What is applied between the CPU and heatsink for better heat conduction?

What is Thermal Compound and Why is it so Important? Also called thermal paste, thermal grease, or conductive grease, this compound is a heat-conductive substance that is applied between the heatsink and the device it’s meant to cool. It improves conductivity between the heatsink and the CPU.

Should I use thermal paste or thermal pad?

The big advantage to thermal paste is its ability to be easily spread. It will conform to uneven surfaces very well, and fill large gaps more evenly than thermal pads. Another advantage is that with the ability to apply it as a thin layer, thermal paste can provide better thermal conductivity then the thicker pads.

Is heat sink the same as thermal paste?

Thermal paste (also called thermal compound, thermal grease, thermal interface material (TIM), thermal gel, heat paste, heat sink compound, heat sink paste or CPU grease) is a thermally conductive (but usually electrically insulating) chemical compound, which is commonly used as an interface between heat sinks and heat …

What’s the difference between a heatsink and a thermal pad?

In contrast, a heatsink thermal pad will become brittle over time after repeated thermal cycling, at which point the heatsink can break off the component. One other thermal interface material that has a similarly short lifespan is a thermal epoxy, which dries to a soft plastic material.

Which is better thermal grease or thermal pad?

Thermal paste, CPU thermal compound, or a thermal grease vs. thermal pad will adhere and solidify after application, whereas a thermal pad remains a spongy material. It will be a longer lasting solution and a less expensive option. This is particularly true under repeated thermal cycling.

When to use thermal pads or thermal paste?

In components that consume much more power, such as a high-performance FPGA or CPU, using a thermal pad or thermal paste is not where the debate ends. You’ll likely need to add a cooling fan to these components to ensure temperature is brought down to an appropriate level.

Which is more expensive thermal or liquid pads?

The more expensive thermal pads, thermally conductive pads, or thermal interface pads are usually made up of a rubber material and less likely to go the distance in terms of the wear and tear factor compared to the liquid competitor.
