Top 7 Best Water Cooling Coolant
A good coolant is necessary to keep the optimum temperature maintained in the system. The coolant should be germ-free and visually attractive too to illustrate the flow.
Some coolants can cause silting damaging the entire cooling system. And so, the finest quality coolant is needed.

So, here are the leading PC water cooling coolant available for your gaming rig:
1. PrimoChill VUE
Primochill vue stands above all for showcasing the coolant in the watercooling loop with its cool ocular traits which is useful to illustrate fluid flow patterns.
Vue’s unique water-based formulation allows the fluid to stay suspended for a long time providing longevity.

One more interesting fact about VUE is:
This coolant includes non-toxic corrosive inhibitors and a natural antimicrobial growth fighter and is 100% safe to use with all rubber gaskets, acrylic tubing, pvc tubing, petg tubing, glass tubing, as well as nickel and copper components.
Special features of PrimoChill VUE are:
- 25 different available colors
- 32 oz cooling fluid
This coolant is bio-degradable, pre-dyed, and handmade but shows low conductivity.
Though this coolant has amazing visual traits, one downside of using VUE is that, it causes silting in radiator and water blocks. For which, your gaming PC will run slower than usual.
Overall, VUE has a high attraction to dyes and is mended for experienced users.

4. EKWB EK-CryoFuel Solid Concentrate Coolant
This product model is similar to the premix one. The only difference is that, this cooling fluid is concentrated and lesser in amount for PC watercooling application.
This water cooling fluid is available in 7 colors with 250 mL liquid. It needs 750mL of distilled water to make it complete.
Like the premix model, this coolant is also low electrically conductive. It also has biologically growth inhibitors and also corrosion protectors.

The only problem with this coolant is that:
If you use it for more than 3 months, you will see that the liquid is cluttering your loop showing sediments.
This sedimentation is caused if you use this cooling liquid as it is and don’t mix it with water.
Besides, the colors also fades away because of long term usage.
One more thing I don’t like about this fluid is, it falls short when you have a high capacity reservoir, radiator, tubing etc.
If I have to compare the color and consistency of this fluid, it would definitely be milk.

WaterCooling Liquid Buyer’s Guide
There are some aspects you should consider before buying the liquid for your gaming rig.
A coolant is 99% needed component to optimize the temperature of the system.
As a gaming enthusiast, I myself studied several fluids. Some damaged the entire rig and as some faded their color. While the best ones i still have are most demanding in the market.
So, here are the aspects you need to consider before buying a cooling fluid:
Available Color
Watercooling fluids come in different available colors. So, choose the color of the fluid before buying one.
I personally like the aqua color in a soft tubing system more than anything. However, you can choose any of them according to your taste.
Type of Solution- Concentrated or Premix?
Cooling liquids come in two forms, concentrated and premix. In premix form, Distilled water is already added to the solution and so, you don’t need to add any extra.
Whereas, in concentrated forms you have to accurately measure the distilled water amount and then mix it with the solution.
I prefer using the premix one, because in some countries distilled water is overpriced and hard to find.

Amount of Fluid
It depends on your cooling loop, how much amount you need to pour in the system. Cooling fluids come in different quantities. If you have any spare liquid, it will be of a complete wastage.
And most cases, you don’t want to notice short quantity of liquid. Do you?
So, it is essential to ask the amount of fluid before buying one

FAQ
Question: Does distill water need to be added in water cooling liquids?
Answer: If it is a concentrated solution, then distill water is to be added. And, if the solution of the cooled liquid is premixed then, distill water is already added to the solution.
Question: What happens if water cooling fluid leaks through the tubes?
Answer: Your entire watercooling build will be damaged as the fluid itself is a chemical and it can corrode other components of your PC.
Final Thoughts
The best water cooling coolant are those which are naturally biodegradable, has anti-corroding and anti-bacterial agents in the solution.
Nevertheless, it should be appealing too and also it should be consistent enough to provide pump a helping hand in the flow.
Overall, Mayhem’s Pastel is the finest of all and considered to be the most demanding one.
Do mention in the comments if you think any other cooling fluid is effective enough for the build.
