Answer:
the engineer should build a water-cooled heatsink
Explanation:
If a regular full metal heatsink is not working due to the computer chip producing too much heat then the engineer should build a water-cooled heatsink. These are usually metal heatsinks that are filled with water. Since water has a great heat capacity it is able to retain heat very efficiently without actually warming up the water (to a certain degree). Therefore, a water heat sink is able to take the heat produced from the CPU and cool down the CPU by dissipating that heat in the water.
