PC Gamer Hardware (formerly Maximum PC) spotted a cool immersion cooling system being shown off at the SuperComputing conference in Denver, Colorado earlier this month. Allied Control who was recently acquired by BitFury (popular for its Bitcoin mining ASICs) was at the show with a two phase immersion cooling system that takes advantage of 3M's Novec fluid and a water cooled condesor coil to submerge and cool high end and densely packed hardware with no moving parts and no pesky oil residue.
Nick Knupffer (@Nick_Knupffer) posted a video (embedded below) of the cooling system in action cooling a high end processor and five graphics cards. The components are submerged in a non-flamable, non-conductive fluid that has a very low boiling point of 41°C. Interestingly, the heatsinks and fans are removed allowing for direct contact between the fluid and the chips (in this case there is a copper baseplate on the CPU but bare ASICs can also be cooled). When the hardware is in use, heat is transfered to the liquid which begins to boil off from a liquid to a vapor / gaseous state. The vapor rises to the surface and hits a condensor coil (which can be water cooled) that cools the gas until it turns back into a liquid and falls back into the tank. The company has previously shown off an overclocked 20 GPU (250W) plus dual Xeon system that was able to run flat out (The GPUs at 120% TDP) running deep learning as well as mining Z-Cash when not working on HPC projects while keeping all the hardware well under thermal limits and not throttling. Cnet also spotted a 10 GPU system being shown off at Computex (warning autoplay video ad!).
According to 3M, two phase immersion cooling is extremely efficient (many times more than air or even water) and can enable up to 95% lower energy cooling costs versus conventional air cooling. Further, hardware can be packed much more tightly with up to 100kW/square meter versus 10kW/sq. m with air meaning immersion cooled hardware can take up to 10% less floor space and the heat produced can be reclaimed for datacenter building heating or other processes.

Neat stuff for sure even if it is still out of the range of home gaming PCs and mining rigs for now! Speaking of mining BitFury plans to cool a massive 40+ MW ASIC mining farm in the Republic of Georgia using an Allied Control designed immersion cooling system (see links below)!

You might remember mention of the Thermaltake 900 Vertical Super Tower on the podcast last night, if not it should be posted soon so you can catch up. This plus-sized tower was designed to give watercooling fanatics enough space to fit in whatever they can dream up and [H]ard|OCP received one for review. The design proved to be unfriendly for self contained watercoolers which have a two fan radiator, only single fan rads will fit in the front portion of the case. For the more serious, this case can contain up to three full enthusiast class radiators, 240, 280, 360, 480 or 540mm rads can be accommodated. The sheer size of the case makes installation convenient for those who will build a system worthy of this case. [H]ard|OCP gave this a gold, and offered some interesting modding suggestions on their conclusion page; check it out here.
"It's a tower and it's super! Thermaltake's new Tower 900 is not close to your typical PC computer enclosure. It is built for a very specific customer; the enthusiast that wants plenty of room to do highly customized build and then have the ability to easily show it off is the target demographic for this chassis."
Here are some more Cases & Cooling reviews from around the web:

- Cooler Master MasterBox 5t Review @ OCC
- Cooler Master MasterCase Maker 5T @ Benchmark Reviews
- Cooler Master Masterbox 5t @ eTeknix
- Corsair's Carbide Series Air 740 @ The Tech Report

Introduction and First Impressions
The GENOME is the world’s first computer case with an integrated liquid-cooling system, and this unique design allows users to simply drop in the main system components and have a complete system with liquid cooling loop (and with very little effort).
“One of the first things many of us look at when considering the purchase of a new case is whether it will accommodate the cooling subsystem that we’d like to install in our next build. Can you install big enough radiators? Is there room in the main interior space for the reservoir and pump that you have your eye on? How will it look when everything is put together? To improve PC user experience is why DEEPCOOL comes up with GENOME, which is a PC hardware component, consists of an ATX PC case and an extreme liquid cooling system.”
When I first heard about the GENOME I was nonplussed - wondering how I would even go about reviewing at since it defies conventional classification. It’s as much a CPU cooler as a case, and DEEPCOOL calls this simply a “cooling system”. But however you label it there is no doubt that this novel concept has the potential to produce a polished build with a minimal effort (if it is well-designed, of course).
If you have switched cases as often as I do (no one should - I do it once every week or two), you might appreciate any sort of labor-saving design in a case. As a reviewer moving a test system from one enclosure to the next, I just want an easy build with adequate clearance and good cable management (these requirements are true for most normal people as well). Some cases are much easier to build in that others, and I was very curious to see how something which sounds quite complex would actually come together.

Thermaltake is readying the Tower 900 for launch later this month. Clad in all-black or snow white, the Tower 900 was designed in concert with Watermod France to be modder and liquid cooling friendly with a design that allows enthusiasts to show off their DIY builds.
The upcoming Tower 900 series is part of Thermaltake’s TT Premium line and is constructed using a “dismantlable module design” that allows builder to completely strip the case down to the frame to make modding the various panels and pants easier. The case used a neat dual chamber design that puts the PC components front and center and the liquid cooling, power supply, and storage devices behind the motherboard chamber.
The front chamber is surrounded on three sides by 5mm thick tempered glass and holds up to E-ATX motherboards vertically and supports 260mm high CPU coolers and 400mm long graphics cards. There are 8 PCI expansion slots. In addition to the motherboard, the front chamber holds two 3.5”/2.5" drive trays that are visible through the case windows, two hidden 2.5" SSD mounts, and up to two large coolant reservoirs. Thermaltake suggests that the Tower 900 would work well with dual loop systems, and I tend to agree. Modders will be able to put together some very nice looking builds, especially if they use rigid tubing.
Other features include large rounded case feet, a single 5.25” drive bay nestled in the bottom of the front panel, and four USB 3.0 and one audio jack for front panel I/O up top.
Around back, the Tower 900 hosts a standard ATX power supply, up to four 3.5” or 2.5” drives in a hard drive cage (though you give up some radiator capacity on the right side if you use the HDD cage), and up to an impressive 480mm or 560mm (depending on if its 120mm or 140mm fans) radiator on both the left and right sides! In theory you could have a 560mm radiator for your multi GPU setup on one loop and 360mm radiator for the CPU on a second loop along with all four hard drives or if you can get by with the two 2.5” drives in the front chamber your CPU could also have a 480/560mm radiator of its own.
If you are into air cooling, the Tower 900 supports a total of 13 120mm or 140mm fans. One fan in the front chamber above the SSD drive trays, four on the left, four and four on the right in the back chamber, and two fans each on the top and bottom.
For those curious, the case measures 29.6” x 16.7” x 19” and weighs 54 pounds. Once it is full of water and PC components, you should probably team lift this monster heh. Additional photos and videos can be found here.
It certainly looks nice, and I can see a lot of potential for custom PCs. I am looking forward to seeing the full reviews as well as what enthusiasts are able to do with it!

Computer Base (German language, Google-translated link here) has rounded up five CPU water blocks to see which might offer the highest performance on their Intel Core i7 3960X-equipped testbed.
Image credit: Computer Base
The tested water blocks include:
- Alphacool NexXxos XP3 Light V.2
- Phobya UC-2 LT
- Raijintek CWB-C1
- Heatkiller IV Pro Pure Copper
- XSPC Raystorm Pro
The review offers an thorough look at the design of each water block, as well as an interesting look at the effects of flow-rate on performance:
"The test has been shown that with increasing flow rate decreases the temperature difference of the water before and after heat sinks. However, the question arises whether a higher flow also has a positive effect on the cooling performance itself. A negative effect of increasing flow as well: Most pumps are unthrottled very loud to work, so that a reduced pump capacity is useful for a silent water cooling."

While AMD's latest dual-GPU powerhouse comes with a rather beefy-looking liquid cooling system out of the box, the team at EK Water Blocks have nonetheless created their own full-cover block for the Pro Duo, which is now available in a pair of versions.
"Radeon™ has done it again by creating the fastest gaming card in the world. Improving over the Radeon™ R9 295 X2, the Radeon Pro Duo card is faster and uses the 3rd generation GCN architecture featuring asynchronous shaders enables the latest DirectX™ 12 and Vulkan™ titles to deliver amazing 4K and VR gaming experiences. And now EK Water Blocks made sure, the owners can get the best possible liquid cooling solution for the card as well!"
Nickel version (top), Acetal+Nickel version (bottom)
The blocks include a single-slot I/O bracket, which will allow the Pro Duo to fit in many more systems (and allow even more of them to be installed per motherboard!).
"EK-FC Radeon Pro Duo water block features EK unique central inlet split-flow cooling engine with a micro fin design for best possible cooling performance of both GPU cores. The block design also allows flawless operation with reversed water flow without adversely affecting the cooling performance. Moreover, such design offers great hydraulic performance, allowing this product to be used in liquid cooling systems using weaker water pumps.
The base is made of nickel-plated electrolytic copper while the top is made of quality POM Acetal or acrylic (depending on the variant). Screw-in brass standoffs are pre-installed and allow for safe installation procedure."
Suggested pricing is set at 155.95€ for the blocks (approx. $177 US), and they are "readily available for purchase through EK Webshop and Partner Reseller Network".

Tagged: water cooling, overclocking, liquid cooling, EKWB
The guys over at the Tech Report spotted a rather shiny product coming out soon from EKWB. The company is adding a nickel plated memory heat-spreader kit can be used to replace your existing heatspreaders and hook into a RAM waterblock like EKWB's own Monarch X2 to allow you to liquid cool your memory and add it to your custom cooling loop.
These new modules are similar to the existing black modules, but have a nickel plated finish that is particularly shiny (see the photo below). Each kit includes the parts to replace the heatspreaders on two memory modules. Thermal pads are used to facilitate heat transfer from the memory chips to the CNC'ed aluminum heatsinks.
Users can then screw a memory waterblock (EKWB specifies the Monarch X2 Acetel/Nickel) to the top of the replaced memory heat-spreaders. Heat is then transferred from the heatsinks to the block and finally to the water loop.
The new Monarch modules are available now for $34.99. The Monarch X2 waterblock adapter is a further $38.99 if you want to water cool the DRAM. Note that the existing black anodized heatsinks are a bit cheaper at $29.99.
The heatsinks certainly look nice, and while I can see reasons to liquid cool them for aesthetics or to play around with extreme overclocking water cooling your memory using them will get expensive in short order considering you need to buy both kits for every two memory DIMMs (I hope you don't have X99 with all slots populated heh).
If you really want to cool all the things and add a bit of 'bling' to your system look no further!

ZOTAC is teasing a new mini PC "ready for virtual reality" leading up to Cebit 2016, happening later this month. The ZBOX MAGNUS EN980 supplants the EN970 as the most powerful version of ZOTAC's gaming mini systems, and will come equipped with no less than an NVIDIA GeForce GTX 980.
(Image via Guru3D)
Some questions remain ahead of a more formal announcemnent, and foremost among them is the version of the system's GTX 980. Is this the full desktop variant, or the GTX 980m? It seems to be the former, if we can read into the "factory-installed water-cooling solution", especially if that pertains to the GPU. In any case this will easily be the most powerful mini-PC ZOTAC has released, as even the current MAGNUS EN970 doesn't actually ship with a GTX 970 as the name would imply; rather, a GTX 960 handles discrete graphics duties according to the specs.
The MAGNUS EN980's GTX 980 GPU - mobile or not - will make this a formidable gaming system, paired as it is with a 6th-gen Intel Skylake CPU (the specific model was not mentioned in the press release; the current high-end EN970 with dicrete graphics uses the Intel Core i5-5200U). Other details include support for up to four displays via HDMI and DisplayPort, USB 3.0 and 3.1 Type-C inputs, and built-in 802.11ac wireless.
We'll have to wait until Cebit (which runs from March 14 - 18) for more details. Full press release after the break.
