LiquidcoolingLiquid cooling systems are used when air cooling is not sufficient. Liquid-based cooling systems are composed of tubes, cooling plates, a reservoir, and a radiator. Cooling plates have tubes connected to them and are attached to components. Liquid coolant is then circulated through the system, cooling it. Because liquid cooling can dissipate heat much faster than air cooling, it is primarily used for high-end gaming computers and high-performance systems.Issues related to insufficient cooling are sometimes difficult to identify. They usually manifest as random errors or system lockups. One tool that can be used to troubleshoot cooling problems is freeze spray. If a system is starting to fail due to overheating, spraying it with freeze spray reduces the temperature and could restore it to normal functionality. If the problem goes away after spraying a suspected component, implement additional cooling solutions for that component.Cooling System RecommendationsBecause proper airflow is necessary to keep components cool, consider the following recommendations to ensure optimal system cooling:Keep the case free of dust and debris. Excess dust can restrict airflow and prevent proper heat transfer.Reduce the number of airflow obstructions.oEmploy proper cable management (e.g., bundle cables together and secure unused cables to the case).oSpace out multiple hard disk drives instead of stacking them next to each other.oDo not use an excess number of expansion cards.Maintain appropriate ambient temperatures. Optimal ambient temperatures are between 60 and 80 degrees Fahrenheit. For server rooms, the ambient temperature might be as low as 45 degrees.Ensure proper ventilation.oKeep air intakes and exhausts free from obstructions.oLeave space between the computer and any walls or desks.Preserve negative pressure inside the case by keeping all covers and shields installed (e.g., unused expansion cards, I/O shield, front drive bays).
