         The Fortress FT05 represent SilverStone’s continued dedication in improving and reinventing computer chassis design. Similar to the RAVEN RV05, it no longer has any 5.25” drive bay and utilizes SilverStone’s fame 90 degree rotated design. Previous full ATX SilverStone chassis with 90 degree layout often had to compromise on space efficiency due to fixed length of the motherboard in rotated orientation. So the elimination of 5.25” bays solves this issue naturally and enables FT05 to be not only more balanced in proportion but stunning in its design thanks to its thick wrap-around aluminum exterior. With majority of wasted space eliminated, the FT05 is better optimized for components that affect performance the most such as CPU and GPUs. The result is an expertly-engineered ATX chassis that is just as capable in terms of compute power and heat dissipation as the first RAVEN chassis, the RV01, but in half the size. Equipped with latest revision Air Penetrator fans that include three speed switches and modern touches such as externally removable filters and tool-less panels, the FT05 has everything that PC enthusiasts could wish for in a compact, high performance computer chassis that is not only cool and quiet, but also easy to build and maintain. For those not wanting to constantly step up in chassis size to obtain top-level performance, the Fortress FT05 is perhaps the best and most beautiful solution.

A:If your fans are connected to the motherboard, we suggest turning off temperature control function in the BIOS. If you want to use temperature control function on your motherboard, we recommend setting the RV05’s physical fan speed switch to high for a lower starting voltage and a wider range of control. If the fans still do not spin, please contact reseller or SilverStone to arrange for replacement.

A:It’s possible but for best balance of cooling and quietness, installing a fan directly on the CPU cooler is usually more effective than installing exhaust fan on rear of the case.

A:Most should fit in the top 120mm fan area. If you have larger cooler, we recommend installing it on the bottom panel.

A:Yes, but to reduce the chance of foreign objects touching and damaging the spinning fans while the system is on, we recommend doing so quickly.

A:If you are thinking about installing a triple 120mm radiator, we highly recommend a dual 180mm radiator such as the “Magicool Dual 180” instead. Although both types of radiators have the same length, the dual 180mm radiator has approximately 50% larger surface area for much higher performance potential.
