During an overnight audit, a monitoring platform logs repeated CPU temperature alerts on a 2-U application server. When the systems administrator examines the front bezel, a thick layer of dust is visible on the intake vents and heat-sink fins, and the fans are running at maximum speed. A 15-minute maintenance window has been approved to restore proper cooling without removing the server from the rack. Which tool is the BEST choice to clear the obstruction quickly and return the system to a safe temperature?
A loopback plug connected to the server's network interface
A digital multimeter set to measure the power-supply rails
A household vacuum cleaner with a plastic hose to remove the dust
A can of compressed air directed at the vents and heat-sink fins
A can of compressed air is specifically recommended by manufacturers and training guides for clearing dust from server vents, fans and heat-sinks. Blowing short, upright bursts of compressed air dislodges debris, immediately improving airflow and lowering component temperatures without extensive disassembly. Household vacuums are discouraged because the plastic hose and fast-moving dust can build up static electricity that may damage electronics. A loopback plug and a multimeter are valuable for network and power diagnostics respectively, but neither addresses the immediate cooling problem caused by dust buildup.
