What installing it actually involves

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

01
Confirm the hardware

This block fits 9 boards:

  • INNO3D NVIDIA 3080 - GEFORCE RTX 3080 ICE DRAGON SUPER EDITION (LHR)
  • INNO3D NVIDIA 3080 - GEFORCE RTX 3080 GAMING X3
  • INNO3D NVIDIA 3080 - GEFORCE RTX 3080 TWIN X2

  • AXGAMING NVIDIA 3080 - GEFORCE RTX 3080 Ti X3W
  • AXGAMING NVIDIA 3090 - GEFORCE RTX 3090 X3W

Match your exact model — not the family.

02
Mount it dry

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

03
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.

About this part

This full coverage block directly cools the video cards core (GPU), graphics memory (RAM), and voltage regulator modules (VRM) on both sides of GPUs. By directly cooling these components you can achieve great temperatures along with the ability to reach higher overclocks or extend the overall lifespan of your card by running at below factory temps.

The block and active backplate are constructed of high purity copper that is electroplated to prevent oxidation. A high flow design is used to allow multiple blocks to run in series. Access to top and bottom G1/4 ports is required on bridge block.

In the box
  • 1x Full Coverage GPU Water Block
  • 1x Active Backplate Block
  • 2x Stop Fitting
  • 1x Mounting Hardware
  • Thermal grease
  • 1x 5v A-RGB (RBW) Light
  • (Warning: Addressable RGB (RBW) is 5V and is ONLY compatible with Addressable RGB (RBW) components. RGB is 12V and is ONLY compatible with RGB components. Mix and match will NOT work and will cause damage.

Bykski cut these to a specific hardware layout, so match your exact model rather than the family before ordering. Part number N-ICH3090-TC.

Is it in stock, and when will it ship?
Yes — only 3 left in Boise, Idaho. Orders placed before 2:00 PM MST on a business day ship the same day — we do not ship weekends or US holidays. Overnight delivery is available at checkout.
Can I return it if it turns out not to fit?
Yes. 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. So we would rather check the fit with you first: send us the model and we will check it against this part.
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 $359.99 — 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.
