Early last year startup CoolChip Technologies partnered with Cooler Master to show off a prototype kinetic cooler at CES 2015. The two companies were allegedly working on a new processor heatsink that would be priced in line with current heatsink + fan designs but would be smaller, quieter, and less prone to collecting dust! Unfortunately that revolutionary HSF product never materialized (just like the Sandia Labs prototype), and while we may still see that cooler some day it appears like it is not going to be anytime soon. With that said, it is not all bad news for fans of these promising processor coolers, because if a recent social media tease by the startup is any indication CoolChip technologies has decided to move forward with its own branded kinetic cooler!
Specifically, CoolChip teased a new and upcoming product launch aimed at cooling Intel Skylake CPUs with up to 70W TDPs. Along with the statement that the kinetic cooler is “coming soon!” the company posted three images of the new cooler, and it looks awesome.
Resembling something a Predator might be using to cool their PC, the CoolChip cooler has a stationary base plate with a motor that spins a small array of fins in a manner that facilitates heat transfer from the base plate to the spinning heatsink (which is in lieu of a fan -- the heatsink is the fan) via a very thin layer of air that keeps the heatsink balanced as well. That spinning heatsink portion is then further surrounded by stationary rings of fins likely connected to the base plate using heatpipes for that extra bit of cooling potential. The inner impeller (vertical) fins are angled one direction while the outer stationary ring of horizontal fins are angled the opposite direction. The impeller pulls cool air in and pushes it outwards through the stationary fins and out into the case where case fans will then exhaust that hot air out of the case. CoolChips has an animated illustration of how this impeller design cools versus a traditional heatsink and fan design which is available on their website.
Other features of the small kinetic cooler include a braided cable with fan header to get power from the CPU_Fan header on the motherboard. It is not clear if this connector is 4 pin and supports PWM or not though. One of the more promising bits of this teaser is the photo of the cooler in retail packaging which adds at least a little bit of credence that we might actually see this product launch at some point. The package appears to include the 1U Low Profile Kinetic Cooler itself, a motherboard backplate, and a small tube of thermal paste (TIM).
Possibly the coolest (heh) part of this teased product is the third photo which suggests that there will be multiple color options for the impeller which would allow users to customize the heatsink color to match their PC’s design scheme.
You can check out the post for yourself here. I am really excited to finally see new information on kinetic cooling, and this CoolChip cooler in particular looks really interesting and I hope that it actually materializes and I can finally read some reviews on it! What are your thoughts on kinetic cooling for PCs?

Phoronix has spent a bit of time with the CompuLab Airtop PC, a SFF machine with passive cooling and no moving parts. It sports decent components, an i7-5775C Broadwell processor, 16GB of RAM, 256GB ADATA SSD, and a GeForce GTX 950, with Linux Mint installed and support for just about any other flavour of that OS you might prefer. It also has a very impressive array of outputs on the back including dual LAN ports and antennae for wireless connectivity, two power connectors for redundancy and a plethora of USB 3.0, HDMI, DisplayPort and other ports. Check out this overview of the construction and a quick peek at the performance of this passively cooled machine.
"At the end of February I posted my initial hands-on with the passively-cooled Airtop PC that's been exciting many readers over its unique design and being Linux-friendly. As I hadn't written anymore about it in the past few weeks, some Phoronix readers had emailed me and tweeted, curious what the deal was and if it wasn't living up to expectations. That's not the case at all and the Airtop PC continues to exhibit great potential and is yet another solid offering from CompuLab."

While there were both passive and actively-cooled systems on display in Zotac's suite at CES, one of the most interesting was a new fanless computer in a larger form-factor than previous C-series mini-PCs - and it's powered by an 6th-gen Intel Core i5 6300U processor.
“The ZBOX C Series returns with an Intel Skylake CPU while delivering the same silent performance in an all new ZBOX size. More processing power, more entertainment and more productivity is contained within. The new C Series also support USB 3.1 Type-C, perfect for connecting to new gadgets and more bandwidth.”
Here are the specifications:
- CPU: Intel Core i5-6300U processor (dual-core up to 3.0 GHz)
- GPU: Intel HD Graphics 520
- Storage: 1x 2.5-inch SATA 6.0 Gbps bay
- RAM: 2x DDR3L-1600 SoDIMM slots (up to 16GB supported)
- USB: 2x USB 3.1 Type-C, 2x USB 3.0, 1x USB 2.0
- Networking: Dual Gigabit LAN, 802.11ac wireless, Bluetooth 4.0
- Video output: DisplayPort, HDMI
Previous 'nano' systems in the C-series have offered VESA mounting, and this new system is no exception. A completely fanless system, this unit was quite heavy in hand but should pose no issue for most larger displays.
Networking includes dual Gigabit Ethernet ports and 802.11ac Wi-Fi
No specifics on pricing or release date just yet.

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.

The NVIDIA GeForce GTX 750 Ti is fast but also power efficient, enough-so that Ryan found it a worthwhile upgrade for cheap desktops with cheap power supplies that were never intended for discrete graphics. Of course, this recommendation is about making the best of what you got; better options probably exist if you are building a PC (or getting one built by a friend or a computer store).

Tom's Hardware went another route: make it fanless.
After wrecking a passively-cooled Radeon HD 7750, which is probably a crime in Texas, they clamped it on to the Maxwell-based GTX 750 Ti. While the cooler was designed for good airflow, they decided to leave it in a completely-enclosed case without fans. Under load, the card reached 80 C within about twenty minutes. The driver backed off performance slightly, 1-3% depending on your frame of reference, but was able to maintain that target temperature.
Now, if only it accepted SLi, this person might be happy.

Somewhere in the world, someone is developing a passively-cooled desktop made up of copper water pipes. Thirty-six (36) of them pass through what looks like an aluminum block attached to the socket LGA 1155 heatsink mount. As the copper pipes heat up, it passes to the air within it. Convection forces this to exhaust upward through the copper chimney and replaces it with cool air from below.
All Images, Credit: "Monster", CoolEnjoy.net Forums
From the 3D prototype, it looks like two passively-cooled discrete GPUs are intended to fit just above the elbow in the chimney. Even from the rendering, it is clear that quite a lot of thought and effort has gone into this project. I cannot tell how they intend to access PCIe slots from up there, be it a larger motherboard or an extension adapter, but options probably exist.
Initial testing with a Core i5-4440 (stock frequencies) show around 65 deg C at full CPU load. This should be in line with a typical air-based cooler.
Either way, this is the most impressive "SuperPipe" cooler that I have seen.
Your move, MSI.

Tagged: thermalright, hr-22, air cooling, heatsink, passive cooling
Additional photos have hit the Internet via Chip Hell of Thermalright’s upcoming HR-22 CPU cooler. The monstrous heatsink is the successor to the HR-02 with improvements to improve cooling and compatibility with tall memory DIMMs.
Thermalright has not released any formal specifications, but judging from the teaser photos the HR-22 pairs eight “U” shaped 6mm heatpipes with what appears to be a nickel plated copper base plate and an absolutely massive aluminum fin stack. The fin stack has notches along the sides and the heatpipes hold the cooler up high enough so as to not get in the way of memory modules with tall heat-spreaders. The fin stack itself is about as tall as a 140mm fan. Users can use the HR-22 as a passive heatsink or with a single 140mm fan that is attached via two retention clips on either side of the fan.
This cooler is going to be heavy and while it is rated to support LGA 2011 platforms, clearances may be tight depending on the particular motherboard and case used. There is no word on pricing or availability, but it should be available later this year. Pricing will definitely be on the high end for air coolers and approaching that of AIO liquid coolers such as the Corsair H100i.
In the mean time, more teaser photos (showing the HR-22 installed in a system) can be found over at TechPowerUp.
I am looking forward to seeing this cooler benchmarked!

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.

Tagged: trinity, silent pc, passive cooling, asus, APU, amd
AMD officially launched its desktop Trinity APUs (Accelerated Processing Units) today, and along with the new processors are a number of new socket FM2 motherboards to support them. One of the cooler motherboard and Trinity APU pairings was shown off today in a completely silent PC by ASUS and AMD in the Akihabara district of Tokyo, Japan.
The silent system is nested inside a Streacom FC5 chassis that does double duty as a case and heatsink for the AMD APU. Inside the system is an unidentified power supply, two DDR3 DIMMS, Corsair Force SSD, ASUS F2A85-M PRO motherboard, and – of course – the AMD A10-5700K APU that we recently reviewed.
The APU is covered by an aluminum and copper block that is then connected to the metal case via four heatpipes. Then, the outside of the case has a finned design to provide more cooling surface area (but likely just to make it look cooler, heh).
This passively cooled system would make for a really nice home theater PC case, and the GPU prowess of the Trinity APU is well suited to such a task. You can find more photos of the fan-less Trinity system over at FanlessTech.
What do you think of Trinity, and will you be using it in your next build?

Tagged: silentmaxx, passive cooling, hsf, cpu cooling, cooler
Having a silent system without fans is a noble goal, but CPUs generally need at least one. A new heatsink from Silentmaxx called the TwinBlock is designed to passively cool processors up to approximately 100W. Supporting sockets 774, 775, 1155, 1156, 1366 on the Intel side and 939, 940, and AMD 2/3 for AMD processors, it is compatible with just about any processor. The TwinBlock is, in a word, massive. Weighting in a just over 3 pounds, the heatsink measures 210mm (B) x 135mm (D) x 160mm (H) mm. It features a copper base with 10 heatpipes that connect to two aluminum fin arrays.
Interestingly, FanlessTech pointed us to a new computer build – the Fanless I-850 Gamer – that the company is planning to use the passive heatsink with to create a silent gaming PC. The PC can be equipped with up to an Intel Core i7-3960X Sandy Bridge-E processor and up to either an AMD 7970 or NVIDIA GTX 670 graphics card. The processor is cooled using the TwinBlock cooler while the GPUs are using custom coolers that should only kick on the fans over long gaming sessions or folding. The Fanless I-850 starts at 1279,00€ for the base configuration.
It is possible to buy just the heatsink, however. The Silentmaxx TwinBlock cooler can be yours for about $120 USD (€ 99.90 inc. VAT). More photos of the cooler are available below, and you can read more about the cooler on the SilentMaxx website.
