Effective cooling power for shrinking enclosures is provided by the Biscuit brushless dc blower. The unit is said to offer high-pressure airflow within tight spaces, such as in RAID drives, power supplies, and small 1U rack-mount applications. Measuring 4.74" square x 1.22" deep, the blower weighs just 10 oz. and delivers airflow from 18 to 28 cfm with minimal audible noise. Units are available with the firm’s ThermaPro-V technology, which automatically adjusts airflow based on current temperature needs, minimizing power consumption and noise.
