Targeted Cooling for Tight Spaces

The SXDOOL DB7530-12HBA is a 75mm blower fan built for targeted airflow in compact enclosures. Its centrifugal design pushes air through a 30 by 40mm outlet, making it suitable for small-form-factor cases, industrial chassis or component-specific cooling where standard axial fans cannot fit. The 12V DC motor draws a maximum of 0.45A for a nominal 5W power rating.

Voltage Range and Connector Constraints

The fan operates across a 4V to 15V range with a 12V nominal rating, but speed control is limited to voltage regulation via the three-wire interface. The 6cm lead ends in a standard three-pin plug carrying power, ground and tachometer signals only; pulse-width modulation is not supported. Builders must verify that their header or controller can supply the required current at the desired voltage.

Straightforward Mounting with Fixed Dimensions

Installation uses four screw holes on an 81mm square pattern that matches the 75 by 75mm frame. The short 6cm cable often requires an extension to reach motherboard headers in larger cases. The blower housing adds 30mm depth, so clearance behind the mounting surface must be confirmed. The ball-bearing motor weighs 85g and carries UL and CE safety marks.

Questions about this item

Is the DB7530-12HBA the only blower variant available in this 75 mm frame?

The DB7530-12HBA is the specific model listed; no alternative blower versions in the same 75 mm frame are shown.

What does the 0.45 A rating mean for actual cooling performance?

At 12 V the fan draws up to 0.45 A, delivering 5 W of power to move air through the 30 × 40 mm outlet.

How does the 3‑wire plug limit speed control options?

The 3‑wire connector provides power, ground and a tachometer signal; it supports RPM monitoring but not PWM speed control.
