In summary, forced air cooling is an efficient way of implementing thermal management for an enclosed PCB and with semiconductors and PCBs becoming ever more complex and dense, component failure is often linked to insufficient cooling that causes overheating. If a fan is chosen for cooling, then selection of the right fan should not be taken lightly. Determining a system’s thermal profile, calculating needed airflow and performance, and understanding fan types and features are all important things to consider. Thankfully Same Sky offers DC fans and blowers with various features and performance ratings to meet a range of thermal requirements, which can mean the difference between premature failure and an efficiently operating system.
