White 4 g syringe of grey thermal paste with black cap

Thermal Hero

Thermal Hero NEO thermal paste 4 g

SKU CH-J0FC-Z08TA

Silicone-based thermal paste with high conductivity and low viscosity for CPUs, GPUs and consoles

  • High cooling performance from high thermal conductivity and low thermal resistance
  • Safe for all components with non-conductive, non-corrosive, non-toxic formula
  • Easy application thanks to low viscosity and high flow properties
  • Stable long-term operation without drying, hardening or separating
  • Suitable for CPUs, GPUs, consoles and ICs across office to overclocking use

What this product is and who it is for

Thermal Hero NEO is a silicone-based thermal paste supplied in a 4 g syringe. It is intended for PC builders, overclockers and console owners who need reliable heat transfer between a processor or graphics chip and its cooler. The compound is non-conductive, non-toxic and compliant with RoHS and REACH, making it safe for any skill level. It suits both new builds and maintenance on CPUs, GPUs and gaming consoles.

How it fits into a build

The paste spreads easily thanks to low viscosity and high flow, so it covers the die evenly without requiring heavy mounting pressure. It does not migrate after application and will not corrode or oxidise metal surfaces over time. Because it is electrically insulating, there is no risk of short circuits if excess material contacts surrounding components. A single 4 g portion covers multiple installations on desktop processors, laptop chips or console APUs.

Behaviour under sustained load

Thermal Hero NEO maintains stable thermal resistance and conductivity during prolonged high-temperature operation typical of overclocking or extended gaming sessions. The formulation resists drying out, hardening or separating into its base components, so cooling performance remains consistent over years of use. Low contact pressure is sufficient for effective heat dissipation, reducing mechanical stress on delicate dies during long-term thermal cycling.

Questions about this item

How long does the 4 g syringe last before the paste dries out or hardens?

The compound does not dry out, harden or separate into its components, so the full 4 g remains usable for many applications over years.

Does the paste become electrically conductive or corrode metal surfaces when the system runs hot all day?

It is non-electrically-conductive, non-toxic and will not corrode or oxidise any metal it contacts, even at sustained high temperatures.

What tools or accessories are needed to apply this paste to a CPU or GPU?

Only the syringe and a clean lint-free cloth or spreader are required; the low-viscosity formula spreads easily under light pressure without additional equipment.
