Problem & Solution

Thermal throttling is the silent performance killer for gaming PCs, laptops, and PS5 consoles. When stock thermal interface materials degrade or dry out over time, heat builds up rapidly on your CPU or GPU die. This causes aggressive fan noise, unpredictable frame drops, and long-term hardware wear during intense workloads.

Applying this high-conductivity 12.4 W/mK thermal grease solves heat transfer bottlenecks immediately. By micro-filling microscopic imperfections between the processor heat spreader and the heatsink base, it ensures direct heat dissipation, keeping your system cool, whisper-quiet, and running at peak performance.

Who Is It For?

Ideal for PC builders, console modders, and budget-conscious gamers looking to repaste their gaming desktop, laptop, or PS5 without paying high name-brand premiums. It is also perfect for computer repair technicians who require cost-effective bulk thermal compound (up to 30g) for multiple routine system maintenance jobs.

Key Features

  • 12.4 W/mK Thermal Conductivity
    Delivers rapid heat transfer away from high-TDP processor dies to reduce system operating temperatures
  • Multiple Gram Size Options (1g to 30g)
    Allows users to choose exact quantities for a single repaste or high-volume bench repair work
  • Electrically Non-Conductive Formula
    Eliminates the risk of short circuits or motherboard damage if excess paste spreads onto surrounding circuitry
  • Low Thermal Resistance Texture
    Fills micro-gaps smoothly under heatsink pressure without leaving air pockets
  • Long-Lasting Viscosity Stability
    Resists drying out and pump-out effects over long-term high-temperature operations

Pros & Cons

Pros

  • Outstanding 12.4 W/mK thermal performance for under $3
  • Safe electrically non-conductive composition
  • Versatile compatibility with CPUs, GPUs, and PS5 processors
  • Available in economical bulk sizes up to 30g

Cons

  • Application spatula included in package is basic
  • Thicker viscosity requires even pressure during heatsink mounting

FAQ
