Buying Guide: How to Choose a Thermal Paste

best thermal pastes

Many people aren’t aware of the importance of keeping their systems cool. Lowering down the temperature of your computer architecture helps in boosting its efficiency that eventually increases the processor’s lifespan. 

There are multiple ways to help chill your system and one of such is a small but potent method, applying a thermal paste to components that are meant to be cooled while you spend your computing hours comfortably. 

Buying this heat-conductive paste is not as simple as it seems. One has to consider more than a few key factors before choosing the best thermal paste in 2021.  

For assistance, we have briefly discussed a few essential aspects that you need to consider before choosing the best-fitting product from the top 15 thermal pastes in 2021 listed above. 

Density 

As you might already be aware that density is related to how thick or thin a substance is. You might be wondering why the thickness of a thermal paste is crucial while choosing the best one.

Well, it is indeed important. The thicker the thermal compound will be the better it will work. Not just that, but a denser compound is also much easier to control which eventually helps you in making the application process simpler. 

However, if you are a beginner, then it’s way better to go with 2-gram less dense, more viscous content so that you can easily spread it on the targeted area with the help of a spatula or spreader.

Professional users on the other hand would like to test their systems to extremes. Hence, we recommend going with a dense composition.

Storage Time

Many people believe in stocking basic items at home beforehand so they don’t have to rush to get those in times of need.

If you are also one of such people, you must check the storage life of the thermal paste that you intend to buy.

It is highly recommended to purchase a paste that possesses at least two years of shelf life.

Also, make sure that the cooling compound that you apply to your computer hasn’t dried out.

A dehydrated thermal paste loses all of its cooling characteristics and thus is proscribed to use as it can severely damage a component. 

Type of Composition

Checking the type of composition of any thermal paste that you are looking forward to purchasing and assuming its outcomes is also very crucial.

Usually, there are two main types of thermal pastes/compounds. One is conductive while the other is not. 

The conductive ones are always metallic-based and should be dealt with utmost vigilance to minimize the risks of spillage.

Along with being highly conductive to electricity, such a paste can corrode your system’s circuitry. 

If your CPU cooling heatsink is made of aluminum, note that applying a metallic-based paste will start a very hazardous reaction, corroding the aluminum away. 

Thus, it is necessary to either replace the heatsink with a nickel-plated copper heatsink or do not apply a corrosive paste in the first place. 

On the split end, thermal pastes based on ceramic, silicon, and zinc are non-corrosive which you can use for any sort of applications without chances of short-circuiting your computer components.

However, liquid metallic compounds are much better at dissipating heat. 

Grammage

Different thermal pastes of different sizes and volumes are retailed for different prices. What volume syringe will best fit you directly depends on your use. 

If you want to apply the thermal paste on your AMD or Intel CPUs, you should go for a product that retails lesser volume syringes.

Otherwise, if you have to use it on multiple systems then you certainly need one with more grammage. 

Some of you might be thinking of storing the left content and reusing it after some time when the initial application cracks out.

The answer to this is simple. It’s not sensible to reuse a cooling compound once opened. 

Usually, such compounds tend to expire soon after getting exposed to the atmosphere as they lose their cooling capacity. 

Hence, we recommend going with a 1 or 2-gram syringe if you intend to apply it on a usual size LGA 1151 socket or AM4 chips. For thread rippers or LGA 2066 CPUs, you should go with a bigger syringe that carries at least 3 grams of paste. 

Other Important Tips 

After considering these four essential aspects before purchasing any thermal paste, one should also look for secondary features such as the compound’s longevity, its application experience, bundled cleaning kits, and customer reviews. 

Firstly, don’t forget to find out whether or not your chosen product is handy enough to settle adequately even if you have no former knowledge of applying a thermal compound. Also, ensure that the product includes some extra helping tools like a spreader or controlling spatula that further aids you in your initial experience. 

Secondly, do bear in mind to check for its removal characteristics. Though reapplication of such compounds isn’t required too early, it is still good to consider a paste’s removal process beforehand so you could easily wipe it out when the time comes. 

Of course, everyone wants such a product that lasts longer and continues doing its work without a need for frequent changing. Therefore, do ensure that your chosen thermal paste has a greater life span. 

Frequently Asked Questions 

Should You Buy a Thermal Paste or a Thermal Pad? 

Thermal pastes/compounds have always turned out to function well than a more handy but less efficient thermal pad.

Thermal pads can accompany you if you are more into light gaming. They have a hassle-free application process and are much more user-friendly than a cooling paste.

However, if you are someone who tests their computer system to the peak of its capability, then cooling pads won’t support you for long.

So, if you require a cooling agent for everyday usage then the thermal pad is the right option for you, or else go with a thermal paste to achieve maximum cooling efficiency. 

How Much Thermal Paste Should You Use for the CPU? 

Using a conservative technique, a small amount will do the work and is quite better than going too much and making a mess. A small blob of thermal paste is more than enough and is spread properly.

Aiming for about the size of a small garden pea right at the center of the processing chip and spreading it evenly across the top is the only correct and recommended way.
