Abstract: A variable fin stack for cooling components in a chassis of a portable information handling system. The variable fin stack comprises a first array of fins coupled to a first conduit and a second array of fins coupled to a second conduit. When the chassis is in a compact configuration for use in a mobile mode, fins in the second array of fins are positioned between fins in the first array of fins and the chassis maintains a form factor. When the chassis is in an expanded configuration for use in a workstation mode, the second array of fins is withdrawn from the first array of fins and the increased surface area provides increased cooling of components operating at higher power levels.
