The Seasonic Platinum Fanless 520W Power Supply ships with a warning notice wrapped around the chassis. As this unit is passively cooled it is important to ensure that the warm air can easily escape.

There are also several vents on the side panels to further improve cooling.

One side of the power supply is fully vented with a power switch and connector set to the side.

The other side of the chassis contains all the connectors for the modular cables. At the side of this panel is a venting hole to further help with heat removal.
