Compact blower for CPU coolers

The Zyvpee AB07612UB300BM2 is a 77 by 75 by 30 millimetre DC blower designed to mount on CPU coolers. Its four-pin PWM connector allows the motherboard to regulate speed automatically, while the ball bearing supports continuous operation in tight chassis layouts.

PWM control and noise envelope

The fan spins between 3500 and 3999 RPM under PWM control, drawing 0.63 amperes at 12 volts. Acoustic output stays in the 30 to 35 dBA range, so the blower remains audible but not intrusive when the cooler demands maximum airflow through a restricted heatsink.

Airflow focus and limits

The blower format concentrates pressure rather than volume, making it suited to dense fin stacks where axial fans stall. It cannot move the same free-air volume as larger case fans, and the 30 millimetre thickness restricts use to coolers and brackets built for this exact footprint.

Questions about this item

How do I know if the 77x75x30mm blower fits my CPU cooler?

Measure the mounting holes and shroud clearance on your cooler; this unit is 77 mm wide, 75 mm deep and 30 mm thick with a four-pin PWM connector.

What does the 3500-3999 RPM range mean for actual cooling?

At full speed the blower moves more air through a tight heatsink, while PWM lets the motherboard drop speed for quieter operation at lower loads.

What does the four-pin PWM connector control?

It carries 12 V power, ground, a tach signal and the PWM duty cycle so the board can vary speed between 3500 and 3999 RPM.
