When it comes to your PC, there are various cooling solutions that you can opt for.  The majority of people will go down the route of using an air cooler. There’s nothing wrong with doing this, quite the opposite in fact. However, a more common option these days is to water cool your PC. There are two main ways that this can be brought about. The first is to use an All in One water cooler. In this scenario, everything is self contained as the name suggests and as classed as closed loop. The other option is to use an open loop system. In that type of configuration, the end user has complete control over the tubing options, as well as the radiator and fans that are used and are what people normally think of when they hear people discuss watercooling, otherwise known as CPU liquid cooling. This is a common practice for those that want to overclock their CPU. This, for those that are unsure, is pushing their CPU above the specification on the box, i.e. 3.5GHz being increased to 4GHz.

In this article we’ll be taking a look the best all in one water coolers currently on the market. As new products become available this article will be updated accordingly to reflect the new coolers that are available. The reason for focusing solely on AIO coolers here is that it is the quickest and easiest way for anyone that wants to have a water cooling setup without having to worry about any potential leaks or damage to their system.

The biggest benefit of a liquid cooling system is that the noise coming from the PC is greatly reduced. If you’re really pushing your system to the limits, investing in an all in one configuration is a great way to have a quiet CPU cooler. Also, unlike an open loop system, you don’ need to worry about having a reservoir to contain your coolant of choice. Likewise, you won’t need to worry about any kinks in the tubing which can be a problem in an open loop system nor will you have to invest in a pump, which can be usually pretty expensive and sometimes noisy. Regardless if you have an Intel CPU or an AMD CPU, because an AIO is regarded as an aftermarket item, you can get one which will fit both processor types.

Corsair Hydro H60

For those that are tight on a budget, Corsair has you covered with their Hydro H60 cooler. An interesting fact is that thermal compound has already been pre-applied to the heatsink on this cooler. Of course, if you had to take it off for whatever reason it would be advisable to re-apply the thermal paste. You can read more of our picks of the best thermal paste over here.

At less than the cost of a recent AAA video game in a deluxe configuration, this cooler is phenomenal. In order to assist in heat dissipation, the heatsink is composed of copper which helps to transfer heat a lot better than aluminium.

One of the unique features of this liquid CPU cooler is that there is a large degree of compatibility, no matter what your motherboard is. It supports a wide array AMD and Intel CPUs including AM4 for Ryzen thanks to the included mounting brackets. It is a single fan setup, with one 120mm fan included in the box and is attached to the radiator. Of course, you’re able to swap out the fan if you so wish. Due to it being a single fan setup, it is a better option for those that have a smaller setup. An example of this would be those that are building a small form factor PC and are using a mini ITX case, although it’s perfect for use in large PC cases too. This is a great option for those that want a quieter PC whilst at the same time not having to worry about messing around with cooling liquid and don’t want to struggle with CPU throttling. This can sometimes be an issue in a mini ITX case  due to a an overall lack of CPU cooling. Therefore in an enclosed environment such as this, PC liquid cooling can really help prolong the lifespan of your device.

  • Performance liquid CPU cooler
  • Improved SP120L fan offers lower noise and high performance
  • Pre-filled, never needs refilling

Corsair Hydro H100i v2

If you have a full sized case, a great all in one cooler is the Corsair Hydro H100i v2. This has been classed as (at the time of writing), the best selling all in one cooler in the world. The radiator is double the size of the H60, with it being 240mm. It has two, 120mm fans pre-installed onto it. There are PWM fans that excel in conducting heat and therefore lowering the overall temperature of the CPU.  The benefit of the PWM (pulse width modulation) is that via the companion software, you are able to configure the fans so that they will spin at your desired speed. The benefit of this is that you can run a more efficient set up by allowing the fans to be tweaked depending on the task that the CPU is doing.

Similarly, thanks to the Corsair Link software you are able to adjust the lighting of the cooler. This liquid cooler is RGB enabled, with RGB being a common option in a gaming PC. Out of the box, the default colour is white. However, you have a wide range of colours that you can choose from. If you have a case that has a side window and RGB is your thing, this is a great option to really make your rig look amazing.  As is the case with the H60, the heatsink is made from copper to allow the maximum level of heat conductivity.

Thermaltake  Water 3.0 Triple Riing

For those that want to go to the extreme when it comes to CPU cooling, it’s now possible to get a triple fan setup. As you’d imagine, this is an excellent way to get some hardcore PC cooling and therefore severely reduce the chance of your build overheating if you’re into overclocking. Basically if you’re an overclocker, this is the cooler for you! In a study by Thermaltake, when using their Triple Riing RGB cooler on an Intel Core i7 clocked at 4GHz, the maximum temperature was 72°C. This was under a load of 100%. When using the same CPU but this time with a stock Intel cooler, the maximum temperature was 94°C under 100% load. This really is a phenomonel drop in temperature when using this water cooling kit. For other users over on Amazon, they have noted similarly impressive reductions in temperature. One user used to have temperatures  toping out at 70°C. After installing this their temperatures maxed out at 37°C which is amazing.

It is compatible with a wide array of sockets from both Intel and AMD. However if you have an AM4 processor (such as Ryzen), then you will need to purchase this mounting bracket separately. As with the two Corsair coolers above, the Thermaltake Riing has a copper water block to keep the temperatures low. For added peace of mind, there is an included three year warranty.  When it comes to this you’ll have no problem using a CPU that has been overclocked and you’ll be able to get extreme performance out of your build. Handily, it connects to your motherboard via it’s 4 pin connector, as does the other coolers listed above. It is also RGB enabled, so you can customise it until your hearts content and get it to match with the other RGB components in your rig.
