SilverStone Fortress FT02 chassis gets reviewed - Revolutionary New Fan Design

Review: Uncompromised aesthetic simplicity, maximum airflow performance

SilverStone’s Revolutionary New Fan Design  

At this point in time, we're sure that SilverStone engineers are aware of the Radeon HD 5970 installation oversight and have considered a solution for enthusiast customers. Indeed, the company has not only designed a better installation solution for Radeon HD 5970 owners, it has also engineered a more efficient ambient heat extraction method at the same time.

Meet the SilverStone Air Penetrator 180mm SST-AP181, a revolutionary fan so unique in design, slim form factor and unmatched efficiency that it could serve the perfect role as any intake case fan or high-density radiator solution. The company demonstrated the technology on YouTube back in May using a smoke machine to show its competitive edge over leading chassis fans in the industry. Best of all, the new fans feature up to 2.45mm H2O static air pressure opposed to 0.98mm H2O static air pressure with the FN181 fans included in the Raven RV02 and Fortress FT02.

SilverStone’s new Air Penetrator SST-AP181 intake fan has been exclusively designed with the goal of focusing airflow into a spiral column that can be “channeled through various obstacles inside the modern computer case for more efficient cooling performance.” As KitGuru recently noted in their thoroughly explained SST-AP181 review, the concept and design motives are in place to ensure that the unique blades and grills on the Air Penetrator can create enough pressure to push air as far as one meter away with minimal speed and noise. SilverStone is pushing this new enthusiast-grade fan as a perfectly capable high airflow unit for supplementing high-density heatsinks and radiators.

While we certainly appreciate the idea that SilverStone included three of its older FN181 fans with the Fortress FT02 in an engineering effort to maximize positive airflow, we must certainly admit that overall cooling performance strongly benefits from the improved SST-AP181 design. Meanwhile, the company also included a fourth 120mm fan resting right above the CPU socket exhaust area. This fan utilizes golf blades for exceptional quietness with emphasis on maximizing positive air pressure. In the game of golf, the dimples of a golf ball serve to reduce drag and air resistance on the ball, thereby giving a longer drive. Likewise, the golf blade design of this 120mm ceiling fan allows for a greater amount of heat to dissipate from vital components and lowers overall ambient CPU temperatures. Consequently, it is the only fan on the entire chassis that does not have a dust filter as it does not require one.

I just hope they've included usb 3.0 :sad:

Nice... a big roomy chassis that doesn't look like some fugly "elite gamerz 9000 uber sniper destroy super-bright blue L.E.D edition" gawdy cheesefest case.

good job Silverstone:)

i dont see number comparisons from other cases and this one.. in celcius that is... how much cooler did it get. 10 celcius cooler ?

I chose not to focus on a quantitative assessment of its airflow performance in comparison to similar market offerings.

Rather, I highlighted the aerodynamic concepts behind SilverStone's cooling methodology in the Fotress FT02 and compared them against its own physical design traits, overall chassis contours, and its ability to maintain a simplistic overall body design.

I wish it came it white, it would look really good.

USB 3.0? That's completely down the motherboard manufacturer unless you're talking about the front panel. In that case, I'm sure they didn't. That won't be around for awhile.

yes and it all sounds nice and looks shiny, so did the fermi. how can you say you compared anything all you did was explain its features. comparing is using numbers. how much better is it coming from silverstone? xx% i think that would be comparing. I'm not trying to sound like an A$$ but if u can explain for 8 pages how great the design is at least show us what practical means that will have. how good will it be at cooling thats all it comes down to. unless u only care about looks and interesting airway passages.

Nice and sleek design, not too flamboyant/gimmicky. Although in my opinion, you could of maybe compared the temps with other cases, to show how much of an advantage the "stack-cooling effect" has, instead of talking so much about the design. Not criticizing, just making a point here.

About the problem with the 5970, I think I've heard somewhere, that it will fit once you take off the fan grill. Can anyone confirm this?

Yes, removing the fan grill will remedy the issue with Radeon HD 5970 installation as it would allow just enough clearance for the card's 0.2-inch red fins. As I mentioned, however, removal or alteration of any part of the chassis would be considered a "modification" and was not explicitly mentioned by SilverStone in their product documentation or marketing info sheets.
