Performance Benchmarks Of Different Thermal Pads And Pastes For Overheating Fixes

by

Overheating is a common issue in modern electronic devices, especially with high-performance CPUs and GPUs. Applying the right thermal interface material (TIM), such as thermal pads or pastes, is crucial for effective heat dissipation. This article presents performance benchmarks of various thermal pads and pastes to help users choose the best solution for overheating fixes.

Understanding Thermal Interface Materials

Thermal interface materials are substances placed between heat-generating components and heat sinks to improve heat transfer. They fill microscopic gaps and irregularities, ensuring efficient thermal conduction. The main types include thermal pastes, pads, and gels.

Test Methodology

Benchmarks were conducted on a standard test rig with identical CPUs and GPUs. Each thermal pad or paste was applied according to manufacturer instructions. Temperature readings were taken under load using stress-testing software, recording the peak temperatures over a 30-minute period.

Thermal Pastes Tested

  • Arctic MX-4
  • Noctua NT-H1
  • Thermal Grizzly Kryonaut
  • Ceramique 2
  • Cooler Master MasterGel Maker

Thermal Pads Tested

  • Gelid Solutions GP-Extreme
  • Thermal Grizzly Minus Pad 8
  • Phanteks PH-FF122
  • Cooler Master MasterGel Maker Pad
  • Alphacool Eisblock GPX

Benchmark Results

Results indicate significant differences in thermal performance among the tested materials. Thermal pastes generally provided lower peak temperatures compared to pads, but some high-quality pads approached paste performance in specific scenarios.

Thermal Pastes Performance

  • Kryonaut: Achieved the lowest peak temperature of 65°C under full load.
  • MX-4: Slightly higher at 68°C, but excellent value for money.
  • NT-H1: Peaked at 69°C, reliable and easy to apply.
  • Ceramique 2: Reached 72°C, good for budget builds.
  • MasterGel Maker: 66°C, comparable to Kryonaut.

Thermal Pads Performance

  • Minus Pad 8: Peaked at 75°C, best among pads tested.
  • GP-Extreme: 77°C, decent for moderate cooling needs.
  • Phanteks PH-FF122: 78°C, suitable for less demanding applications.
  • MasterGel Pad: 80°C, higher than other pads but still functional.
  • Eisblock GPX: 82°C, the least effective in this group.

Factors Influencing Performance

Several factors affect the effectiveness of thermal interface materials:

  • Thickness: Thicker pads may insulate heat, reducing performance.
  • Conductivity: Higher thermal conductivity materials transfer heat more efficiently.
  • Application: Proper application ensures maximum contact and minimal air gaps.
  • Material Stability: Long-term stability prevents performance degradation over time.

Conclusion

For optimal cooling, high-quality thermal pastes like Kryonaut or MX-4 are recommended for critical components. Thermal pads can be suitable for less demanding applications or where ease of installation is prioritized. Selecting the right TIM depends on the specific cooling requirements, budget, and application scenario.
