SKU CH-00D1-Z8SQP

A 12 V, 0.22 A DC case fan with three wires and 2.7 mm by 3.5 mm mounting holes

  • 12 V 0.22 A power draw keeps energy use low
  • Three-wire connection supports speed monitoring
  • Mounting holes spaced 2.7 mm by 3.5 mm fit tight layouts
  • Designed as direct replacement for ADDA AD0512UB-TB3

Replacement fan for ADDA graphics cards

This 12 V, 0.22 A case fan matches the AD0512UB-TB3 specification used on select ADDA graphics card coolers. It arrives new and ready to install as a direct replacement for a worn or noisy original unit. The three-wire connector provides speed reporting to the board.

Mounting holes spaced 2.7 mm by 3.5 mm

The screw-hole pitch of 2.7 mm by 3.5 mm is the critical dimension that decides fitment on the target heatsink. Verify this exact spacing against the original fan before ordering, as other pitches will not align. Buyers needing a different hole pattern or a larger frame will need another model.

Questions about this item

What does the 12 V .22 A rating mean once the fan is installed on a graphics card?

The fan draws 0.22 A from the 12 V rail, so the card's fan header must supply at least that much current for reliable start-up and speed control.

How does the 3-wire interface affect speed control on a GPU?

The third wire reports RPM to the graphics card, allowing the firmware to monitor speed, but voltage regulation on the header still determines the actual fan speed.
