Gelid GC-Supreme (Silicone-Based/Non-Conductive/Premium Mid-Tier Compound) Review
Gelid GC-Supreme is a silicone-based thermal paste rated above 4.5 W/mK, sitting below Gelid's own GC-Extreme in the lineup as a mid-tier compound for mainstream CPU and GPU builds.
It's the paste Gelid sells between GC1 and GC-Extreme, a nano-scale silicone compound in a 7g tube with a bundled applicator, aimed at people who want an easy, no-mess reapplication rather than chasing the last degree of delta-T.
Thermal Performance and Conductivity
Gelid only publishes GC-Supreme's conductivity as ">4.5 W/mK", well below GC-Extreme's 8.5 W/mK. It's a mid-pack number, fine for a mainstream CPU or GPU but not what we'd reach for on a high-end overclock.
Compound Type and Composition
Silicone-based and non-electrically conductive, with a nano-scale molecular structure Gelid markets as easy to spread and easy to clean off later.
Application and Consistency
At 250,000 centipoise it's a thick paste. Gelid ships a dedicated applicator in the 7g tube, so you're not eyeballing a pea-sized dot with your finger.
Safety and Handling
Gelid markets it as non-flammable, non-toxic, and safe for incidental skin contact, resistant to oxidation and corrosion over time.
Comparison to Sibling Products
Against GC-Extreme, already in our catalog at 8.5 W/mK, GC-Supreme is the budget step-down, lower conductivity, lower price. Against GC-Pro (7 W/mK), GC-Supreme is actually the weaker performer on paper despite the more premium-sounding name, so don't assume the naming maps directly to performance tier.

Expert Review
Reviewed by Burooj Alam. Rated by us, not by users.
Best for
- Mainstream CPU and GPU coolers where an easy-to-apply, non-mess paste matters more than chasing the lowest delta-T.
- Builders who want a bundled applicator instead of spreading paste with a finger or card.
Not for
- High-end or overclocked builds where GC-Extreme's 8.5 W/mK or a higher-conductivity paste would make a bigger difference.
