Can You Use Thermal Paste Instead Of Pads? Things You Didnot Know!


Thermal paste and thermal pads usability are almost the same. So, if their workability is the same, can you use thermal paste instead of pads?Yes, you can. Still, there remains a butas thermal pads perform much better.

In this article, you will know about thermal paste, thermal pads, and obviously when you use thermal paste instead of thermal pads as well.

Can You Use Thermal Paste Instead Of Pads?

Thermal paste, often known as thermal gel, is an excellent substitute for thermal pads. Each paste has a few advantages beyond thermal pads, including automating, lower impedance (in specific material circumstances), and higher conformance to irregular surfaces.

However, the thermal paste can be used if such surfaces of your memory chips are pretty much the same size as the primary GPU chip. But, if they’re considerably shorter, then thermal pads might be preferable.

If you’re now searching for a quick fix, consider using thermal paste where:

  • Your annual production requirements are in the range of 5,000 units.
  • Complex or complicated designs are used in the layout of your parts.
  • Your components are sensitive due to the modest mechanical stress caused by the paste.

What is Thermal Paste?

The thermal or cooling paste is among the most common thermally conductive compounds used throughout heatsinks and CPUs. The highest-quality pastes will deliver the best possible results whenever it comes to dispersing and transferring heat. Thermal paste seems to be:

  • A suitable solution enables heat dissipation towards the heat sink since it stays for an extended time.
  • Each component surface gets thoroughly wetted thanks to a coating of thermal paste.
  • The paste covers every micro-depression on that component or even underside because it’s a viscous fluid.
  • So, the heat sink receives substantially more heat dissipation.

However, the application is challenging, especially for beginners, leading to problems. Unlike certain other forms of thermal pads, Thermal paste isn’t designed to span longer distances.

What is Thermal Pad?

Thermal pads are easier to install because they are more flexible. They can easily fit without effort and come with various heat sinks that have already been installed. Even newcomers will have no problems. Thermal pads are pretty common in the industry.

  • Unfortunately, such materials’ total thermal conduction isn’t often as impressive as the thermal paste.
  • Though little gaps may occur between both the processors as well as the thermal pads, you can see it there.
  • These narrow air pockets give a poor thermal conductivity since air is relatively low heat-conducting.

It’s essential to remember that such a thermal pad has always been a one-time fix. As a result, if this heat sink needs to be moved or updated, it must be done so. In that case, you must ensure to remove every residue of adhesives.

Otherwise, more bumps, as well as gaps, may appear. Rather than simply wiping the surface clean, the thermal paste should be scrapped entirely and replaced.

Thermal Pad Or Thermal Paste?

So, which is preferable: thermal pads or thermal paste?

Use Thermal Pads for

  • This material is comfortable to manage with, and it can slice into custom sizes.
  • Thermal pads are available in a variety of materials, enabling them to be customized for specific applications.
  • On the other hand, thermal pads are more pricey, and their slicing and installation add to the production time of your required circuit board.

Use Thermal Paste for

  • The paste is highly dependable in a variety of applications.
  • This is easy to apply, fills irregular gaps, and creates a thinner contact for improved thermal conductivity.
  • On the other hand, it’s sticky and prone to drying up, and it’s not as mechanically strong as a pad.
  • In general, thermal paste is not costly and is more affordable than thermal pads.

Frequently Asked Questions (FAQs)

Why are thermal paste and pads used in electronic devices?

Neither the CPU nor the heat sink has perfectly smooth surfaces. There’ll be microscopic bumps, crevices, and gaps inside the components that allow air to travel through. Because air is a poor heat conductor, such gaps have a significant detrimental impact on heat transfer.
To cover these gaps or enhance thermal conductivity between the CPU and the heat sink, thermally conductive materials with high conductivity are required.

What are the drawbacks of thermal pads?

Thermal pads aren’t reusable. When components are removed, they should be managed with extreme care, particularly once the pad gets attached to the applications of the other components.

Why shouldn’t you use thermal paste and pads at the same time?

It’s preferable to avoid combining paste and pads. Even if they’re utilized together doesn’t mean they’ll perform a better job of transferring heat. Contrary to prevalent belief, this isn’t the case.

Conclusion

Can you use thermal paste instead of pads– you ask? It’s critical to understand the thermal interface material required for an application with such gap fillers.

Generally, fillers are utilized in a wide variety of situations, depending on the nature of the application. During installation, it requires extremely precise placement and pressure.

Therefore, before using thermal paste in place of pads, you should understand the difference between thermal gap pads and thermally conductive paste, as well as which material is best for your application.
