Top 5 Best CPU Water Block for Maximum Overclocking

A CPU water-block is a needed component in a cooling system that draws the additional heat from the CPU for fast-performance and maximum overclocking.

As a gaming enthusiast, I found a few mono-blocks that are worth spending the money. And, in this post, I am going to review them on the basis of aesthetics,

So, here are the 5 CPU blocks reviewed:

1. Bitspower CPU Waterblock Summit EF Lite

Normally, Bitspower stays with the color black and white but, this time they decided to go for multicolors. This CPU block is available in three different colors.

The dimension for this product is 95 x 95 x 18 mm. This blocks top cover is made of hi-quality clear color acrylic and the base is made of hi-quality copper. Mounting Bracket is also black.


This is the lite version but, there is also an RGB version to it. The difference between armor edition and armor edition lite is that the lite version has a space on the side to insert an LED.

Bitspower CPU Block Compatibility: Intel LGA 775, Intel LGA 1155/1156, intel LGA 1366, Intel LGA 2011, AMD Socket 939, 754, 940, and AMD Socket AM2, AM2+, AM3, AM3+, FM1.

2. EKWB EK-Velocity Strike

A CPU block like the EK-velocity strike is what handles the heat transfer efficiently between CPU and water-cooling loop. For modern Intel and AMD processors, this flagship premium quality block is the best.

The 45-degree angle line design across the center matches perfectly with the new generations high-end motherboards.


The Ek-velocity strike block has low hydraulic flow restriction which allows it to be used with weaker water pumps for silent operation. Trust me. This product shows top-performance for overclocking.

The thicker integrated jet plate allows more precise bow control. Its simplified structure adds optimal coolant flow and easier maintenance.

The block is enhanced with enclosed mounting kits and brackets. The Ek-velocity features a universal mounting mechanism that offers error-prevention, tool-less installation supporting Intel LGA-115x and LGA 20xx sockets. This model also has an RGB illuminated Ek logo which is compatible with all RGB sync technologies.

Ek-velocity CPU socket compatibility:

  • Intel LGA-1150/1151/1155/1156
  • Intel LGA-2011(-3)
  • Intel LGA-2066
  • AMD AMD4

Overall, I prefer using the Ek-velocity because of its outstanding specs. Also, keep in mind that, this product is not to be installed with any Aluminum Ek-fluid gaming parts.

3. Corsair Hydro X Series XC9

The Corsair Hydro X Series XC9 is a combination of premium construction, bright RGB lighting, and outstanding cooling performance.

This waterblock has 70 highly efficient micro-cooling fins that draws the maximum quantity of heat from the CPU taking the overclocking speed to maximum limit. It has 16 ARGB LED’s that delivers outstanding customizable lighting effects when combined with Corsair lighting Node PRO or Commander PRO.


If you want to show off your coolant to all its glory then, The Corsair Hydro X Series XC9 will be the best choice for you.

In other words:

This block is built better with premium sandblasted aluminum trim and intelligent lighting control.

Corsair Hydro X Series XC9 has socket compatibility on:

  • Intel LGA 2066 or AMD Str4 sockets only.

Though this monoblock is easy to install, its low socket compatibility option shows one downside effect.

Otherwise, it is an uncompromising CPU cooler with clear Integrated RGB lightings.

From my point of view, this water block looks great with the LED face. It gives smooth water flow through block without leaving any water bubbles and also easily installable.

4. Thermaltake Pacific W4 Plus

Thermaltake Pacific W4 Plus monoblock combines the gorgeous LED light with edge-cutting technology for a brand new experience of using PC cooling system.

The Pacific W4 plus RGB LED’s can be controlled very easily with parented Riing Plus RGB software. For error free installation, it features 0.15mm internal fin construction, a copper base with anti-corrosive nickel plating and high-quality PMMA cover, and a universal mounting mechanism.


Thermaltake Pacific W4 Plus is socket compatible with:

  • Intel LGA 2066/2011 3/2011/1366/1156/1155/1151/1150/775
  • AMD FM2/FM1/AM3+/AM3/AM2+/AM2/AM4 sockets

It fits most G1/4” fittings and provides the ultimate cooling performance with extreme compatibility for custom PC builders.

Some of the unique features of Thermaltake Pacific W4 Plus are:

  1. Their Heatsink material is made up of Copper + PMMA
  2. Rated Voltage is 5V
  3. Connector: 4-Pin Molex

In short:

It is one of the leading water block from Thermaltake brand.

5. Phanteks Glacier C350I

Phanteks Glacier C350I is an amazing block because of its larger copper base (70 X 70 X 4 mm). You can’t find any larger copper based CPU Block in the market.

The fine-tuned 0.15 mm internal fin construction makes C350I perform excellently. It also has an acrylic top with aluminium side covers.

Want to know the best part?

For improving thermal conductance between components PHANTEKS includes Phantek’s PH_NDC with military-grade Viton O-rings. The Viton rubber washers help resist damage during installation and use.


CPU Socket compatibility of Phanteks Glacier 350I is:

  • Intel LGA 115x, LGA 1366, LGA 2011(-3), LGA 2066 (AMD sockets require a different block).

It can bear increment of temperature and also stands up tall to aggressive coolants.

It uses the same RGB connectors as the Phanteks cases. Moreover, the Glacier C350I can synchronize with the case featuring a connection terminal as well which reduces the flow resistance.

Overall, Because of its extreme cooling performance and optimal heat dissipation, Phanteks Glacier stands above all.

How to Buy The Best Water Block: Beginners Guide

Monoblock is mandatory for cooling loop when it comes to cooling down your CPU during advanced gaming.

A good quality water block is needed in this case. There are some basic things you need to know while buying a good water block,

So, here are the conditions you need to consider before buying any water block:

Socket Compatibility

Socket Compatibility is one of the key factors to be considered before buying a water block. You have to find out the socket type of your CPU and match it with the water block socket.

You don't want to waste your entire money on a water block that is not even compatible with your CPU sockets. 

For easy installation of the monoblock, socket compatibility should be the first considerable feature.

Quality of the Block

The quality of the block should be spectacular. The design of the base plate is very eye catching and so, you have to choose the most durable water block for your water cooled gaming rig.

If the waterblock is not durable then, it would be very difficult for you to keep the block safe from any hazards for a long time.

Mounting Hardware

Some waterblocks don't come with mounting hardware which makes it tremendously difficult to install the block. 

I have mentioned only those products which provides necessary mounting hardware for helping you to easily install the CPU block.

So, you don't need to look for the necessary equipment again and again.


Question: Why a water block is needed for cooling?

Answer: Water blocks transfer heat from PC components towards the coolant and so the optimal temperature is maintained.

Question: Do I need to Watercool my CPU?

Answer: For cooling down the environment of your CPU, it is mandatory to use coolers. If you want to build a watercooled PC then, you must use a waterblock in order to watercool your CPU.

Final Thoughts

Every single cash counts while buying the best cpu water block for your gaming rig. The block must meet your aesthetics and also perform excellently without any faults.

CPU water blocks are essential when it comes to cooling down the temperature of the CPU. Basically, On an average scale of 10, chances the waterblock getting damaged is 8 due to low durable products.

So, it is essential to build a water cooled PC with a highly performance product. 

I would recommend to go for Ek-velocity or Corsair waterblocks mostly because of their availability and advanced level performance.
