Today I will taking a look at the Silentium 920 case from AZZA, but first a little background information on the company. Founded in 1996, AZZA entered the market as a motherboard manufacturer for the PC industry before rising to become one of the top ten leading suppliers worldwide in the 90's. In 2004 AZZA began manufacturing computer cases, and further expanded upon their offerings by entering the gaming product sector. At this point they began manufacturing a variety of OEM products including computer cases and power supplies for XION. 2009 ushered in more changes as AZZA realigned and established their own label and began distributing products under their own trademark.

AZZA's Silentium 920 mid-tower case is available in two colors, white or black, indicated by the model number. We'li will be looking at the CSAZ-920B model. The Silentium 920 comes packed with features like two 120mm fans located in the front and back of the case, and 5 external drive bays: 4 5.25" and 1 external 3.5".

Taking a quick look at the packaging for the Siletium 920, the box is covered with information regarding the features and benefits of the case. The front of the box contains information regarding the noise reduction material, hard drive holders and support for USB 3.0. Flipping the box around to the back, we are presented with a pair of diagrams and details regarding the other features not mentioned on the front, for instance the 5.25" drive bay quick mount latches, front panel with power switch, USB and audio outputs. Located on the bottom of the Silentium 920 is an air flow vent and filter. These are just a few of the features available in the Silentium 920. As we dive deeper into the case we will cover everything in greater detail.

AZZA's Silentium 920 exterior has a matte black finish that (in my opinion) looks great and does a much nicer job of keeping finger prints off. Overall the front of the Silentium 920 has a nice clean look thanks to the front door that covers the 5.25" drive bays. Located just below the door is the power button and along the right side of the case is the USB 3.0 port, audio in/out jacks and the reset button.

Located at the rear of the case is another 120mm exhaust fan. The Silentium 920 has 7 expansion slots which allow for a 3-way SLI/CrossFireX configuration; if your GPU's are watercooled then you just might be able to squeeze a 4-way configuration in. For those of you who prefer watercooling over air, to the right of the expansion slots are 2 openings that allow for the use of an external radiator or reservoir.

One feature missing from the Silentium 920 is a side window, so hopefully AZZA will consider one in a future revision. Honestly I don't see this as an issue for those who enjoy case modding, who might see this as a chance to express their creative side. Another feature we are beginning to see more of especially in mid-towers is the addition of extruded sides, to allow ample room for cable management.

The Silentium 920 has a 1 inch clearance underneath, leaving adequate room for ventilation should you choose to install a 140mm fan in the lower vent. One thing to keep in mind is that to do so, you must remove the sound dampening material that covers the vent.

Located at the bottom of the Silentium 920 are two vents that allow you to mount the power supply upside down, which should prove assuring for those worried about adequate airflow for cooling. The other vent is covered with a sound dampening material that can be removed and replaced with a 140mm fan as described earlier, allowing for an increase in airflow to the graphics cards.

The Silentium 920 is spacious enough inside to accommodate five internal hard drives and a 3-way SLI/CrossFireX graphics card configuration. The fifth external bay is actually a hidden 3.5" drive bay; this is an excellent place to install an 45GB Accelerator drive that will give a nice boost to your mechanical drive (for example). The white buttons in the upper right are the 5.25" drive bay quick mount latches.

The motherboard tray retains the cutouts that allow for the routing of cables, but unlike other cases on the market they do not have any type of protective cover around the edges to protect the cables from accidental cuts and tears. Normally this would concern me but the edges have a nice round and smooth finish to them, so AZZA scores some points for taking this into consideration during the manufacturing of the Silentium 920.

On the other side of AZZA's Silentium 920 you have a total of thirteen cable tie downs to assist in cable management.

With five hard drive trays, the Silentium 920 offers ample room for your storage needs. The hard drive trays differ slightly from traditional trays as these have plastic pins molded into the frame instead of requiring screws to secure the drives themselves. Just above the drive trays you can see the hidden 3.5" drive bay. Again this bay can be used for additional internal storage, or you can use the optional faceplate and mount a card reader in this bay.

The Silentium 920 is cooled by a pair of 120mm fans manufactured by Globe (specifications are 1,200 RPM, 45.2CFM with a rated noise level of 22.3 dBA; power draw is 0.26A at 12V).

The sound dampening material used to insulate the Silentium 920 has been applied to the top, bottom and both side panels, and measure a 1/4" thick. This should provide adequate noise reduction when both the processor and graphics card fans are running at their maximum rotational speeds.

The bundled accessories package contains the standard hardware, with the exception of the motherboard speaker and 5.25" drive bay faceplate that will allow you to mount any accessory that fits into a 3.5" opening. Other contents include the hard drive, optical drive and motherboard screws and standoffs, and two resuable and two disposable cable ties.

To test the Silentium 920 I will be utilizing the OCCT suite. I will run the test suite for 30 minutes with both the case and graphics card fans set at their highest rotational speeds. Temperatures will be recorded using HWMonitor, and the highest recorded values will be used for the load test. For the idle portion of the test, the system will sit idle for 30 minutes allowing temperatures to stabilize; the lowest values will then be recorded.

Test Results:

The Silentium 920's performance was outstanding, taking into consideration the sound dampening material and only two cooling fans. I will admit that the sound dampening material failed to truly silence the noise level from the 7970 GPU with the fan at its maximum rotational speed, but that couldn't detract from the Silentium 920's excellent cooling capabilities.

AZZA's Silentium 920 was a pleasure overall to work with, though it has a few minor areas that could be tweaked. The first one that comes to mind is the 5.25" drive bay's quick latch system. While installing the optical drive in the upper slot, the knob for the bay can be a little difficult to work with; the spacing between it and the lip of the case is rather tight fitting, making it difficult to latch. Another thing which could be improved is the sound dampening material, though generally speaking it works well enough for the noise generated by the CPU and graphics card fans. Meanwhile the back of the motherboard tray tends to interfere with cable management, so you need to apply a little more pressure from the outside of the case to get the side panel on correctly.

The Silentium 920 would make the perfect HTPC build or for gamers who tend not to overclock their components, as this will allow them to run their fans on auto speed settings to better provide a whisper-quiet movie or gaming experience. The sound dampening material works like a charm with the cooling fans set on auto, but they'll prove less effective if you set your cooling fans to manual speed settings and crank them up.

The Silentium 920 is still a viable solution for your needs if you enjoy overclocking and don't mind a little noise coming from your system. Remember that it's got room for up to six hard drives without the need of mounting adapters, and with support for up to a 3-way SLI/CrossFireX setup you can fit quite a little beast in there. With a MSRP of $99.99 I would definitely recommend this case to anyone in the market for an affordable and effective upgrade.
