Finding the best GPU water block for your build can be quite tricky. While most of the new graphics card releases are covered, this isn’t for all models, mostly reference cards, and you will often find certain brands only have a block for very specific cards.

That being said, there are a handful of very reputable companies that produce efficient GPU water blocks, much like the CPU blocks, so your choice boils down to aesthetics and compatibility.

The Best GPU Water Block

Aquacomputer Kryographics Next RTX

Editor's Rating

★★★★★ 4.9/5

Pros

Cons

For the enthusiast, Aquacomputer is a go-to brand for water cooling components. They have a strong reputation for producing water blocks and the Kyrographics Next GPU block is another top model.

A stainless steel jet provides optimal cooling performance, while the nickel-plated copper plate transfers heat as efficiently as any other. The design is sublime, with the transparent Plexi top allowing you to peer in and see the flow of your liquid, finished nicely with a black aluminum frame.

This model here is for the RTX 3080 and 3090 but the brand is releasing the same style block for the Radeon 6000-series cards soon.

This block also comes with addressable RGB lighting, with 15 individual LEDs really making this pop in your loop.

The Best GPU Water Block For The RTX 30-Series

Watercool HEATKILLER V

Editor's Rating

★★★★★ 4.8/5

Pros

Cons

Watercool’s Heatkiller V GPU water block does exactly as the name suggests, this is one of the best performing models currently available to water coolers.

The Heatkiller V is mostly composed of copper, with integrated aRGB and a dual-layer flow path. The electrolyte copper base transfers heat every efficiently and the top section I made from Plexi, framed with stainless steel to create a block that is truly spectacular. It is worth noting that this block is only currently available for the RTX 3080 and 3090 but there are a lot of options in a similar design for older spec cards.

With stunning looks and a reasonable price, this is easily one of the best blocks to cool your RTX 3080 or 3090.

EKWB EK-Quantum Vector RE RTX

★★★★★ 4.7/5

Pros

Cons

EKWB may have fallen out of favor with a few enthusiasts in recent years but that doesn’t mean the brand isn’t producing quality components. This GPU block is one of the best looking on this list and still performs well enough to be a high contender.

The Quantum Vector GPU Block shown here is for the reference RTX 3080 and 3090 but they also have options for very specific non-reference RTX cards, as well as some for the Radeon 6000-series. The copper cold plate is going to handle the heat efficiently, although it may not live up to the standards of the Heatkiller above. On top is a combination of Plexi and nickel, giving you a block that is visually spectacular.

Overall, there isn’t a lot bad to say about the EK-Quantum Vector, it is a fabulous water block.

A Great GPU water Block For The Asus ROG Strix & TUF RX 6800/ 6900

Phanteks Glacier G6000 Strix

Editor's Rating

★★★★★ 4.6/5

Pros

Cons

The Phanteks Glacier G6000 is a solid performer and a great option for those looking to cool specific Nvidia or Radeon cards. This model here is for the Asus ROG Strix & TUF RX 6800/ 6900 but it is also available for the Asus ROG Strix 3080 and 3090.

While Phanteks may not have the same brand reputation as the others in the water cooling sphere, they are a company you can trust and are well known for high-quality products. This GPU Water block features a 6mm copper base and delivers a high level of heat dissipation and transfer. The top features a combination of acrylic and aluminium for a really aesthetically pleasing finish that you can peer into and see the flow of your fluid.

Aside from decent performance, you also are getting D-RGB illumination with this block, it’s great.

Editor's Rating

★★★★★ 4.6/5

Pros

Cons

Our last pick comes in the form of this pre-installed GPU/ GPU water block combo from Gigabyte. The Auros Xtreme Waterforce water block is a stunning bit of kit that looks very impressive when vertically mounted.

As this comes with the block attached, this is a very convenient and reassuring option, especially for water cooler who are new to the hobby. The heat transfers efficiently, like any other, through a copper base. This block also features leak detection and the RGB lighting looks absolutely stunning.

Final Word

When looking for the best GPU water block, you only really need to ensure you purchase from a reputable brand. The performance difference among the best block out there is negligible, so the only real challenge comes from finding one for your specific GPU and one that fits in with your planned loop style.

In any case, the water blocks we have shown above are all very efficient at their job and will transfer that heat output without issue, while looking great in the process.
