Zyvpee DA02507S05HA 25mm 5V 0.18A 2-wire case fan

Compact 25 mm DC cooler

The Zyvpee DA02507S05HA is a 25 mm square case fan built for mini devices that need active airflow in very tight spaces. It runs on a 5 V supply drawing 0.18 A through a simple two-wire lead, so it can be powered directly from a low-voltage header or a small DC source. The non-LED black frame keeps the unit visually neutral inside compact enclosures.

Capacity and headroom

At 25*25*7 mm the fan fits where larger coolers cannot, delivering a modest air stream suited to low-power boards, embedded modules or small-form-factor appliances. The 0.18 A draw limits total heat-moving capacity, so it will not cope with sustained high-wattage loads or multi-core processors under full load. It is not for builders who need more airflow than a 5 V micro-fan can provide.

Build and daily use

The two-wire DC connection means speed is fixed unless the host varies the voltage, so there is no PWM signal wire for automatic curve control. Mounting holes follow the 25 mm square pattern, allowing direct screw attachment to compatible mini-device chassis or heatsink brackets. The plain black plastic housing and lack of lighting suit embedded or headless deployments where silence and simplicity matter more than aesthetics.
