For computer designers, creating a chassis capable of surviving harsh environments is a tough task, especially if dust is a major problem. Most resort to fanless configuration as this eliminates the possibility of dust buildup introduced by active airflow into the chassis, which is the main cause of system overheating over time. But limited heat dissipation capacity afforded by fanless designs confines systems to lower powered CPUs and Mini-ITX boards with less features.
To overcome this limitation, SilverStone’s R&D team once again challenged and overturned convention by coming up with an answer in the Mammoth MM01 chassis. Instead of completely sealing off airflow to prevent dust, the MM01 has a partially-sealed design with active filtering. To prevent dust from entering the chassis, a HEPA filter is used to cover the air intake area, making MM01 the first retail computer chassis to incorporate this internationally recognized filtering technology. Used frequently by clean room in factories, operating room in hospitals, or facilities requiring dust-free environment, the HEPA filter has the ability to remove airborne particles far exceeding what’s available in traditional computer equipments. In order for this to work without suffocating airflow, two Air Penetrator fans were selected for use in the MM01. With a combined rating of up to 340CFM, they provide air pulling power similar to typical household fans and make it possible to maintain proper cooling for high-end components despite the presence of highly restrictive HEPA filters.
Complementing the tremendous ability to keep dust at bay, the MM01 also has unique, downward slanting front and rear vents to keep liquid from flowing in from the top of the chassis. This simple, yet affective design helps MM01 take on much harsher conditions required by professionals working in places not normally suitable for computers. For those choosing to use MM01 in normal home or office, its superior filtering could potentially help clean up the working environment as well! |

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 MM01’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：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：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 MM01’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：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. Although both types of radiators have the same length, the dual 180mm radiator has approximately 50% larger surface area for much higher performance potential.
A：Usually high resistance introduced by HEPA filter (compared to ordinary computer filters) can reduce the top speed of AP182 by 200rpm. This same effect will apply to any other fan installed in the MM01.
A：HEPA filter will not lose its ability to filter dust when it is clogged, but air flow rate will decrease. If you notice computer temperatures are significantly higher than when new, we recommend replacing the HEPA filter.
