A Beginners Guide to AIO Water Coolers

A Brief History of Water Cooling

As gamers and PC enthusiasts work to extract every single drop of raw power out of their processors, video cards, and memory, they push their computer’s internal temperatures to a higher level. Water cooling kits were developed to arrest this thermal arms race. Water cooling uses a coolant-filled loop to draw heat away from vital components and then carries that excess heat to a radiator – much in the same way a car’s cooling system works. This prevents damage to vital components and allows the user to push their gaming rigs or personal computers to all new speeds.

In the past, users who wanted to try out water cooling had to assemble all of the parts they needed and then assemble them in a safe manner to water cool their rigs. Some of the parts that they would have to get included a reservoir, pump, water blocks, tubing, an assortment of fittings and/or adapters and finally, the coolant. And many of these products weren’t even designed to go into a computer. They were salvaged from other applications. While some individuals were able to cobble together great cooling systems this way, a lot of people ended up destroying their computers when their cooling systems leaked or unexpectedly failed.

In response to the growing demand for water coolers, companies began to release “kits” which had all of the components a person needed to water cool their system. Unfortunately, a lot of these kits were difficult for first-time water cooling enthusiasts to use, so people began to look for a better solution.

The next thing that happened is that AIO water coolers entered the scene. These coolers simplified the whole process of water cooling. In fact, they are only made using a few key components. Usually, these systems use a water-block, a fluid reservoir, a pump and a combination unit. Heat is absorbed from the CPU through a copper block, and then water is pushed over this copper block to transfer the heat from it to the water. The water then travels through tubes and to a radiator. A fan blows air over these fins, transferring the heat from the radiator to the air where it’s blown out of the case. This cycle goes on, again and again, a process which keeps the CPU cool.

Why are AIO Water Coolers a Better Cooling Solution?

While all water coolers do a better job at cooling a PC than just fans alone, AIO water coolers are the best water coolers because they’re easier to set up. These systems really take all of the guesswork out of water cooling. They have few components, so they’re easier to setup and users don’t have to add coolant to them because they already have coolant. And many of them even have copper blocks that are shipped with thermal paste already on them. As you can see, this really makes installation a snap.

How to Choose an AIO Water Cooler

Choose the Right Type

There are some AIO water cooling systems that work with AMD processors and some that work with Intel processors. Be sure to get the right one for your processors. Some cooling systems can be used with both systems, using an adapter that either comes with the system or is purchased separately.

Radiator Fan Size

The most important thing that a person should consider when choosing an AIO water cooler is radiator size. The first thing that needs to be considered when deciding on radiator size is whether you have the appropriate size fan slot. You don’t want to go out and buy a 240mm radiator when you’re fan slot is the only 140mm, so always be sure that you have the appropriately sized radiators. However, there are some coolers which can help bridge the gulf between 120mm radiator fans and 140mm radiator fans by making the radiator itself thicker. For example, Corsair H80i Hydro Series radiators are thicker, which helps to cool down the coolant faster. Other models, such as the Arctic Liquid Freezer, use two fans to cool down. Models that have 240mm fans are often placed in the case’s top exhaust fan slot since more and more cases are shipping with this option.

Generally speaking, 240mm and 280mm options are usually the best. However, it should be noted that these models are also harder to install and usually cost more than 120mm or 140mm options. There are some 120mm radiator models that use 3 or 4 fans to cool down the radiator, and this can result in increased performance. Some of the newer radiators have a 320mm size and use up to 6-fans to cool them.


It’s also a good idea to thoroughly read the description of whatever closed-loop water coolers you’re thinking about buying. Not all of them have the same selection of accessories. Make sure that the unit you want to buy has all of the necessary hardware to install it and a processor adapter if it needs one. Also, check to see if it comes with thermal paste. Some units already have thermal paste on the water blocks, so they’re pretty much ready to go when you get them. If your particular closed-loop water cooler doesn’t come with thermal paste, then be sure to order some because you’re going to need it.

Assemble Your Tools

You’re going to want to have some tools available to install your water cooler. Here are some of the more commonly needed tools for this operation:

  • Anti-static wrist strap
  • Philips head screwdriver
  • Microfiber cloth
  • Thermal paste

The Last Word

Cooling you PC or gaming rig with a closed-loop cooler doesn’t have to be difficult or time-consuming. Just be sure that you have all the tools you need to do the job assembled and that you do your research when choosing an all-in-one water cooler. Once you receive the cooler, be sure that you read all of the instructions that came with the unit and follow all safety precautions. If you do that, then you should end up getting many hardware generations of life out of your cooler.
