Arctic Silver 5 Thermal Compound

This is a package of two 3.5-gram applicators, which offers you plenty of use on any products that need heat reduction. Anywhere from 20 to 30 small CPUs will be covered with this amount of thermal paste. It’s made from micronized silver, which is a very rare thermal paste choice making this a rather unique but effective product. The silver provides a smooth touch and is better at conducting heat than many other materials used in thermal pastes.

Our Honest Review

Very few other thermal paste products are made with silver as their base ingredient. Arctic Silver 5 Thermal Compound focuses their design on the use of silver and have made quite a name for themselves in doing so. This 99.9% pure silver is surprisingly conducive and great for heat transfer. This product will do amazing work in preventing overheating in your computer and assisting with overclocking. Application of this product is simple as well as the tube provides the perfect amount of control.

The main difference between this product and the Kryonaut or the MX-4 – besides the silver base – is the need for a set time. Many other products on our list can be applied and are ready to go, but this product requires time to set before you can reassemble the computer. This helps in consistency and performance and is well worth the wait we’ve found. It’s also not electrically conductive, which will help prevent short-circuiting.

Pros

  • Pure silver base product
  • Setting time helps smooth out paste
  • Better performance after setting

Cons

  • Setting time required before use

Factors to Consider When Shopping for Thermal Paste

Below we have listed some of the most important features to keep an eye out for when shopping for a thermal paste. While it might not be pivotal to have the greatest paste in each of these categories, it certainly will improve performance if the paste you choose scores high in each feature. The three following features are what we looked for when compiling our list of pastes. Each item on our list takes these into account and offers you the best combination of each feature. You don’t want a cheap material that comes in a large container and is difficult to remove.

Materials the Paste is Composed of

There are countless variations of thermal pastes available. The main difference between these pastes is the materials used to make them. Each type of material has its advantages and disadvantages, so it’s important to know which material your paste consists of. Silicon-based pastes are cheaper and less conductive of electricity than their metal counterparts. This lessens the chance of short-circuiting, but also lessens the amount of thermal conduction.

Carbon-based paste can be a tad expensive, but not as effective as metal-based pastes. It’s more conductive than silicon, but also more expensive. Hybrid thermal pastes will vary based on what materials are used. A hybrid paste can consist of any combination of metal or metal oxide. These are the best pastes for overclocking.

Size

The issue with many thermal pastes is their shelf life. It might be exciting to get the largest option available and to store up on thermal paste for when it runs out and needs to be reapplied. However, this isn’t always the economically smart choice as you could end up with a batch of useless paste that surpassed its shelf life. Many of the best thermal pastes come in small tubes of 5-gram maximums for a reason.

If you’re getting a thermal paste that will last for many years at a time, you won’t want to blow the bank on a large tube of product as chances are you won’t need it. With products like Grizzly thermal paste, you’re looking at a small tube because the paste has a longer use life, so reapplication won’t be necessary all that often.

Ease of Application and Removal

Some pastes can be quite difficult to remove without damaging the CPU. If the paste you’re looking at isn’t easy to remove, then you might want to find a different compound. There’s no point in using the thermal paste if it’s simply going to damage your CPU every time you try to remove it. The best thermal pastes are easy to apply and safe to remove. The application process should consist of four small dots on the corners of your CPU spread out to form a paper-thin layer of paste.

Frequently Asked Questions

Your thermal paste will act as the buffer between components of your computer, so you don’t want to mess up and purchase a paste that won’t hold its own. Protecting your CPU is quite important, and the right paste can do just that. Finding the right paste is all about knowing what questions to ask while shopping. We’ve compiled a list of some of the most important and frequent questions you should be considering while shopping for your perfect paste.

How long will my thermal paste last?

Your thermal paste should last a few years, at least. Many pastes will have a storage time of around two to three years and should be applied before this time runs out. Once applied, a thermal paste should last anywhere from two to five years before it needs to be retouched. Some thermal pastes will have even longer lives lasting up to eight or ten years in storage and application. If the paste has any shorter of a life than two years, you might want to search for a different product.

What is thermal paste made out of?

Thermal pastes can be made out of a number of different materials. The base material that the paste is made out of will affect how it works for your computer. The most common material would be metal-based pastes which have a high conductivity and are quite effective. A cheaper material would be silicon-based pastes which are more affordable, but less conductive. Carbon pastes are the middle child of those two, and hybrid pastes are great at preventing overclocking.

What is the best thermal paste for my computer?

This depends on what your intentions are for your computer. If you’re likely going to experience plenty of overclocking and heavy use, you’ll want a paste that can handle plenty of overtime work. If you’re not going to be as strenuous of a user, a silicon-based paste might be the safer option. Each of the pastes on our list is fantastic options to help keep your CPU cool, no matter how strenuous the use.
