Guide on How to Apply Thermal Paste and Thermal Pads to Various Devices

Thermal paste and thermal pads are both used to improve heat transfer from a component (like a CPU or GPU) to its cooler or heatsink. Thermal paste is a liquid-like substance, while thermal pads are solid materials that serve a similar function. Below is a guide on how to apply them to different devices.


1. PC (Desktop Computer)

Thermal Paste

What you’ll need:

  • Thermal paste
  • Isopropyl alcohol (90% or higher)
  • Lint-free cloth or paper towel
  • Small plastic card or spatula (optional)

Steps:

  1. Power off and disconnect the PC from the power source.
  2. Remove the side panel and locate the CPU cooler or heatsink.
  3. Remove the heatsink: Undo screws or mounting mechanisms and carefully lift the cooler off the CPU.
  4. Clean the CPU and heatsink: Use isopropyl alcohol and a lint-free cloth to remove any old thermal paste from both the CPU and heatsink.
  5. Apply thermal paste: Place a small, pea-sized dot of thermal paste in the center of the CPU.
  6. Reattach the cooler: Carefully place the cooler back onto the CPU, ensuring even contact with the thermal paste. Tighten the screws or mounting system.
  7. Reconnect everything and power up the PC.

Thermal Pads

Thermal pads are typically used for components like VRMs, memory chips, or the GPU on a PC.

What you’ll need:

  • Thermal pad
  • Scissors (to cut the pad to size)
  • Isopropyl alcohol (optional)

Steps:

  1. Clean the surface: Use isopropyl alcohol to clean the area where the thermal pad will sit (e.g., on VRMs or GPU).
  2. Cut the thermal pad: Cut the pad to the appropriate size to cover the chip or area you need to cool.
  3. Place the thermal pad: Peel off the protective film from both sides of the thermal pad and carefully place it onto the surface.
  4. Reassemble the PC: Mount the cooler back onto the component, ensuring it makes good contact with the thermal pad.

2. Laptop

Thermal Paste

What you’ll need:

  • Thermal paste
  • Isopropyl alcohol (90% or higher)
  • Lint-free cloth or paper towel
  • Small screwdriver

Steps:

  1. Power off and unplug the laptop.
  2. Open the laptop: Remove the screws and back panel to access the CPU or GPU.
  3. Remove the heatsink from the CPU or GPU.
  4. Clean the surfaces: Use isopropyl alcohol to clean both the chip and heatsink, removing any old thermal paste.
  5. Apply thermal paste: Apply a small, pea-sized dot of thermal paste to the center of the CPU or GPU.
  6. Reattach the heatsink: Place the heatsink back onto the CPU/GPU and tighten the screws.
  7. Reassemble the laptop and power it on.

Thermal Pads

What you’ll need:

  • Thermal pad (pre-cut or large sheet)
  • Scissors
  • Isopropyl alcohol (optional)

Steps:

  1. Clean the surface: Use isopropyl alcohol to clean the area where you will apply the thermal pad (e.g., around the memory chips or VRMs).
  2. Cut the thermal pad: If using a large sheet, cut it to fit the area.
  3. Place the thermal pad: Peel the protective film off the thermal pad and apply it to the clean surface.
  4. Reassemble the laptop and secure everything back in place.

3. Game Console (e.g., PS4, Xbox)

Thermal Paste

What you’ll need:

  • Thermal paste
  • Isopropyl alcohol (90% or higher)
  • Lint-free cloth or paper towel
  • Small screwdriver

Steps:

  1. Power off and unplug the game console.
  2. Disassemble the console: Remove the outer casing and any internal components to access the CPU/GPU (following a model-specific guide).
  3. Remove the heatsink from the CPU or GPU.
  4. Clean both surfaces: Wipe off any old thermal paste using isopropyl alcohol.
  5. Apply thermal paste: Place a small, pea-sized dot of thermal paste in the center of the CPU/GPU.
  6. Reattach the heatsink and secure it.
  7. Reassemble the console and power it on.

Thermal Pads

What you’ll need:

  • Thermal pad
  • Scissors
  • Isopropyl alcohol (optional)

Steps:

  1. Clean the area: Clean the surface where you’ll apply the thermal pad (e.g., memory or VRMs) with isopropyl alcohol.
  2. Cut the thermal pad to size.
  3. Place the thermal pad: Peel the protective film and place it on the cleaned surface.
  4. Reassemble the console and power it on.

4. LEDs (LED Strips, Cooling Fans, or High-Power LEDs)

Thermal Paste

What you’ll need:

  • Thermal paste
  • Isopropyl alcohol (90% or higher)
  • Lint-free cloth or paper towel

Steps:

  1. Check if thermal paste is needed: Most typical LEDs (like strips or low-power LEDs) don’t need thermal paste. However, high-power LEDs (used in specialized cooling systems) may require it.
  2. Clean the surfaces: If applying thermal paste, use isopropyl alcohol to clean both the LED and heatsink.
  3. Apply thermal paste: Place a small, pea-sized dot of thermal paste on the back of the high-power LED or its heatsink.
  4. Reattach: Carefully press the LED against the heatsink to spread the thermal paste evenly.

Thermal Pads

What you’ll need:

  • Thermal pad (usually thin, pre-cut for LEDs)
  • Scissors (if cutting to size)
  • Isopropyl alcohol (optional)

Steps:

  1. Clean the surfaces: Clean both the LED and heatsink with isopropyl alcohol if necessary.
  2. Cut the thermal pad: If needed, cut the thermal pad to size.
  3. Place the thermal pad: Peel off the protective films from both sides of the thermal pad and apply it to the LED or heatsink.
  4. Reassemble: Attach the LED to the heatsink, ensuring the pad makes good contact.

General Tips for Both Thermal Paste and Pads:

  • Use the right amount: A small, pea-sized dot of thermal paste is usually enough. Thermal pads should cover the entire surface area needing heat transfer.
  • Avoid air bubbles: Ensure good contact between the thermal paste or pad and the components to prevent air pockets that can affect heat dissipation.
  • Reapply when necessary: Thermal paste and pads degrade over time, so it’s advisable to replace them every few years.

This guide provides a general overview for applying thermal paste and thermal pads to different devices. Always consult device-specific instructions, especially when disassembling laptops, consoles, or other devices.
