White 10g syringe of thermal paste with black cap

Thermal Hero

Thermal Hero ULTRA Series Thermal Paste 10g

SKU CH-AZVM-SF3SC

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

  • Ultra-high thermal conductivity keeps overclocked CPUs and GPUs cool
  • Low thermal resistance handles sustained high clock-rate peaks
  • Non-conductive, non-toxic formula protects hardware from shorts or corrosion
  • Stable silicone compound resists drying, hardening or separation over time
  • Low-viscosity paste spreads easily on any CPU, GPU or console chip

High-conductivity paste for overclocking

Thermal Hero ULTRA is a silicone-based compound rated at 10 g. It targets enthusiasts who push CPU and GPU clocks beyond stock limits and need consistent heat transfer during sustained loads. The paste remains stable at high temperatures without drying, hardening or separating.

Non-conductive formula limits electrical risk

The material is not electrically conductive, so accidental contact with surrounding components will not cause shorts. It contains no toxic substances and complies with ROHS and REACH regulations. Corrosion and oxidation are absent, making it safe for long-term use on copper, aluminium or nickel-plated surfaces.

Check mounting pressure and surface flatness

Verify that your cooler provides even pressure across the die or heat-spreader; uneven seating can trap air pockets despite the paste’s low viscosity. Ensure the mating surfaces are clean and free of old compound residue before application. The product is unsuitable for sub-ambient cooling methods that require specialised pastes.

Questions about this item

Should I pick the 10g tube or a larger size for my build?

The product is supplied as a single 10g tube, which is enough for several CPU or GPU applications.

How does the ultra-high thermal conductivity translate to real-world temperatures?

The paste achieves very low thermal resistance, allowing efficient heat dissipation at sustained high CPU temperatures and clock-rate peaks.

What interface or standard does this paste follow, and what does that limit?

It is a silicone-based compound with no electrical conductivity, so it is safe for all CPU, GPU and console surfaces without risk of short circuits.
