The fans contain a patented vibration absoption in order to lower the noise level further. HDD Muffler Harddisk noise and vibration are eliminated by encapsulating it into absorbers. A HDD cooler keeps it at a low temperature. Torsionproof Chassis The mechanicaly optimized construction using 0.
Optional Air Hood To enhance the cooling performance, an optional Air Hood may be installed at the backwall. Air Hood 1 is recommended if the cooler fan blows air down towards the CPU. Air Hood 2 is recommended if a tower CPU cooler is used. Long Service Life The power supply is the most common cause of shut downs or system instability. Despite this fact in most cases low quality power supplies are still found in today's PC. Sadly, we would quickly come unstuck, as you will read on the next page.

This had to be done to accommodate the dual 80mm fans. It allows for a very open airflow path through the PSU especially with the bottom grill for the PSU exhaust being so unrestricted. The normal power supply location has two 80mm exhaust fans. These fans are connected directly via a dedicated lead that goes into the PSU.
The voltage appears to be thermally regulated. The airflow in the Silentium T2 is explained by this diagram from the Silentium product page. Air is drawn in from the rear of the case and exhausted at the top. A secondary air path runs through the power supply out the bottom front of the case.
A quick look at the airflow diagram makes sense of what Arctic Cooling is trying to do with this case. In a conventional ATX case, the components that need the most cooling, the CPU and the video card, are not cooled efficiently because the air that is drawn in via front mounted intake fans is warmed by other components in the air path.
In the Silentium, the air intakes are located directly beside the CPU and the video card, meaning that the air that cools them is drawn directly from outside the case before other components have a chance to warm it up. These are all the intake vents.
Intake vents are located on the bottom and the rear panel. This is the bottom of the case. The two grills on the left are intakes, while the grill on the right is the exhaust for the PSU. The two black knobs in the middle serve as feet to prevent the case from sliding around in the base.
The case sits in a black base that raises the case about half an inch to make the bottom open to the air. It also isolates the intake air at the rear of the case from the exhaust at the front.
Damage sustained during testing. The air-channelled plastic base raises the case about half an inch above the ground. There are two separated airflow routes: Intake at the back and exhaust for the PSU at the front. None of the intake vents are filtered, so keeping a system clean in this case will prove a challenge especially in a carpeted room.
The next photos show case is cradled in the plastic base, which really is an integral part of the entire design. Also, the AC plug is positioned at the bottom corner of the back panel.
Here are exhaust vents for the PSU at the front of the case. PCI cards are mounted without screws with a hinged retention bracket. Here is the final innovation of the Silentium case: The HDD Muffler , an elastically suspended aluminum box into which the main hard drive can be placed for both quieting and cooling purposes.
Small rubber O-rings in the corners provide just enough flexibility to float the aluminum box when a hard drive is inserted. With the unusual airflow management in the case, it comes as no surprise that the front bezel is completely sealed.
There is room behind the plastic bezel to install some noise or vibration damping for those who are so inclined. The bezel is completely solid; the case is designed not to need airflow from the front. This should be good for noise levels, as it prevents direct sound paths. Relocating the PSU to the front of the case means that all power cables now originate from the bottom front corner of the case. This is probably a slight improvement over the standard ATX layout, as it keeps the cables out of the intended air paths.
The cables are routed parallel with the back edge of the motherboard which keeps them close to both the drives and the motherboard itself. However, the cables from the front bezel are unavoidably routed directly through the fresh air path of the power supply, so the usual cable clutter around the air intake of the power supply is not avoided.
The HDD Muffle r is located parallel to the power supply. This is quite an efficient use of space, but, because it is not located near any other drive bays, it means that the IDE cable required for the suspended drive cannot be attached to any other devices. Of course, using a second, unsuspended, hard drive in a case like this would defeat the purpose of suspending the first drive.
In practical terms, this means that the case is limited to only a single hard drive if it is to be used for quiet computing. The rest of the drives may be mounted without tools, Accessing all of the drive bays including the secondary internal bay requires removing the front bezel, which makes installing optical drives a little more involved than usual. Luckily, the bezel is easily removable by lifting up three clips along the side of the bezel.
The base could have been better implemented. Seating the case on its base requires a certain amount of finesse, and when they finally fit together the case falls into place with a sudden drop that may not be good for the delicate components inside.
Furthermore, the vents have sharp fins that make moving the case a bit painful if you put your hands in the wrong place. The base is made out of brittle, low-grade plastic that breaks easily; we broke two of the fins early on during testing by putting the case down at the wrong angle.
This case should never be used on a carpeted floor. Not only would dust collect rapidly, but both the bottom intake and the PSU exhaust vents could be blocked, especially with longer fiber carpets.
Overheating would be far too easy. It is impossible to take the side cover off without first removing the base. Removing the cover while there is a system running inside is a delicate and potentially dangerous procedure.
As mentioned, the interior dimensions of this case are very tight. Installation was a delicate procedure, especially with all the cables from the PSU running along the edge of the Muffler. On the whole the cables were quite short as is appropriate for a case of this side. However, the cables for the front connectors were a couple centimeters shorter than we would like.
The header for the external headphone jack on our board is located near the rear edge of our motherboard not an uncommon position , and the necessary cable was barely long enough.
Installing a large AGP or PCI card next to the header might have put the cable under tension or made it too short altogether. A tight fit, with few options for cable management. The front audio cable was just barely long enough. The HDD Muffler consists of an aluminum box with a plastic cap that clips on. The cap is lined with a strip of rubber that presses against the edge of the hard drive to prevent it from rattling inside the box.
Our hard drive fit snugly, and vibration was never an issue during testing. Installation of the Muffler proved more difficult than expected. Unfortunately, the cap is made out of the same brittle plastic as the base, and one of the clips snapped off far too easily the first time we tried to remove it.
Also, removing the cap requires lifting two of the clips and pulling the cap away from the box. One of the clips is hidden by the support frame and is only accessible with a flathead screwdriver.
Although our test rig did not require it, we also installed a hard drive in the unused internal bay using the screwless mounting system. Because of the orientation of mounting rails, the hard drive had to be installed through the front of the case with the bezel removed. The HDD Muffler in use.
The inside face of the cap for the Muffler is lined with rubber to prevent the drive from vibrating inside the box. Note clip missing on top left corner; it was broken during testing. Our test system was quite basic, and was intended to reflect a typical low-to-mid power system. Only the integrated VGA was used. Temperature measurements should thus be comparable between the two reviews, and some judgment of how the Silentium compares to an open test bench can be made. Noise levels between the two reviews are not comparable, however, as this review is intended to show how effective the Silentium is at damping noise, while the SS4UTC review was designed to test the noise levels of a specific heatsink.
Total system draw was 58W at idle, W during folding, and W during burn, measured at the AC outlet. Our first test was done with the system at idle, placed on the carpeted floor in the quietest room available in order to establish a reference noise level for the case itself. Ambient noise level was 16 dBA. Although the exhaust fans and the PSU fans appear to be identical, they do not start off spinning at the same speed.
