Gelid GP-Ultimate (Silicone-Based Pad/Non-Conductive/15 W/mK) Review
GP-Ultimate is Gelid's top-tier silicone pad, and at 15 W/mK it's genuinely competitive, that's higher than most of the pastes in our catalog, paste and pad numbers aren't directly comparable, but it tells you Gelid isn't just phoning in a budget filler here.

Thermal Performance and Conductivity
15 W/mK puts GP-Ultimate ahead of Gelid's own GP-Extreme (12 W/mK) and most silicone competitors in this catalog, trailing only Fujipoly's Ultra Extreme XR-m at 17.
Compound Type and Composition
A silicone-based pad, safe, non-conductive, and available in enough thickness options (0.5mm to 1.5mm, plus larger sheet sizes) to actually fit the gap you're trying to fill rather than forcing a compromise.
Application and Consistency
Cut to size, place, done, no mess, no cure time. The main decision you'll actually make is picking the right thickness for your gap, not how to apply it.
Electrical Safety
Fully non-conductive. No precautions needed beyond normal handling.
Longevity and Pump-Out Resistance
Pads don't pump out or dry the way paste does. GP-Ultimate is a long-term install, not a wear item you're tracking a reapplication date for.
Comparison to Sibling Products
Against Gelid's own GP-Extreme, covered elsewhere on this site, GP-Ultimate wins on conductivity for a modest step up in price, worth it if you're filling a gap on a component that actually runs hot. Against Fujipoly's Ultra Extreme XR-m, Fujipoly edges it out on paper, though availability and thickness options may decide it in practice.
Who This Pad Is Actually For
Winner for: GPU VRAM and VRM cooling where you want real conductivity without going conductive-material territory.
GPU memory and VRM gap-filling.
Laptop heatsink contact where a pad fits better than paste.
Not for: Primary CPU die contact, that's still paste or a dedicated pad like the carbon/graphene options territory.
Not for: Builds where budget matters more than the extra few W/mK over GP-Extreme.
