Sure, humans may disagree that 67C (153F) is cool, but it is for a semiconductor. More impressive, it was the temperature recorded on a CPU with a 150W TDP attached to a fanless Noctua NH-D15. Does that mean it was noiseless? Nope. The test kept each of the case fans maxed out at 12V input DC (100%).
This, without the fans.
Hardwareluxx does not specify how much air gets blown across the passive cooler. Their claim is that the case fans just ensure that the ambient temperature is as low as possible. That seems fair, but I could also, for instance, blow cool air through a 3-inch drier hose attached to a bathroom suction fan stuck out the window. That would certainly keep passive coolers chilled while only being technically fanless.
Theoretically, of course. I'm not saying it's something I did in high school or anything...
Depending on how long of a hose is used, it could even be noise in a different location (rather than case fans in the same PC). Still, cooling 150W is a feat in itself. Then again, with over two pounds of heat fins, it makes sense.

Because fanless and cheap PCs are awesome, MINIX is launching the Neo Z64. Priced at $129 USD, it will contain an Intel Atom Z3635F SoC with 2GB of DDR3L and 32GB of eMMC internal storage. The device will ship loaded with Android 4.4.4 (KitKat) but is compatible with Windows 8.1, if you have a license for it.
Externally, the device features a microSD card slot (maximum size not specified), one 10/100Mbps Ethernet port, two USB 2.0 ports, an IR receiver (with remote), and HDMI 1.4. Note that HDMI is the only audio outputs on this device, which could be tricky if you want to run it as something other than a home theater PC (if you do not have a USB sound card that is compatible with your chosen OS). Lastly, it also has 802.11n and Bluetooth 4.0 wireless support.
This is still a significant price premium over some other devices, like a Roku, but could be useful for some. The lack of any SteamOS mention is a bit disconcerting, given that the free OS could be applied to turn the device into an In-Home Streaming target (or host of simple, Linux-compatible games, like Super Meat Boy). Hopefully, future products will consider Valve's home theater platform.
The MINIX Neo Z64 will be available in October for $129.

Tagged: SFF, mini ITX, gigabyte, fanless, essence, Bay Trail
Gigabyte recently rolled out a new small form factor case called the Essence for DIY PCs. The chassis measures 300mm x 234mm x 74mm (~11.8" x 9.2" x 2.9"), comes bundled with a 120W PSU, and will happily hold a Mini ITX motherboard and laptop-sized hard drive. Large mesh vents on the side panels allow for plenty of airflow and ventilation to run a fanless system.
The Essence case uses a SECC frame along with ABS plastic. A rectangular base, which hosts the front IO ports, holds the machine vertically and at a slight backwards tilt. The DC power components are mounted to the bottom of the motherboard tray and are driven by a 120W external power supply (Similar to the type of setup the Xbox 360 uses). The red removable motherboard tray (accessible via the right side panel) allows you to screw in a Mini ITX motherboard and a single 2.5" SSD or HDD up to 9.5mm thick.
The front IO includes two USB 2.0 ports, one headphone output, and one microphone jack. Aesthetically speaking, the Essence looks nice with its red faceplate, silver power button, and black mesh side panels with embossed shapes. It is small enough that it could easily sit next to a monitor and act as a low power desktop or next to the TV as a home theater PC. So long as you do not mind it not fitting into an AV rack/stack, this case could be used along with a cheap SSD and fanless Bay Trail or Kabini-based system for a silent media box or streaming client for Steam games.
The Gigabyte Essence is now available in Japan for 13,800 Yen or approximately $125 USD. It comes with a one year warranty. There is no word yet on availability in other countries at this time, however.

New Intel CEO Brian Krzanich took the stage at IDF 2013 to talk about Intel's future and the PC market. The CEO believes that there is more innovation in the PC than ever before as the company introduces new Haswell and Broadwell chips, new form factors are being experimented with, and Intel moves from traditional CPU to SoC type of architectures.
Two such chips that Intel showed off that are aimed at consumer PCs include a new Haswell-Y chip and the launch of a 14nm Broadwell SoC.
Haswell Y is an ultra low power variant of the Haswell processors that have been avaialble in desktops since June. This new chip is a 4.5W TDP chip that will enable fanless mobile devices such as laptops and slate tablets. The x86-64 chip will allow fanless mobiles that run Windows and should be a good bit more powerful than current Atom-powered Windows mobiles!
A fanless Haswell Y system.
In addition to Haswell Y, Intel is introducing a 14nm Broadwell SoC. The Broadwell chips will be used in both servers and consumer products in 2014.
The 14nm Broadwell SoC.
Interestingly, it looks like Intel is well on its way to shipping chips as Intel showed off a working laptop with the Broadwell chip at IDF today. Further, Intel announced that the Broadwell chips will be shipping by the end of the year!

CompuLab has announced a new fanless, small form factor PC called the Utilite. This new PC comes from the same company that engineered the MintBox, MintBox 2, and Fit PC series. The Utilite is a low-power desktop PC powered by a quad core ARM Cortex A9 processor and runs either Ubuntu Linux or Google’s Android operating system.
The upcoming Utilite measures 5.3” x 3.9” x 0.8”(135 x 100 x 21mm) and consumes anywhere between 3W and 8W of power depending on the particular hardware configuration. It is designed to be a quiet desktop replacement with plenty of IO.
CompuLab will provide single core, dual core, and quad core CPU SKUs. Specifically, the Utilite is powered by a Freescale i.MX6 ARM Cortex-A9 MPCore processor that is clocked at up to 1.2 GHz. Users will be able to further configure the system with up to 4GB of DDR3 1066 MHz memory and a 512GB mSATA SSD. Storage can be further expanded using Micro SD-XC cards (maximum of 128GB per card). The GPU in the SoC is compatible with OpenGL ES 1.1 and 2.0 as well as OpenVG 1.1 and OpenCL EP. It is capable of hardware decoding multi-stream 1080p video in a variety of common formats.
Wireless functionality includes an 802.11b/g/n Wi-Fi card and Bluetooth 3.0.
The Utilite has a dark gray case with silver front and rear bezels.
The front of the Utilite PC features the following IO options in addition to the power button and indicator LEDs.
- 1 x USB OTG (Micro USB)
- 1 x RS232 (ultra mini serial connector)
- 1 x Micro SD card slot
- 2 x USB 2.0
- 2 x 3.5mm audio jacks (line in, line out)
The rear of the PC hosts:
- 1 x DC power input
- 1 x Wi-Fi antenna
- 1 x RS232 (ultra mini serial connector)
- 2 x USB 2.0
- 2 x Gigabit Ethernet RJ45 jacks
- 2 x HDMI video outputs
According to fanless PC guru FanlessTech, CompuLab will be releasing the ARM-powered Utilite mini PC next month with a starting price of $99 and a variety of SKUs with varying amounts of CPU cores, memory, and storage. The Utilite PC is a bit on the expensive side, but this is a system for industrial and enterprise use as well as consumers, and Olivier from FanlessTech notes that build quality should be on par with those goals/industry aims.

Tagged: Passive, Logic Supply, Ivy Bridge, fanless
Logic Supply recently responded to customer requests for a high-end passively cooled system with its new LGX ML250 fanless PC. The new system is intended for industrial and mobile computing work where you need a rugged system that can be used in a wide range of environments.
The LGX ML250 uses a metal chassis that doubles as a heatsink for the CPU. On the front of the case is a single power button and two USB 2.0 ports. On the rear IO panel, users are presented with:
- 2 x COM ports
- 1 x DisplayPort
- 1 x HDMI
- 1 x DVI
- 1 x PS/2
- 4 x USB 2.0
- 2 x USB 3.0
- 2 x RJ45 LAN jacks
- 3 x analog audio outputs
Internally, the fanless PC uses an ASRock IMB-170 motherboard, Intel Sandy Bridge or Ivy Bridge CPUs, up to 16GB (2x8GB) DDR3 memory, and (up to) either a 1TB mechanical hard drive or 120GB SLC SSD for two SATA drive slots.
CPU options include the Sandy Bridge Celeron B810, the Ivy Bridge Core i3-3120ME, or the Ivy Bridge Intel Core i5-3610ME at 2.7GHz. The PC also includes Wi-Fi via a mini-PCI-E card. It can be pre-installed with your choice of Windows 7/8 or Ubuntu Linux operating systems. The LGX ML250 is rated for 40-degrees Celsius environmental temperatures.
Mr Walsh of Logic Supply stated that the company received numerous requests for a sub-$1000 machine with decent specs, IO, and with a fanless design. "The default config uses one of the new industrial-series ASRock boards -- the IMB170. From what I can tell, few IPC companies are using these boards in fanless systems, which is amazing given their price/performance specs."
The ML250 starts at $773 and is available for pre-order now. The price tag is steep, but it is a full system that is mostly aimed at industrial applications.

Tagged: streacom db4, streacom, hsf, Fanless PSU, fanless, cpu cooler
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?

Tagged: SFF case, SFF, passive cooling, nimbus, heastink, fanless, cpu cooler, cirrus7
German PC manufacturer Cirrus7 has launched a new small form factor (SFF) PC called the Nimbus that uses slices of aluminum that do double duty as both a case and a passive CPU cooler (heatsink).
The Nimbus PC features an Intel DQ77KB motherboard and low-power Intel processor along with configurable DDR3 and mSATA storage options. The base model will come with 4GB of DDR3 and a 60GB mSATA SSD. CPU options include the Intel G1610T, G2020T, Core i3-3220T, i3-3470T, i5-3570T, and i7-3770T. From there you can add up to two 7mm 2.5” hard drives (or SSDs) and increase the amount of RAM (for a higher price, of course).
The Intel DQ77KB board supports vPro and KVM over IP on systems with the Core i5 or higher processor. It has the following external IO options:
- 4 x USB 3.0
- 4 x USB 2.0
- 2 x Intel Gigabit LAN
- 2 x Audio jacks (green jack is dual purpose, mini-TOSLink compatible)
- 1 x HDMI
- 1 x DisplayPort
The SFF PC comes preloaded with either Ubuntu 13.04, Ubuntu 12.04, or Windows 8 (depending on your choice at checkout).
Check out more photos of the Nimbus at FanlessTech.
In order to keep the hardware cool, Cirrus7 has opted for an all-aluminum enclosure that is built around and over the motherboard in a fin-spacer-fin pattern. Each aluminum fin is 12mm high and the height of the system can be varied by adding or reducing the number of fins used. For example, using all fins allows Cirrus7 to support higher TDPs like the Core i7 3770T. Alternatively, if you are just using an i3-3220T, you could get by with a smaller (and lighter) case/heatsink. Notably, judging by the hands-on photos over at FanlessTech, the Nimbus does not use a copper CPU block which may have reduce the heatsink's effectiveness. That, or maybe Cirrus7 expects that they have slapped enough aluminum fins on the system that it doesn't matter much (heh). Also note that the case is not completely sealed, so although it is passively cooled, it is definitely not water or dust proof. Beyond that though, the case looks nice and the system would make a nice silent backup server, router, or HTPC!
The Nimbus will be available towards the end of June in Germany and Europe, with worldwide shipping available upon request. The system starts at €499 for the base model which is approximately $640 USD (before shipping). That price includes the case, processor, motherboard, RAM, and mSATA drive. Cirrus 7 has stated that Haswell-based models of the Nimbus will be available at some point, but are not expected until around the end of 2013 at the earliest.
