CRYORIG Releases Official Statement Regarding Skylake PCB Concerns

Intel’s Skylake architecture is built on the 14nm manufacturing process and utilizes a thinner structure compared to previous generations which can make the chip flex under high pressure air coolers. When we originally covered this story,  there was some confusion about what high pressure actually refers to. Any flex or damage to Skylake CPUs is caused by hefty mounting hardware which pushes down onto the CPU with high pressure. It does not refer to liquid cooling with a high pressure pump. Nevertheless, this is a worrying development and seems to occur when a system is transported with the CPU cooler attached. As you might expect, manufacturers including Noctua, Rajintek, be quiet and more all conform to Intel’s recommendations. The latest company to clarify their position is CRYORIG, who sent a fairly length statement explaining the root cause and preventative measures they take:

“We at CRYORIG have the following information and statement to make, regarding the recent news and discussion regarding damaged PCB’s on Skylake CPU’s, which many in the industry believe is caused by abnormal heatsink mounting pressure during transportation of the PC system. First of all we want to assure users of CRYORIG products that currently no CRYORIG heatsinks have displayed this problem, either through media reports, third party sales channels or internal testing. CRYORIG heatsinks are fully compatible with socket 1151 processors, and follow specifications set forth by CPU manufacturers. But as a note of precaution we suggest users to lay their PC system flat (with the heatsink in a vertical position) whenever they are transporting their PC system.

Based on the information and testing reports we currently have at hand, although CRYORIG’s own products did not show this problem, we have derived the following suggestions and insight into the Skylake PCB damage problem. From our observation the cause of the bent/damaged PCB is caused by the combination of two factors.

A) High mounting pressure from the CPU heatsink mounting system, with no flexibility in the system.
B) Increased directional force created by the weight of the heatsink and movement of the PC chassis.

In the cases that have been reported by media, it holds true that these issues have only been observed in “Pre-Built” systems. These systems have the heatsink installed before shipping, which are subjective to both point A+B. Thus if a heatsink already has high mounting pressure with no system of flexibility, heavy weight and is tossed around during shipping, then the force of the heatsink is possible to bend at the softest point. In this case the softest point is the Skylake PCB.

What makes CRYORIG heatsinks safe?

In our own product line we have two different mounting systems. First is the MultiSeg on our heavier products, then there is the X-Bar and MultiSeg Light. The MultiSeg Quick Mount System uses a sturdy Medium Carbon Steel backplate. We chose the Medium Carbon Steel for it’s high tensile strength, which protects the mainboard from bending when using heavier heatsinks like the R1 or H5. In combination with a highly rigid backplate, the spring screw system is what provides the downwards-clamping mounting force. This combination of a tough frame and a relatively softer point of flexibility is the key to why CRYORIG products are not seen damaging the CPU PCB. When extra vector/directional force is exhibited on the heatsink (such as during transport), the softest point in the system always gives. In this case the spring screws will deform to absorb the extra external force, much like a suspension system.

In our lighter products, the X-Bar and MultiSeg Light mounting systems omit the rigid steel backplate for a 30% Fiber Glass PBT. The lighter weight of our H7/M9 and C7 heatsinks creates less stress on the mainboard, which is why the steel backplate is not needed. Also, using a Fiber Glass filled PBT has multiple benefits.

Material Modulus of Elasticity (The Higher the more Rigid)

  • 30% Fiber Glass PBT 15.0 GPa Max
  • Medium Carbon Steel 213.0 GPa Max

The Modulus of Elasticity for 30% Fiber Glass PBT is 15.0 GPa, while Medium Carbon Steel is 213 GPa. The combination of structural support and elasticity, allows these backplate system to still have a point of flexibility when extra force is exerted. The lighter weight of the product itself also makes it safer when directional force is exhibited.

In all, although caution should always be exhibited when transporting delicate electronics, we want our consumers to feel safe about their CRYORIG product. Our finely tuned mounting kits are safe to use. Moreover, stationary PC’s do not have anything to worry about either.”

This is a very detailed and reassuring statement which helps to understand how the flexing process can occur. According to the research so far, all failures have occurred during transportation. As a result, it is recommend to remove the CPU cooler, or lay the system flat when moving the system.

NZXT Releases FX-140 V2 Cooling Fans Designed for Radiators

One of the hardest parts of building your own systems is the decision on what fans to get for it. While a lot might go for the default ones provided with whatever chassis you purchase, it might not be to everyone’s liking. Especially the liquid coolers want just the best of the best and NZXT has quite a bit of experience in that area.

NZXT has had quite a lot of experience with their Kraken series All-in-one liquid coolers and the latest series of X41 and X61 coolers have blown most competitors out of the way and they’ve grabbed a lot of rewards from reviewers as well. One of the things that make these coolers so good is the attached fan, the NZXT FX140V2 and just that type of fan can now be yours for any setup you want as they’re being released on their own.

 

The FX V2 series is a complete redesign of the previous generation pressure fan series and it creates effective and high airflow under the most restrictive environments. The fan is controlled by a pulse width modulation (PWM) that can be controlled by either your motherboard, fan controller, or NZXT CAM software. The FX140V2 has a max rotation speed of 2000RPM and allows for a much more gradual increase of speed over traditional voltage control.

High speed and lot of noise isn’t always what you’re looking for and the NZXT FX140V2 has you covered here too, still performing great at 800RPM and limiting the sound level to 20dB.

The NZXT FX V2 140mm fan will be available for purchase at retailers and e-tailers for £17.99 / €19.99 in June.

Fractal Design Launched Venturi Series High Pressure and High Flow Fans

Fractal Design launched their newest line of fans with the Venturi Series. The new fans come with built-in rubber vibration dampening corners and are ideal for high pressure or high airflow usage with low noise output.

The HF-12 and HF-14 Venturi High Flow Series fans are optimized for low-restriction airflow environments and for uses such as case fans and other low-restriction usage scenarios. The fans are designed with a variety of performance increasing and noise-reducing features.

The HF-14 also comes with two sets of solid vibration-dampening rubber corners: one for standard 140mm fan hole spacing (125mm) and one compatible with the standard 120mm hole spacing (105 mm).

Venturi High Flow Key Features

  • Featuring true FDB-bearings, providing silent operation coupled with a long lifespan
  • Equipped with a counter-balancing magnet in the hub that reduces the axial tension on the bearing, further protecting the longevity of the bearing
  • Dense, sturdy construction, made from high-grade glass fiber reinforced thermoplastic polymer with fan geometry that is optimized for a good balance between static pressure and maximum airflow, resulting in good performance in all usage scenarios
  • Aerodynamically shaped thin stator struts (including wire strut), mimicking the design commonly found on airplane wings, delivering correct angles allowing for air to easily pass through reducing noise and unwanted turbulence.
  • Stator struts are angled perpendicular to the blades, helping to reduce noise commonly emitted when the blades pass the struts. In effect, minimal noise that may be emitted will be constant and therefore almost inaudible to the ear.
  • Strategically placed notches near the fan hub on the trailing edge of the blades, further reducing and diffusing humming noise produced when the blades pass the stator struts
  • Includes a “trip wire” on the rear side of the blades, near the leading edge. The trip wire technology, also commonly found in airplane wing designs, introduces a microturbulent layer that helps to combat the elements that negatively affect performance. The presence of the trip wire overall provides a more efficient and quiet fan environment.
  • Delivers high precision due to high-grade materials used, permitting the distance between the blades and frame to be as small as 1.2mm, contributing to a higher performance fan
  • Featuring a powerful motor to maintain a reliable speed
  • Comes with a low-speed adapter, for reducing the speed without the use of a fan controller
  • Includes vibration-dampening corners, from solid high-quality synthetic rubber on the fans
  • 140mm fans come with an additional set of vibration-dampening corners are included that lends compatibility with 120mm fan mounts (105mm screw spacing). This enables the use of 140mm fans on many CPU coolers.
  • Screws pass through the rubber only, not through plastic, therefore eliminating the chance of noise derived from rattling when in use
  • Available in 120mm and 140mm fan sizes

The HP-12 and HP-14 Venturi High-Pressure Series PWM fans are optimized for high-restriction airflow scenarios, making them an excellent choice for usage on large heatsinks, on radiators, or in other highly restrictive scenarios. The HP series otherwise has the same great features as the HF series apart from the different usage scenario, including the adjustable corners.

Venturi High-Pressure PWM Key Features

  • Featuring true FDB-bearings, providing silent operation coupled with a long lifespan
  • Equipped with a counter pull magnet, that reduces the axial tension on the bearing
  • Optimized fan geometry as a high-pressure fan, delivering high-performance results in high restriction usage scenarios, such as in use with large heatsinks or water cooling radiators.
  • Dense, sturdy construction, made from high-grade glass fiber reinforced thermoplastic polymer
  • Featuring PWM control with a very wide speed range, starting at only 400RPM (400 +/- 100 RPM), ideal for CPU heatsinks or radiators, where the motherboard can control the fan speed based on the CPU temperature.
  • Aerodynamically shaped thin stator struts (including wire strut), mimicking the design commonly found on airplane wings, delivering correct angles allowing for air to easily pass through reducing noise and unwanted turbulence.
  • Stator struts are angled perpendicular to the blades, helping to reduce noise commonly emitted when the blades pass the struts. In effect, minimal noise that may be emitted will be constant and therefore almost inaudible to the ear.
  • Strategically placed notches near the fan hub on the trailing edge of the blades, further reducing and diffusing humming noise produced when the blades pass the stator struts
  • Includes a “trip wire” on the rear side of the blades, near the leading edge. The trip wire technology, also commonly found in airplane wing designs, introduces a micro-turbulent layer that helps to combat the elements that negatively affect performance. The presence of the trip wire overall provides a more efficient and quiet fan environment.
  • Delivers high precision due to high grade materials used, permitting the distance between the blades and frame to be as small as 1.2mm, contributing to a higher performance fan
  • Featuring a powerful motor to maintain a reliable speed
  • Comes with a 1->2 PWM signal splitter wire, for connecting additional fans to a single PWM header on your motherboard or PWM fan controller
  • Including vibration-dampening corners, from solid high-quality synthetic rubber on the fans
  • 140mm fans come with an additional set of vibration-dampening corners are included that lends compatibility with 120mm fan mounts (105mm screw spacing). This enables the use of 140mm fans on many CPU coolers.
  • Screws pass through the rubber only, not through plastic, therefore eliminating the chance of noise derived from rattling when in use
  • Available in 120mm and 140mm fan sizes

EK-Vardar Fans for Radiator Use Starts Shipping

It’s been about 3 weeks since EK Water Blocks introduced us to their first line of complete in-house developed fans, the EK-Vardar series, and now they’re available. The new fans are the result of a years worth of research and testing, picking just the right parts and generating the right layout to push as much air through radiators as possible with as little resistance as possible.

The fans get the name Vardar from the type of the cold northwesterly wind blowing from the mountains down to the valleys of Macedonia. It is a type of ravine wind, enhanced by a channeling effect while blowing down through the Moravia-Vardar gap, bringing cold conditions from the north to the Thessaloniki area of Greece. A fitting name for these fans.

These 120mm fans are available in 5 versions, the EK-Vardar with 1150rpm, 1450rpm, 180rpm, or 2200rpm and the EK-Furious Vardar with 3000rpm. The sound levels variate depending on model, but start at 23.7dBA maximum for the slowest and 42dBA for the Furious Vardar.

The Vardar series is using a 7-fin fan blade design and has a sealed-edge fan casing to prevent loss of airflow. The motor is double ball bearing with a lifespan of 50.000 hours and comes with PWM support.

Available now, the fans all come with an MSRP of €14.95 including VAT, except the Furious version that will set you back €16.95.

EK Announces Vardar Series 120mm Fans Designed for Radiator Use

Not all fans are equal and there are many that aren’t really suited well use with radiators. So who better to create a fan for just this scenario than EK Water Blocks. And they have done just that with the new high-pressure 120mm EK-Varder fan that is the first in-house engineered fan from EK.

The simple design should allow for integration into almost any system that can handle a little black, though that isn’t the only colour available. It’s announced in single and two-tone colours with a monochrome fan sticker.

The task at hand was to create a fan with high static pressure  while keeping a low noise profile. EK used a 7-fin fan blade design and the motor windings are actively cooled, double ball bearing and rated for 50,000 hours. An important factor for radiator cooling is a sealed edge so the air doesn’t escape out the side instead of being forced through the fins. EK created just that with the old-school looking, but effective, black square shape.

The EK-Vardar 120mm cooling fan currently consists of five models, four regular and one Furious Vardar with the latter built-in distinctive all-black design. All fans come with four self-tapping screws and are pre-sleeved (F1-F4: black, FF5: red) for your convenience. The new fans will be available for purchase in the first half of January 2015, although a limited quantity will be available in mid-December 2014.

Phantek Release MP Series Fans for Radiator Use

Phanteks has announced the immediate availability of the PH-F120MP and PHF140MP Series High Static Pressure fans. The new MP Series fans are designed specifically for radiators where they have the ability to overcome the airflow restriction caused by high fin density. They new fans will be available in 120mm and 140mm sizes as the name suggests.

The redesigned seven blade fans use the Maelström Vortex Booster (MVB2) technology. The precisely angled blades generate a silent and controlled airflow with a downdraft vortex allowing for a greater amount of air to pass through and reduce the airflow turbulence at the same time. They also use the Updraft Floating Balance bearing (UFB) that further increases the lifespan and reduces mechanical noise.

The MP Series’ PWM functions allow users to adjust the speed from 500 to 1600 RPM on the PH-F140MP and 500 to 1800 RPM on the PH-F120MP. Higher speed for performance and lower for silent operation. Maximum airflow for the 140mm is 68.1 CFM with a static pressure of 1.62mm H20 while the maximum noise is 25.3 dBa. The 120mm can push 53.3CFM at a static pressure of 1.72mm and has a maximum noise of 25 dBa.

The black and white Phanteks MP fans have an MTBF of over 150,000 hours and come with a 5-year warranty.
