The core is 50 mm thick against the factory 25 mm, giving 2.07× the factory core volume and a far longer heat-exchange path for the coolant.

Those figures are geometric. Actual cooling performance is also shaped by the core structure, fin density, material conductivity and the graphene coating, so the real-world margin is wider than the volume number alone suggests.
