Cooling System Compatibility

Correct Answer: Cooler height

When installing a CPU air cooler in a compact microATX case with limited clearance, the most important factor to consider is the cooler height. The height determines whether the cooler will fit within the available space inside the case. If the cooler is too tall, it may not clear the case's side panel or interfere with other components. The length and thickness of the cooler are less critical as long as there is sufficient room around the CPU socket. Cable length is not a significant factor for air coolers since they typically use standard fan headers on the motherboard.

Correct Answer: Technical specifications of the cooler

When building a gaming PC, it is crucial to ensure that the selected CPU cooler is compatible with the motherboard's socket. The technical specifications of the cooler will provide information about the socket types it supports. By comparing this information with the motherboard's socket type, you can determine if the cooler will fit properly. Cooler reviews, color, and brand are not reliable indicators of socket compatibility, as they do not directly address the technical aspects required for a proper fit between the cooler and the motherboard.

Correct Answer: Thermal paste application

Improper thermal paste application can cause insufficient heat transfer from the CPU to the cooler, leading to higher than expected temperatures. Always check first that the paste is properly applied.
