  • Fan size30 mm
  • Ultra-compact 30 mm frame fits tight spaces

  • Short 5.5 cm lead with 3-pin plug simplifies installation

Compact 30 mm 5 V ball-bearing fan

This 30 mm case fan fits tight spaces in routers, switches or small-form-factor PCs. It runs on 5 V with a working range of 3 V to 6 V and draws 0.9 W. The ball bearing is rated for 100,000 hours of continuous operation.

Limited airflow for low-heat enclosures

The small frame and low power suit chipset coolers or single-board computers but cannot move enough air for modern CPU or GPU heat loads. The 5.5 cm lead uses a miniature three-pin plug that may need an adapter for standard motherboard headers.

Questions about this item

Will the 5 V ball-bearing fan spin reliably on a legacy 3-pin header that only supplies 5 V?

Yes, the fan is rated for 5 V and its working range is 3 V to 6 V, so a 5 V header will keep it running within specification.

How can I confirm the 0.9 W fan is operating correctly once installed?

Listen for smooth, quiet rotation and verify the motherboard or controller reports a steady RPM signal through the 3-pin connector.
