Orion OA825AP-11-1TB 80x25mm 115 VAC Fan - Quiet 3000 RPM

In this review the Orion OA825AP-11-1TB is presented for builders who need a compact, mains-powered cooling fan with consistent airflow. The bottom line: this 80x25mm fan is best for small enclosures and targeted component cooling because it delivers a steady 25 CFM while running from 115 VAC, making it easy to install where a dedicated DC supply is not available. Noise is modest at 28 dBA, and the 3000 RPM speed gives predictable performance without extreme power draw.

Key Features

• 115 VAC rating: Allows direct connection to standard AC mains for installations without a DC supply, simplifying wiring in many enclosures.
• 80x25mm size: Small footprint fits tight spaces and can be used to supplement larger system cooling in constrained areas.
• 25 CFM airflow: Provides focused air movement useful for spot-cooling drives, VRMs or compact power supplies.
• 3000 RPM speed: Higher rotational speed offers steady airflow and predictable thermal behavior under load.
• 28 dBA noise level: Relatively low audible output for a fan at this speed, suitable where moderate silence matters.
• 9 W power draw: Moderate consumption given the 115 VAC operation, balancing performance and energy use.

Who It's For

The Orion OA825AP-11-1TB is aimed at technicians, hobbyists, and system builders who need a small AC-powered fan for auxiliary cooling in electronics enclosures, network cabinets, small chassis, or legacy systems where AC is the available source. Its compact dimensions and 115 VAC rating make it a practical choice for retrofit projects and equipment racks.

It is less suitable for those who need ultra-low noise or the highest possible airflow for large cases; users seeking variable-speed control or PWM integration should look for DC fans with dedicated control features instead of this fixed-speed AC model.

Pros & Cons

Pros

• Direct AC operation removes the need for a DC supply or extra wiring when mains power is available.
• Compact 80x25mm form factor fits into tight spaces that larger fans cannot reach.
• Balanced performance with 25 CFM at a reasonable noise of 28 dBA for many small-enclosure uses.
• Moderate 9 W power draw is acceptable for continuous operation without excessive heat from the motor.

Cons

• Fixed speed and AC operation limit controllability compared with DC or PWM fans for advanced thermal management.
• Not ideal as the sole cooling source for large cases that require higher total airflow.

Frequently Asked Questions

Can this fan be connected directly to wall power?
Yes, the OA825AP-11-1TB is rated for 115 VAC and is intended for direct connection to standard AC mains in appropriate installations.

Is the noise level suitable for quiet rooms?
At 28 dBA it is relatively quiet for an 80mm fan, but it may still be audible in very quiet rooms; consider larger low-RPM DC fans if near-silence is required.

Can the speed be controlled with a fan controller?
This model is an AC fixed-speed fan, so usual DC PWM controllers will not work; AC speed control requires compatible AC regulators and is generally less common.
