Answer :
Final answer:
To keep a computer cool, it is important to ensure that the cooling fans are functioning correctly, regularly vacuum dust from the system, and maintain a cool environment.
Explanation:
All of these options can be helpful in keeping a computer cool, but the most helpful one would be to verify that cooling fans are not circulating air in the wrong directions. Cooling fans are designed to circulate cool air around the computer components, so if they are not functioning properly, the computer can overheat. Vacuuming dust from the system regularly is also important as dust can accumulate and block airflow, causing the computer to heat up. Air conditioners can help in keeping the environment cool, but they are not specifically targeted towards cooling the computer itself.
