EK-XRES 100 Revo D5 PWM Glass is a High-Performance water cooling pump with integrated reservoir. The core of the unit is the market-proven Xylem D5 PWM water pump. This unit offers increased hydraulic performance (up to 15 %) compared to original Xylem D5 PWM. EK-XRES 100 Revo D5 Glass series reservoir tube is made out of high-quality borosilicate glass and this is the first differentiation from non-glass Revo reservoirs. The second is pre-installed central Stainless Steel pipe that serves as a suction point - pipe is hollow and is feeding the pump with liquid - and holds the top and bottom together. The tube is threadless and is not compatible with other Revo products. As with other Revo D5 series products, Glass variant features a fully rounded design thus offering greater usability, allowing installation at any angle within 360° of rotation. The special rubber shock absorber is used to de-couple the main pump body from the mounting clip for silent operation, free of vibration induced noise. Reservoir's top features three ports, three G1/4" threaded ports, which are intended as fill port. Any of the top ports can be also used as an inlet port in that case EK-Extender M-F G1/4" must be used. Both, top and bottom, are made of quality POM Acetal material. Additionally, a PU anti-vortex foam is enclosed and can be used to reduce excessive vortex issues. This reservoir pump combo unit can be mounted directly on the computer chassis by using enclosed Revo D5 Holder.
