Cleaning The Filters - Fractal design DEFINE R4 Handbuch

Cleaning the filters

Filters are installed at air intakes to prevent dust from entering the case. To ensure optimal
cooling, filters should be cleaned at regular intervals.
•
To clean the PSU filter, simply slide the filter toward the rear of the case and remove it;
clean dust accumulation from it.
•
To clean the front filter, open the front door, push the symbols on the hatch behind the
door to gain access to the fan holder. Remove the fan holder by pushing the small re-
lease mechanism on its top. The filter can then be cleaned directly by hand or it can be
cleaned with water if detaching it from the fan holder plastic.
Mounting additional fans
Rubber spacers are included for mounting additional fans in the optional top or side panel
positions in Define R4; spacers eliminate direct contact between the fan and case, which
helps prevent vibrational noise.
Construction / design
Motherboard SSD mounting positions
For maximum use of the space between the motherboard and the side panel, Define R4
computer cases feature an additional mounting option for two (2) 2.5" solid state drives
(SSD) behind the motherboard.
SSDs should be mounted to the motherboard plate prior to installing the motherboard in the
case; drives should be mounted with the SATA connector pointing forward and with straight
SATA & SATA power cables – 90° cables are not supported.
Power / HDD activity LED
Define R4 features a power LED; by switching the connectors on the motherboard, the
power LED can function as an HDD activity LED. In either case, this connection to the moth-
erboard is optional; computer functionality is not dependent on connection.
