Computer smoking
The workings of a computer consist of a power supply, mainboard, storage media and a central processing unit (CPU). Inside the CPU of a computer, every input and task of the computer is calculated and executed, these processed workloads create excess heat and engage a mounted thermal system to keep it from overheating. Airflow through a cooling block on the CPU is used to dissipate the excess heat and relieve the system. This system 'breathes' a cigarette, leaving residue throughout the system and inhibiting its own performance.
