The 18 Best Thermal Paste Products For Cpu/gpu of September 2023

Why do we need the best thermal paste products?

An electronic device emits a significant amount of heat while in operation. A passive heat exchange component, the heat sink is used to mitigate the heat generated by regulating heat from the device using a liquid or air coolant to dissolve heat produced to avoid overheating. However, you might need to get a thermal paste to keep the processor running at healthy temperatures. This piece is a thermal paste comparison that narrows down to the best thermal paste products.

A thermal paste is a heat-conductive compound that is introduced between an AC cooler and CPU or between the heat sink and device it is required to cool. The compound improves the conduction of heat by filling the tiny spaces in the coolers, CPUs, and heatsinks. Thermal pastes are highly effective if your processor runs too hot even at low temperatures. The best thermal compounds are ceramic, silicon, carbon-based, and metallic material.

Non-conductive: the best thermal paste should be less conductive to ensure that you are safe from a short circuit when interacting with the electrical components. To reduce further risks of a short circuit, you should apply a pea-sized amount and let the heatsink spread the paste. You should select a product that is recognized as an effective non-conductive component.

Density: You can introduce the thermal paste is between the CPU and its cooler to protect the system from overclocking. The best thermal paste for the CPU has an adequate amount of density, allowing it to squeeze throughout the system easily. The liquid thermal paste is less dense compared to the normal thermal paste. Getting the right density ensures that you can cool down all your processors effectively with much ease.

Thermal Conductivity: Thermal conductivity determines the transfer of heat from the processors to the heatsink. A good thermal paste has a high thermal conductivity rating in addition to high reliability and versatility. When thermal conductivity is greater than temperature, it is reduced faster and more efficiently. Liquid thermal pastes have a conductivity of up to 70W/mK, while non-metallic compounds have a conductivity falling between 4-10W/mK.

Types of Thermal Paste

Hybrid thermal paste: The hybrid thermal paste contains different particles that form a single thermal paste. The mixture is composed of metal oxides, metal particles, and other particles. The hybrid thermal paste is highly effective in the delivery of excellent performance and is also effective for overclocking.

Carbon-based thermal paste: The carbon bases thermal paste works almost as efficiently as the metal-based thermal paste. The compound is made of carbon particles such as graphite oxide as a filler, graphite powder, and diamond powder. It has high thermal conductivity, non-conductivity, and non-capacitive characteristics. The paste is slightly expensive compared to the silicon and ceramic-based thermal pastes.

Metal-based thermal paste: The metal-based thermal pastes are quite expensive but quite effective in the delivery of optimal performance for your devices. The paste contains metal particles acting as fillers. The compound has high thermal conductivity ratings, making it effective for overclocking purposes and use in high-performance gaming PCs. Due to the capacitive and conductive properties, you need to exercise caution to avoid short circuitry.

Silicone/ceramic-based thermal paste: The ceramic/ silicone-based compounds use ceramic powder or metal oxides suspended in silicone compounds. The thermal paste is rich in non-conductive properties. The general performance of the compound depends on the metal oxide in use. You should avoid a paste made of pure silicone if you need to get the best results.

How Thermal Paste Works?

The paste fills the gaps between the processing unit and the heatsink allowing it to cool quickly and maintain a constant connection. The thermal paste flows nonstop in liquid form to ensure that the system is safe from overheating. The paste has a temperature limit of 150ºC, while some thermal pastes can withstand up to 300ºC. You can opt for silicon-based, metal-based, ceramic-based, or carbon-based thermal paste.

How to Apply Thermal Paste?

The application of thermal paste might seem simple but is overwhelming for first-timers. With time, you can master the skill of applying the thermal paste effectively using the heatsink. You need to apply the component effectively to reduce the chances of causing damage to the internal components of your device.

While using carbon or ceramic-based thermal paste, you shall need to squeeze a small amount over the contact area of the heatsink and the CPU. When you press the two pieces together, the paste spreads out to fill the air spaces. Some ceramic pastes come with a spreader and a thermal pad that make your work in the application much simple.
