The GAMEMAX FN12A-S8I-RW is a 120 x 120 x 25mm case fan with a white frame and nine semi-transparent white reverse blades. It is the reverse-blade version of a standard 120mm ARGB fan, built for the mounting positions where a normal fan ends up showing its rear side to the window instead of its face.

On a reverse fan the blades are curved the opposite way, so the fan pushes air in the direction its front face points rather than pulling it through from behind. The visible side becomes the intake side. That means the finished, lit face of the fan stays toward the viewer while the airflow still travels the way the build needs.

The reverse design is aimed at bottom intake positions and power supply shroud mounts, the two places in a vertical case layout where a conventional fan has to face away from the glass. Fitted here, the fan feeds fresh air upward over the graphics card while its front face and lighting remain on show.

Speed is set by the motherboard over a 4-pin PWM connector, ranging from 800 to 1600 RPM within a 10 percent tolerance. Bottom intake fans often run quieter than top exhaust fans in a tuned build, and the wide range means the same fan can hold a low, steady feed of air or be pushed hard when temperatures call for it.

Maximum airflow is 44.35 CFM with a 10 percent tolerance. Mounted as bottom intake, that volume travels straight up into the underside of the graphics card, which is where the hottest air in a modern build tends to collect. Fresh air arriving there does more for temperatures than the same fan would achieve as an extra exhaust.

Maximum static air pressure is 1.42mmH2O. Bottom intake positions almost always sit behind a removable dust filter, which is exactly the sort of restriction that robs a low-pressure fan of its rated airflow. This figure is what allows the fan to keep pulling a useful volume through that filter rather than stalling against it.

The fan is specified at a maximum of 31.21dB(A), reached only at its full 1600 RPM. Fans mounted low in a chassis usually sit closer to the floor and to hard surfaces that reflect sound back into the room, so a modest ceiling matters more here than it does for a fan tucked behind a front panel.

Lighting is arranged in two zones: eight addressable LEDs in the centre hub and sixteen around the outer ring, twenty-four in total. Because a reverse fan shows its lit face to the window, both zones stay visible in a shroud or floor mount, where a standard fan would only present its motor housing and support struts.

The fan uses the common 5V 3-pin addressable header and works with Aura Sync, so it shares one lighting profile with the rest of the components in the build. Mixed standard and reverse fans from the same range can therefore run identical effects, which keeps a shroud row visually consistent with the front intake fans above it.

Eight rubber pads sit between the fan frame and the case. In a floor or shroud position the fan is bolted to a large flat steel panel, which is the ideal shape to amplify motor vibration into audible buzzing. Isolating the two surfaces stops that transfer and keeps the mounting from loosening over months of running.

The rotor turns on a hydraulic bearing rated at 30,000 hours mean time between failures. Electrically the fan is rated and tested at 12V, drawing 0.15A up to a 0.18A maximum for 1.8W of power and a 2.16W peak, and it starts turning from 5V so it recovers cleanly from the bottom of an aggressive fan curve.

Both leads are 500mm long, one 4-pin PWM power cable and one 3-pin ARGB cable, each with male and female ends for chaining fans together. Screws are supplied. Half a metre of cable is useful in a floor mount, where the headers are usually at the top of the board and a shorter lead would need an extension.
