Cautions & Warnings

When Installing

1.Make sure that the power source’s output voltage and frequency are compatible with the power input requirements of the water pump before installing. (Input voltage and frequency of the water pump can be located on the box and sink cover.)

2.Do not place in dusty or humid conditions, under direct sunlight, or near a heat source such as a room heater.

3.Do not drop or subject to excessive force.

4.Check CPU socket compatibility first.

5.Familiarize yourself with this manual.

6.Do not mix any contaminant with the coolant when filling, for it may cause product failure.

7.Use of a multiple-outlet power strip is recommended, for you can connect or disconnect power to the PC and the Reserator 1’s pump simultaneously.

When in Use

1. Always turn on the water pump first before using the system.

2.If the coolant isn’t circulating or the pump is making a strange noise, turn off the pc system immediately.

3.Do not place any object on the product.

4.Install on a flat surface with no vibration or slant; do not tilt or lay horizontally.

5.Use distilled or tap water for coolant, regularly check the amount of coolant, and replenish as needed.

6.If a leak is found, turn off the system immediately and examine the problem before using the system again.

7.If the system will not be used for an extended period of time, turn off the water pump.

8.When moving the system, separate the reserator from the PC case before moving.

9.Make sure to not let any air bubbles into the Water Block and tubes while in use.

10.Always check that the water pump is properly functioning.

Zalman Noise Prevention System











1. Features

Reserator 1 is designed with an optimal heat dissipation area based on Zalman Tech’s HCET (High Capacity Extrusion Technique) and high efficiency cooling technology. As a result, this product achieves excellent cooling performance even with natural convection, making it the world’s first fanless, noiseless watercooling system. The reservoir, radiator, and the water pump are conveniently integrated into one assembly, and the heatsink is anodized to prevent corrosion and rust. In addition, the kit includes the high-performance ZM-WB2 Gold water block which is not susceptible to galvanic corrosion. 3


1.1 Reserator (Reservoir + Radiator + Water Pump)

Reserator is a compound word derived from ‘Reservoir’ and ‘Radiator’- it acts as a reservoir while radiating heat. This product works well with natural convection and integrates a water pump inside for convenience.

1.2 CPU Water Block(ZM-WB2 Gold)

The system includes Zalman’s new CPU cooling component,

ZM-WB2 Gold, which performs superbly and installs easily.

1.3 Flow Indicator

This component is connected in-line with the circulation tube to check the circulation of the coolant. When the coolant is actively circulating, the cap inside the flow indicator shakes rapidly, providing easy indication of the circulation status.

GPU Water Block

Water block for cooling the GPU on a graphics card. This product is sold separately and available in two versions for compatibility with ATI Radeon and NVIDIA GeForce GPUs.

ZM-WB2 Gold

Dual CPU users can buy an additional unit of ZM-WB2 Gold for installation on the second CPU.

Silicone Tube

If the included silicone tube is found to be short or you need to use the tube on another system, additional tubes can be bought separately

(base length is 3 m, 12 x 8 mm).

Heatpipe HDD Cooler

This component cools the heat generated from the hard disk drive and reduces the vibration that is passed on to the system case.

Power Supply Unit

By implementing heat-sensor circuitry that controls the cooling fan’s speed in relation to the temperature within the power supply, emanating noise has been greatly reduced, making this component suitable for noiseless systems.
