Alphacool Apex 2 Thermal Paste vs Bergquist (Henkel) Bergquist Gap Pad 2500S20: Comparison
What is the difference between Alphacool Apex 2 Thermal Paste and Bergquist (Henkel) Bergquist Gap Pad?
There is no decisive spec gap here. Thermal conductivity splits them by a margin most buyers will never feel, Alphacool Apex 2 Thermal Paste 6.7 W/mK against Bergquist (Henkel) Bergquist Gap Pad 2.4 W/mK. They differ on viscosity too, 130 Pa-s on the Alphacool Apex 2 Thermal Paste versus Reinforced soft silicone sheet on the Bergquist (Henkel) Bergquist Gap Pad. They differ on recommended use too, High-end CPU/GPU on the Alphacool Apex 2 Thermal Paste 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/detail/index/sArticle/22025 on the Alphacool Apex 2 Thermal Paste 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. There is a split on paste segment as well, Standard Paste on the Alphacool Apex 2 Thermal Paste versus Pad on the Bergquist (Henkel) Bergquist Gap Pad.
Who each one is for
it is not the pick for buyers who specifically want liquid-metal-level conductivity. It also earns its place with high-end CPU and GPU builds, overclocking rigs, workstations and servers wanting Alphacool's current-generation paste. It is the wrong buy for anyone needing a confirmed silicone/carbon base disclosure, which Alphacool has not published for this formula. The Bergquist (Henkel) Bergquist Gap Pad suits general electronics gap filling and mainstream CPU/GPU, though it is the wrong buy for high-power dies needing >5 W/mK. Our rating of the Alphacool Apex 2 Thermal Paste (6.7/10): A high-end Alphacool paste with a solid published conductivity figure, though independent review coverage is thinner than bigger paste-specialist brands. Our rating of the Bergquist (Henkel) Bergquist Gap Pad (6/10): A lower-conductivity industrial gap pad, suited to less demanding OEM cooling needs.
Where the two are identical
The common ground is wider than the gap: electrical conductivity are identical here.
