EVGA RTX 3080 12GB Hydro Copper Overview

The EVGA GeForce RTX 3080 12GB XC3 Ultra Hydro Copper is a factory water-cooled graphics card built for custom liquid-cooling loops. It carries 12GB of GDDR6X memory and a real boost clock of 1755 MHz. A full-cover copper waterblock cools the GPU, VRM and memory directly. An all-metal backplate and adjustable ARGB lighting complete the premium design.

Ideal For Custom Loop Builders

This card suits enthusiasts who already run an open custom loop and want a pre-installed full-cover block without the effort of mounting a third-party kit. The LHR designation limits Ethereum hash rates, so dedicated miners should look at non-LHR alternatives instead. Buyers planning air cooling or AIO-only builds cannot use this model because it has no integrated fans or radiator.

Loop Compatibility Checklist

Verify that your loop uses standard G1/4 thread fittings and that your reservoir and pump provide enough flow for the additional restriction of a full-cover GPU block. Confirm the physical slot width fits your case and motherboard spacing when the block is installed. Ensure your power supply carries the required PCIe connectors for a 3080-class board. Check that your coolant and tubing choices are compatible with copper and nickel plating.

Questions about this item

Do I need a custom water-cooling loop with a pump and reservoir to run this Hydro Copper card?

Yes, the full-cover waterblock requires an external loop to cool the GPU, VRM and memory.

Can I keep my DisplayPort 1.4a monitor while using the HDMI 2.1 port for a newer display?

Both interfaces are present, so the older monitor and a newer screen can be driven simultaneously.

How do I confirm the 1755 MHz boost clock is active after installation?

Check the real-time frequency readout in GPU-Z or EVGA Precision X1 while a 3-D load is running.
