Manufacturer description
The AC Infinity AXIAL 1225 is a 120mm AC muffin fan built for DIY cooling and ventilation projects where you need real airflow without a lot of noise. It moves 51 CFM at 1800 RPM while measuring 30 dBA, which keeps it quiet enough for a rack cabinet, AV closet, grow tent, 3D printer enclosure, or amplifier chassis that runs in a room you actually sit in. The aluminum frame houses dual-ball bearings rated for a 67,000-hour lifespan, and the fan is UL-certified, so it holds up to continuous duty rather than intermittent use. It runs directly on 100-120V AC through the included power plug cord…
SpecPicks Verdict
SpecPicks scored AC Infinity AXIAL 1225 using a rating × review-volume × price-fit model applied to published specs and reviews across the cooling & fans category. AC Infinity's cooling & fans lineup sits within the broader category mid-tier; price and specs are the deciding factors over brand loyalty here. Judge it on the specification table and the price rather than on sentiment: check the figures that decide your use case, then put it side-by-side with two or three close alternatives in the Compare tool before clicking through.

Frequently Asked Questions
How loud is the AC Infinity AXIAL 1225?
AC Infinity rates it at 30 dBA at its 1800 RPM speed. That is quiet for an AC muffin fan but still audible at close range in a silent room.
Will this fit a standard 120mm fan opening?
Yes. It measures 120 x 120 x 25 mm (4.7 x 4.7 x 1 in.), the standard 120mm form factor, so it drops into most existing 120mm cutouts and screw patterns.
Does it need a separate power supply?
No. It runs on 100-120V AC and includes a power plug cord, so it connects to a wall outlet without a DC adapter or fan controller.
Can I mount it sideways or upside down?
Yes. AC Infinity states the fan can be mounted in any direction, which is what the dual-ball bearing design allows.
How long will this fan last running continuously?
The dual-ball bearings are rated for a 67,000-hour lifespan, and the fan is UL-certified. Check the product listing for current warranty terms.
