Streacom Unveils Cube-Shaped DB4 Fanless (HSF) Chassis

Streacom recently showed off a new cube-shaped case called the DB4. The new case measures 250 x 250 x 250mm (a bit under 10 inches cubed) and doubles as a passive heatsink for internal components.

The Streacom DB4 is a large cube with vertical finned sides that is held aloft by a thin angled bar. The case is intended to be used as the base for a passively cooled desktop PC. Each side of the cube-shaped DB4 case can cool 65W TDP parts, for a total cooling potential of 260W. In addition to being able to cool processors and low-end graphics cards passively, the case also cools the bundled ZeroFlex 250W fanless power supply.

Unfortunately, Streacom is not showing off the internals or detailing how the PC components are connected to the side(s) of the case. When asked for details by Fanless Tech, Streamcom responded that "we will reveal the internal alyout after all patents are through."

Streacom expects to have the case available for sale sometime between late September or early October for 200 Euros. This is a neat case that is not only fanless, but a work of art. I could see myself using this. What do you think about the Streacom DB4?

Introduction and Features

SilverStone was one of the first PC power supply manufacturers to design and market a fanless power supply for silent operation. While many of their competitor’s fanless products have come and gone, SilverStone continues to build on their reputation and later last year released the SST-ST50NF 500W fanless power supply, which is the latest addition to the Nightjar series. We are a little late to the party in reviewing the ST50NF but after talking with the good folks at SilverStone it appears the wait was worth it as they have continued to tweak the design in recent months to improve AC ripple suppression on the DC outputs.

Here is what SilverStone has to say about the Nightjar 500W fanless power supply: The fanless Nightjar series power supplies are long favorites for professionals and enthusiasts alike that require noiseless power solution with no moving parts. With increasing power demands required from modern computers, SilverStone engineers have once again created another fanless power supply with leading output level in ST50NF. With 500W of continuous rating, near 80Plus Silver efficiency, ±3% voltage regulation, single +12V rail, multiple PCI-E connectors, and full host of safety features, the ST50NF is a great choice for mission-critical systems that need to operate in noiseless or dusty environments.

• 80 PLUS Bronze certified with84%~88% efficiency at 20%~100% load
• Compliance with ATX 12V v2.3 and EPS 12V Specifications
• Strict ±3% voltage regulation
• PCI-E 8-pin and PCI-E 6-pin connectors
• Powerfull class-leading single +12V rail (38A)
• Aluminum construction
• Server-level components
• Universal AC input (100~250V) with Active PFC

Editor’s Note: Fanless PC power supplies occupy a niche market and are targeted towards users who want a silent power supply for use in noise-sensitive areas or who need a power supply that can survive in a dusty/dirty environment that might choke and kill a conventional fan cooled PSU. Fanless power supplies rely on convection cooling and still require airflow in and around the power supply chassis to carry away the waste heat. So while the power supply itself may not have a fan, the computer enclosure must still have some means of creating airflow to keep the CPU, GPU and PSU cool. The last thing you want to do is put a fanless PSU in a closed enclosure without any fans or airflow!
