Thermal Pastes

TG-600 Series is a thermal interface material, which is highly flexible & has good thermal conductivity in the vertical (z-plane) direction. The material is a single component, silicone-based and thermally conductive gap-filling material. This material has good thermal conductivity with its low thermal resistance properties. Due to its soft material properties, it is suitable for applications with large gap tolerances to improve heat transfer performance between 2 compressed surfaces.

What is thermal paste and CPU paste?

Thermal paste (also known as Thermal Oil or Thermal Compound) provides heating agent for CPU heat dispersion devices to use. Its primary material is zinc oxide. High heat can seriously damage components quickly. This includes high end graphics cards and processing units. We have heating systems that prevent this problem. Thermal paste is a heat sink used as a power source to warm a processing unit.

Thermal paste is also known as thermal grease and heat paste, CPU paste, thermal gel and thermal Interface (TIM) material and is important to understand how it functions and if it applies correctly. The proper application of thermal paste is crucial because it guarantees that an CPU is working correctly. Find out about thermal paper here. Use it to ensure the CPU temperature’s proper.

Liquid metal compound

Thermal paste was designed to minimize microscopic air gaps between cooling surfaces and the CPU’s IHS. Thermal paste can be electrically conductive or nonconductive. Liquid metals will need more attention during their application. Classic thermal paste composition can vary significantly depending on the experience level. Some budget pastes come awfully close to or surpass their cheaper competitors. We have completed extensive testing of some of the best thermal pastes on the market and if you’re on the hunt for exotic pastes that don’t follow the normal route we also have an extensive historical test.

Thermal Paste Results

Liquid metal compounds enter at the top of the heat charts with slightly cooler values than the traditional pastes. It is apparent LM is an outlier on this subcategory because of its budget price point and its budget. Most good and best heating compounds perform identically, except that price may be different every gram. Not every system will need every costly compound and even the very best system designers may find it very helpful to make low-cost mixes and/ or other forms of mortar. Thermal compounds are always compared but the fact remains: PC systems need thermal compounds to effectively dissipate thermal loads.

How does thermal paste work?

In order for CPUs to work efficiently they must be well cooled. Thermal paste is a silvery-gray material you apply into a processing machine before installing a cooling solution. The CPU temperature-regulating system uses mostly air or water to reduce cooling effects and heat generated from operating the CPU. If you wanted to find out how your CPU is built you can see the process for manufacturing it. If the computer as body is the CPU – the brain has absolute importance in the system functions. Modern CPUs run many operations per second thus producing heat. The thermal paste in that case is crucial.

When do you need to apply thermal paste?

If people think about gpu thermal pastes when building PCs they’re talking about installing a CPU cooler. When you buy graphics cards thermal solutions are incorporated already in them. You don’t usually have to worry about installing a cooler on a GPU, except for Aftermarket solutions such as custom Liquid Cooling. With coolers you have the option to choose what you want to use, but that means you usually have to do this yourself. For example you can specify what cooler you use, but first you must choose a cooler you want.

Why do you need thermal paste?

Thermal paste fills the air gaps between metal base of the CPU cooler and IHS of the CPU cooler. Metal plating have microscopic defects which can lead to poor heat transfers. Cooler CPU reduces the potential for performance problems like throttling. Thermally conductive paste helps coolers work efficiently. A cooler CPU means less performance issues. In spite of these imperfections the two faces are not in full contact so thermal paste can make them fill up this gap for a.

How often should I replace thermal paste?

You should not have to repeat application of thermal paste for more than a few years. If you have questions, consult the material supplier and follow the recommended directions. You may even have to try adding thermal paste to your CPU to cool the CPU.

Important preparations for thermal paste application

Most CPU coolers use thermal pastes that can be pre-applied in order to minimize the initial installation. Check the bottom of the base plate or waterblock of your cooling unit that mounts to the processor. If silver paste exists, you don’t need the same in the install process. If it has already been applied the thermal paste is easier to tell. The thermal paper is a safer option to use when a heat exchanger is in use than adding more ice. For example the procedure for install a CPU cooler.

Air-based heat sinks

A heat sink is the piece of technology used to transfer heat into a CPU and keep your CPU cool. Traditional air heat sinks use a metallic base that touches the processor. The energy is transferred via the block of metal to the copper pipes. Copper pipes are also secured to thin steel plates with fan blowing over them to further deflect heat. Heat sinks are mounted on a CPU heat spreader or IHS.

Thermal paste has often been overlooked by many new computer installations. Pre-applied thermal paste is acceptable but often very old and has spent months in the box. Thermal paste must be changed every year so it does not become dry. We should look into what the most popular thermal paste on the market.


It represents how thick the thermal paste is. The viscosity which relates to the viscosity is higher. When too much pressure is applied to the motherboard it could damage this paste. It may not be as important as it is that the high viscocoction can guzzle quickly into your processor. A highly-viscoseable thermal solution is more secure on a processor.
