Case Cooling – Lots of Options!

Air Cooling

The Corsair Obsidian Series 750D Full-Tower case was designed with good air-flow in mind to keep all your high-end gaming hardware running cool and reliable. There are eight different case fan mounting locations along with support for liquid cooling.

The 750D comes with three Corsair labeled AF140L fans preinstalled. Two 140mm intake fans on the front panel and one 140mm exhaust fan on the back panel. Additional fans can be added (up to 8 fans) if you choose. This provides very good baseline cooling and results in positive air pressure inside the case, which along with the three included air filters helps keep dust out.

The following table lists the noise generated by the three included case fans while operating at different speeds with the side panels on.  Sound Pressure Levels were taken 3’ from the front of the enclosure.  The ambient background noise level was approximately 26 dBA in a quiet room.

With all three fans running at full speed the noise is noticeable but certainly not loud while providing very good airflow through the case.  Slowing the fans down by reducing the voltage (or by adding your own fan speed controller) still keeps air flowing but quiets the case to an inaudible whisper.

The Obsidian Series 750D also supports liquid cooling with four different areas available for mounting one or more radiator/fans of different sizes.
