127mm 48V Server Cooling Fan

The Zyvpee 127mm case fan operates on a 48V DC input drawing 0.46A through a 4-wire connector. It uses a ball bearing for reliable rotation and measures 127mm by 38mm in a black frame without LED lighting. The unit is built for power cooling in server and inverter environments.

Suited for 48V DC Server Builds

This fan suits technicians maintaining or assembling server power supplies and inverters that require a 127mm 48V component with speed monitoring. It is not for builders working with standard 12V desktop motherboards or anyone needing RGB illumination or PWM control via typical PC headers.

48V 0.46A Electrical Rating Decides Fit

The single specification that decides compatibility is the 48V 0.46A power requirement matched to a 4-wire interface. Only systems designed for this exact voltage and current draw should use this model; connecting it to a 12V header will not work.

Questions about this item

How long will the ball bearing in this 127 mm fan last before it needs replacement?

The ball bearing is rated for long service life in server environments; expect years of continuous operation before any maintenance is required.

What limits sustained performance of the 48 V 0.46 A motor first?

The 48 V 0.46 A input fixes maximum power draw, so the motor winding temperature becomes the limiting factor under constant load.

How much noise and heat does the 12738 produce when running all day?

The 127 mm ball-bearing design runs quietly at full speed; heat output stays proportional to the 48 V 0.46 A draw with no extra thermal spikes.
