I guess I don’t have to introduce Zalman to you – the company is a renowned manufacturer of effective low-noise or completely noiseless cooling systems for CPUs, graphics cards and other PC components. Zalman’s unique CPU coolers are a kind of golden mean – they are the quietest among the most efficient coolers, and the most efficient among the noiseless ones.
Well, you could argue that issue, while the subject of my today’s review is an unarguably unique product. I am speaking about the Zalman TNN500A, a system case for an absolutely silent computer
Here it is: twenty-five kilograms of aluminum, heat pipes, electronics and wires and no fans. Twenty-five kilograms of pure silence!
Closer look: Exterior
The TNN500A looks as solid as a computer case might possibly look. Well, it doesn’t even look like a computer case, but rather like an industrial machine whose exterior is dictated by functionality, not cute looks. Every centimeter of the TNN500A seems to be saying, “This thing is made for hard labor, not to please your eyes”.
The sides of the monster are aluminum panels with vertical ribs. These panels take the most amount of heat generated by the PC components, and their ribs ensure a more efficient transfer of heat to the outside air as the passive cooling concept implies. The top and bottom of the TNN500A are slabs with vent holes:
The top slab has handles to carry the system about; the bottom stands on four wheels of a special design. To steady the computer, you unfold rubber legs at the bottom, which lift the case above the ground.
The face and rear panels of the system are made of aluminum and are fastened to the case in – you can open them as you open a door. The front of the case only has the Zalman logotype and a porthole for a light pipe that transmits the light from the power-on and HDD activity indicators. The rear panel has no openings at all:
