Alphacool Apex Thermal Pad Soft 18W/mK vs Bergquist (Henkel) Bergquist Gap Pad TGP HC3000: Comparison
Alphacool Apex Thermal Pad Soft 18W/mK vs Bergquist (Henkel) Bergquist Gap Pad TGP: the thermal conductivity difference
Expect a near tie. The closest thing to a difference is thermal conductivity, Alphacool Apex Thermal Pad Soft 18W/mK 17.8 W/mK against Bergquist (Henkel) Bergquist Gap Pad TGP 3.0 W/mK. They differ on viscosity too, 0 Pa-s on the Alphacool Apex Thermal Pad Soft 18W/mK versus Soft, high-compliance silicone sheet on the Bergquist (Henkel) Bergquist Gap Pad TGP. They differ on recommended use too, High-end CPU/GPU on the Alphacool Apex Thermal Pad Soft 18W/mK versus Mainstream CPU/GPU and general electronics gap filling on the Bergquist (Henkel) Bergquist Gap Pad TGP. There is a split on conductivity source as well, https://shop.alphacool.com/en/shop/thermal-conductant/thermal-pads/waem-alphacool-apex-thermal-pad-soft-18w/mk-120x20x1mm on the Alphacool Apex Thermal Pad Soft 18W/mK versus https://next.henkel-adhesives.com/us/en/products/thermal-management-materials/central-pdp.html/bergquist-gap-pad-tgp-hc3000/112215IB.html on the Bergquist (Henkel) Bergquist Gap Pad TGP.
Who each one is for
Take the Alphacool Apex Thermal Pad Soft 18W/mK for high-end CPU/GPU, VRM/MOSFET, and memory-module cooling wanting the highest independently-measured W/mK figure among this catalog's pads. The same goes for builds needing a documented electrical safety spec sheet (volume resistance, dielectric breakdown) rather than a generic non-conductive claim. Avoid it for buyers who specifically want Eisschicht's softer, more paste-like conforming fit for delicate uneven surfaces. The Bergquist (Henkel) Bergquist Gap Pad TGP is the one to take for 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 Apex Thermal Pad Soft 18W/mK (6.8/10): A soft, high-conductivity pad aimed at high-end builds, though it lacks the independent review base of the paste side of Alphacool's lineup. Our rating of the Bergquist (Henkel) Bergquist Gap Pad TGP (6.3/10): an industrial gap pad from Henkel's Bergquist line, reliable for OEM applications.
Where the two are identical
Where they agree, they agree completely, compound type, electrical conductivity and paste segment included, so the decision does not turn on any of those.
