Replacing thermal pads with thermal putty is a viable option in certain situations, but it's important to consider a few factors before making the switch:

1. Thermal Conductivity

Thermal pads and thermal putty have different thermal conductivities. Thermal pads are generally less conductive compared to thermal putty or paste. If you replace thermal pads with thermal putty, make sure the putty you choose has a similar or higher thermal conductivity to ensure effective heat transfer.

2. Thickness and Gap Filling

Thermal pads are available in various thicknesses and are designed to fill gaps between components. Thermal putty, on the other hand, is a semi-liquid material that can conform to uneven surfaces and fill small gaps. If you decide to switch to thermal putty, ensure that it provides sufficient contact and fills any gaps between the components.

3. Application and Reusability

Thermal pads are convenient to use as they come in pre-cut shapes and can be easily replaced or repositioned. Thermal putty, however, requires careful application to ensure an even and thin layer. Additionally, thermal putty may not be reusable and may need to be re-applied each time the heatsink is removed.

4. Stability and Electrical Conductivity

Check the electrical conductivity of the thermal putty before using it. Some thermal putties may have conductive properties, which could lead to short circuits if they come into contact with sensitive electrical components. Make sure the putty you choose is non-conductive and safe for use with your specific components.

Before replacing the thermal pads, thoroughly research and select a high-quality thermal putty that meets the requirements of your electronic system and offers suitable thermal conductivity. Follow the manufacturer's instructions for proper application and ensure that It's compatible with your components.

If you have any doubts or concerns, it's recommended to consult with the thermal material manufacturer or seek professional advice to determine the best thermal management solution for your specific electronic system.
