Exact Replacement for Acer Aspire Z5771

This Delta BUB0812DD -CM75 fan is a direct 12 V replacement for the original CPU cooler in the Acer Aspire Z5771 all-in-one desktop. It matches the factory mounting pattern and power connector so the system recognises it immediately.

12 V DC Power Requirement

The unit runs on a 12 V DC supply; the motherboard header must provide this exact voltage or the fan will not spin. Builders using a different voltage rail or an adapter risk a non-booting system.

Straightforward Swap with Connector Care

Installation is a simple case-open, unplug, and refit procedure using the existing screws. The only common issue is forcing the delicate header pins, which can bend and leave the new fan undetected.

Questions about this item

What does the 12 V rating mean for the fan once it is installed in the Z5771?

The fan runs directly from the motherboard 12 V header, so it draws power without an adapter and its speed is controlled by the board PWM circuit.

Which connector standard does the BUB0812DD -CM75 use and what does it limit?

It uses a standard 4 pin PWM header, which caps the control signal to the motherboard fan curve and supplies the 12 V rail.

What mounting hole pattern does the cooler need to fit the Acer Aspire Z5771 chassis?

The unit is built to the original Z5771 bracket spacing, so the existing screw holes line up without modification.
