120 mm blower fan for compact CPU coolers

This 120 mm blower-style fan is built for CPU air coolers that need directed airflow through a heatsink. It runs on 12 V and draws 1.1 A, making it suitable for systems that require focused cooling in tight spaces. The 4-wire connection enables PWM speed control for quieter operation at lower loads. It contains no LED lighting.

Check 4-pin PWM header and 12 V supply

Verify that your motherboard or fan controller provides a standard 4-pin PWM header and can deliver 12 V at 1.1 A. Confirm the physical clearance around the CPU socket matches a 120 mm blower frame, as the housing extends beyond the fan blades. Ensure the mounting holes align with your cooler’s retention mechanism before ordering. Buyers who need a slim axial fan or a 3-pin voltage-controlled model should look elsewhere.

Black blower housing with 4-wire PWM lead

The black plastic frame houses a Nidec 12032 motor rated for continuous 12 V operation. A 4-wire lead terminates in a standard PWM connector for direct motherboard control. The blower design exhausts air perpendicular to the intake, which helps push heat through dense fin stacks in low-profile coolers. No additional mounting hardware or adapters are included.

Questions about this item

Does the NIDEC 12032 A35451-34 blower fan ship with mounting screws or a power adapter?

The unit is supplied as the fan only. Mounting hardware and any required cable adapters are not included and must be sourced separately.

How do I confirm that the A35451-34 is the correct replacement for my existing blower?

Match the model number A35451-34, the 120 mm frame, 12 V 1.1 A rating and the four-wire PWM connector against the label on your current fan.

What does the 1.1 A current draw mean for everyday cooling performance?

At 12 V the fan can draw up to 1.1 A, giving the motor enough power for high static pressure in tight chassis or heatsink fins.
