There are many reasons why reapplying thermal paste is necessary. For example, if you notice your computer starting to overheat or the device’s fan sounds like it’s sputtering, this could be because of a lack of thermal paste.

Over time, the heat from the CPU can cause any existing thermal compound to break down and become ineffective in creating an even temperature between the CPU and its heatsink. Let us show you how to fix that issue by following these easy steps!

What is The Function Of Thermal Paste?

Thermal paste is an agent that fills the gaps between two surfaces (the processor and the heatsink) to improve heat transfer.

This allows the CPU to cool down more effectively while it operates under high loads, reducing its overall temperature and preventing it from overheating.

Thermal paste also helps disperse heat away from the component, preventing it from transferring to other parts of your computer’s enclosure and causing potential damage.

This way, thermal paste acts as a protective layer against excessive temperatures not only for the CPU but all major electronic components inside your PC enclosure.

Unlike thermal pastes, thermal pads are made of aluminum oxide, making them conductive rather than electrically insulating like thermal pastes.

How to Know When You Need to Apply Thermal Paste

Here are few reasons why you need to apply thermal paste:

  • The computer gets warm to the touch.
  • You see white dust particles or liquid on your CPU fan; this indicates thermal paste and reapplies immediately.
  • The computer starts to overheat or fan running more frequently.

Tips for Applying the Thermal Paste Correctly

Here is few tips help you to apply thermal paste correctly:

– Try to reapply the thermal paste as soon as possible; avoid putting off reapplying it because it will worsen the situation.

– The most effective way to apply thermal paste is from the tube and not the “squeeze-out-from-the bottle” method because you can control how much thermal paste you want to apply on a surface.

Important Preparations for Thermal Paste Application

Before reapplying thermal paste, make sure you prepare the following tools:

  • – A credit card or flexible plastic scraper
  • – Rubbing alcohol and a lint-free cloth
  • – A tube of the thermal paste
  • – A credit card like a piece of plastic to apply even pressure
  • – Computer case and a power supply with all parts removed for easy reapply of thermal paste.

How to Reapply Thermal Paste Correctly

Here is the step-by-step guide on how to apply thermal paste correctly without any damage. Scroll down!

Step 1: Prepare few tools that allow you to remove and reapply the old thermal paste from your CPU and heatsink.

Step 2: Remove the old thermal paste with a credit card or flexible plastic scraper. Make sure that you scrape straight down in one direction rather than in multiple directions to prevent damaging the base of your CPU.

Step 3: Clean the surface with rubbing alcohol and a lint-free cloth to ensure no residue or dirt is present.

Step 4: Hold the heat sink with one hand while reapplying the thermal paste with the other.

Step 5: Use a credit card-like piece of plastic to apply even pressure across the surface being reapplied. Apply only enough pressure to smooth it out; using too much will damage your processor and void your warranty!

Step 6: After applying, reapply a small amount of thermal paste, avoiding air bubbles as much as possible.

Step 7: Reapply the paste until you have a thin layer covering the heat sink.

Step 8: Cover with the heat sink without touching it; this will push any air bubbles out from under the edges of the heat sink.

Step 9: Place the fan back in place, reapply screws, and close the computer.

Step 10: After reapplying the thermal paste, turn on your computer and let it operate for about 30 minutes, then check if it reapplied correctly by overheating the protection program in the windows control panel or other similar tools. Check to see if the temperature is average and within a safe range.

Conclusion

Make sure your computer is functioning correctly and reapply only when needed. You don’t want to reapply too much, as this can cause damage, voiding warranties. Applying a new paste will not fix a damaged CPU!

Hope these tips help you out in the future and keep your system cool!
