GAMEMAX GMX-WFWT-PWM 120mm Case Fan - White Frame / High-Performance Cooling Fan / PWM Intelligent Speed Control (800–1600 RPM) / Ultra-Quiet Operation (Max 30dBA) / 8× Shock-Absorbing Rubber Pads / 4-Pin Motherboard Control for Automatic Speed Adjustment / Durable & Stable Design for PC Cases / GMX-WFWT-PWM

The Gamemax GMX-WFWT-PWM is a standard 120 x 120 x 25 mm case fan in a white frame, driven by a 4-pin PWM connector. It fits the mounting points found in nearly every ATX and micro-ATX case, so it drops into an existing build as an intake, an exhaust or a radiator fan.

The 4-pin PWM connection lets the motherboard set fan speed anywhere between 800 and 1600 rpm, within 10%. That means the fan idles quietly during browsing and ramps only when temperatures call for it, instead of running flat out constantly as a 3-pin fan on a fixed header would.

Noise tops out at 30 dBA with the fan at 1600 rpm, and falls away as PWM winds it back down. For a machine sitting on a desk rather than under it, the peak figure is the one that matters, because that is the level you hear during a game or a long render.

Maximum airflow is 41 CFM, within 10%, which is the figure that counts for an open intake or exhaust position where air moves freely. Two or three of these moving air through a case is what keeps ambient temperatures down around a GPU and drive cage.

Maximum static air pressure is 1.83 mm-H2O, the specification that determines whether a fan can push air through something dense. Radiators, mesh filters and packed heatsink fins all resist airflow, and static pressure rather than raw CFM is what gets air through them.

The fan runs on a hydraulic bearing with a mean time between failures of 30,000 hours. Hydraulic bearings sit between sleeve and ball designs, staying quieter than ball bearings while lasting considerably longer than a plain sleeve, which is the right trade for a fan that runs whenever the PC is on.

Nine white blades sit in a matching white frame, which suits the white and pastel builds that have become common and keeps the interior looking deliberate rather than assembled from leftovers. There is no LED lighting on this model, so it stays neutral behind a tinted side panel.

Eight shock-absorbing rubber pads sit between the fan and the case, isolating the vibration that otherwise transfers into a steel panel and turns into an audible hum. It is a small addition that often does more for perceived noise than the fan's own rating.

The 4-pin PWM cable is 500 mm long with both male and female connectors, so fans can be chained together off a single motherboard header. Mounting screws are supplied in the box, which means nothing else needs buying to fit it.

Rated voltage is 12 V with a current draw of 0.15 A, rising to a maximum of 0.18 A, which is 1.8 W typical and 2.16 W at peak. It operates across a 5 to 13.8 V range and starts turning from 5 V, so it spins up reliably even on a header set to a low minimum.
