Bitspower CPU Block Summit Revo Intel Edition(12th/13th/14th Gen Intel CPU,LGA1700)

Bitspower presents a revolutionary CPU water block - the Summit Revo, a cutting-edge water block that combines new concepts with innovative design. Not only does its appearance evoke a refreshing feeling, but its thermal performance also excels in meeting the challenges posed by new-generation CPUs.

Upon inspecting the exterior of the Bitspower CPU Block Summit Revo, one can readily observe the absence of outlet holes on its main body. This is a carefully crafted design that utilizes the structure of the motherboard to guide the water flow to the backside of the motherboard, where multiple outlet holes are strategically placed for user convenience. This innovative design ensures that the top surface of the water block remains free of any protruding structures. If you appreciate a clean visual aesthetic, this cooling solution will be your top choice. Alternatively, if you enjoy personalization in design, this water block provides greater creative freedom.

The unique external design does not compromise the performance of this water block. Adhering to consistent design principles, it features a copper base plate, high-density heat sink fins, and a water injection design, all contributing to providing the best cooling solution for new-generation CPUs. Whether you seek a revolutionary CPU water block excelling in aesthetics and performance, the Bitspower CPU Block Summit Revo is an absolute must-have.

Water Blocks


Alphacool Eisblock XPX Aurora CPU Water Block - Plexi Black Digital RGB

Level up your gaming PC’s cooling performance, by equipping it with Water Blocks from Barrow, Phanteks, Thermal Grizzly, Corsair, EK Water Blocks, and more. A water block is a vital component in a custom loop, designed to facilitate efficient heat transfer between key hardware and your coolant. Typically, a water block consists of a copper cold plate, inner housing that has coolant channels, inlet and outlet ports, and a protective casing. Many water blocks feature a micro-fin array milled directly into the cold plate to maximise its surface area, ensuring efficient heat dissipation can occur. Water blocks are available in a range of styles and finishes to pair with your favourite hardware and match your unique aesthetic.


Types of Water Blocks

Water blocks come in all manners of shapes and sizes, designed to be paired with a wide variety of hardware. Some of the most common types are:

  • CPU Blocks: These water blocks are designed to maintain your CPU at optimum temperatures. Most models will mount on top of your processor’s IHS, offering a highly efficient cooling method. Easy to install, these use the same mounting hardware found with AIO and air coolers. Alternatively, there are CPU blocks that can be mounted directly to the die of your processor, delivering the ultimate cooling performance but requiring more experience.
  • Monoblock: In addition to cooling your processor, a Monoblock makes contact with components around the CPU socket. As such, these blocks are much larger than a standard CPU block but will typically utilise the same mounting hardware. This type of cooling is generally used by overclocking enthusiasts, as it allows for more power delivery to the CPU.
  • GPU Block: A GPU block will replace the existing cooling hardware your graphics card has, requiring you to make modifications. A GPU block will typically cool both the graphical processor and the surrounding components, such as VRAM and power delivery.
  • M.2 SSD Blocks: The latest generations of M.2 SSDs are capable of reaching lightning-fast data transfer rates, which comes at the cost of higher temperatures. As such, M.2 water blocks are designed to effectively dissipate this waste heat, allowing your storage drives to operate at maximum performance for longer.

Water Block FAQ


What brands of water blocks does Overclockers UK stock?

Here at Overclockers UK, you can find water blocks from manufacturers such as EK Water Blocks, Phanteks, Barrow, Corsair, and more.

What hardware is my water block compatible with?

The most common water blocks available are CPU and GPU blocks, designed specifically to cool these components. Water blocks feature unique form factors designed to deliver optimum cooling performance for specific hardware models.

Do water blocks come with mounting hardware?

Many water blocks include the mounting hardware you need to install them, such as screws, tools, and even thermal paste. Extra hardware may be required if you are building a custom loop.

Do I need a water block for my gaming PC?

A water block is a key component in a water-cooling loop. This makes them the perfect choice for high-performance computers equipped with top-tier hardware. However, if your PC features less powerful components, you can achieve excellent results with an AIO or air cooler.

How often should I clean my water block?

We recommend regularly inspecting your water block and custom loop for corrosion and bacterial build up. You should aim to perform maintenance, such as flushing and replacing your coolant, every six to twelve months to ensure your loop is performing optimally.
