Connecting the Tubing

The diagram shows the general layout of the cooling loop. For optimal performance, connect the radiator's outlet to the water block's inlet.

Steps:

1. Visualize the tube routing within the chassis. Measure the required length, adding 2-3 cm for spare.
2. Cut the tubing to the measured length.
3. Remove the fitting rings from the compression fittings by rotating them counter-clockwise.
4. Slide the fitting ring onto the tube, threaded side facing the fitting barb.
5. Attach the tube onto the fitting barb. Heating the tube in warm water can help.
6. Slide the fitting ring towards the barb and tighten it clockwise to secure the tube.
7. Repeat for all fittings to complete the loop. Ensure tubes are not bent or twisted.

Electrical Connections

Connecting the Pump-Reservoir Unit

1. Step 1: Connect the 4-pin Molex male connector from the pump to the power supply's Molex connector.
2. Step 2: Connect the 4-pin female connector from the pump to the motherboard's CPU-dedicated fan header for optimal PWM regulation.

Connecting the Fans

1. Step 1: Connect the female connectors from the fans to the male connectors on the EK-Cable Y splitter.
2. Step 2: Connect the EK-Cable Y splitter connector to the motherboard's fan header, preferably a CPU-dedicated one.

Recommended Filling and Leak-Testing Procedure

Mandatory Steps:

1. Disconnect all PSU power connectors (4/8-pin ESP, 24-pin ATX, PCI-express power, SATA power) from your computer.
2. Plug the EK-ATX Bridging plug into your 24-pin ATX PSU cable to allow jump-starting the computer.

This procedure requires only the pump to be connected to the PSU. All other components should be disconnected.

This prepares the system for filling the loop with coolant and running a leak test.

Connecting the Fans, Pump and CPU LED Lights

Step 1: Plug the 4-pin RGB LED connectors from the water block and fans into the motherboard's RGB_HEADER. Ensure the pin layout is +12V G R B and the arrow on the connector aligns with the +12V line on the motherboard. Failure to do so can damage the motherboard or LED strip.

Filling the System for the First Time

Step 1: Preparing the Cooling Liquid

Mix 100mL of coolant concentrate with 900mL of distilled water in a mixing bottle. Ensure proper mixing before pouring into the loop. Store any remaining mixture in a PET bottle, not a food or beverage container.

Step 2: Filling the Reservoir

Remove the reservoir's top cover. Place paper towels around exposed hardware as a precaution against spills. Pour the pre-mixed coolant into the reservoir until the level is about 2 centimeters below the top.

Step 3: Initial Power-On and Check

Verify that the EK-ATX Bridging plug and EK-Cable Pump Testing Adapter are correctly connected. Turn the power supply on briefly to check that only the pump is running.

Running the System

Step 4: As the power supply runs, coolant should be pushed from the reservoir through the loop. Continue filling the coolant while the pump is running. Alternatively, cycle the power supply on and off in short intervals to speed up air bleeding. Once the coolant level stabilizes, top it off to about 2 centimeters below the reservoir's edge and screw the top back on.

Step 5: Gently shake and tilt the PC chassis to remove any trapped air in the radiator. Add more coolant if necessary.

24 Hour Leak Test

It is recommended to run the pump for at least 24 hours to ensure the system is leak-free. After a successful leak test, connect all necessary cables to the motherboard, graphics card, and expansion drives. The ATX Bridging Plug is no longer needed.

Draining of the Loop

Before disassembly: Turn off the computer, unplug the power cord, and place paper towels around the hardware.

1. Step 1: Unscrew the M4 nuts securing the EK-UNI Pump Bracket on the PC chassis. Carefully pull the pump-reservoir unit and bracket out of the case. Do not disconnect tubing yet. Place a container under the pump-reservoir unit.
2. Step 2: Unscrew the fitting ring on the outlet port of the pump-reservoir unit counter-clockwise. Gently pull the tube off the fitting and direct it into the container to drain the coolant.
3. Step 3: Disconnect the other tube from the inlet port. Direct one tube into the container and blow into the other to help drain the system. Tilt the unit or remove the top cap to pour out remaining coolant. Keep disconnected tube ends over paper towels to prevent spillage. Dry tubes and reservoir.

Possibilities of Expanding the System

Custom water cooling loops can be extended almost without limitations. For maximum performance, use at least one 120mm radiator section per water-cooled component plus one spare. For example, cooling a CPU and a GPU typically requires at least a 240mm radiator, ideally a 360mm radiator.

This guide focuses on expanding the loop with an additional GPU water block, but additional radiators, reservoirs, or motherboard blocks can also be added.

Steps for Expansion:

1. If the system is already filled, drain the loop according to the 'Draining of the Loop' instructions.
2. Install the new component according to its specific manual. Position it to ensure water blocks receive the coldest coolant possible.
3. Determine optimal tube routing and install compatible fittings (e.g., 10/13mm) and plugs.
4. Measure and cut tubing, attach it to fittings, and secure with compression rings.
5. Fill the system following the 'Filling the System for the First Time' steps.

Maintenance

To ensure optimal performance throughout the product's lifespan, follow these maintenance tips:

• TIP 1: Dust Removal: Remove dust every 2-3 months using a vacuum cleaner or compressed air, paying special attention to the radiator. Turn off and unplug the computer before cleaning.
• TIP 2: Checking Electrical Components: Annually check that the pump and fans are running correctly and silently, reacting to PWM duty cycle changes.
• TIP 3: Cleaning the Unit: Annually drain the coolant, flush the radiator, and clean/check the pump. Consider changing the tubing.
• TIP 4: Use EK Designed and Manufactured Parts Only: Using genuine EKWB parts prevents performance, compatibility, and warranty issues.

Frequently Asked Questions

Q: Is this kit compatible with narrow server type LGA-2011 motherboards? How about older LGA-1366 and -755?

A: Narrow server type LGA-2011 is not supported by default; a specific mounting plate (EK-Supremacy LGA-2011 Narrow ILM) is required. For LGA-1366 and LGA-775, follow the AMD® socket installation manual, removing the inner core of the CPU backplate rubber gasket.

Q: How many water blocks can be added to the loop?

A: The EK-KIT RGB can be upgraded with additional parts. For reasonable performance, it's recommended not to exceed one GPU water block for the EK-KIT RGB240 and two for the EK-KIT RGB360. The pump can manage up to 4 GPU water blocks, but an additional radiator is needed.

Q: What flow rates are expected with EK-KIT RGB?

A: The kit typically operates at about 440L/h. Adding a GPU water block may reduce this to around 300L/h. For best performance with multiple water blocks, run the pump at 100% duty cycle.

Q: Can the Push-Pull Fan configuration be used with EK-KIT RGB?

A: Yes, additional fans can be mounted on the bottom for push-pull. UNC 6-32x30mm screws (purchased separately) are required for standard 120x120x25mm fans.

Q: Is it possible to 'daisy-chain' the enclosed PWM splitter?

A: Yes, the splitter allows daisy-chaining of additional PWM splitters, provided the total power draw does not exceed 12W (1A on +12VDC), which is the limit for a 4-pin fan header.

Troubleshooting

In Case of CPU Overheating:

High CPU temperatures may indicate a malfunctioning liquid cooling loop. Check for:

• Malfunctioning water pump: Look for rapid temperature spikes. Ensure the pump is connected and liquid is flowing. Feel for vibration.
• Malfunctioning cooling fans: Look for rapid temperature spikes. Ensure fans are connected and rotating.
• Kink in the liquid cooling tubing: Thin tubing can collapse, restricting flow. Check for kinks.
• Clogged microchannels in the water block: Impurities can clog channels, reducing flow and increasing temperature. Inspect water block internals.
• Improper thermal interface material (TIM) application: Too little or too much paste can cause overheating. Refer to the water block installation section.
• Cooling liquid freezing: Avoid subzero temperatures. Ensure ambient temperature is above 5°C.

Overheating can also be due to CPU issues:

• Poor thermal contact within the CPU: Some CPUs have inherent poor thermal contact, leading to higher temperatures even with proper cooling. Replacing TIM or de-lidding (advanced) may be necessary, but voids warranty.

For further assistance, consult the EK knowledge base at http://support.ekwb.com or contact EK Support.

The Cooler is Too Loud:

EK-Vardar fans may run at high speeds if the UEFI/BIOS fan control is not set to PWM mode. Ensure fan control is set to PWM (not DC) in the motherboard's 'Hardware Monitoring' section. Consult your motherboard manual for specific settings (ASUS, ASRock, Gigabyte, MSI examples provided). Ensure the 4-pin PWM fan connector is correctly plugged into the motherboard's fan header.

General Liquid Cooling Parts Cleaning Guide

Disassembly for cleaning is permitted, but voids the EK leak-free guarantee.

• Cleaning bare copper: Use slightly acidic agents like diluted vinegar or lemon juice. Cola, ketchup, or mustard can also be used. A 5% vinegar solution can kill 99.9% of algae. Flush with water and rinse with distilled water. Copper may naturally tarnish.
• Cleaning nickel plated copper: Do not use aggressive chemicals or rough materials. Clean with a wet, non-abrasive cloth and rinse with clean water. Use automotive metal polish for shine. Rinse with distilled water after polishing.
• Cleaning acrylic (plexi) glass tops: Use only warm, soapy water and a toothbrush. Avoid alcohol, acetone, or aggressive chemicals, which can damage acrylic and void the warranty.
• Cleaning POM (acetal) tops: Use soft cloth and warm, soapy water. While POM can withstand some chemicals, use them sparingly. Rinse with distilled water.

Preventive Steps

1. Use corrosion-inhibiting coolant (e.g., EK-Ekoolant) to prevent algae growth and dirt deposition.
2. Avoid Copper Sulphate based additives to prevent tarnishing of internal components.
