Design and Efficiency – DELL™ AX4-5
Cooling system:Power supply fan produces airflow
For each power supply there are two fans embedded in different places
Flat cooling elements
Effect:The airflow is divided inefficiently because cooling elements are covered by just one part of the airflow
In case of a single fan breakdown, second unit needs to compensate function. Result: Higher load to hardware

Ventilation holes for the power supply
Open rearCooling System: Power supply fan produces air flow Intelligent air conduction between
controllers and power supplies through the ventilation holes
Big cooling elements attached to the connection holes
For each power supply two redundant fans built in a row
Effect: Intelligent conduction of the air flow In case on a single fan breakdown,
no further power consumption therefore no expected hardware damages

Cooling system:Power supply fan produces airflowFor each power supply two redundant fans embedded in different places
Very flat cooling elementsMemory looms into the airflow
Effect:Inefficient air division - cooling elements get covered by just one part of the airflow – however good positioning of the memory
In case of a single fan breakdown, second unit needs to compensate function. Result: Higher load to hardware
