What are some methods of cooling a computer’s CPU and HDDs?

  There are several methods of cooling a computer's CPU and hard disk drives (HDDs), including: Air cooling: This method uses fans to circulate air over the heat sink, which is attached to the CPU, to dissipate heat. Additional case fans can also be used to cool other components such as the HDDs. Liquid cooling: This method uses a liquid, such as water or a specialized coolant, to transfer heat away from the CPU and other components. Liquid cooling systems can be more effective than air cooling systems, but they are also more complex and require more maintenance. Passive cooling: This method uses heat sinks, which are large metal surfaces that dissipate heat, without the use of fans. Passive cooling is generally less effective than active cooling methods, but it is also quieter and requires less maintenance. Phase-change cooling: This method uses a refrigerant to absorb heat from the CPU and transfer it to a cooling unit that vaporizes the refrigerant and expels the heat out of the...
