Thermal paste, a Thermal Interface Material (TIM), is often included in a CPU or GPU cooler; however, it's usually recommended that you use a custom thermal paste instead of the pack-in option, and for good reason.

Polartherm X-8 and Polartherm X-10 thermal paste from Thermal Grizzly.
Polartherm, from Thermal Grizzly, delivers affordable, high-quality thermal paste solutions for improved cooling and optimal performance of components like a CPU. Polartherm X-8 and Polartherm X-10 are not only easy to use with three convenient application methods but also provide optimal heat transfer and the thermal conductivity to keep PC components cool, quiet, and stable, no matter the workload.
Thermal paste, like thermal pads or liquid metal, acts as a bridge for heat transfer. In the case of a CPU or GPU, it sits between the heat spreader and the attached cooler to fill microscopic gaps. It's a crucial part of the cooling process, especially when dealing with budget or affordable CPU coolers. A less effective thermal paste can lead to performance issues, overheating, and reduced product lifespan. This is where Polartherm X-8 and Polartherm X-10 thermal paste step in.
How does Thermal Paste work?
Thermal paste combines various ingredients; in the case of Polartherm X-8, a silicone oil-based carrier is mixed with aluminum and zinc oxide powder. This balance of particles and ingredients then determines the overall viscosity of the thermal paste and its thermal conductivity. The viscosity or thickness of the thermal paste often determines its ease of application, with low viscosity being easier to apply as it is more water-like in its makeup.
Polartherm X-10 is the perfect choice for incorporating into a high-performance air-cooled or water-cooled PC. It has a significantly higher viscosity as the ingredients or thermal paste formula includes a higher concentration of aluminum and zinc oxide powder. These particles in Polartherm X-8 and Polartherm X-10 thermal paste 'fill in the gaps' for effective heat transfer when applied to a surface like the top of a CPU, leading to lower temperatures and optimal performance for hardware-intensive workloads like gaming or video editing.
Polartherm Thermal Paste offers long-term stability
Long-term stability for thermal paste is all about delivering the same thermal conductivity and performance long after the first boot into Windows. One of the main reasons a CPU or GPU gets hotter and hotter over time is the pump-out effect. Due to temperature changes, a CPU's substrate and processor begin to warp at the microscopic level. After several heating-up and cooling-down cycles, this warping effectively leads to thermal paste being pumped out or away from hot spots or the central part of a processor, leading to higher temperatures.

A simple solution you've probably heard before is to reapply thermal paste or repaste to restore thermal conductivity and heat transfer. Polartherm X-8 and Polartherm X-10 thermal paste are excellent choices for this. Best of all, with Thermal Grizzly's expertise, their excellent durability is designed to resist and minimize the pump-out effect. This means long-term stability for enhanced thermal performance and longer-lasting components.
Polartherm X-8 and Polartherm X-10 Thermal Paste are available now
For cooling performance, durability, easy application, and affordability, look no further than Polartherm X-8 and Polartherm X-10 thermal paste. As mentioned above, both offer long-lasting performance that resists the pump-out effect with formulas to ensure your components stay cool. Both offer three application methods - direct to the CPU/component, the spatula method for spreading the compound across the CPU's surface, and the applicator method of applying thermal paste onto the heat spreader.
