What is an AIO Water Cooler?

AIO means all-in-one. Whether it is liquid cooling or air, these things require many components and can be difficult to install. These involve reservoir, pump, CPU/ GPU/ Memory block, and fans, to name a few. The All In One Option gives everything you will need to use packaged into one compact container. This makes it a popular option with beginners and people who don’t want to spend hours setting up their cooling systems.

Water cooling is one of the most common forms of liquid cooling in the CPU and is becoming more popular than air cooling its self. This is because of the high thermal conductivity of water compared to other options. Some of the many benefits of water cooling involve large and cheap availability of water and its non-toxic characteristics.     

How Does an AIO Water Cooler Work?

Water cooling uses the principles of thermodynamics i.e., heat moves from warm to cool surface. This transfer of heat results in the warm surface getting cooled down, and the cool surface getting warmed up.

This same concept is applied to many things, including cars. The heat of the microprocessors is transferred to the water to be expelled. Water serves as a medium of heat transfer, and this is where its high thermal conductivity and specific heat capacity comes in play.

There are four main parts of the water cooler, including a pump, radiator, fan, and coolant reservoir. The pump moves the water in and out, the radiator expels the heat outside, the fan helps the radiator to expel heat, and the reservoir (as the name suggests) keeps a reservoir of water.    

Now to get the water to these heated surfaces without causing spills, you use blocks. Different blocks are made for CPUs, GPUs, and memory as well. The GPU block is the most common one because it does intensive graphics processing. These blocks are made of conductive metal surfaces and are placed directly on top of the heated chip. The water flows from the reservoir through these blocks and pumps in the system and directs heat away from them.

After the water gets warm, the radiator and fan remove the heat from the cooling system, and the re-cooled water starts its journey again.

What to Look For When Buying an AIO Water Cooler

While water coolers have many advantages over conventional air cooling, there are some things you should remain cautious about.

Noise

Liquid coolers are louder than air coolers because of the fan and pumping of water through the system. For the most part, the noise should not bother you that much, but every system is not built the same. Our top picks generally don’t have a noise problem and promise a quieter experience.  

Efficiency

The most important part of any cooling system is its efficiency. If it cannot remove enough heat from the CPU in time, then what is the point of it all? Water coolers are used where air cooling fails, and that is when you overclock. Overclocking can cause your system to heat up a lot, especially if it is old.

You should also make sure that your cooler is reliable and will not leak. Liquids and electronics never mix well. The cooler should have a durable pump and features to help avoid any leaks. 

Aesthetics  

Generally, when you custom-build your CPU, a lot of the focus goes into its look. Water coolers have the option of RGB lighting as well to suit your overall look. After checking the most important things like performance and compatibility with your CPU, you can look for these extra things.

Pros and Cons of AIO Water Coolers

Water coolers have many advantages over conventional heating, but when it comes to using them with electronics. There are some cautious tales, as well. Here are the pros and cons of using an AIO water cooler.

Pros

The following are the benefits of using such a cooler:

Better Than Air Coolers 

The major advantage of using water cooling is the high heat conductivity of water as compared to air. These types of coolers are much more efficient and hence used by gamers or anyone who has done overclocking on their system. These cases usually result in the failed performance of air coolers.

Installation is Easier 

Water cooling requires extra components like the pump. It makes the installation more difficult and time taking. The All-In-One water coolers get rid of that problem by combining everything in one small package. So by using an AIO water cooler, you get rid of the hassle of buying separate parts and having to search through YouTube to figure out the right way to install on your CPU.

Adds to the Aesthetics 

As you must have seen with our top picks, virtually every water cooler comes with RGB lighting. Everyone has different settings and control options, but it’s always there. Since water coolers are used mainly by gamers, it makes sense that it has this feature. Gamers often have their CPUs customized with different components using RGB lights. The addition of a water pump with similar aesthetics is a plus.       

Cons

At the same time, you might come across these disadvantages:

Chances of Leaks 

Water and electronics together sound like a recipe for disaster, and that is what can happen with many low-quality products. There have been many reported pump leaks that destroy your system. But if you use a high-quality water cooler with anti-leak features, this can be prevented widely.

Comparatively Expensive 

Water coolers have more parts and hence are more expensive than air coolers. For many people that don’t do overclocking, buying an expensive water cooler seems unreasonable. For them, the change in performance will not be too big.

How to Install an AIO Water Cooler

For installation of AIO water coolers follow the steps below.

  1. Things you will need are radiator, pump, fan, screws, and backplate.

  2. Remove the front and back panel of your CPU case.

  3. Put the fan on top of the radiator.

  4. Use the long fan screws to secure it in place.

  5. For airflow direction indication, check on the side of your fan.

  6. Secure the fastener to the base of your water block.

  7. Put the bracket on the back of the motherboard and secure using support screws.

  8. Apply thermal paste to the CPU if not already pre-applied to the water block.

  9. Mount the fan to your chosen location, secure it with screws.

  10. Align the fastener of the water block with the support screws.

  11. Use thumbscrews to secure it in place.
