Alphacool DC-LT 2 2600rpm Ceramic 12V DC pump 1019580

Alphacool DC-LT 2 12 V pump for silent loops

The Alphacool DC-LT 2 is a 12 V DC pump built for computer water cooling systems where low noise matters more than raw flow. Its ceramic axle and magnetically suspended impeller run on a true three-phase sinusoidal controller at 2600 rpm. The design targets small to medium loops that need to stay virtually inaudible.

Builders who prioritise silence over maximum flow

This pump suits compact or mid-sized custom loops and GPU all-in-one units where any mechanical hum is unacceptable. It is not for high-restriction circuits with many blocks and radiators that demand higher pressure, nor for builders who need PWM speed reporting or a standard fan header connection.

2600 rpm ceramic-axle motor on 12 V DC

The motor spins at 2600 rpm using a ceramic axle and dual-magnet impeller driven by a sine-wave PCB, a combination that removes bearing noise almost entirely. That specific speed and bearing choice determine whether the pump can deliver enough head pressure for a given loop without becoming audible.
