At the bottom part of the front panel, the In Win Mana 136 has a 120 mm fan. This fan has an air filter attached to it. Unfortunately, the manufacturer doesn’t publish the specifications for this fan, which uses a standard peripheral power connector, so it needs to be connected directly to the power supply. This fan glows blue when turned on. You can also install a second 120 mm fan on the front panel, above the existing fan; however, the case doesn’t come with an air filter for this second fan. The installation of the front fans is performed using a tool-less mechanism.

The case comes with two USB 3.0 ports, one USB 2.0 port, and the traditional audio jacks on the top part of the front panel. The USB 3.0 ports use an internal connector, so make sure you install a motherboard with an internal USB 3.0 header.
