NVIDIA Offering Heroes of the Storm Video Card Bundle
The latest bundle from NVIDIA is based around the Heroes of the Storm MOBA from Blizzard and packages the Diablo character with a character skin exclusive to the bundle and a seven-day stimpack. The bundle will be available with qualifying GeForce GTX 950 or 960 cards. NVIDIA describes the cards as being "built for the ultimate MOBA experience" for gamers that prefer their MOBAs in the Blizzard game universe. Gamers will be able to further enhance their experience with the GeForce Experience, giving them the ability to "record, broadcast and stream your games to your friends and the world with just one click."

Thermaltake Announces New Pacific Radiators
Thermaltake is adding to its stable of water cooling products with the Pacific RL and R radiators, built with "high-quality German aerospace-grade materials and constructed with zinc, a powerful anti-corrosion agent." The Pacific RL is 50mm thick and uses a dual-row 13-set flat tube design to improve heat transfer. It will be available in lengths from 120mm to 560mm with the 120mm, 240mm, and 360mm available in white as well as black. The Pacific R uses the same dual-row tube design in a thickness under 50mm with lengths of 120mm, 180mm, 240mm, 360mm, and 540mm.

Tuning Graphite for Better Catalysts
Catalysts are very important materials as they make some nearly impossible chemical reactions possible. Typically though, the catalysts used in various devices on a day to day basis require rare and expensive materials like platinum. Finding ways to replicate these catalysts while reducing costs has been a major goal of many researchers, and now those at MIT and Berkeley Lab have created a new kind of catalyst that may just achieve that goal.
An essential ingredient for many chemical reactions is energy, and some reactions can require a lot of energy to convert the ingredients to the final products. What a catalyst does is add intermediary steps that require less energy to complete, and in the end the catalyst remains, ready for more reactions. By tuning the catalyst it is possible to improve its performance and make it more selective, but the kind of catalysts that can be tuned also tend to be fragile and difficult to process into a device. This is why the more durable, but rarer catalysts, like platinum, are used, but the MIT researchers have discovered how to make graphite into a tunable catalyst. What they have done is found a way to chemically alter the surface of the graphene sheets that make up graphite, in order to tune its properties.
As graphite is already a kind of universal electrode, producing it and adding it to devices is going to be easy and cheap. The chemistry the researchers used is also well understood and can be scaled up, making this a potentially ideal, tunable catalyst. Applications include converting carbon dioxide into fuels and fuel cells.

Hardware Roundup: Monday, September 21, 2015, Edition
A new week is upon us, with several items to help you kick it off right. There is a review of the SilverStone Raven RVZ02 case, a mini-ITX case that is smaller than the past one, but still capable of fitting a video card up to 13" long. We have a comparison of some different CPU water blocks for the Intel Haswell-E line, so you can see which one will give you the best cooling potential for your build. The Kingston HyperX FURY DDR4-2666 16GB Memory Kit gets tested to see what kind of performance you can expect from this on your Intel Z170 motherboard. Finally, the MEIZU M2 Note 4G LTE smartphone is reviewed to show that despite being a budget smartphone, this model still has plenty of impressive features.

Magnetic Insulator Used to Create Electric Circuit with Spin Waves
There is a good chance that in the future computers will rely on the spin of electrons to carry information, instead of their charge as is the current design. That transition is still far in the future though, as the required technologies are still being developed. Researchers at the University of Groningen, Utrecht University, the Université de Bretagne Occidentale and the FOM Foundation have recently created an electrical circuit that features a magnetic insulator and uses spin waves, which had been thought impossible before.
The reason it was believed impossible to use a magnetic insulator in an electrical circuit like this is because it would take far too much energy to generate the spin waves in the insulator. The researchers have gotten around this limitation though by carefully designing the geometry of the system and instead of generating a spin waves, utilizes those naturally present. The circuit consists of the magnetic insulator yttrium iron garnet (YIG) with platinum strips on both sides. When an electron in one strip strikes the YIB it creates a small disturbance in the spin waves already present from thermal fluctuations. Once the perturbation reaches the other platinum strip, the spin is passed onto an electron in the platinum, which influences the electron's motion, creating a measurable current.
Circuits transmitting information via spin waves could potentially be more efficient than current designs.
