Transfer heat from your CPU efficiently with one of the best water blocks on the market.

[lmt-post-modified-info]

The CPU water block is one of the most vital parts of your loop, transferring the heat from the processor into the liquid. The good news here is that manufacturers all simply have to follow the basic laws of thermodynamics to create effective CPU blocks, so the better brands out there all feature similar levels of performance. Liquid cooling has been shown to be very beneficial when dealing with high wattage components and thanks to the low temps this cooling solution can provide, the longevity of your CPUs life can be extended.

This means that when it comes down to choosing a CPU water block, all you have to concern yourself with is finding one that is compatible and has the desired aesthetics you are looking for.

Let’s take a closer look at the best.

EKWB EK-Quantum Velocity D-RGB, Nickel/Plexi

How we review
Pros
Cons

EKWB is well known for its CPU water blocks, offering a wide variety of styles with impressive aesthetics. The performance is up there with the best but it is this CPU water blocks design that makes it so visually appealing.

The base is nickel-plated copper, allowing for efficient heat transfer into your loop. While this model is specifically for Intel sockets from LGA1150 all the way up to LGA 2066, and while it isn’t universally compatible, it is also available for AMD’s AM4 socket too but you would have to purchase the specific model. The RGB cable is 30cm long and has a 3-pin 5V digital LED header connector.

The all-acrylic top plate allows you to peer into the block and see the water flow but this really comes to life when the D-RGB illumination is operational.

Pros
Cons

The Thermaltake Pacific W7 Plus is an absolutely superb CPU water block. This model comes with plenty of features that are only going to enhance the visual aspect of your next build.

The block now features a transparent chamber to see the liquid doing its thing and this comes with 12 customizable RGB LEDs that make this block look unreal. This block is universally compatible, which means it comes with different brackets to get this working for both AMD and Intel systems. The nickel-plated copper base is designed, like the others, for efficient heat transfer and antic corrosion protection, plus this features a built-in temp sensor.

This narrowly misses out on the top spot, simply because EKWB are a prefered brand but with the universal compatibility, this is a highly sought-after CPU block.

Watercool HEATKILLER IV PRO

Pros
Cons

The Heatkiller IV Pro is an excellent CPU water block and a favorite for many, with excellent performance and a really attractive aesthetic. While the difference in performance to other top CPU blocks is negligible, this comes with a 3°C temperature decrease compared to its predecessor.

The one we have here is for AMD but the block is available for Intel too, just be sure to buy the correct one. The pure copper construction doesn’t really add anything in terms of performance but it looks absolutely sublime.

This is thick, heavy, and can easily make your next water cooled PC look incredible.

Cons

The EKWB EK-CPU Lingum has a unique aesthetic that many are going to love. The walnut finish makes this a masterpiece and works well with the Lingum fittings to produce some quality-looking loops.

This CPU water block is universally compatible, meaning it comes with the needed brackets to fit this with your AMD or Intel setup. The performance, like the others, is exceptional, with a nickel-plated copper base providing efficient heat transfer.

Try something different and go Lingum, it is pricey though.

Corsairs Hydro X range has brought water cooling to the masses and one of the best components in the range is their XC7 CPU Water block.

The XC7 is universally compatible, so you can make this part of your loop regardless if you are going for an AMD or Intel build. The performance is up there with the others, with a negligible difference in temperatures. The base is nickel-plated copper and features more than 60 efficient micro-cooling fins that will easily draw the heat away from the processor.

The XC7 block looks fantastic and RGB illumination makes use of Corsairs iCUE software, making it ideal for Corsair lovers.

Final Word

When it comes to finding the best CPU water block you just need to ensure you buy from a reputable manufacturer. Every block in this round-up has been hand-selected as they all offer efficient heat transfer, with very stylish aesthetics.

The CPU block is a very important part of your loop, so you should always aim to buy from a well-known brand, giving you the reassurance you need to push your CPU to its limits.
