The HEATKILLER D5 PWM aRGB pump combines legendary reliability with state-of-the-art technology and impressive lighting. Developed for demanding water cooling enthusiasts. Original Xylem D5 PWM - Reliable, powerful, and quiet At the heart of the HEATKILLER D5 aRGB is an original Xylem Lowara D5 pump. A pump mechanism that has proven itself over decades. Its patented designstands for maximum service life, high delivery rate, and silent operation. WPI Watercool Pump Interface - One cable, all functions The Watercool Pump Interface (WPI) is the central interface for connecting HEATKILLER D5 PWM pumps. In addition to the supply voltages, PWM, RPM, and aRGB signals are also transmitted via a single cable. This makes cable Routing compact and elegant. Ideal in combination with Passive Control for the MO-RA IV series. The pump can also be connected to a conventional motherboard using the included cable, regulated, and the aRGB LEDs controlled. The pump can also be connected to a conventional motherboard using the included cable, allowing you to regulate it and control the aRGB LEDs. Shiny aRGB effects - flawless, uniform lighting Sixteen individually controllable aRGB LEDs in combination with original PLEXIGLAS GS LED provide impressive lighting effects. This acrylic distributes the light homogously and prevents annoying light spots.
