  • Direct 12 V power for stable operation
  • Low 0.14 A draw keeps system load light
  • 40 mm square frame fits tight GPU spaces
  • Dual 9 mm or 10 mm thickness options
  • Three-pin connector enables speed monitoring

Replacement VGA fan for T&T 4008M12B NF1

This 40 mm 3-pin fan is built as a direct replacement for the T&T 4008M12B NF1 cooler used on graphics cards. It runs on 12 V at .14 A and fits the standard 40 mm square footprint. The unit is supplied new and ready to install.

3-pin connector and dual height profile

The 3-wire 3-pin connector provides power and tachometer feedback to the graphics card header. Two frame thicknesses are offered, 10 mm and 9 mm, so the same model covers both common mounting depths. No extra cables or adapters are included in the package.

40 mm square frame with 3-pin header

The critical fitment detail is the 40 mm by 40 mm frame combined with a 3-pin header; if your card uses a different screw pattern, connector pin-out or voltage, this fan will not mount or report speed correctly. Builders needing a 2-pin or 4-pin PWM connector, or a larger frame size, should look elsewhere.

Highlights

  • Low 0.14 A draw keeps system load light
  • 40 mm square frame fits tight GPU spaces

Questions about this item

Does the 3-pin connector on this 40 mm fan support speed reporting so I know when to replace it?

The 3-wire 3-pin interface provides a tachometer signal, letting monitoring software track RPM and warn you when the bearing wears out.

What thermal limit stops this 12 V .14 A cooler from running indefinitely at full load?

The motor is rated for 12 V and 0.14 A; sustained operation at that draw will hit the bearing’s temperature ceiling before any electrical limit.

How loud and hot does the T&T 4008M12B NF1 get when it spins all day in a graphics card?

At 12 V and 0.14 A the fan produces a low whisper-level noise and only slight warmth, typical for a 40 mm frame in constant use.
