Fractal Design Define R4 Low Noise Mid Tower Cases

The Fractal Design Define R4 is the latest in the Define Series of computer cases offering minimalistic and stunning Scandinavian design fused with maximum sound reduction, configurability and functionality.

The Define R4 side and front door panels are fitted with dense, sound-absorbing material making it a benchmark for noise reduction. It also accommodates up to 8 HDDs, all modern graphics card sizes, and multiple ventilation options - including two standard Silent Series R2 hydraulic bearing fans - to keep internal components at optimal temperatures.

For ultimate functionality, the Define R4 features a front interface with USB 3.0 and an integrated three-speed fan controller behind the front panel door.

New Features

The updated design incorporates a host of new features which aren’t immediately obvious from looking at the case.

The two supplied fans (fitted front and rear) are now both large 140mm fans so there is more airflow at slower, quieter speeds. The case itself is 25mm wider than the older Define R3 so that you can now fit CPU coolers up to 170 mm tall (when no fan is installed in the side panel). A wider case body also allows for improved cable routing behind the motherboard which is now 26mm wide.

Behind the acoustically lined door, the case sports a new integrated three speed fan controller and a pull down front cover revealing a dual fan bay with an easily removable dust filter and tool-free access to the front fan.

Graphics cards up to 295mm in length can be fitted with the top HDD cage installed, or if your card is longer you can remove the top HDD cage and graphics cards up to 430mm in length can be fitted.

ATX PSUs up to 170mm deep can be fitted when using the bottom fan location; when not using this fan location longer PSUs (up to 270mm deep) can be used.

The front panel has also been improved and now features two USB 3 and two USB 2 ports, audio in/out, a power button with LED and (at long last!) a reset button.

Thick rubber grommets are now used on all holes on the motherboard plate so they aren’t as easy to knock out as those in previous versions of the case.
