How to Choose the Right Thermal Paste or Pad
When selecting a thermal interface material, consider:
- Compatibility: Is your application a CPU, GPU, power MOSFET, or generic heatsink?
- Performance: Higher thermal conductivity (W/mK) is better for overclocking, high-power, or dense electronics.
- Ease of Use: Pads are simpler for surface-mount modules and irregular shapes; pastes give better fill for CPUs/GPUs.
- Thickness/Gap: Measure the clearance between components - 1.0mm or 1.5mm pads are common for RAM/VRM, while most CPUs use paste.
Application Example: PC Repaste
Say you’re rebuilding a desktop PC. Remove the old heatsink and thermal paste, tidy both surfaces with alcohol, then apply a small "pea-sized" dab of fresh paste (silicone or ceramic-based, non-conductive unless specified). Reinstall the heatsink with even torque on screws. Result: Lower temperatures and improved system stability.
