80mm 12V server-grade case fan
The SXDOOL ADDA AD0812UX-C73 is an 80mm square frame fan built for continuous server and inverter cooling. It runs on 12V DC at .40A and connects through a standard 3-pin power header. The hydro bearing is rated for 180000 hours of optimal continuous operation.
Replaces worn 8020 fans in tight enclosures
This unit fits the 80x80x20mm footprint used by many legacy servers and industrial chassis. The jump is worthwhile when the original fan has seized or slowed below 4000 RPM, restoring rated airflow without modifying mounting holes or wiring.
3-pin voltage control limits speed precision
The 3-wire interface adjusts speed by varying voltage rather than PWM duty cycle. This means the motherboard or controller cannot command exact RPM targets between 4000 and 4499 RPM, and the fan will always spin whenever power is present.

שאלות על הפריט הזה
What size mounting holes does the 80mm ADDA AD0812UX-C73 need?
The fan measures 80mm x 80mm x 20mm, matching standard 80mm case mounts with four corner screw holes.
How do I connect the 3-pin connector on the AD0812UX-C73, and what mistake should I avoid?
Plug the 3-wire 3-pin interface into a motherboard 3-pin or 4-pin fan header; do not force it onto a 2-pin header or the tachometer wire will be left unconnected.
When will the double ball bearing in this fan need replacement?
The high-precision double ball bearing is rated for 180,000 hours of optimal continuous operation before wear requires a swap.
