Liquid Metal vs Thermal Paste – 2025
Liquid Metal vs Traditional Thermal Paste in 2025: Which One Should You Trust?
As CPU and GPU performance continue to climb in 2025—especially with the rise of Intel’s Arrow Lake processors and the AMD Ryzen 9000 series—thermal interface materials (TIMs) have never been more critical. But should you go with high-performance liquid metal or tried-and-tested thermal paste?
💡 What Are Thermal Interface Materials (TIMs)?
Thermal compounds are used to fill microscopic air gaps between a CPU/GPU die and its heatsink or cooling plate. Without this layer, thermal transfer is inefficient, causing overheating and throttling.
⚙️ Material Composition: What’s Inside?
- Liquid Metal: Mostly composed of a Gallium-based alloy (like Gallium-Indium-Tin). Offers extremely high thermal conductivity but is electrically conductive and corrosive to aluminum.
- Traditional Paste: Made from ceramic, carbon-based, or metal oxide compounds (e.g., zinc oxide or aluminum oxide). Non-conductive and user-friendly.
📊 Thermal Conductivity Benchmarks (W/m·K)
- Thermal Grizzly Conductonaut Extreme (Liquid Metal): 73.0
- Cooler Master MasterGel Maker Nano (High-End Paste): 11.0
- Arctic MX-6 (Standard Paste): 8.5
- Stock Pastes (OEM): 2–4
🧪 Real-World Performance: Gaming & Workstation Impact
Tests on CPUs like the Intel Core i9-14900KS and Ryzen 9 9950X show up to 10–15°C lower temperatures when using liquid metal over even the best traditional pastes—especially under full synthetic workloads or when overclocked.
However, in thin-and-light laptops or consoles (like the PS5), traditional paste remains safer and more consistent long-term.
🔧 Application and Risk Profile
- Liquid Metal: Requires masking nearby SMDs, cannot touch aluminum, and must be applied in a paper-thin layer with applicators. Great results but high risk.
- Traditional Paste: Easy to apply (pea-sized drop or X-pattern), safe on all materials, and beginner-friendly.
📅 Longevity and Maintenance
- Liquid Metal: May last 1–2 years depending on the seal and usage. Risk of oxidation or pumping out over time.
- Thermal Paste: Premium pastes can last 4–5 years with stable performance, no reapplication needed unless temps rise.

📌 Bonus Tips
- Always clean surfaces with isopropyl alcohol before reapplying any TIM.
- Don’t reuse old thermal paste or metal—it degrades over time and traps heat.
- If you switch from paste to liquid metal, make sure to remove any aluminum heatsinks.
