Compact 80 mm CPU fan

The OEM Industries AD0812MB-D91GP is an 80 mm ball-bearing cooler designed for 12 V systems drawing 0.15 A. It suits builders replacing a noisy stock fan in tight chassis or upgrading legacy sockets where larger towers cannot fit. Buyers who need higher static pressure for dense heatsinks or liquid radiators should look elsewhere.

Two-wire power connector

The bundled 2-pin lead delivers fixed 12 V power without PWM control, so the fan runs at a constant 2500 RPM ±10 %. No RGB lighting, adapters or mounting hardware are included, keeping the package minimal for system integrators who supply their own brackets.

Straightforward drop-in install

Four standard mounting holes align with common 80 mm patterns, and the 15 mm thickness clears most low-profile heatsinks. The only frequent issue is cable reach in full-tower cases, where the short two-wire lead may require an extension.

Questions about this item

Will the double ball bearing in the AD0812MB-D91GP need lubrication or replacement over time?

Double ball bearings are sealed and do not require lubrication; they typically last for tens of thousands of hours before any replacement is considered.

At 2500 RPM and 24.95 CFM, what limit appears first during continuous operation?

The airflow of 24.95 CFM sets the cooling ceiling; sustained loads that exceed this dissipation will cause temperatures to rise first.

How much noise and heat does the 12 V 0.15 A fan produce when running all day?

At 2500 RPM the fan generates audible but moderate noise, and its 0.15 A draw at 12 V adds minimal heat to the case environment.
