EK-Quantum Vector XC3 RTX 3080/3090 D-RGB GPU Water Block
User Guide
Basic Guidelines
Before using this product, follow these guidelines:
- Read the manual carefully before installation.
- Remove your graphics card from the computer for safe mounting to prevent damage.
- EK Fittings require minimal force; the seal is ensured by O-ring gaskets.
- Use quality, market-proven corrosion-inhibiting coolants.
- Do not use pure distilled water; EK recommends EK-CryoFuel Coolants for best results.
- Bleed air thoroughly from your water block for optimal performance.

Installation Guide
Step 1: Preparing the Graphics Card
Option 1 (No Backplate): Use a Phillips head screwdriver to remove eleven marked screws and the Stock Cooler Backplate. Do not remove the I/O Bracket screw. Detach the PCB from the stock cooler and disconnect cables.
[!] Remove stock cooler slowly; it may be glued with thermal pads.
Option 2 (With Backplate): Use a Phillips head screwdriver to remove twelve marked screws and the Stock Cooler Backplate. Detach the PCB from the stock cooler and backplate, and disconnect cables.
[!] Remove stock cooler slowly; it may be glued with thermal pads.
Step 2: Cleaning the PCB
Wipe off original thermal compound with a nonabrasive cloth or Q-tip until clean. Use denatured alcohol for stubborn residue. Remove all stock thermal pads from the PCB.
Step 3: Cutting and Placing Thermal Pads
Cut Thermal Pad F 1.0 mm (120 x 16 mm) into smaller pieces to cover VRM components (COILs, MOSFETs, drivers).
[!] Remove protective foil from both sides of the thermal pad before installation.
Place cut thermal pads on the PCB as illustrated.
Step 4: Applying Thermal Compound
Apply enclosed EK-TIM Ectotherm thermal grease thinly and evenly on the CPU heat spreader (IHS).
[!] Excessive or uneven application can lead to poor performance.
Step 5: Installing the Water Block
Placing the Block: Position the water block with standoffs onto the graphics card, aligning mounting holes.
[!] Do not use excessive force when pressing the block down, as chip dies are fragile.
Attaching the Block: Use thirteen (13) M2.5 x 4 AX1 screws and M2.5 PVC washers. Tighten screws evenly, starting from the GPU core outwards. Always use a plastic washer under each screw.
Attaching the I/O Bracket: Use two (2) M2.5 x 6 AX1 screws and one (1) M2.5 nut to secure the I/O bracket to the PCB.
Step 6: Inserting the Graphics Card into the Chassis
Carefully lift the graphics card with the installed water block and insert it into the motherboard's PCIexpress expansion slot. Note that the card will be heavier.
[!] Handle the graphics card with extreme care to avoid damaging the card or water block assembly.
Step 7: Installation of Fittings and Tubing
Screw in two (2) G1/4 threaded male fittings. Attach liquid cooling tubes and connect to the cooling loop.
[!] Plug the remaining two openings with EK-Plug G1/4 or equivalent.
Any opening can be used as an inlet/outlet port.
EK recommends using EK fittings with EK water blocks.
[!] CAUTION: For non-EK fittings, ensure the male G1/4" thread length does not exceed 5mm.
Step 8: Connecting the D-RGB LED Strip
Plug the 4-pin D-RGB connector from the water block into the motherboard's D-RGB Header. Ensure the header pin layout is: +5V, Data, Empty, Ground.
[!] Incorrect installation can damage the LED strip or header.
Testing the Loop
Perform a 24-hour leak test to ensure successful installation. Connect the pump to a PSU outside the system. Turn on the PSU and let the pump run continuously without powering other components. Inspect for leaks, fix if found, and repeat testing. Ensure all hardware is dry before powering on the system.
Checking for Contact in Case of High Temperatures
If needed, temporarily remove the water block to check for uniform surface contact, especially on the VRM section. Re-attach the block if contact is good, or repeat previous steps. If contact is poor, re-check or contact support at https://www.ekwb.com/customer-support/.
