Corsair's Hydro Series H50 closed-loop CPU cooler impressed us enough to score a 9/Kick Ass verdict last year and made it onto our Best of the Best list, and according to Corsair, its new H70 model blows it out of the water, so to speak.
"Thanks to the H70, you no longer need a fin array the size of a small shoebox to cool aggressively overclocked CPUs," stated John Beekley, VP of Technical marketing at Corsair. "The H70 stands toe-to-toe with any CPU cooler on the market, and does it with less noise, easier installation, and support for nearly every ATX-compatible case."
Corsair said the new H70 includes several upgrades over the H50, such as a double-thickness (50mm) radiator with higher heat-exchanging capacity, a more capable pump/cold plate unit, and a pair of 120mm speed-switchable fans.
The H70 is available now, though not a ton of online retailers have the item listed yet. Street price looks to be around $110.

Boutique system builder iBuyPower is bringing its portable LAN Warrior back into battle, this time equipping the mATX rig with a liquid cooling setup.
"LAN party gamers push their systems to the limits, making liquid cooling a necessity," said Darren Su, Vice President of iBuyPower. "The liquid cooled LAN Warrior II provides gamers with a way to keep their system safely overclocked without forcing them to haul around a full sized rig or sacrifice power."
Pricing starts at $750 for an AMD-based setup, $800 for an Intel P55 configuration, and $1,000 if stepping up to Intel's X58 platform. If you have the jingle, you can stuff up to two videocards into each one, including a pair of ATI HD 5970 graphics cards for quad-CrossFireX fun.
I’m debating switching to water-cooling. I was initially worried about maintenance or the unit leaking, but those issues seem to be a thing of the past. What happens, however, if the fan stops working on the radiator? Is the fan difficult to replace? Would you have to replace the entire unit? Anytime I see reviews or ads, they never specify whether the fan is replaceable or permanently attached to the radiator unit.
Taking a page from conventional refrigeration techniques, NEC has developed a new cooling system the company claims uses 60 percent less energy than a water cooling loop, and up to 80 percent less than an air cooling system.
NEC's cooler is built around a chlorofluorocarbon (CFC) substitute. The refrigerant starts to boil at around 50C, at which point it changes into vapor and absorbs the heat coming from the CPU. Like a traditional water cooling loop, it then flows through a tube and is cooled by a fan in a radiator before turning back into a liquid and starting the process anew.
In addition to low greenhouse effects, NEC says the cooling fan doesn't have to work nearly as hard when compared to other cooling systems, and so it uses less energy. Not only that, but NEC claims the system is around 70 percent cheaper to produce than other cooling mechanisms.
So when can you get one and slap it into your system? Not anytime soon. NEC plans to first use the cooler internally, and then market the design to data centers in 2011. When or if this ever trickles down into the mainstream market remains to be seen.

CoolIT is prepping it's Omni ALC cooler, a self-contained universal liquid cooling solution the company claims "provides aggressive heat dissipation for optimal graphics performance," and that includes Nvidia's Fermi architecture.
"When you pair the world's fastest GPU with the first-ever universal GPU liquid cooling solution, the results are visually astonishing," remarked Geoff Lyon, CEO of CoolIT Systems. "This combination will shatter benchmarks and deliver the most pulse-pounding graphics performance to date."
CoolIT says the Omni ALC represents a departure from traditional GPU cooling design, in that you'll no longer need to purchase an entirely new cooling solution for each generation of videocard. Instead, only the GPU-specific interposer plate will need to be changed.
The Omni ALC will ship this summer - no word yet on price.
In the pantheon of nerd achievement, water cooling ranks near the top—somewhere between installing Linux and becoming fluent in Klingon. And there’s a reason the hardest of the hardcore prefer water cooling: It’s incredibly effective at lowering the temperatures of core system components. With higher thermal conductivity and specific heat capacity than air coolers, water cooling can mean double-digit drops in CPU and GPU temperatures.
However, water cooling isn’t exactly a walk in the park. You’ve got two challenges ahead of yourself: Designing the water-cooling system that’s right for your PC, and actually putting it together. Both tasks will take some time and effort, but neither has to be daunting. Every first-time water-cooling build is a learn-as-you go experience, but we’ll walk you through the details and help you avoid the mistakes that would take the biggest toll on your system and your wallet.
The University of Illinois is about to become home to IBMs newest supercomputer, the Blue Waters. When it is finished in 2011, it will be the most powerful supercomputer allowing public access. With the aid of Big Blue’s new Power7 processors, the rig is expected to be capable of a staggering 16 petaflops. IBM did, however, clarify that initial peak performance is likely to be closer to 10 petaflops, with sustained real-world performance in the neighborhood of 1 petaflop.
IBM’s fears about overheating led them to develop a special water-cooling system for the whole rack, processor and all. This Power7 chip sounds like a nice way to play Crysis, right? You might be worried that this kind of power will be reserved just for wealthy governments and super villains. Well, luckily the Power7 will ship out in business servers sometime in 2010. Start saving those pennies.
CoolIT is somewhat notorious for enormous but effective closed water-cooling systems: its Boreas and Freezone Elite kick the pants off of conventional air coolers and are much more user-friendly than piecemeal water-cooling setups. Now CoolIT wants to bring self-contained water-cooling to the masses with the Domino Advanced Liquid Cooling.
The Domino eschews both the large heatsinks and the Peltier thermoelectric coolers of its predecessors in favor of a radiator and single 12cm fan, which gives the Domino less oomph than the Boreas or Freezone Elite, but confers several advantages to the water-cooling newb.
First, the Domino costs a cool $80, compared to $600-plus for the Boreas and $350 for the Freezone Elite. Second, the Domino is much smaller and easier to install; CoolIT boasts that an amateur with no CPU-cooling experience can install it in 10 minutes.
We may or may not recognize it, but fluid is a very integral part of our everyday lives. It decides everything from our fuel economy to (in some cases) how cool our computer runs. Until now, there was only one key way of deciphering the mechanics of fluids, and that was the Prandtl equation, developed in 1904. Sadly though, the Prandtl equation has many limitations, including only having the ability to calculate only two-dimensional problems, and a steady flow (such as that of a car traveling slowly). Thanks to a breakthrough by MIT’s George Haller, that’s all about to change.
A recently developed new equation, which is a product of four years of work by Professor Haller, will apply to three-dimensional and unsteady flows. This was confirmed with the aid of Thomas Peacock, the Atlantic Richfield Career Development Associate Professor at MIT, who lead experiments in order to validate the equation. Professor Peacock states, “This is the tip of the iceberg, but we’ve shown that this theory works.” The new work will probably go down as one of the greatest scientific advances of the decade, if it survives the peer review that will come.
This innovation in the mechanics of liquids will have an overwhelming influence on many industries, including aerospace, automotive and even computers. With these breakthroughs in calculating how liquids will act and perform in different environments, there’s no doubt that your PC’s liquid cooling system will soon get an overhaul.
