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.
Water cooling parts are designed for self-installation by qualified users. Damage caused by installation error isn't covered — if you're unsure at any step, ask before you power the loop.
About this part
This N-RTX3090H-X-V2 full-coverage block directly cools the video card core (GPU), graphics memory (RAM), and voltage regulator modules (VRM). By directly cooling these components, you can achieve great temperatures and reach higher overclocks while extending the overall lifespan of your card by running at lower temperatures.
A high-flow design allows multiple blocks to run in series. The block can be configured as parallel or serial designs. In multi-block setups, an additional bridge may be needed, depending on your setup.
In the box

- (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-RTX3090H-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 cancelled 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. Damage caused by installation error is not covered.
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 $233.99 — 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.
Ask about compatibility
Having trouble finding a compatible block for your card, or not sure your card works with this one? Send us your card model and we'll check it for you.
We'll email you back within two business days.
