Alphacool Eisschicht Thermal Pad 11W/mK vs Bergquist (Henkel) Bergquist Gap Pad 2500S20: Comparison
Alphacool Eisschicht Thermal Pad 11W/mK vs Bergquist (Henkel) Bergquist Gap Pad thermal conductivity compared
These two are close on paper, and thermal conductivity is the only measure that separates them at all: Alphacool Eisschicht Thermal Pad 11W/mK 11 W/mK against Bergquist (Henkel) Bergquist Gap Pad 2.4 W/mK. They differ on viscosity too, Manufacturer describes it as clinging closely to components similarly... on the Alphacool Eisschicht Thermal Pad 11W/mK versus Reinforced soft silicone sheet on the Bergquist (Henkel) Bergquist Gap Pad. Recommended use is not the same on both, Mainstream CPU/GPU; Alphacool also markets it for VRM, VRAM,... on the Alphacool Eisschicht Thermal Pad 11W/mK versus Mainstream CPU/GPU and general electronics gap filling on the Bergquist (Henkel) Bergquist Gap Pad. There is a split on conductivity source as well, https://shop.alphacool.com/en/shop/thermal-conductant/thermal-pads/wagz-alphacool-ice-layer-thermal-pad-11w/mk-100x100x1mm-eol on the Alphacool Eisschicht Thermal Pad 11W/mK versus https://next.henkel-adhesives.com/us/en/products/thermal-management-materials/central-pdp.html/bergquist-gap-pad-tgp-2400/112643IB.html on the Bergquist (Henkel) Bergquist Gap Pad.
Who each one is for
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 the wrong buy for buyers wanting Alphacool's highest-conductivity Eisschicht variant, which is sold at 14 and 17 W/mK in other sizes. The Bergquist (Henkel) Bergquist Gap Pad suits general electronics gap filling and mainstream CPU/GPU, though it is not built for high-power dies needing >5 W/mK. 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 Bergquist (Henkel) Bergquist Gap Pad (6/10): A lower-conductivity industrial gap pad, suited to less demanding OEM cooling needs.
What Alphacool Eisschicht Thermal Pad 11W/mK and Bergquist (Henkel) Bergquist Gap Pad have in common
The common ground is wider than the gap: paste segment are identical here.
