Summary of above video:

• Create a thermal physics region of material copper for the chips and CPU.
• Add an inlet with velocity 57.609 in/s.
• Add an outlet with pressure 0 Pa.
• Add a solid heat generation term to the chips and CPU.
• Add an insulated boundary to the bottom of the chips and CPU.
• Add a wall.
• Change convergence criteria to 1e-3.
  • This enables the solution to converge quickly and is sufficient for our tutorial.  AIM uses a smaller default value to increase accuracy.
