You may be asking yourself the question; what can I do to avoid over-heating my PC? The answer is simple and straightforward; get the right pc coolant. PC coolants come in different forms and components, you should consider the one that is most suitable, safe and convenient. Some come as premixed and others will require mixing some distilled water with them.

The Best Rated PC Coolant

Why Does A Coolant Matter?

In modern PC processors, more and more transistors are being installed to increase the performances of the devices. Aside from performance enhancement, the speed of PCs is also being enhanced with an increase in the number of transistors.

Due to the electronic tension created by this upgrade of transistors, the surface of the processor will become heated. The overheating of your PC processor can lead to several problems where several components may become damaged.

Since many transistors are installed very close to each other within the PC, the rate of heat generation is further increased. In addition to damages, a decrease in the performance of your PC will occur when temperatures rise to 60°C. In the worst scenario, hardware failure may occur.

To avoid overheating, hardware failure and a decrease in PC performance, a PC must be supported by a cooling system. A cooling system will quickly remove heat from the processor core as soon as it is generated. Though enlarging the heat output surface of the PC is another way of eliminating heat, it is still not as effective as using a coolant.

How To Choose The Best PC Coolant

Choosing a PC coolant can become a daunting task in the beginning but until you get the right one. The main factors you may want to consider when choosing the right coolant are;

  • Type of coolant
  • Pre-mix or not
  • Lifespan.
  • Compatibility with different materials
  • Electrical and Thermal conductivity
  • Biodegradability
  • Ability to Retain Color in Loop
  • Sensitivity to Temperature and other external factors.

1. Cost and Budget

Cost or budget should be your last consideration when it comes to choosing a coolant for your PC. Many things determine the costs of a PC coolant. Non-mixed products cost more because they have not been mixed and are highly concentrated. This does not mean that premix is of inferior quality to the other option, it simply saves you time on mixing with water.

Make sure you consider the quality of the product first before you settle for one. PC coolants are widely affordable, you should be able to find the ideal product within your budget range. It is equally important to avoid imitation products that are ridiculously affordable.

2. Pre-mix or not

There are basically two types of coolants, these are the premix and the ones you need to mix with a portion of water. Perhaps for convenience sake, you may want to consider whether the PC coolant has been premixed or not.

If the coolant is not pre-mixed, you will have to follow directions on the container. In most cases, coolants that are not pre-mixed will be required to be mixed with distilled water at a quantity.

For instance, most unmixed coolants will require that you mix the content at ratio 1:9 of coolant and water respectively. The premixed coolants are much better and preferred because they save time. In most cases, non-premixed coolants are more concentrated than pre-mixed options.

Non-premixed coolants are also more expensive than pre-mixed. If you don’t mind the extra time you have to spend mixing, the non-premixed may be a better choice since you have control over how much you use at a time. Make sure you follow the direction of the application when mixing the non-mixed product.

3. The lifespan of the Coolant

The lifespan of coolant also matters when it comes to choosing your final product. Most coolants will last for 2 years or less in most cases, but that depends on the way you handle the product. There are some products that may last for more than 2 years when properly preserved. If for instance, you constantly leave the coolant opened consistently, it will lose its color and potency. Some coolants do develop sediments when they start losing their potency and power. For this reason, the lifespan of a coolant generally depends on the way you store and handle the product.

4. Compatibility with different materials

Since the PC has diverse components made of different materials, it is ideal that your choice should be compatible with them. The ideal coolant should not corrode or cause damage to solid components like brass, copper, gold, stainless steel, aluminum, neither should it be corrosive against acrylic, POM Acetal, PETG, and Rubber. Items that coolant is not compatible with must be clearly listed on the package as a warning.

5. Electrical and Thermal conductivity

Electrical and thermal conductivities can be used to screen your final PC coolants. For safety reasons, a coolant must have a very low electrical conductivity rating. For a coolant to be effective, it must have the highest thermal conductivity rating.

The thermal conductivity rating of the coolant is its ability to dissipate heat quickly away from your PC. The lower electrical conductance means there is a very low risk of electrical shock when applying the coolant on your PC

The higher the thermal conductivity rating, the more efficient the coolant. Similarly, the lower the electricity rating, the safer the product. Do not compromise safety and efficiencies for price. You will likely find higher thermal rated coolants costlier than lower-rated products.

6. Biodegradability

This may not be a very critical factor for you when choosing your ideal PC coolant but it is critical to the environment. Fortunately, all the products reviewed in this content are made up of biodegradable components which make them completely safe for the environment. Though these coolants are biodegradable, this does not mean you should ignore proper disposal. Disposal guidelines are usually written clearly on the outer later of the container, and they must be strictly followed. Most of the products listed in this review will degrade easily within 30-45 days of disposal, hence they can be recycled for as long as they remain useful.

7. Ability to Retain Color in Loop

PC coolants come in different colors whether they are pre-mixed or not. Some of these coolants may change colors due to their components or when they react to certain substances they come in contact with. A coolant that changes color after application should be avoided, it simply means it is unfit for the PC. An ideal coolant should not only retain its color after application, but it must also do so even in storage. Some coolants can be reused up to three times without them changing colors. You need to find out the type of coolant you choose before spending your money on any.

8. Components

Added components matter when it comes to shopping for your coolant. Coolants are supposed to contain biological indicators and anti-corrosive materials. They are not supposed to contain chemical substances that are toxic to the PC and any parts.

Fillers, including bittering agents, preservatives and colorants must also be avoided in coolants. You must pay attention to the label when choosing your ideal product. Some product manufacturers may hide the fillers from the label though the put such to increase the content volume.

9. Sensitivity to Temperature and other External Factors

Unfortunately, most PC coolants have their temperature ranges. The lower the temperatures below a certain point the lesser they perform. As a precaution, you should go for a coolant that has a temperature cap of up to 60 ℃ and can still withstand lesser than -10 ℃.

At certain temperatures, some coolants may not work at all or may simply freeze off. You need to be aware of the temperature sensitivity of a coolant to avoid application in days that don’t favor such temperature sensitivity.

You should also check whether the coolant is for individual household or industrial use. Though, some coolants are rated for both household and industrial use, you must check the temperature sensitivity of the product before choosing. Generally industrial grade coolants have wider temperature range sensitivity than household coolants.


Now that you have solid information on how to choose the best PC coolant, you should be able to make an informed decision. Your final decision should be based on the factors explained here. Since this review and guide has also included some of the best options out there, you should also consider choosing one based on your preferences.

If you are unsure about the best options for you perhaps you should go for two or more products at a time. While the budget plays an important role here, it should be your final consideration. You don’t want to compromise on quality for affordability, hence the costs of products should be the last factor.

You should also be careful where you purchase your product from. While reputable links have been provided in this content, you should avoid imitations. Imitation products don’t get covered by the manufacturer warranty; hence, you wouldn’t get a replacement or refund.
