Alphacool Apex 2 Thermal Paste vs Deepcool G40: Comparison
What is the difference between Alphacool Apex 2 Thermal Paste and Deepcool G40?
Start with thermal conductivity, because it is the widest measured gap between them: Alphacool Apex 2 Thermal Paste 6.7 W/mK against Deepcool G40 5.2 W/mK, 22% in favour of Alphacool Apex 2 Thermal Paste. 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://www.deepcool.com/products/Accessories/ThermalPaste/2021/11408.shtml on the Deepcool G40.
Which should you buy, Alphacool Apex 2 Thermal Paste or Deepcool G40?
it is the wrong buy 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. Avoid it for anyone needing a confirmed silicone/carbon base disclosure, which Alphacool has not published for this formula. The Deepcool G40 suits multiple installs, dual-GPU setups, or repeat reapplications from one tube and overclockers who want the G-series conductivity in a larger package, though it is not the pick for buyers who need DS7/DS9-tier top-end conductivity. It is the wrong buy for single-install buyers who don't need 4g of paste (G15's 1.5g is cheaper and sufficient). 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 Deepcool G40 (5.8/10): an overclocking-focused entry paste from Deepcool, adequate but unremarkable.
What Alphacool Apex 2 Thermal Paste and Deepcool G40 have in common
Everything else lines up. Electrical conductivity, density and paste segment read the same on both, so those are not worth weighing.
