Compact 4U Server Chassis

The iStarUSA D-400-6SE is a 4U rackmount chassis built from steel for server deployments. It accepts motherboards up to 12" x 10" and provides six external 5.25" drive bays plus two external 3.5" bays. Two internal 3.5" bays add further storage capacity. Front USB 2.0 ports allow quick peripheral access.

Single 80mm Fan Cooling

A single 80mm fan handles airflow through the enclosure. A removable air filter helps keep dust out of the steel interior. Power and HDD LEDs give basic status indication. The front panel also includes power and alarm reset switches for direct control.

Sustained Load Thermal Behaviour

With only one 80mm fan, airflow is limited during prolonged heavy workloads. Internal temperatures may rise steadily when multiple drives and a full-size motherboard are active. The removable filter can be cleaned to maintain what airflow the design allows. Builds requiring high continuous throughput should verify thermal margins.

Questions about this item

How do I install a motherboard in the D-400-6SE, and which mounting holes line up with the 12" x 10" tray?

The chassis supports motherboards up to 12" x 10". Align the board with the pre-drilled standoffs on the tray, secure each corner first, then add the centre screws to prevent flex.

What maintenance does the removable air filter need, and how often should I clean it?

Slide the filter out from the front bezel, rinse with water or vacuum the dust, let it dry completely, then reinstall. Check monthly in dusty environments.

With only one 80mm fan, what thermal limit appears first under sustained load?

A single 80mm fan moves limited air, so drive bay and motherboard VRM temperatures rise first during prolonged heavy workloads.
