Gelid GC-5 Extreme Thermal Paste (Synthetic/Non-Conductive/Wide-Temp-Range Compound) Review
Gelid GC-5 Extreme Thermal Paste is a synthetic, non-conductive compound rated for -40C to 150C operation, sold in a single 3.5g tube with a precision applicator.
Like GC-4, Gelid doesn't publish a conductivity figure for GC-5, so what you're actually buying here is a wider operating range (-40C vs GC-4's -30C) and a higher published density and viscosity, not a documented performance jump.
Thermal Performance and Conductivity
No W/mK figure is published by Gelid for GC-5. We're leaving that field blank rather than estimating it.
Compound Type and Composition
A synthetic thermal compound, non-electrically conductive, described by Gelid as extremely durable and non-curing.
Application and Consistency
At roughly 330,000 cps it's thicker than GC-4's ~100,000 cP, closer to GC-Supreme's 250,000 cP range, and ships with a precision applicator.
Operating Range
Rated from -40C to 150C, the widest published range of Gelid's GC-series pastes in our catalog.
Comparison to Sibling Products
Sits alongside GC-4 as Gelid's other "extreme" paste without a published conductivity number, the practical difference between the two is operating range and viscosity, not documented thermal performance.
