There are many interesting ways to pull heat away from a processor. You can submerge your device in mineral oil or even phase-change fluid (such as "Novec"). You can push cool fluid up to the thing that you are trying to remove heat from and then pump it away through a radiator. If using air, you can make use of vapor chambers and the convection current formed as devices heat up. The goal is to abuse one or more interesting material properties to store energy and move it somewhere else.

Or you can just have an obscene, gigantic mass of metal with more fins than the NHL. According to FanlessTech, these are three heatsinks that are not yet available (and may never be). Two of them have three towers, connected to the base by heat pipes, and the last one has four.

Personally, I would be a bit uncomfortable about buying a PC like that unless I needed absolutely silent or top air cooling performance. The amount that it hangs over RAM or nuzzles against add-in boards seems sketchy to me, especially if you need to swap a DIMM or two at some point, but I always use stock coolers at reference voltage and frequency so what do I know?

Yes, that would be a regular, ATX motherboard.
When will these prototypes become available? Who knows if they even will. Still, if you have a need for cooling solutions that are a little over-the-top, you might be able to get your hands on these some day. There's nothing wrong with adding more mass and surface area, rather than doing something fancy. It works, and it probably works really well.

Tagged: hyper 612, heatsink, fanless, cooler master, cooler
The Cooler Master Hyper 612 Ver. 2 CPU cooler is a member of their "Hyper Series", upper-mainstream product lineup. It looks to be one of the (if not the) biggest offerings in that category. Its extreme dimensions are 139mm (5.47") in length by 102mm (4.02") wide, with a height of 160.4mm (6.32"). It has a 120mm fan which basically takes up a whole side and slowly blows air across it. Some sites claim that it can be used fanless with some (but not every) CPU.
Cooler Master is particularly proud of their "Continuous Direct Contact" technology. In other words, the heat pipes are flattened into a contact with the CPU's heatspreader (or die guard for people like Morry). This eliminates a reservoir of heat before the copper pipes can carry it to the aluminum fins and out into the air.
The heatsink is now available, but no pricing information yet (I cannot find it online).

Tagged: fanless, nuc, haswell
The Akasa Newton X is a fanless case for the NUC form factor that was announced in May and released a couple of months ago. Now, we are beginning to see system builders (albeit in Europe) integrate it in some higher-end devices. This one, from Atlast! Solutions, is built around the Intel Core i5-4250U, up to 1.5TB of SSD storage (512GB Crucial M550 mSATA + 1TB 840 EVO SATA), and up to 16GB of RAM. It can also be configured with up to two-antenna Wireless AC.
The Core i5-4250U is a dual-core (four threads) processor that is rated for 15W TDP. Its on-chip GPU is the Intel HD Graphics 5000 with a peak, theoretical compute throughput of 704 GFLOPS. This makes it a little under three-times the graphics performance of an Xbox 360. In terms of PC games, you are looking at Battlefield 4 or Titanfall on low at 1024x768 (or basically whatever your home server can do if used as a stream-to target).
Prices currently start at £449.00 for 4GB of RAM and 60GB of mSATA SSD, including VAT.
Thanks to FanlessTech for covering this story.

Tagged: msi, kingbox, ms-9a66, fanless, industry, ruggedized
This is not usually a category of computer that we report on, but MSI has just released a fanless, embedded desktop for industrial applications. Silent PCs seem to be talked about more and more frequently, and I am not sure how much of it is industry trends (as opposed to me just paying more attention). Their focus on this design is performance while remaining rugged and, as mentioned a few times, fanless.
Note that it supports CPUs with a maximum of 35W TDP. This leaves room for MSI to include up to a Core i7-4785T in the device, but we do not know if this is actually offered. It has four expansion bays, one PCIe x16 and three regular PCI slots. It does not have an ISA slot, though. I am sure this will be disappointing to some enterprises, and Josh. He probably still has a graphics card for it. You might think I would be joking. I am, but sadly I also am not.
For power, the device can accept anywhere from 9 to 36V DC. Basically, it seems to be based on laptop components with expansion slots for add-in boards. You can also purchase a fan "module" for it if, for one reason or another, it is still the best PC for the job even if it wasn't fanless.
Pricing and specific availability are not provided, but it is apparently released.

Tagged: transquil, monoone, all-in-one, fanless
This announcement does not have too much information to go on, but Tranquil PC is launching their MonoOne all-in-one PC at the end of the month. It will be fanless and milled out of solid aluminum. This solid chunk of metal helps keep the device cool. It is a large mass of metal with fins cut out of it for extra surface area.
Specifications are not listed. We do not even know the screen resolution, processor, drive, I/O ports, or RAM. Current speculation is that it will use a low power Core-level CPU. It looks like it has a removable metal stand and a VESA mount for the wall. In fact, it looks like the stand is attached by the bottom two wall-mount points but I cannot see for sure.
The MonoOne launches at the end of September.

Tagged: fanless, passive cooling, noctua, NH-D15
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.

Logic Supply's LGX ML300 lineup offers you choices from an empty case to a pre-built system costing over $1000, allowing to pick and choose the HTPC system you want. The case is completely fanless and the system sent to Silent PC Review consisted of a Core i5-3427U, 8GB DDR3-1333 and a 128GB mSATA SSD. The outputs offer enough choice for most users, a pair of USB 2.0 ports, two mini DisplayPort a mini-HDMI and gigabit LAN. Thermal performance was great with this case compared to some previous NUCs and SPCR had no issues with overheating during their tests.
"A slim, silent, fanless case for an Intel NUC with room enough for a 2.5" drive is Logic Supply's latest passively cooled project. With the right NUC innards, it becomes a perfect ultra-mini media PC with both zippy performance and enough storage space."
