Antec Kühler H20 650 Review

Antec Kühler H20 650 Review

Manufacturer: Antec
UK price (as reviewed):
£54.99
US price (as reviewed): $69.99

If you’ve got around £50 to spend on a CPU cooler, then you’ve got quite a decision on your hands. There are dozens of great examples – both air and liquid-cooled to choose from and most of these will fit into your average enthusiast case too. Decisions aren’t based just on cooling performance either; there’s also noise to consider and in some cases colours and bling too as we saw with the Phanteks PH-TC14PE.

Of course, all-in-one liquid coolers are still very much in the limelight and if we had the option, they’re probably where our money would go. They top our cooling graphs and many cost less than some of the large premium air coolers out there too. We recently looked at Antec’s Kühler H20 950, which received awards for both our test systems thanks to great cooling, excellent software control and easy mounting. However, if £60 is your limit but you still want to delve into liquid cooling, then Antec has a slightly cheaper option.

The Kühler H20 650 is essentially a half height radiator, single fan-version of the Kühler H20 950 and retails for a more modest £55, which is one of the cheapest all-in-one liquid coolers we’ve seen. It still features the combined fan and pump assembly as its bigger brother as well as the directional blades at the rear to focus airflow.

Thermal paste is pre-applied and there’s the same mounting mechanism employed as the Kühler H20 950 too with a ring locking onto the cooler and securing using thumb screws with a backplate used on LGA115X and AMD systems. There’s surprisingly few bits to contend with but that’s exactly the way it should be, especially with an all-in-one liquid cooler.

The radiator as we’ve already mentioned is a half height model but while it won’t be able to keep up with full size examples like the larger Kühler H20 950, we’ve found they’re not far off in cooling terms and take up less space too. The contact plate and waterblock, being minus a pump, is very low profile indeed so this is one of the more compact all-in-one liquid coolers we’ve tested. The single fan is actually controlled using an on-board temperature monitor rather than tapping into the motherboard’s fan signals, with the temperature also feeding into an illuminated plate on top of the waterblock, which changes colour.

When we looked in the box, we assumed there were two fans, however, the extra fan-shaped contraption is a standoff, which Antec claims reduces resistance at the rear of the radiator between it and the case, improving airflow. The extra screws provided can of course be used to mount an extra fan too. Sadly, one thing that is missing is software control – there’s no way to manually control the fan so you’re left at the mercy of the integrated firmware dishing out fan speeds based on the temperature.

Halo composer fired from Bungie

Halo composer fired from Bungie

Martin O’Donnell was responsible for the score in several Bungie games and had been working with the company since before it was bought by Microsoft in 1999.


Halo and Destiny composer Martin O’Donnell has seemingly been fired from Bungie.

Having previously been the studio’s audio director, O’Donnell revealed over Twitter that the company’s board of directors had let him go last week for no reason.

’I’m saddened to say that Bungie’s board of directors terminated me without cause on April 11, 2014,’ said O’Donnell.

A statement on Bungie’s site contrasts slightly with O’Donnell’s comments and instead states ’today, as friends, we say goodbye,’ and goes on to wish him luck on future endeavours.

He had worked on the scores for several of Bungie’s projects, including older titles Myth 2 and Oni and Halo: Combat Evolved. He was also working on the score for the studio’s upcoming title Destiny, collaborating with former Beatle Paul McCartney. The score is planned as a full release of its own under the title Music of the Spheres.

As well as composing scores, O’Donnell was also responsible for a lot of the general sound work and for directing voice talent in several of Bungie’s games.

O’Donnell had been working with the company since before it was bought out by Microsoft in 1999, originally working on a contract basis out of his own company, TotalAudio.

Intel Q1 financials show data centre growth

Intel Q1 financials show data centre growth

Intel’s Q1 2014 results slightly exceeded analysts’ expectations, but the company’s mobile arm is suffering a significant drop in revenue.


Intel has released its financials for the first quarter of 2014, and things are looking good with better-than-expected results despite its continued struggles to break into the mobile arena and a still-shrinking desktop market.

The company’s official figures for the quarter show $12.8 billion in revenue, exactly matching analysts’ expectations, with a gross profit margin of 59.7 per cent for a total earnings per share of $0.38 – above the $0.37 average expected by analysts. $3.1 billion of this came from the Data Centre Group, responsible for server and high-performance computing (HPC) products, which enjoyed a bumper 11 per cent boost in revenue over the same period last year; the PC Client Group, which targets the still-shrinking PC market, brought in the lion’s share at $7.9 billion, a one per cent drop compared to Q1 2013.

In the first quarter we saw solid growth in the data centre, signs of improvement in the PC business, and we shipped five million tablet processors, making strong progress on our goal of 40 million tablets for 2014,‘ claimed Intel’s chief executive Brian Krzanich during the company’s earnings call. ‘Additionally, we demonstrated our further commitment to grow in the enterprise with a strategic technology and business collaborationwith Cloudera, we introduced our second-generation LTE platform with CAT6 and other advanced features, and we shipped our first Quark products for the Internet of Things.

Other highlights include a 10 per cent quarter-on-quarter drop in revenue for the Internet of Things Group which ended the quarter with $482 million in revenue, still an 11 per cent improvement over the same period last year thanks largely to new low-power Atom and Quark processor products. The company’s Mobile and Communications Group, responsible for smartphone and tablet oriented chips, was by far the biggest loser: with just $156 million in revenue, its income was down 52 per cent quarter-on-quarter and a massive 61 per cent compared to Q1 2013.

Investors seem pleased with Intel’s performance in the quarter, with the company’s share price rising 1.08 per cent in pre-market trading to $27.06, still short of its recent April 2012 high of $28.38.

LaCie customers hit by data breach

LaCie customers hit by data breach

Storage specialist LaCie has warned customers of a data breach which has resulted in ne’er-do-wells making off with usernames, passwords and credit card details.


Storage specialist LaCie has warned customers of a major data breach that may have compromised their personal data used for purchases between March 2013 and 2014.

The hole in the company’s servers is not, it has been quick to reassure customers, indicative of the security of its storage products in general; no customer data stored on the company’s cloud services or network-connected storage devices is thought to be involved in the breach. Rather, the attack targeted the company’s ecommerce system, making off with transaction information for purchases made in the last year.

On March 19, 2014, the FBI informed LaCie that it found indications that an unauthorised person used malware to gain access to information from customer transactions that were made through LaCie’s website,‘ the company explained to customers in a statement made nearly a month after it was alerted to the breach. ‘We believe that transactions made between March 27, 2013 and March 10, 2014 were affected. The information that may have been accessed by the unauthorised person may include customers’ names, addresses, email addresses, and payment card numbers and card expiration dates. Customers’ LaCie website user names and passwords could also have been accessed, which is why we required a reset of all passwords.

LaCie has not confirmed how the data was stored; while credit card information should be encrypted, password are better stored as salted one-way hashes which become much harder for an attacker to crack. Either way, those with LaCie accounts are advised to change their passwords, both on the LaCie service itself and anywhere else where the same or similar password was used, and to keep a close eye on their credit card statements for unauthorised activity.

As a precaution, we have temporarily disabled the ecommerce portion of the LaCie website while we transition to a provider that specialises in secure payment processing services,‘ the company added. ‘We will resume accepting online orders once we have completed the transition.

Google pledges January launch for Project Ara

Google pledges January launch for Project Ara

Google’s Project Ara, created by one-time subsidiary Motorola and based on Dave Hakkens’ Phonebloks concept, is scheduled to hit the market in January 2015.


Advertising giant Google has confirmed that it is forging ahead with the Project Ara modular smartphone concept, and plans to release the first commercially available parts in January 2015.

Originally developed by Motorola Mobility based on concept work carried out by Dave Hakkens under the name Phonebloks, Project Ara was acquired by Google when it picked up the Mobility division from Motorola. Although the company would go on to sell the bulk of Motorola Mobility to Lenovo it kept hold of Project Ara, announcing in February this year commercialisation plans for the technology.

Project Ara aims to offer the same level of customisation available in the PC world to the smartphone – and, eventually, tablet, markets. The Ara platform uses a central chassis dubbed an Endo, to which component modules are connected via magnets. These modules contain everything from the display to the processor, storage, camera and battery, and can be assembled in almost any combination or pattern. As well as ending the annual phone upgrade cycle – the Endo itself, Google claims, would be good for five to six years – by offering the chance of incremental upgrades, the system would also allow for complete customisation: one Endo may have a high-end processor and high-spec camera, while another opts for a slower processor, no camera and a bigger battery for longer runtime.

Google held its first Project Ara developers’ conference this week, and CNET reports that it offered a timeline to commercialisation: the first Project Ara Endo will be on sale, barring any major setbacks along the way, in January next year for just $50. It will be joined by a range of component modules, although the specification and pricing for these has not yet been confirmed.

Google also outlined fabrication hardware for the modules themselves, developed in conjunction with academic and business partners and taking the form of large-scale 3D printers capable of working with conductive materials. More details on these will be provided at the next conference in July.

Noctua NH-U12S Review

Noctua NH-U12S Review

Manufacturer: Noctua
UK price (as reviewed):
£47.99
US price (as reviewed): $69.99

When all-in-one coolers started hitting the cooling scene a few years ago, you’d be forgiven for thinking it was the end of the road for premium air coolers. Noctua is one of the most established and recognised brands out there in the enthusiast scene, but even we have to admit that value hasn’t always been one of the company’s strong points. In the face of a growing number of super-cheap and capable coolers such as Deepcool’s GAMMAXX S40, you might think paying more than £30 for a CPU cooler isn’t worth it considering how well the latter performs for just £20.

*Noctua NH-U12S Review Noctua NH-U12S Review *Noctua NH-U12S Review Noctua NH-U12S Review
At £47.99, the NH-U12S isn’t even a humongous air cooler and you get a much smaller bit of kit than it’s larger sibling, the NH-D14, which retails for just £10 more. However, the NH-U12S isn’t about raw cooling. With a maximum rated noise of just over 22db(A) and even less using the included low noise adaptor, this is a cooler for those where noise reduction is just as important as a chilly CPU.

*Noctua NH-U12S Review Noctua NH-U12S Review *Noctua NH-U12S Review Noctua NH-U12S Review
Part of the reason for the NF-F12′s high price is the NF-F12 PWM Focused Flow 120mm fan included in the box. This retails for £17 on its own – one of the most expensive fans on the market. There’s a whole raft of technical blurb in this fan’s specifications but the long and short of it boils down to Noctua claiming it produces a better quality noise by utilising many of these swanky features such as a focused flow frame, varying angular distance and vortec-control notches, plus better airflow and cooling.

The heatsink itself is up to Noctua’s usual standards, however, if you haven’t seen one of the Austria-designed cooler’s in person before, that’s essentially the same as saying build quality is epic. Crammed into this diminutive cooler, which measures just 158mm tall and 125mm wide, are five heatpipes built into a compact array of aluminium fins, plus a copper contact plate that sports a nickel plating.

*Noctua NH-U12S Review Noctua NH-U12S Review *Noctua NH-U12S Review Noctua NH-U12S Review
Even the packing is a labour of love, with everything packed into premium-feeling cardboard boxes that are all exactly the right size to take up precisely 100 per cent of the outer box. It’s not often we feel compelled to make this sort of comment but it’s totally justified here. As such, with everything labelled for each socket, despite the above average amount of mounting components, installation is fairly painless.

The fan clips are second only to SilverStone’s latest coolers such as the AR01 , in terms of ease of use – no spindly, awkward things here, which is just as well as you need to fit the single 120mm fan after you’ve mounted the cooler to the motherboard.

*Noctua NH-U12S Review Noctua NH-U12S Review *Noctua NH-U12S Review Noctua NH-U12S Review
Also included are all the fittings needed to mount a second fan, including the brown antivibration corner pads plus a low noise adaptor that can drop the maximum rpm from 1,500 to 1,200, slotting in between the 3-pin power feed and the standard PWM fan cable. Everything you need is included in the box, including an extra-long screwdriver to reach the mounting screws.

MSI Shows Z97 Motherboards Including Mini-ITX

MSI Shows Z97 Motherboards Including Mini-ITX

MSI looks set to continue its support for mini-ITX when Intel’s Z97 chipset arrives


Following a leak that showed images of future products, MSI has released a few previously locked-down images of its new range of motherboards.

We’re assuming they sport Intel’s anticipated Z97 chipset, which still uses LGA1150 CPUs, and is set for launch this summer.

As we reported here, there will be several ‘Gaming-series’ motherboards, but the images show Gaming 3, Gaming 5, Gaming 7 and Gaming 9 name titles in addition to a mini-ITX board.

Many of the boards feature 802.11ac WiFi adaptors, with the mini-ITX board sporting what appears to be a custom, integrated adaptor on the I/O panel, rather than a standard slot on the PCB.

The Gaming 9 model looks like quite a beast, with an imposing red and black colour scheme and we also spotted an M.2 expansion slot between the two lower 16x PCI-E slots along with voltage measuring points near the on-board power button.

The Gaming 3, Gaming 5 and Gaming 7 also offer the M.2 expansion slot, which suggests this will be a familiar feature on Z97 boards, although it appears to be absent from the funky-looking mini-ITX model.

What do you make of MSI’s new line-up? Let us know in the forum.

Attenborough working on a documentary for the Oculus Rift

Attenborough working on a documentary for the Oculus Rift

Attenborough is reprising his work with production company Atlantic to create a nature documentary for the Oculus Rift.


Beloved nature documentary veteran Sir David Attenborough has announced that he is working on a project for the Oculus Rift.

Conquest of the Skies is currently being filmed for the virtual reality headset in Borneo’s jungles using an eight-camera setup to produce a full 360 degree experience. It is being produced by a joint venture between production company Atlantic and broadcaster Sky.

Attenborough, best known for his documentaries aired through the BBC, has worked with Atlantic before with nature programs that have been filmed in 3D.

Production company Atlantic has already acquired several Oculus Rift development kits and the company’s commercial director John Morris told Realscreen that he considers this new virtual reality technology as being ‘a new platform you can monetize’ and predicts that millions of the headsets will be sold.

Morris also added that the company is excited by the fact that there are no rules of convention around what a non-fiction experience on the Oculus Rift should be like, comparing this phase of virtual reality to the beginning of cinema. This will be one of the first non-gaming productions to be considered for the Rift.

Oculus VR has achieved a significant level of mainstream recognition outside of the gaming industry thanks to Facebook acquiring the company for $2 billion last month. Facebook founder Mark Zuckerberg explained that he sees the technology as having massive potential for the future of communication beyond its gaming capabilities.

Quantenna promises 10Gb/s Wi-Fi in 2015

Quantenna promises 10Gb/s Wi-Fi in 2015

Quantenna’s existing MU-MIMO chipset can be found in Asus’ newest router, but its success next year promises up to 10Gb/s of bandwidth via 802.11ac’s MU-MIMO technology.


Wireless communications specialist Quantenna has announced the development of a Wi-Fi chipset capable of ten gigabit per second (10Gb/s) throughput, with plans to release it commercially next year.

Perhaps the biggest complaint regarding Wi-Fi – aside from alleged health implications, disproved by scientific rigour – is that its performance can lag behind that of a wired connection. Even if you’re right next to an access point, the actual throughput of a 1.3Gb/s 802.11n Wi-Fi link is usually well below that of a 1Gb/s wired Ethernet connection – and the further away you travel from the access point, the slower it gets. Said bandwidth is also shared between all users; if you’re on a heavily-congested access point, you can expect the performance of your connection to drop significantly.

Quantenna is hoping to resolve this problem by giving wireless connections significantly more headroom, starting with a 10Gb/s chipset based on the 802.11ac standard which improves support for Multi-User Multiple-Input Multiple-Output (MU-MIMO) connectivity. Extending the existing MIMO technology, which uses multiple antennas to isolate signals and reject noise, MU-MIMO allows for multiple connections to individual client devices which are no longer competing for the same bandwidth. The result: significantly improved performance and reliability.

Quantenna’s 8×8 architecture with adaptive beamforming demonstrates that the ‘massive MIMO’ promise of significantly higher throughput, robustness, and reduced interference can be realised in practice,‘ claimed Andrea Goldsmith, Stephen Harris Professor of Electrical Engineering at Stanford University, in support of the company’s work. ‘This architecture will also significantly enhance the capabilities of MU-MIMO, allowing it to support interference-free transmission to many more devices simultaneously. These technology advances will transform the landscape of applications and devices that Wi-Fi can support.

Quantenna’s MU-MIMO chipset is already used in Asus’ latest Wi-Fi router, but the version due for release in 2015 will be considerably improved. ‘Wi-Fi is no longer a convenience,‘ claimed Quantenna chief executive Sam Heidari at the announcement. ‘People expect it to ‘just work’ even with demanding applications like HD video streaming. With Quantenna’s 10G Wi-Fi, they’ll always get the performance they expect—even as their expectations continue to rise.

The company’s existing chipset, which supports 4×4 MU-MIMO antenna configurations, will be extended in 2015 to support 8×8 MU-MIMO setups offering a total aggregate throughput of 10Gb/s. How much such a feature will add on to the cost of commercially available routers and access points that choose to implement it, however, has not been announced.

Amazon says no to Bitcoin

Amazon says no to Bitcoin

Amazon’s head of payments Tom Taylor has said that the company has no plans to add support for Bitcoins to its webshop, despite rivals doing exactly that.


Amazon has indicated that it’s not going to join in the cryptocurrency revolution by adding support for Bitcoin to its payment system, even as increasing numbers of its competitors do exactly that.

Bitcoin, created by the pseudonymous Satoshi Nakamoto in 2008, is a distributed, decentralised cryptocurrency based on proof-of-work principles: set your computer generating SHA256 hashes for transaction validation and you’ll get rewarded with Bitcoins of your very own, generated at an ever-decreasing rate by the algorithm itself. The cryptocurrency is free from governmental control, anonymous yet entirely traceable – until you attempt to convert Bitcoins into fiat currency or vice-versa, of course – and runs on a decentralised system of volunteer computers.

It sounds remarkable, but Bitcoin’s meteoric rise from being worth fractions of a penny to a high of more than $1,000 per coin has been fraught with difficulties. Amateur coding errors in major Bitcoin exchanges like MT Gox – originally set up to be a trading site for Magic: The Gathering cards, hence the name – has led to the loss of millions of dollars in Bitcoins and a significant drop in their value on the open market. For every country like the US which is making its laws more Bitcoin-friendly, there are countries like China which have banned the use of the cryptocurrency outright.

In the UK and US, increasing numbers of retailers are accepting payment in Bitcoin – largely out of a hope that it will continue its rise in value, recover from the recent slump and make yesterday’s £50 payment double in value or more. Amazon, however, has said it won’t be joining the revolution. ‘Obviously, it [Bitcoin] gets a lot of press and we have considered it,‘ Tom Taylor, head of Amazon’s payments arm, told Re/code in a recent interview, ‘but we’re not hearing from customers that it’s right for them and don’t have any plans within Amazon to engage Bitcoin.

At the time of writing, a single Bitcoin was valued at just shy of £300 – a significant dip from its high of more than £600 before the recent crash.
