Alphacool Eisschicht Thermal Pad 11W/mK vs Coollaboratory Liquid Extreme: Comparison
Alphacool Eisschicht Thermal Pad 11W/mK vs Coollaboratory Liquid Extreme thermal conductivity compared
Expect a near tie. The closest thing to a difference is thermal conductivity, Alphacool Eisschicht Thermal Pad 11W/mK 11 W/mK against Coollaboratory Liquid Extreme 41 W/mK. Paste segment is not the same on both, Pad on the Alphacool Eisschicht Thermal Pad 11W/mK versus Liquid Metal on the Coollaboratory Liquid Extreme.
Alphacool Eisschicht Thermal Pad 11W/mK vs Coollaboratory Liquid Extreme: which one fits your build
it is not the pick for large single-surface coverage, given this sheet's compact 95x32mm footprint. The same goes for VRM, VRAM, and other board-level components needing a conforming, paste-like pad rather than a stiff sheet. It is not the one for buyers wanting Alphacool's highest-conductivity Eisschicht variant, which is sold at 14 and 17 W/mK in other sizes. The Coollaboratory Liquid Extreme is the one to take for delidded CPUs with nickel-plated copper heatspreaders and coolers and high-end GPU direct-die cooling with careful masking, though it is not built for any aluminum cooler, heatspreader or cold plate and first-time builders or anyone uncomfortable masking components. It also earns its place with experienced builders wanting a more spreadable liquid metal than Liquid Pro. Avoid it for laptops or GPUs where a spill could reach exposed components unnoticed. Our rating of the Alphacool Eisschicht Thermal Pad 11W/mK (6.6/10): A cuttable pad that clings closely to components and resists drying out, according to Alphacool, though independent testing is limited. Our rating of the Coollaboratory Liquid Extreme (7.6/10): A straightforward 100% metal TIM from an established liquid-metal specialist, performance-focused rather than beginner-friendly.
