Effects of Dust Accumulation on Servers
Computing servers house a wide array of electronic components designed to operate within a specific thermal range. Operating these components outside of their specified thermal range, even for a relatively short amount of time, could result in system instability and premature hardware failure.
To prevent the servers’ electronic components from operating outside of their specified thermal limit, active cooling is traditionally used to keep their temperature down. Pulse width modulated (PWM) axial fans, embedded thermal sensors and thermal profiles work together in a closed loop to cool down the electronic components by controlling the amount of airflow flowing through the server’s chassis.
However increasing the airflow accelerates dust accumulation inside of the server’s chassis and around the electronic components. Dust accumulation on and around electronics components is bad news and will eventually lead to hardware failure.
- Dry dust is heavier than air and tends to form insulating blankets on top of electronic components. With no effective air contact, these insulated components can no longer be cooled and easily overheat enough to operate outside of their specified thermal range.
- Moist (or wet) dust is a partial conductor and is capable of initiating unwanted electrical shorts and high voltage discharges that destroy electronic components instantaneously.
The Advatronix® Cirrus™ 1200 is designed to keep the dust where it belongs, outside of its chassis. A permanent, reusable, high precision, synthetic mesh filter dramatically restricts dust from entering the server and maintains a clean operation at all time. Frequency optimized, extremely quiet rear-mounted axial fans use large blades and operate at moderate RPMs to deliver best in class static pressure and air flow to noise ratio, allowing the server to operate in a clean, cool & quiet fashion.
