When Should You Change Thermal Paste?

Indicators for Reapplication [00:00]

• Increased system noise is a primary indicator that thermal paste may need reapplication.
• Higher fan speeds, evidenced by noise, mean the system is working harder to cool components.

  An increase in noise tells me that my system fans are working harder in order to keep my system cool.

Causes of Increased System Noise [00:21]

• Two main reasons for increased fan activity: dust buildup in fans or heatsinks, or dried-out thermal paste.
• Thermal paste degrades over time, reducing its effectiveness in heat transfer.

  There's two main reasons for that. Either I have a lot of dust buildup in my fan or my heat sink, or my thermal paste is starting to dry out.

Thermal Paste Lifespan [00:28]

• Most thermal pastes are rated for a specific number of thermal cycles.
• Consistent low temperatures prolong paste life, while fluctuating high temperatures can reduce it to a couple of years.

  But if your temperatures are typically elevated and fluctuating all the time, it could happen as fast as just a couple years.

When to Reapply [00:43]

• There is no downside to changing thermal paste proactively.
• If you feel uneasy about your system's thermal performance, it's advisable to reapply the paste.

  There's no downside to changing your thermal paste early. So, if you're feeling uneasy for whatever reason, go for it.

Caution with Liquid Metal [00:48]

• Avoid touching liquid metal thermal compounds unless you have specific expertise.
• Liquid metal requires careful handling and application.

  Unless your system uses liquid metal, don't touch that stuff unless you know what you're doing.
