Fortress Series     FT04

■ Two Air Penetrator AP182 fans included for exceptional performance or quietness

■ Removable motherboard tray and top panel

■ Quick access filters with HiFlow Technology to prevent dust buildup

■ Foam padded interior for advanced noise absorption

■ Unrestricted airflow design with unique angled vents minimizes noise and maximizes fan performance

■ Convenient routing pathways for excellent cable management

■ Adjustable holder for large CPU coolers and graphic cards

■ Independent airflow channel for power supply with dedicated PSU filter

■ Accommodates up to seven 3.5” hard drives and four 2.5” SSDs

         Superior combination of cooling performance and silence has always been the key for SilverStone Fortress series’ success and the Fortress FT04 has certainly retained this family trait in fine fashion. For the first time in a SilverStone chassis, two Air Penetrator AP182 adjustable fans are included to provide unprecedented volume of air for their size. With uninterrupted airflow design and new HiFlow fan filter that improves flow rate by nearly 40% compared to its predecessor, the FT04 is capable of astonishing cooling performance despite having only two fans. To contain unwanted noise, foam padded interior is retained from previous designs while new rear-angled front vents guides potential leaked noise away from the user. Although smaller in volume compared to the Fortress FT02, the FT04 can still accommodate up to 11 hard drives and has many nifty features such as CPU and graphic card supporter, removable motherboard tray, and externally accessible fan filter assembly. Wrapping around this technical powerhouse is a stunning one piece-like extruded aluminum front door and top panel finished to the same standard as SilverStone’s premium Temjin series cases. For those looking to upgrade to a chassis with Fortress series’ legendary performance in smaller footprint or a more traditional layout, the FT04 is perfect.

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:The RV04’s airflow path has been optimized using positive pressure design to dissipate heat. The two front 180mm fan will provide equal airflow for both CPU and graphic card area. From our test results, a rear exhaust fan creates an imbalanced airflow that lowers the CPU temperature slightly at the cost of greater cooling performance loss for the graphics card area. Even without an exhaust fan installed the hot air will still exit naturally from the rear. We have also found out through testing that installing a fan directly onto the CPU cooler results in overall quieter case compared to having a fan mounted in the rear exhaust fan slot due the latter’s more exposed location and turbulence against the fan grille. So with all things considered, an exhaust fan is unnecessary with this case’s design, but the rear fan mount is still included for convenient placement of all-in-one liquid cooling solution.

A:The RV04 was designed to achieve optimal silence so there are no fan guards in front of the front fans to reduce noise associated with air turbulence. To reduce the chance of foreign objects touching and damaging the spinning fans while the system is on, we recommend only removing and cleaning the filter when the system is off.

A:A. If your fan is connected to the motherboard, we suggest you to turn off temperature control function in the BIOS. If you want to use temperature control function on your motherboard, we recommend you to set the RV04’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:This chassis supports Kensington security locks to prevent not only the entire chassis from being taken when locked but can also prevent theft of interior components. If the top cover can be removed independently then there is no point in having Kensington lock holes in the first place.

A:Customized liquid cooling systems do not have a definite installation procedure. Typical chassis will not have provision for this. DIY users must make provisions themselves. If you want to install a 3 x 120mm radiator, we recommend Magicool Dual 180 Radiator instead as a better alternative.
