About this part

This N-GV5090DWF-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.

Bykski Armored End Port GPU Waterblock with Backplate

I picked up this block for my Gigabyte Gaming OC 5090 initially because it was the only one I could find for this card and really liked the ports being on the end of the card instead of the front.

Once i received the block and inspected it i was very impressed with the build quality and the material finish, its a great looking block and has a size that could even work in SF builds. No instruction were included but it was easy to find on the website and simple to follow. Everything you need was include in the package although i wish they came with pre-cut thermal pads, but no manufacture seems to offer this with their blocks.

Once installed the block has been performing as expected. I have used many blocks 0ver the years from EK, Alpahacool and Bitspower, mostly EK as I thought they were the best available. This is my first Bykski water block and I feel like I have been wasting my money on the over priced EK products. This block has performed just as good as any other brands I've tried with temps staying in the mid to low 40s under load which is 15 degrees below what the standard aircooler was sitting at underload in my case.

I can easily recommend this block, it performs well, looks great and at a reasonable price

Before you install it

This is a component, not an assembly — how it goes in depends on the loop it is joining. What does not change is the last step: 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.

Is it in stock, and when will it ship?
Yes — in stock 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?

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.
