High-performance thermal compound with extreme conductivity for CPUs, GPUs and consoles
Thermal Hero Quantum is a silicone-based thermal paste engineered for enthusiasts who push CPUs and GPUs to their limits. The 10g syringe targets gamers, overclockers and high-end server operators who need reliable heat transfer under continuous heavy loads. It is also compatible with PlayStation and Xbox consoles for internal maintenance.
Unlike standard pastes that degrade, this compound maintains low thermal resistance and high conductivity even at elevated ambient and die temperatures over long sessions. The formulation resists hardening, dissolution and oxidation, so thermal impedance stays stable during extended rendering, compute or gaming marathons. Non-electrically conductive properties eliminate short-circuit risk if excess material bridges nearby components.
Before ordering, confirm your cooler’s mounting mechanism provides even pressure across the integrated heat spreader, as uneven contact negates the paste’s low-resistance advantage. Ensure both CPU and GPU surfaces are clean, flat and free of old compound residue to achieve the intended bond line thickness. The 10g volume covers multiple applications, but very large server dies or direct-die mounting may require more material per seat.

No published specifications for this item yet.
Yes, the paste is non-electrically conductive, non-toxic and does not corrode or oxidise, so it remains safe for long-term use under heavy workloads.
You need the CPU or GPU you are cooling, a compatible heatsink or water block, isopropyl alcohol and a lint-free cloth for cleaning the old compound, and a spreading tool or the supplied applicator if one is included.
The compound is designed for sustained high temperatures and does not dry out, harden or separate, so it maintains consistent performance on legacy CPUs and GPUs that run hot.
