Smart technologies are the scientific knowledge application that develops into computer technology. Central Processing Unit (CPU) is a computer hardware that carries out the computer program instructions. The CPU technology development is very fast with the impression of smaller dimensions yet maintain its performance and efficiency, this results in a heat flux or overheating that should be reduced and even removed from the CPU system to maintain the CPU performance and life because the overheating could potentially damage and slow down the computer work. To solve the CPU heat flux problem, we use heat pipes as the cooling system, because of its ability to transfer heat and contribute to the high outlet temperature in the condenser. The cascade heat pipe design is made by combining two heat pipes into one. The design is expected to be able to reduce the processor temperature by 2.74°C at the idle condition, 1.48°C at maximum conditions, and condenser section by 14.94°C at the idle condition, and 21.12°C at maximum condition. Cascade heat pipe with double condenser reduce processor temperature by 3.89°C at the idle condition, 4.24°C at the maximum condition, condenser section by 17.12°C at the idle condition and 24.16°C at maximum condition lower than the non-cascade cooling system.
