questions about this item

What clearance does the 45 mm square frame need inside the case?

The fan is 45 mm wide, 45 mm deep and 10 mm thick, so allow at least that much space plus room for the three-pin connector.

How do I connect the 3-pin plug to a 12 V header without reversing it?

Align the keyed tab on the connector with the missing pin on the motherboard header; the fan will only seat one way, preventing reverse polarity.
