SXDOOL 80mm 12V 8025 Dual Ball Bearing 4000RPM 3-Pin Case Fan

SKU CH-3WZZ-4KGNJ

An 80 mm case fan with dual ball bearings, 12 V power, 4000 RPM speed and 50 CFM airflow, rated for 50000 hours

  • TypeCase Fan
  • Fan Size80mm
  • Bearing TypeBall
  • Power Connector3 Pin
  • High airflow of 50 CFM moves heat quickly from tight cases
  • Dual ball bearing rated for 50000 hours extends service life
  • 4000 RPM at 12 V delivers strong static pressure for dense heatsinks
  • Compact 80 × 80 × 25 mm frame fits small-form-factor builds
  • Standard 3-pin KF2510 connector plugs straight into motherboard headers

80mm 12V Case Fan for Compact Builds

This 80mm case fan fits standard 80x80x25mm mounting points in small-form-factor chassis or legacy systems. It runs on a 12V DC supply drawing 0.27A and spins at 4000 RPM to move 50 CFM of air. The three-pin connector plugs directly into motherboard headers for basic speed reporting.

Dual Ball Bearing Extends Service Life

Two ball bearings replace the more common sleeve design, reducing friction and wear over time. The manufacturer rates the assembly for 50000 operating hours while maintaining high rotation precision. CE and RoHS markings confirm compliance with European safety and substance restrictions.

3-Pin Connector Limits Speed Control

The 3-pin KF2510 connector provides power, ground and a tachometer signal but lacks the fourth PWM wire required for automatic duty-cycle control. Builders who need motherboard-managed fan curves should verify header compatibility before purchase.

Questions about this item

How long before the dual ball bearing on the 8025 fan needs replacement?

The dual ball bearing is rated for 50000 hours of operation, so replacement timing depends on daily run hours.

What limits continuous running at 4000 RPM?

The 0.27 A current draw at 12 V sets the electrical limit, while the 50 CFM airflow rating reflects the thermal limit under sustained load.

How loud and hot does the 80 mm fan get when it runs all day?

At 4000 RPM the fan moves 50 CFM; noise and heat rise with speed, but no specific dBA or temperature figures are published.
