If you're looking for the best PC cooling fluid, we've got you covered right here.

Water cooling will also cool any new components you may wish to add, such as the best DDR5 RAM if you've got a compatible system, and any of the upcoming AMD Radeon RX 7000 series GPUs.

Once you've sorted your loop out, it's then a case of looking at which coolant you'd like to put in, as there are a few different choices out there.

Interestingly, you don't actually have to use water for liquid cooling. There are specific coolants available that are dyed in different colours, which can be handy if you're wanting to go for a specific aesthetic or colour scheme within your PC build.

With all this in mind, we’ve selected these cooling fluids based on our research into their specs, features, general reviews, and other general points, that we think make them worth considering, plus, we’ve answered some of your most frequently asked questions so you can pick the best one for you.

Frequently Asked Questions

Is liquid cooling a PC worth it?

Liquid cooling could be worth it for your PC as it's traditionally more efficient and sometimes quieter than traditional air cooling, and cosmetically, also looks rather cool, especially if you pair it with the right cooling fluid.

Making your own custom water cooling loop isn't easy, but if you do know how to do it, then liquid cooling your PC can be worth it.

Is it hard to install liquid cooling?

This all depends on the time of liquid cooler you buy. Some AIO (or all-in-one coolers) keep things simple by providing everything you need all in one box, from pumps to tubing and radiators.

With these, water cooling loops shouldn't be too difficult to install, given you get everything you need, and it's a simple case of following instructions.

How often should you change the liquid in a liquid-cooled PC?

As a general rule of thumb, changing your cooling fluid every 12 months or so is advisable to ensure optimal cooling performance, and also to clean the pipes out so there are no blockages or particle build-up.

But if you choose a coolant with UV additives, and want it to keep the UV effects, you'll want to change it every 6 months. However, this is not imperative for its function as a liquid cooler.

How much should I spend on PC cooling fluid?

As a general rule, we'd say to spend between $20 and $40 to get some good cooling fluid. Going within this price bracket should get you a fluid that not only comes in multiple colours but also feature special formulas inside to keep your PC running as best it can.

Does liquid cooling require maintenance?

In all honesty, not necessarily. As a liquid cooling loop forms a sealed system it doesn't require much maintenance, if you go for an AIO setup, that is. Building your own custom loop may require some maintenance, just to keep everything in check.

You can read more about why regular coolant maintenance is important right here.

Can you mix PC coolant with water?

In short, you can, as long as the coolant supports it. Some require being mixed with water in order to function, while with others, you can pour them into your cooling loop as is, and they should work absolutely fine.
