This morning, PC liquid cooling giant Swiftech announced that it will be withdrawing the H220 CPU Cooling Kit from US sales due to a conflict with a patent held by AseTek. Back on June 7, 2013, Swiftech's parent company, Rouchon Industries, received a letter from AseTek claiming that the H220 CPU Cooler infringed on US patents 8,240,362, and 8,245,764.
The letter demanded that Swiftech cease and desist all manufacturing, sales, and importation of the H220 CPU Cooler into the United States. The company says that on June 27, 2013 their counsel responded to AseTek stating that SwiftTech does not believe the H220 infringed on any patents held by AseTek. Swiftech says that they then asked AseTek if AseTek would be willing to offer a nonexclusive license for the asserted patents in an effort to avoid any unnecessary litigation.
On July 12, 2013, AseTek responded and stated that the company does not offer licenses on its patents. Swiftech says that it continues to firmly assert its position that it is not infringing on any patents but in an effort to avoid costly litigation, they have decided to pull the H220 CPU Cooling Kit from the US market. In a statement, the company had the following to say:
Given these circumstances, Swiftech wants to hereby reassure its US customers that: 1/ it will continue to provide full technical and warranty support for the H220 CPU cooling kits that have been sold in the US, and 2/ the product will continue to be sold in other countries.
Swiftech sincerely apologizes to its US customers for this extraordinary situation, the very first in its long history. For the past 15 years, Swiftech has been at the forefront of technological innovation in this industry, and it will continue to do so. In the words of Gabriel Rouchon, the company's Chairman and CTA: "I want our customers to know and expect with absolute confidence that Swiftech's resourcefulness will once again be brilliantly demonstrated in the immediate future".
Today, XSPC released a safety notice regarding its D5 Dual Bay Reservoir in regards to the top of the reservoir warping and allowing a tiny gap to open up. The company says that in most cases this warping will not cause a leak and is purely a visual issue, but there have been a few cases where it led to a very slow leak of coolant. XSPC says that it appears that this issue is only present in 2.5 percent of the first batch of reservoirs it shipped and is due to a flaw in the material used.
XSPC says that it believes the issue was caused by water temperatures beyond normal limits which caused the top plate to warp. The company says it has fixed the issues it had by changing the material used on the top plate and revising the mold. They have put the new model through rigorous testing which placed it far beyond normal usage temperatures and pressures and have found no further warping or leaks.
The revised design started shipping in April, so all current stock at resellers will already be version 2. If you have bought the product recently, it's likely you already have the revised model. The photos below show the difference between version 1 and 2. You can check the back of your reservoir against the photos above. If you see a leak from the highlighted area, you will need to get the reservoir replaced. If you are affected by this issue, please contact your local reseller to arrange a replacement, or contact technical support at firstname.lastname@example.org
Koolance unleashes EXC-800, a portable recirculating liquid chiller for PC liquid cooling enthusiasts
Koolance is at it again with another product launch this morning. The new EXC-800 Portable Recirculating Liquid Chiller is a water cooling enthusiast's dream featuring a rated 800W, or 2730 BTUs, an hour of cooling capacity. The chiller features Koolance's popular PMP-500 pump providing 42.9 gallons-per-minute of reliable flow of chilled liquid.
The chiller is able to adhere to one of four configurable temperature methods which includes an option to set the temperature to ambient to avoid condensation, or through the use of an external K-type thermocouple to chill the water to a desired temperature. The EXC-800 is capable of reporting the internal coolant flow rate, pump RPM, and condenser fan RPM which is displayed on a two-line organic LED display. The $1400 chiller is available at Koolance's website. (Source #1)
In the custom liquid cooled PC world, it is generally recognized as a bad idea to sandwich a radiator between two rows of fans. With most radiator designs, this actually creates a restriction of airflow as most radiator cooling fins are too tightly spaced for the fans to create a proper push-pull effect. Koolance recognized this problem and has designed three new radiators for its XC-Series that actually love being sandwiched between fans.
The new XC-Series Radiators come in three versions, the HX-120XC, HX-240XC, and HX-360XC, and feature a 2.1-inch thick copper core. They have a fin density of 30 fins-per-inch and are built around what is known as a Dual Pass design. This allows the use of high RPM fans in a push-pull configuration that actually increases airflow for added cooling ability.
The HX-120XC is a single radiator designed to fit a 120mm fan on each side, while the HX-240XC can fit two 120mm fans. Likewise, the HX-360XC can accommodate three 120mm fans on each side. MSRP is $49, $67, and $85 respectively.
BitFenix is known for its clean yet very modern chassis designs and today the company has unveiled its latest ATX masterpiece. The Ronin is a mid-tower PC case that features enhanced cooling capabilities, DIY/hacking-friendly features and styling, and the same high-quality construction that BitFenix is known for.
The Ronin accommodates up to two 140 mm fans in the top or a water cooling radiator up to 240 mm in length. Additionally, there are two 120 mm fan locations in the front and one in the back as well as one on the bottom. Like other modern PC chassis, BitFenix has designed the hard drive cages to be removable to allow the installation of graphics cards up to 420mm in length.
Continuing BitFenix's long-standing DIY-friendly design, the Ronin features tool-free drive locking mechanisms, a plethora of cable management options, as well as a motherboard tray CPU bracket cutout to allow easy swapping of CPU coolers. Air filters are located in the front of the case as well as on the bottom allowing for a mostly dust free lifespan. BitFenix says that the Ronin will be available in store shelves mid-July, but MSRP is unknown at this time.
Computex Taipei 2013 - While dashing through the halls I crossed paths with the Super Flower Leadex 1000W PSU. I noticed the PSU rather quickly but it wasn't until my second day at the hall till I snapped a couple of quick pics.
Super Flower makes very good power supplies, we often find them with other company's stickers on the case but we can always tell when we have a Super Flower. This model is has a unique feature that lights the power plugs at the base.
With the box on display as well this product can't be too far off. Time to search through my email and get a unit over to Zac for review.
Computex Taipei 2013 - Noctua had their maybe upcoming active noise cancellation (ANC) cooler back out at Comptuex this year. We say again because we had a taste of the technology last year at Computex but this year's version is much more refined. I would say it is pretty damn close to production ready actually but that's not to say anyone can afford it.
The first thing everyone is thinking has to be why Noctua would even make a product like this to begin with. The company makes silent coolers, I've hand nearly all of them and can honestly say I don't use anything else and the reason why is because they are quiet and work better than advertised.
What ANC gives the company is the ability to run its fans at higher RPMs and retain the silent operation that Noctua is known for. With more airflow, the coolers can dissipate more heat from the CPU, increasing the thermal capacity of the cooler. With overclocking making a comeback on Haswell even us old guys are ready to get back in the game.
Computex Taipei 2013 - Rosewill showed off some truly cool things at this year's Computex, but something that also caught our eye was their new digital PSU and a nice passively cooled power supply.
Starting with the Rosewill Epoch, their new digital PSU, which has a USB dongle on the back which shoots your information out to your PC, with the usual statistics like temperature, etc. The passively cooled PSU named "Silent Night" comes in both 500W and 600W flavors, and includes no fan. This is a great purchase for those who are wanting to keep the noise down in their new system. We should hopefully have some of these to review in the coming months.
Computex Taipei 2013 - I think all of us here at TweakTown are huge fans of the Prodigy, as we've used their case for many system builds and guides. Rosewill though, aren't as well known, but their Neutron case could change all of that.
The Neutron is a beautiful case with some unique features, such as the ability to install a huge PSU - something the Prodigy isn't capable of. There's a swivel HDD installation method, as you can see in the pictures below. There's lots of cooling options and watercooling is no problem for the Neutron, with the radiator capable of being installed at the top, or the front. Another unique feature is the ability to shift the USB and power buttons around, where Rosewill said it's as easy as undoing a few screws and shifting it around.
It's nice to see them thinking outside of the box, once more.
Computex Taipei 2013 - I went and took a look at the Rosewill booth, and as usual, I walked away impressed. First off, we had a look at their custom painted Throne case, which is better to just show on video, and pictures, both of which we have for you below.
Ok, now how good is that? Impressed? I was. It felt amazing to touch, looked even better to the eye, and is just beautiful. I don't know how practical it is, but Rosewill were attracting plenty of people to their booth with this beautiful specimen. Thanks Rosewill, for thinking outside of the square with this chassis.
