Thermal Paste

MX thermal pastes have been classics on the market for over a decade and are among the most popular and best-selling ARCTIC products. With extremely low thermal resistance due to a thin bond line, simple and safe application, long durability and a customer-friendly price-performance ratio, they are the ideal addition to any CPU and GPU cooler.

THERMAL PASTE WITH HIGH PERFORMANCE AND EASY APPLICATION

Thermal Paste (also known as cooling paste) is the most frequently used option for heat transfer between the CPU and the CPU-Cooler. The best performance is achieved with high quality pastes.

1. What do you need thermal paste for?

The surface of a heatsink is never completely flat. Its surface is covered with microscopic abrasions caused by the manufacturing. Direct contact would create air spaces that have an insulating effect on heat transfer. Therefore, a filler material with very good thermal conductivity is required to compensate for the unevenness between the cooler and the chip and to fundamentally improve the heat transfer. The problem with metal fillers, even though they have excellent thermal conductivity, is their electrical conductivity. Non-electrically conductive pastes usually offer significantly lower thermal conductivity. However, it is possible to press out the compound to a significantly thinner layer thickness. The thermal resistance takes into account both the bond line thickness (= layer thickness) and the thermal conductivity.

Thermal Resistance = Bond Line Thickness / Thermal Conductivity

 

Delta T (Temp difference between CPU and Cooler) = Thermal Resistance x Energy (to be transferred from CPU to Cooler)

Instead of thermal paste can be also used Thermal Pads, especially when bridging larger distances. Thermal pads generally conduct heat better than thermal paste however, a very thin bond line is not possible with them.

2. How do I apply Thermal Paste?

First of all, the surface of the chip should be cleaned thoroughly. We recommend the blob method - in which the thermal compound material is applied to the centre of the CPU and evenly distributed without creating air pockets by placing the cooler on top. It is only important that the entire surface of the processor is covered by a thin film. Thanks to their consistency, ARCTIC thermal pastes are easy to apply, even for beginners.

3. How do I remove old Thermal Paste?

Fresh thermal paste is often easy to wipe off. If it has already dried up, it is recommendable to wipe it off using a cloth with lime. Stubborn hardening can be wiped off with light pressure.

 

4. How long does Thermal Paste last and when does it need to be replaced?

General statements regarding the shelf life of thermal paste once applied cannot be made. While some pastes have to be renewed regularly to prevent drying out, ARCTIC’s thermal pastes offer a very long shelf life of at least eight years. Our syringes are resealable, so you basically don't have to worry about drying them out prematurely. Even when applied, our paste convinces with its durability. As soon as you feel changes in the temperature, the noise level or the performance, you should clean your PC and replace the thermal paste.

5. Which Thermal Paste performs best in tests?

Thanks to its outstanding performance, the ARCTIC MX-4 has received multiple awards and is one of the top thermal pastes of the market. ARCTIC recently added a new premium thermal compound to its portfolio. The MX-5 impresses with ideal thermal properties, guaranteeing reliable heat dissipation over long periods of time.

6. Which packaging sizes do we offer?

Thermal paste is usually available in packaging sizes of a few grams, which is sufficient for several applications. Syringes are employed for precise application. At ARCTIC, the  MX-5 is available in packaging sizes from 2 to 50 grams, the MX-4 up to 45 grams. Alternatively, variants with a spatula are available. The ARCTIC MX-2 is offered in tubes from 2 to 65 grams. 

Our in-house thermal paste is also applied or included in many of our CPU-Cooler in advance.
