Alphacool 12565 Eisblock XPX CPU  

Top 10 Best CPU Water Blocks For I9 3900x,3950x,9900k,

Developed by Alphacool, the Alphacool Eisblock XPX cooler is the company’s latest advancement in the realm of CPU cooling. In comparison with its predecessor, the NexXxoS XP3 cooler, the XPX cooler’s performance has significantly improved. From scratch, Alphacool built a new cooling system, which made this possible.


  • For starters, the fin structure was fine-tuned to a fin count of 81 and a fin thickness of 0.2mm. Water can now flow via a considerably bigger cooling surface. The “Ramp” was invented and patented by Alphacool to ensure that the water was equally dispersed over the cooling fins. It prevents turbulence in the water flow across cooling fins, which would cause unequal water distribution over the cooling fins. 
  • Additionally, Alphacool made use of a dual distributor to reduce resistance. As a result of the ramp, the pump pressure has little to no effect on the cooling performance. You don’t have to sacrifice cooling power to run your system more quietly if you lower the pump’s output.
  • A 34 x 32mm cooling surface area has been added to the bottom of the XPX Eisblock to accommodate CPUs with large DIE, so even massive 10 core CPUs are not an issue.
  • The bracket was also reworked to make it easier to use. New brackets for any type of socket can be simply made if needed in the future. Also, the cooler’s aluminum frames are available in the same colors.
  • For those who want to personalize their cooling system, Alphacool offers a variety of aluminum bodies that can be swapped out for other models in a variety of colors. Color-coordinated mounting kits are also available. There are a variety of color inserts available for the illuminated Alphacool logo.

If you’re looking for the best CPU cooling water block under 100 $ on the market, this is the best method to get your hands on it.

  • Have a variety of aluminum bodies that can be swapped to fit for other models.

Buying Guide

If you want to buy the best CPU water block, then consider following some of the things in mind while buying:

Construction quality

You must first and foremost examine the base plate’s design. Because of this, it will have an impact on the water block’s lifespan. It’s not enough to just look at the inside. Only if both of these are long-lasting will you be able to use the water block for an extended period of time.


The water block must also be compatible with a specific type of CPU. Once you’ve located it, determining whether or not it’ll be useful becomes much simpler. To ensure that installation is not a problem, you must purchase a CPU block that is compatible.

Mounting Hardware

The best option is to buy a CPU block that includes all of the necessary mounting hardware. There is no need to go through the hassle of locating specialized gear. When it arrives, you’ll be able to get started right away. Consequently, the water blocks that come with the mounting hardware should be preferred.

Ease of installation

As a final consideration, take a look at how the software is installed. If it comes with instructions, mounting it on the component should be a breeze. It’s better to buy a water block with instructions on how to use it instead of winging it.


The CPU water block is your first and best bet if your gaming machine requires more cooling than the norm. They can be used in a variety of ways and still provide excellent cooling performance.

If you have a high-end processor that generates a lot of heat and you plan on overclocking, you’ll need a specialized water-cooling solution. Some of the greatest CPU water blocks are available for you to choose from, depending on your needs and your budget.

Identify your needs and available sockets, then choose a water block from the following selection that offers the most value for your forthcoming project.


What is a Water Block in a computer system?

Ans: As a heatsink, a water block is attached to the processor, graphics cards, or the northbridge chipset of the motherboard. It’s utilized to keep CPUs with high thermal power designs from overheating, which necessitates a high cooling solution. The water blocks are then connected to a pump, which causes water to flow through them, removing hot water and reintroducing cool water.

What is the best AIO CPU Water Block?

Ans: Choosing the ideal CPU water block for our build is difficult because there are so many possibilities out there from which we must select just one. The EKWB EK series is the greatest water block we’ve examined so far, according to research findings.

Do Intel Water Blocks Works with AMD Processors?

Ans: Because AMD and Intel CPUs use different sockets, a water block intended for Intel will not function with AMD. Because they are made to function with both the LGA AMD AMx sockets, Intel water blocks only work with AMD in a very small percentage of circumstances. There are also workstation processors that use a different socket and require a water block that is compatible with that socket to function properly.
