About this part

The Bykski N-GV5080GMOC-X-V2 is a full-cover GPU water block with an aluminum backplate, made for builders adding a graphics card to a custom water cooling loop. It fits the GIGABYTE GeForce RTX 5080 Gaming OC 16G, as well as the GIGABYTE GeForce RTX 5080 Windforce OC 16G, the GIGABYTE GeForce RTX 5070 TI Gaming 16GB OC and the GIGABYTE GeForce RTX 5070 TI Aero 16GB OC.

The block draws heat from the GPU chip, the graphics memory and the voltage regulators at once, so the whole card runs cooler than on its stock cooler. The nickel-plated copper base sits under a clear acrylic top with 5V addressable RGB lighting. Standard G1/4 ports let it join a loop in series or in parallel.

Great 5080 water block

I have had this water block on my Gigabyte 5080 for a few months now, and found the installation to be straight forward and relatively easy to do. I especially like the versatility of the input/output ports for cooling tubes. Top notch! The cooler temps are nice, but was it even nicer is the much smaller volume footprint that this water block brings inside your case. I fidn it much more aesthetically pleasing than the giant air cooled solutions out there. Thanks for making a quality product!

What installing it actually involves

Three steps, in the order that matters. The one people get wrong is the first.

Confirm the hardware

This block fits 4 boards:

GIGABYTE NVIDIA 5080 - GEFORCE RTX 5080 GAMING OC 16GB
GIGABYTE NVIDIA 5080 - GEFORCE RTX 5080 WINDFORCE OC 16GB
GIGABYTE NVIDIA 5070 - GEFORCE RTX 5070 Ti GAMING 16GB OC
GIGABYTE NVIDIA 5070 - GEFORCE RTX 5070 Ti AERO 16GB OC

Match your exact model — not the family.

Mount it dry

Thermal interface material as supplied. Even mounting pressure, correct bracket orientation, no over-torquing.

Leak test before power

Run the pump on a bench supply with the rest of the system unpowered. 24 hours is the standard, an hour is the minimum.

Custom water cooling is installed by you, at your own risk. We are not responsible for leaks, or for damage to your parts or system. If you're unsure at any step, ask before you power the loop.

Questions people ask about this part

Answers specific to N-GV5080GMOC-X-V2. If yours isn't here, ask — we'd rather talk you out of the wrong part than sell you one.

What does this part fit?

It is machined for 4 boards:

GIGABYTE NVIDIA 5080 - GEFORCE RTX 5080 GAMING OC 16GB
GIGABYTE NVIDIA 5080 - GEFORCE RTX 5080 WINDFORCE OC 16GB
GIGABYTE NVIDIA 5070 - GEFORCE RTX 5070 Ti GAMING 16GB OC
GIGABYTE NVIDIA 5070 - GEFORCE RTX 5070 Ti AERO 16GB OC

Bykski cut these to a specific hardware layout, so match your exact model rather than the family before ordering. Part number N-GV5080GMOC-X-V2.

Is it in stock, and when will it ship?

It is a normally stocked item currently on pre-order — we are between shipments. Orders dispatch from Boise, Idaho within 20 business days, and pre-orders are filled before any stock goes back on the website.

Can I cancel my pre-order?

Yes. A pre-order can be canceled any time before it ships, for a full refund. Nothing is committed until it leaves Boise.

Will I pay import duties or customs charges on delivery?

Not on a US order. US import duties and tariffs are already included in the price, so nothing is collected at the door and there is no brokerage fee. Orders shipped outside the US may owe that country's customs fees and duties.

Who handles the warranty?

BYKSKI.US, the exclusive US distributor, from Boise, Idaho. Claims are handled domestically rather than returned to an overseas factory. Installation is at your own risk: we are not responsible for leaks or damage to other hardware.

Is shipping free?

Yes — shipping is included at this price for addresses in the lower 48 US states.

Are printed instructions included?

No printed manual is included. Installation references are in the product gallery images, and the install guides on this site cover the process step by step.

Do I need anything else to use it?

A water block is one component of a loop: you also need a pump, a radiator, fittings, tubing and coolant. If you are starting from nothing, an AIO or a distro-plate kit is the shorter route — ask and we will spec it.

Ask us before you order

Send your exact hardware model and we'll confirm the right part before you spend $275.99 — or tell you honestly that this isn't the one.

Returns are accepted within 30 days and are easy to start in the support center. Unopened items can be returned for store credit with no restocking fee; other returns carry a restocking fee, higher for items that have been installed or used.
