If the thermal grease dries up, will it affect heat dissipation?

If the thermal grease dries up, will it affect heat dissipation?

It will definitely affect, but to varying degrees!


The core function of thermal grease is to fill the gap between the chip and the heat dissipation component to allow heat to be transferred smoothly. However, over time, thermal grease may gradually dry out, mainly because the oil in it evaporates, causing it to harden and lose its original soft state.

  • Slightly dry: There is still a certain degree of thermal conductivity, so the impact is small and there is no need to worry too much.

  • Completely dry and cracked: It may cause a significant decrease in thermal conductivity efficiency, poor heat dissipation, and even affect the performance and life of the phone.

Therefore, if your phone has been heating up frequently and its performance has declined recently, it is likely that the thermal grease has lost its effectiveness and needs to be replaced!


How to determine whether thermal grease needs to be replaced?

(1)The temperature of the phone rises abnormally when it is running

If your phone becomes hotter than before during daily use, even if you are just watching short videos or chatting, you can see it.

If frame drops, freezes, or frequency drops occur while playing games, it may be because the chip temperature is too high and the system has activated automatic frequency reduction protection.

(2) Battery consumption increases

Overheating of the mobile phone will cause the battery performance to decline, the battery life will be significantly shortened, and it may even accelerate the aging of the battery.

(3) After disassembling the machine, it was found that the thermal grease was cracked or hardened.

If you have some knowledge of mobile phone repair, you can take the back cover apart and have a look. If the silicone grease has completely hardened and cracked, it is time to replace it with a new one!


How to replace the thermal grease of a mobile phone?

Replacing the thermal grease is not complicated, but it requires certain operating skills.

Replacement steps:

(1) Prepare tools: new thermal grease, screwdriver, tweezers, dust-free cloth, alcohol cotton.

(2) Disassemble: Carefully remove the back cover of the phone and find the chip and heat dissipation part (if you have no experience, it is recommended to find a professional).

(3) Clean the old grease: Gently wipe the dry thermal grease with alcohol cotton to ensure the surface is clean.

(4) Apply new grease: Apply an appropriate amount of thermal grease evenly, avoid too thick or too little, to achieve the best heat dissipation effect.

(5) Reassemble and test: Turn on and run for a while to see if the heat dissipation effect is improved.


Note:

  • Choose high-quality thermal grease. Products with high thermal conductivity and strong durability can extend the service life.

  • Apply evenly, not too thick or too thin to avoid affecting the heat dissipation effect.

  • Keep the operating environment clean to prevent dust or impurities from affecting the chip contact surface.


How to extend the service life of thermal grease? 

In order to make thermal grease more durable, you can pay attention to the following points in daily use:

  • Avoid long-term high temperature environment and do not expose the phone to the sun for a long time.

  • Clean the dust on the phone regularly to keep the heat dissipation channel unobstructed.

  • Use official or high-quality heat dissipation solutions, such as heat dissipation back clips, to help reduce the temperature.

  • Reduce high-load tasks. Long-term tasks such as playing games and editing videos will accelerate the aging of thermal grease.


Summary

The thermal grease of the mobile phone has dried up, which affects the heat dissipation and needs to be paid attention to in time!

  • After the thermal grease dries, the thermal conductivity will decrease, which may cause the mobile phone to overheat, performance degradation, and even affect the service life.

  • If you find that the mobile phone is abnormally hot, the game is stuck, and the battery life is reduced, you may need to replace the thermal grease.

  • Replacing the thermal grease is not complicated, but you must choose a high-quality product and pay attention to the correct application method.

  • Paying attention to protective measures on a daily basis can extend the life of the thermal grease and maintain the longer-lasting heat dissipation performance of the mobile phone.
