Product Overview

The Fractal Design Define S lends the appearance, sound dampening technology, and support for a wide variety of components from the widely popular Define Series, while introducing a new, innovative internal layout. The Define S case is packed with intelligently designed enthusiast-oriented features delivering a silent case with powerful and expansive air and liquid cooling support, presented in a stunning Scandinavian inspired construction.

The modernized internal layout of the Define S omits the optical drive bays, instead focusing on a clear straight airflow path and uncompromising water cooling support.

The Define S case reaches the highest level of silent computing through strategically placed dense sound-absorbing material, multiple ModuVent™ fan vent covers and finely tuned Dynamic Series fans.


• Optimally designed for silent computing, while not compromising on airflow and cooling capabilities
• Innovative internal layout, providing a perfectly straight airflow path to the CPU heatsink for air cooling set ups or extensive radiator mounting possibilities for water cooling set ups
• Extensive water cooling support for a case of this size; housing radiators up to 420mm in the top and 360mm in the front
• Including smart reservoir brackets; featuring drill-free reservoir mounting on the front of the motherboard tray and pre-drilled pump mounting holes on the bottom panel
• Equipped with ModuVent™ fan slot covers providing the option of additional cooling or maximum sound absorption
• Including two Fractal Design Dynamic GP14 140mm fans developed for superlative airflow while still maintaining low noise levels
• Maintaining a dust-free interior with dust filters that cover the front and bottom air intakes
• Introducing newly designed hard drive trays placed vertically behind the front partition of the motherboard tray; Three sturdy steel trays with vibration-dampening grommets allowing for installation of one 3.5" or 2.5" drive on each tray, without disrupting the airflow or interfering with the radiator mounting possibilities
• An additional 2 dedicated steel SSD trays cleanly placed behind the motherboard tray
• Long motherboard tray extending to the front panel contributing to an extremely clean build, hiding both hard drives and cables
• Large window side panel
• Define S available in both Windowed & Non-Windowed Editions

Question  280mm compatibilty by Talisin

I was wondering if this case is compatible with the Corsair Hydro Series H110 CPU cooler.
thanks. With the measurements from the Corsair

Answer by shaund on Monday, May 18, 2015
This case has support for 280mm radiators and a maximum thickness of the radiator and fan of 55mm, looking at the Corsair website the combined thickness of these two would be 54mm, with such a small margin it's hard to guarantee that it would be compatible.
