Unique-Bargains 2-Pack 24V 40x40x10mm Case Fan

SKU CH-JCDN-N5S1G

Two 40 mm brushless fans move air at 24 V and 0.06 A with 18 cm cables and three-pin connectors

  • Pushes hot air out of the case
  • Draws fresh air in when front-mounted
  • 24 V DC brushless motor runs at 0.06 A
  • Compact 40 mm square frame fits tight spaces
  • 18 cm cable with 3-pin connector reaches motherboard headers

Two-pack 24 V case fans

This pack contains two 40 x 40 x 10 mm brushless fans rated for 24 V DC at 0.06 A. Each unit uses a 1.3 pin connector and ships with an 18 cm cable. The plastic frame measures 1.6 x 1.6 x 0.39 inches and is finished in black. They are designed to exhaust hot air from the rear or draw cool air in through the front of a chassis.

Suited for 24 V cooling slots

Builders with a 24 V fan header or external 24 V supply can use these fans directly. Systems that only provide 5 V or lower-voltage headers cannot drive these units. The twin-pack format also limits usefulness for single-fan replacements or arrays needing three or more matching fans.

24 V DC operating voltage

The fans require a 24 V DC source rated for at least 0.06 A per fan. Connecting them to a different voltage will prevent operation or cause damage. Verify that your motherboard, controller or power supply delivers exactly 24 V before installation.

Questions about this item

Does the 1.3 pin connector deliver a standard PWM signal or only voltage control?

The 1.3 pin connector supplies power and a tachometer signal; it does not carry a PWM line, so speed is managed by varying the 24 V supply voltage.

Will the 40 x 40 x 10 mm frame fit a standard 40 mm mounting grid?

Yes, the 40 mm square frame matches the common 40 mm hole pattern; the 10 mm thickness clears most chassis walls and drive cages.

How do I connect the 18 cm leads to a motherboard header that expects a 4-pin plug?

Use a 3-pin to 4-pin adapter or plug the 3-pin connector directly onto the 4-pin header, aligning the key; the missing PWM pin will be ignored by the board.
