Custom Water Cooling: The Best Coolant

We have been spending some time talking about custom water-cooling and the good thing is that it certainly is one of the best things that you can do. Why? Because you can actually get a lot of performance out of your PC and not just that, aside from the performance factor, you have the ability to make your PC look good, and one of a kind.

However, the one thing that we often overlook in custom water-cooling is the number of different components that we have to choose in order to make everything work. Do remember that all these components work in tandem, so even if a single component is not supported, or out of place, you are not going to have the optimal results.

In this article, we are stressing solely on the coolants and helping you find the best coolant for your PC. The good news is that there is not a lot of saturation in the market. Sure, there are a number of different brands, but they are all working in the same capacity with very little to differentiate them. The good news, here is that you can actually create your own coolant as well, which we will get to in a short moment.

Let’s have a look at what we are talking about.

Distilled Water is Your Friend

Imagine spending upwards of $700 of water cooling components only to use distilled water as a coolant. Sounds odd, right? Well, the thing is that this type of coolant is definitely great because it is great at cooling components. You can buy a bottle of distilled water from your nearest supermarket and use that in your reservoir. The whole goal is to make things easier for you and you can do that with ease.

Now the crux of the situation here is that when it comes to distilled water, you have to make sure that it is prepared to be used as a coolant. Obviously, it is going to stay inside the blocks for some time, which means that there is a chance of algae growing, and chances of corrosion as well. The best way to is to add biocide in the water. Biocides are transparent, so if you are going for a completely transparent loop, these are great and will not let any corrosion or algae happening in the loop.

When you combine distilled water with biocide, you are good for at least 6 months or a year. With that said, if the look of clear water is something that is boring you, you should definitely try going for some dyes to add color to the build. Trust me; it makes everything look a lot better and with more character.

Premade Solutions

If the whole idea of buying distilled water with the right biocide and adding dye is something that bores you, then another good news is that you can go with premade solutions. Yes, that is right; several enthusiast companies like PrimoChill, Mayhem, and a few others are making coolants for your CPUs in order to help you make the most of your experience.

The best thing about these coolants is that they are prepared out of the box, so you just have to put them in your loop and you are good to go. One of the best thing about going with such vendors is that with these, you will get a whole lot of options. For starters, the Mayhem Pastel lineup is amazing with vibrant, pastel colors that look good. You can even go for some really wicked looking combinations, and some of them are even UV reactive.

When using these premade solutions, you just have to make sure that the loop is properly flushed, and that is about it. However, some of these coolants might not play well with the parts you are using as they can actually cause distortion or blockage in the pipes.

To tackle that issue, the right thing to do would be to do your research and go with the one that has the best reviews according to your requirements.


In conclusion, when it comes to coolants. Whether you are using distilled water, or you are using a premade option, there is nothing wrong with it. Just make sure that you are well aware of the prerequisites because they happen to be extremely important and should not be missed at all. Once that is done, you will be good to go. Lastly, if by any chance you are rocking a Ryzen 1700x and you don’t want to go for the custom water loop router, you might be better off buying these coolers instead of a whole custom water cooling setup, so definitely check them out while you’re at it.
