# Simulation Quiz 1

### Laptop Cooling With a Heat Sink

Laptop overheating can be a common issue while working on applications requiring high-end computation. To minimize or avoid overheating, engineers must design the laptop with proper heat dissipation. To achieve this goal, there are often cooling fans and heat sinks installed within laptops. For this case, a simplified laptop geometry is analyzed under steady state conditions to study the benefit of using a heat sink.
