Reducing Flow Restriction across panels

Large holes provide low flow restriction, making it easier it is for air to cross from one side of the plate to the other, preventing stoppage of flow. This is especially important when it comes to passive cooling, where too much flow restriction can trap the heat within the case.

​

Linear Airflow Paths

For every 90º Turn made by flowing air, there is a loss in pressure and velocity. Winter One maintains linear airflow in the solid side panel configuration. With perforated side panels, the path air takes is limited to one 90º turn to provide each radiator with the necessary flow.

Acoustically Optimized Panels

Perforated Plate geometry, and distance from the plate to the fan blades has been carefully controlled, in order to create multiple, smaller transitions to turbulent flow, This spreads one acoustic peak into 3 separate peaks, creating a more pleasant noise profile to the human ear.

​

Eliminating Internal Surfaces

Surfaces that air flows against create boundary layer drag. Great care was taken to remove internal surfaces inside Winter One. Eliminating the central spine allows air to flow cleanly through the enclosure.

​

Backflow Barriers on the End-plates

When fan speeds are pushed higher, air had a tendency to loop around and re-circulate. The geometry of the inside of the end plate was altered, in order to provide a physical barrier to limit the backflow of air, further improving efficiency.

Optimized Foot Height

Many small form factor cases use the smallest possible feet to avoid adding volume. However, this drastically harms cooling, whether the case is set up for intake or exhaust at the bottom.
