1 Chapter Introduction User Manual 1
Congratulations on your purchase of a Koolance system! As the most sophisticated product of its kind, Koolance offers many unique features found nowhere else in the realm of computer cooling. In addition, you can expect to enjoy all of the advantages that water-cooling technology brings with it. Advantages of Water Cooling Water transfers 30 times faster, and holds over 4 times more heat than air.
The heart of a liquid cooling system is the pump. This device pushes liquid through each cooler and into the heat exchanger. Koolance systems use dual pumps to increase reliability and liquid pressure. If one pump should fail, the second can help prevent potential damage caused by heat increase. Every Koolance system includes built-in hardware safety features.
Exos-2 System Diagram Reservoir & Pumps Radiator Cooling Fans Reservoir Refill Plug LED Display Panel Coolant Inlet Coolant Outlet Power Connection Reservoir & Pumps - The coolant tank is translucent for easy liquid-level monitoring. Dual pumps help to provide higher system reliability; if one pump should fail, the other can maintain flow, gradually bringing the system to shut itself down (see LED Display Panel).
LED Display Panel ! CAUTION: Exos-2 systems allow full user control of hardware safety settings, such as audio alarm and shutdown. Please be sure to configure your LED Display Panel properly, or damage to your computer and equipment could result. Decrease Fan Speed Sensor Channel Increase Fan Speed Temperature Value Cycle Sensor Channels Display in ºC or ºF Temperature Sensors Exos-2 systems can monitor up to 3 temperature sensors (included).
Alarm Settings By default, the Koolance audio alarm will sound if any sensor reaches 55ºC (131ºF). When the system alarm sounds, the LED temperature will flash in the display and the radiator fans will increase to 100% power. To change this setting for an individual sensor, choose the desired channel with SET, and press and hold ▲ + ▼ together for 3 seconds. The alarm temperature will begin flashing. You may change this value from 0ºC (32ºF) up to 99ºC (210ºF).

Positioning the Exos The Exos is designed to operate in various locations, but it must run upright. Air filtration is not possible in all orientations. If the Exos can not be placed adjacent to the computer, it can be moved farther away. Depending on heat load, 3-6 feet (12 meters) should be an acceptable distance for most Exos configurations. Extra tubing can be purchased from Koolance.com or your local reseller. Rubber foot pads are included to place the Exos on or near your computer chassis.
External Nozzles & Power Cable Cut the included 10mm (3/8”) tubing into two segments. You will need to connect each to the Exos’ rear nozzles. Each tubing connection uses a threaded compression fitting (“hose screw”) to keep it secure. To connect these components, first thread a hose screw onto the tube end. Squeeze the tube while pushing it firmly over the nozzle. Tubing should completely cover the nozzle. Tighten the connection by sliding the compression fitting down over the nozzle and screwing securely.
Connecting the Slot Adapter The Slot Adapter allows the Exos-2 to connect with any ATX computer through an available card slot. It is responsible for both input and output tubes, along with the external power cable connection. This prevents the computer chassis from requiring any modifications for the cooling unit.
Installing the Slot Adapter Install the Slot Adapter into any available rear card slot in your computer. Screw the Slot Adapter in place as you would a normal device. From the rear of the case, carefully feed both ends of the liquid tubing through the Slot Adapter and into the chassis. Plug the other end of the Exos’ external power cable into the Slot Adapter.
Power Connection The Exos-2 requires approximately 11-17W from any standard ATX power supply. Since it is adapted internally, it does not need a dedicated external AC power cable. Connect the Slot Adapter’s main power plug (12 Volt 4-pin Molex) to the computer’s power supply. Without this important connection, the Exos-2 will NOT operate. ! 12 CAUTION: The Power Connection is vital to system operation.
ATX Power Switch The ATX “pass through” lead is responsible for shutting off your computer if sensor channel #1 reaches 3ºC (5ºF) above the preset alarm temperature (See LED Display for alarm configuration). Connect the male ATX power lead from the Slot Adapter to the chassis main power button. To Motherboard To ATX Power Button Connect the female ATX power lead from the Slot Adapter to the motherboard’s power switch connection (often marked “PWRSW”, “PWSW”, or “PWBT”).
Cooler & Tubing Configuration Depending on the cooling blocks (“coolers”) in your Koolance system and nozzle sizes (1/4”, 3/8”, etc.), they may be connected in series, parallel, or a mixture of both for best performance. Recommended configurations are illustrated below. If you are comfortable experimenting with different tubing setups, there may be more optimal configurations for your particular system. NOTE: For simplicity, tubing ID (internal diameter) will be listed in metric units.
Parallel Systems Koolance coolers which are 6mm (1/4”), such as the GPU-180-L06 video cooler or HD-40-L06 hard drive cooler, can still be effectively used in Exos-2 series systems. Using a parallel tubing configuration with hose splitters will help maintain coolant flow rate through these systems.
Disconnecting Hoses Nozzles are designed to attach tightly. If you need to remove a hose for any reason, it may not pull off easily, even after unscrewing the compression fitting. Usually, a connection will come free by squeezing the hose on top of the nozzle and pulling away. If this fails, cutting a small incision lengthwise (parallel) along the nozzle should free it. When a hose screw has been removed, it may have distorted the tubing beneath it.
Hose Lengths Before installing your liquid coolers, appropriate lengths of tubing must be cut to connect each device. It is generally easier to estimate the required tubing amounts with installed computer hardware. On the rear of the Exos, the nozzle to the left is the outlet of the radiator. The right nozzle is the inlet. Generally, the outlet will connect first with your CPU Cooler.
Continue connecting all of your coolers in the system until there are no longer any open tube ends. Liquid Coolers You should now install the liquid coolers (CPU, GPU, Hard Drive, etc.) to your hardware before continuing this User Manual. Please refer to your cooler kit’s individual installation instructions, then continue on to the next section.
3 Chapter Filling & Maintenance User Manual 19
Testing & Filling Once all of the coolers have been connected, the system can be filled with coolant. The refill plug is located on top of the reservoir. Remove the large slot-headed screw (with a screwdriver or large coin) and insert the refill funnel. ! WARNING : The liquid coolant is electrically conductive. Use caution when filling the system, and keep all liquids away from computer hardware and power cables. In case of emergency during installation, immediately unplug the computer’s rear power cable.
Because of gravity, the Exos must be placed above all internal cooling components while being filled. Otherwise, coolant will exit the refill tap once the reservoir is full. ! CAUTION: When filling, the Exos must be higher than all internal liquid coolers, or coolant will exit the refill tap upon filling. Replace the refill plug screw. The cooling system can be “jump-started” to assist in the circulation process without booting-up the computer.
Draining & Maintenance The coolant in your system should be emptied for any of the below reasons. Unless replacing the liquid coolant, it can also be reused. 1. To Keep it Clean - Koolance recommends replacing the liquid coolant about every 2 years. The coolant should also be replaced if it becomes contaminated or significantly changes color. 2. Upgrading Coolers - Whether you are adding or removing liquid coolers, upgrades can be performed more easily with a dry system. 3.
Troubleshooting Your Koolance system is designed to provide years of reliable cooling. To help avoid unnecessary product returns, we have prepared this list of possible operational problems, and their most common solutions. 1. How do I tell if the pumps are working?... After inital air-filtering, the pumps may not create enough noise to tell if they’re working properly.
4. After the system has been on for a while, the temperature alarm sounds... Make sure the LED temperature is at or above your preset alarm temperature (default is 55ºC, 131ºF). If not, the audio alarm may in fact be your motherboard’s BIOS alarm. If the system is not exhibiting signs of overheating (see #2 in Troubleshooting), this temperature monitor may need to be disabled to ignore false readings by BIOS. The Koolance LED temperature will flash whenever the cooling system alarm sounds.
6. My system appears to be leaking fluid... Since users are allowed to configure their own coolers and clamps, it is possible a connection was not properly sealed (however unlikely). If you can see liquid somewhere on the tubing, or at the bottom of the chassis, computer components may need to be removed for a system test (see Flow Testing). If liquid should get onto another computer component, shut down the system, and remove the component. In many cases, the hardware will be fine after allowing it to dry.
