SXDOOL

SXDOOL AVC BASA0615R2M 12V .3A 4-pin 60x63x14mm case fan

SKU CH-2V2T-MBG0S

A 12V 4-pin case fan measuring 60x63x14mm for Haier Q31 Q33 Q35 Q36 and Lenovo B305 systems

  • 4-pin PWM control enables precise speed adjustment
  • 12 V .3 A rating keeps power draw low
  • 60 x 63 x 14 mm frame fits tight chassis spaces
  • Direct replacement for Haier Q31 Q33 Q35 Q36 and Lenovo B305
  • 4-wire design supports RPM monitoring and automatic fan curves

Direct replacement for Haier and Lenovo systems

The SXDOOL AVC BASA0615R2M is a new 12V .3A 4-pin case fan built to match the original cooling unit in Haier Q31 Q33 Q35 Q36 and Lenovo B305 desktops. It fits the existing mounting points and connector without modification.

Four-wire PWM control within a 60x63x14mm frame

The 4-pin interface allows the motherboard to regulate speed precisely, but the physical envelope is fixed at 60 by 63 by 14 millimetres. Builders must verify that their chassis and motherboard header accommodate this exact footprint and pin layout before ordering.

Swaps the OEM fan when noise or failure occurs

This unit replaces the factory AVC BASA0615R2M when the original becomes loud, stops spinning or shows bearing wear. The upgrade is worthwhile only if the system still uses the same 12V 4-pin header and the 60x63x14mm clearance remains unchanged.

Questions about this item

Which model numbers does this AVC BASA0615R2M fan replace?

It is listed as a direct replacement for Haier Q31, Q33, Q35, Q36 and Lenovo B305 systems, matching the original 12V 0.3A 4-pin specification and 60x63x14mm dimensions.

What does the 0.3A current draw mean for my motherboard fan header?

At 12V the fan draws 0.3A, which is well within the typical 1A limit of standard 4-pin headers, so it will run safely without overloading the circuit.

How does the 4-pin connector control speed compared to a 3-pin fan?

The fourth wire carries a PWM signal from the motherboard, allowing precise electronic speed control instead of voltage reduction, so the fan can run quieter at low loads.
