Liquid coolers can be more effective at cooling high-TDP CPUs, making them a good option for high-performance SFF builds. However, liquid coolers require more space than air coolers, so make sure your case can accommodate a radiator. All-in-one (AIO) liquid coolers are a popular choice for SFF builds, as they are self-contained and require minimal maintenance. Custom liquid cooling loops offer the best cooling performance but are more complex and expensive to set up.

Case fans are essential for improving airflow within your SFF case. Case fans help to draw cool air into the case and exhaust hot air, preventing heat buildup. When choosing case fans, consider the size, airflow, and noise level. Larger fans typically move more air at lower RPMs, resulting in quieter operation. Fans with higher airflow ratings are better at cooling, but they may also be louder. Strategically placing case fans can significantly improve cooling performance. Typically, you'll want to install intake fans at the front and bottom of the case to draw cool air in, and exhaust fans at the rear and top of the case to exhaust hot air. Experiment with different fan configurations to find the optimal airflow pattern for your case. Optimizing airflow within your SFF case is crucial for efficient cooling. Cable management plays a significant role in airflow. Messy cables can obstruct airflow and trap heat. Take the time to route cables neatly and keep them out of the way of fans and heatsinks. Using cable ties and zip ties can help to organize cables and improve airflow. Consider the placement of your components within the case. Position components that generate a lot of heat, such as the CPU and GPU, in areas where they will receive adequate airflow. If your case has limited airflow, you may need to consider undervolting your CPU and GPU. Undervolting reduces the voltage supplied to the components, which can lower their temperature without significantly impacting performance. By carefully choosing your cooling solutions and optimizing airflow, you can ensure that your SFF PC stays cool and performs at its best.

Cable Management: Taming the Spaghetti Monster

Cable management is an often-overlooked aspect of PC building, but it's especially crucial in SFF builds due to the limited space.
