SKU CH-HZS4-CQ0QF

Pack of twenty 40 mm DC 12 V 3-pin case fans with blue LEDs

  • 20 fans included for multi-point chassis cooling
  • 40 mm square frame fits tight mounting spaces
  • 12 V DC 3-pin power for standard motherboard headers
  • Blue LED lighting adds visible airflow indication

20-piece 40 mm fan kit

This pack contains twenty 40 mm square fans with a 10 mm thickness, each running on 12 V DC power through a three-pin connector. Blue LEDs are integrated into every unit for visible lighting inside the chassis. The 4010S model is intended for compact case ventilation or targeted component cooling. Buyers needing larger airflow volumes or quieter operation at lower RPM should consider different form factors.

Standard three-pin mounting

The three-pin headers plug directly into matching motherboard or controller sockets, allowing voltage-based speed regulation where supported. Uniform 40 mm dimensions mean the fans fit tight grids in small-form-factor builds, rack enclosures or custom cooling brackets. Blue illumination remains constant while the fan spins, providing a consistent visual indicator of operation. Installers without enough three-pin headers will need a splitter or hub to connect the full set.

Questions about this item

What does the 3-pin connector limit for speed control?

The 3-pin connector allows voltage-based speed adjustment but does not support PWM signalling for precise duty-cycle control.

What clearance is needed to mount these 40 mm fans?

Each fan measures 40 x 40 x 10 mm, so a 40 mm square cut-out with at least 10 mm depth behind the panel is required.
