Which should you buy, Alphacool Eisschicht Thermal Pad 11W/mK or Phobya Thermal Pad Ultra 5W/mK?
it is the wrong buy for large single-surface coverage, given this sheet's compact 95x32mm footprint. It is equally the pick 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. it is not the pick for buyers wanting Phobya's higher-conductivity Thermal Pad XT line instead. The same goes for VRAM, VRM, and mainboard chipset cooling needing a compressible pad to bridge height differences up to 4mm. Avoid it for CPU IHS-to-cooler contact where a conventional paste offers thinner bond lines. 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 Phobya Thermal Pad Ultra 5W/mK (5.8/10): A small single-piece pad with modest conductivity, a niche fit for specific gap sizes.
What Alphacool Eisschicht Thermal Pad 11W/mK and Phobya Thermal Pad Ultra 5W/mK have in common
Everything else lines up. Pump-out resistance and paste segment read the same on both, so those are not worth weighing.
