Alphacool Eisschicht Thermal Pad 11W/mK Review

The Alphacool Eisschicht is Alphacool's higher-performance thermal pad line, rated 11.0 W/mK in this size and sold as a paste-like alternative to standard silicone thermal pads.

Alphacool officially rates this Eisschicht pad at 11.0 W/mK with a working range of -40 to +150C, and the company markets its main advantage as fit rather than raw conductivity: the material clings to components more like a paste than a typical stiff pad, reducing the contact pressure a cooler puts on delicate VRM or VRAM chips, and it's said to dry out slower than standard pads so it keeps performing over a longer service life. Alphacool also sells the Eisschicht line in higher-conductivity 14W/mK and 17W/mK variants and different sheet sizes, with this 95x32x0.5mm sheet being one of the smaller options in the range. Against Alphacool's own Apex Thermal Pad Soft also in this catalog, the Eisschicht line trades some raw conductivity for a softer, paste-like fit against uneven or delicate surfaces.

Thermal Performance and Conductivity

Alphacool officially rates this Eisschicht sheet at 11.0 W/mK, one tier below the company's higher-output Eisschicht variants (14 and 17 W/mK) sold in other sizes.

Composition

Alphacool markets the Eisschicht material as behaving similarly to a thermal paste in how it conforms to a component's surface, rather than as a stiff standard silicone pad.

Application and Consistency

The pad can be cut to size with scissors as long as the protective foil stays on during cutting, and it ships as a 95x32x0.5mm sheet.

Longevity and Pump-Out Resistance

Alphacool states the Eisschicht material dries out more slowly than standard thermal pads, extending usable service life before performance drops.

Comparison to Alternatives

Against Alphacool's own Apex Thermal Pad Soft also in this catalog, the Eisschicht trades some raw W/mK conductivity for a softer, paste-like fit against uneven surfaces such as VRM or VRAM modules.

Our verdict

Reviewed by Burooj Alam. Rated by us, not by users.

Expert rating6.6 / 10

A cuttable pad that clings closely to components and resists drying out, according to Alphacool, though independent testing is limited.

Best for

VRM, VRAM, and other board-level components needing a conforming, paste-like pad rather than a stiff sheet
Builders wanting a thermal pad with a wide -40 to 150C rated range

Not for

Buyers wanting Alphacool's highest-conductivity Eisschicht variant, which is sold at 14 and 17 W/mK in other sizes
Large single-surface coverage, given this sheet's compact 95x32mm footprint
