White 4g syringe of grey thermal paste with black cap

Thermal Hero

Thermal Hero ULTRA Series Thermal Paste 4g

SKU CH-BF0N-BJ85H

Silicone-based thermal paste with ultra-high conductivity and low resistance for extreme overclocking and gaming on CPUs, GPUs and consoles in a 4 g syringe

  • Ultra-high thermal conductivity for extreme cooling performance
  • Non-electrically conductive, non-toxic formula protects components
  • Low viscosity paste spreads easily on any surface
  • Engineered for overclocking and gaming workloads
  • Stable at sustained high temperatures without drying out

Ultra-High Conductivity Paste

Thermal Hero ULTRA Series is a silicone-based thermal compound with ultra-high thermal conductivity and very low thermal resistance. The 4 g syringe delivers reliable heat transfer for CPUs, GPUs and console processors. It is non-electrically conductive, non-toxic and RoHS/REACH compliant. The formula resists drying, hardening or separation over time.

Sustained High-Temperature Stability

The paste maintains low thermal resistance during prolonged heavy loads and clock-rate peaks. It reacts flexibly to rapid temperature changes, dissipating heat quickly and consistently as demand fluctuates. Long-term stability is preserved even at the highest operating temperatures. No degradation, corrosion or oxidation occurs during extended use.

Compatibility And Application Check

Verify the component surface is clean and free of old compound before applying. The low-viscosity formula spreads easily with any standard method on CPU, GPU, IC or console chips. Ensure the 4 g volume covers your intended application count. The product carries a five-year warranty only while the syringe remains unopened.

Questions about this item

How does the ULTRA paste behave after months of daily high-load gaming sessions?

The silicone-based compound does not dry out, harden or separate, so thermal resistance stays low even after prolonged periods at sustained high CPU temperatures.

What surfaces or tools do I need before applying this paste?

The low-viscosity formula spreads easily on any CPU, GPU or console die with a spatula, card or pea-dot method — no special primers or cleaning solvents are required beyond standard isopropyl alcohol.

Is the ULTRA paste safe to use on older consoles like a PlayStation 3 or original Xbox?

Yes, it is non-electrically-conductive, non-corrosive and RoHS/REACH compliant, so it poses no risk to legacy processor packages or surrounding components.
