Answering a customer question on Facebook, a Thermalright representative responded (translated):

"For all AMD fans, we have good news. As we advance AMD has assured the new AM4 processors and motherboards are put on the usual base-fixing, which is standard for AM2. To follow all the Thermalright coolers are used on the Zen processors without additional accessories!"

This news is hardly surprising considering AMD has used the same format for some time, much as Intel's current CPUs still work with coolers designed for LGA 1156.

The Le Grande Macho RT features no fewer than 7 heat pipes from its massive heatsink, and is paired with a quiet 140 mm fan (model TY-147B) that ranges from just 300 RPM to 1300 RPM. While large it is still smaller than the company's well-respected SilverArrow dual-tower cooler, and depending on performance could offer a compelling alternative for low-noise air cooling.

Introduction and First Impressions

The CRYORIG C7 is a compact air cooler for Intel and processors, designed to fit anywhere a stock solution will. Standing just 47 mm tall, and featuring a footprint close in size to an Intel stock cooler, CRYORIG claims this ultra-compact design will still outperform the stock solution.

c7_01.jpg

An attractive design, the C7 is further sweetened by a $29.99 retail, which places it in a favorable position in the compact CPU cooler market. Designs like these are rarely useful for enthusiasts, but there it certainly a need for good aftermarket options when overclocking isn't a consideration. There was a time when the stock Intel cooler was sufficient for many basic builds, and for some that may still be the case. But if you've spent a little more to get higher performance, a better heatsink can certainly help; and if you're an enthusiast, the stock cooler was never adequate anyway (even before Intel stopped shipping it in K series CPUs).

In this review we'll find out if this small cooler can deliver on its performance promise, and see just how much noise it might make in the process.

Manufacturer: Scythe

Introduction and First Impressions

The Scythe Ninja 4 (SCNJ-4000) is the latest model in the Ninja series, and an imposing air cooler with dimensions similar to Noctua's massive NH-D14. But there's more to the story than size, as this is engineered for silence above all else. Read on to see just how quiet it is, and of course how well it's able to cope with CPU loads.

NINJA4-Side_View.jpg

"The Ninja 4 is the latest model in the Ninja CPU Cooler Series, developed for uncompromising performance. It features the new T-M.A.P.S technology, an optimized alignment of heatpipes, and the back-plate based Hyper Precision Mounting System (H.P.M.S) for firm mounting and easy installation procedure. These improvements and a special, adjustable Glide Stream 120mm PWM fan result in an increased cooling performance while reducing the weight compared to his predecessor. Also the design of the heat-sink allows fan mounting on all four sides. This enables the optimal integration of the Ninja 4 in the air flow of the pc-case and reduces turbulence and the emergence of hotspots."

The Ninja 4 is built around a very large, square heatsink, which allows the single 120 mm fan to be mounted on any side, and this PWM fan offers three speed settings to further control noise. And noise is really what the Ninja is all about, with some really low minimum speeds possible on what is a very quiet Scythe fan to begin with.

NINJA4-Frontview.jpg

Will a single low-speed fan design affect the ability to keep a CPU cool under stress? Will the Ninja 4's fan spin up and become less quiet under full load? These questions will soon be answered.

CES 2016: AMD Announces Wraith Cooler

AMD seems to be starting off 2016 right. This is the year that they intend to switch to the Zen microarchitecture, and hopefully reclaim a profitable CPU market-share. While that's later in the year, they showed off a new stock cooler that will be bundled with upcoming processors. We don't have a press release or announcement for it, but they did publish a video to their Red Team fan community and they discussed it with attendees of the show.

amd-2016-newcpucooler-0106161228_HDR.jpg

The new cooler, called the Wraith, is significantly larger than their previous stock heatsink. It is rated at 125W, up from the previous offering's 95W. This dissipation wattage might allow some overclocking room, depending on the chosen TDP at launch, while providing lower noise at stock voltage and frequency. The fan is now constant speed, so it shouldn't whine under load. It might have also allowed them to tune the fan for its RPM, too.

Speaking of lower noise, the aforementioned video shows a dramatic reduction in that area. We're force to trust their recording and frequency-distribution graph. If accurate, the noise appears to be much lower and the energy is spread out over many frequencies.

No clue when it will launch, though.

Thermaltake Water 3.0 Riing RGB 240 and 360 Announced

Subject: Cases and Cooling | December 8, 2015 - 07:01 AM |
Tagged: water cooling, water cooler, thermaltake, cpu cooler

Thermaltake has announced the Water 3.0 Riing RGB, which is a water cooler with multi-color LEDs. Two SKUs will be available, which differ in radiator size. As the title of this post suggests, your choice will be between double-wide (240mm) and triple-wide (360mm) radiators. The lights surround the fan in a ring, and can be modified by a remote into a few different settings. Thermaltake notes that these settings persist after a reboot. I would think that's expected, but the wording sounds like a subtle reference to something. Over my head regardless.

thermaltake-2015-riing-360.jpg

I should note that there appears to be a typo in Thermaltake's specification sheet. On the Water 3.0 Riing RGB 360, it claims that its dimensions are 326x120x27mm. 326mm is the same length as its rubber tubing and, to say the least, it seems very unlikely that they intend to fit three, 120mm fans (360mm total) into a length that's 326mm long (plus fit the hosing off one side). The 240 model is listed as being 270mm long, which leaves 30mm for spacing and tubing, and that seems about right. I assume that they accidentally wrote the tube length as the radiator length. I have attempted to contact Thermaltake PR for clarification. I'll update the post if I get through and receive a response. This should be fine for most users looking to install a triple-wide radiator, but you should hold off if a few centimeters make or break your build.

No pricing or availability has been released yet.

Intel Skylake Processors Can Bend Under Pressure, Damage CPU and LGA Socket

Subject: Processors | December 4, 2015 - 11:35 PM |
Tagged: Skylake, Intel, heatsink, damage, cpu cooler, Core i7 6700K, Core i7 6600K, bend, 6th generation, 3rd party

Some Intel 6th-gen "Skylake" processors have been damaged by the heatsink mounts of 3rd-party CPU coolers according to a report that began with pcgameshardware.de and has since made its rounds throughout PC hardware media (including the sourced Ars Technica article).

IMG_8244.JPG

The highly-referenced pcgameshardware.de image of a bent Skylake CPU

The problem is easy enough to explain, as Skylake has a notably thinner construction compared to earlier generations of Intel CPUs, and if enough pressure is exerted against these new processors the green substrate can bend, causing damage not only to the CPU but the pins in the LGA 1151 socket as well.

The only way to prevent the possibility of a bend is avoid overtightening the heatsink, but considering most compatible coolers on the market were designed for Haswell and earlier generations of Intel CPU this leaves users to guess what pressure might be adequate without potentially bending the CPU.

Intel has commented on the issue:

"The design specifications and guidelines for the 6th Gen Intel Core processor using the LGA 1151 socket are unchanged from previous generations and are available for partners and 3rd party manufacturers. Intel can’t comment on 3rdparty designs or their adherence to the recommended design specifications. For questions about a specific cooling product we must defer to the manufacturer."

It's worth noting that while Intel states that their "guidelines for the 6th Gen Intel Core processor using the LGA 1151 socket are unchanged from previous generations", it is specifically a change in substrate thickness that has caused the concerns. The problem is not limited to any specific brands, but certainly will be more of an issue for heatsink mounts that can exert a tremendous amount of pressure.

From the Ars report:

"Noctua, EK Water Blocks, Scythe, Arctic, Thermaltake, and Thermalright, commenting to Games Hardware about the issue, suggested that damage from overly high mounting pressure is most likely to occur during shipping or relocation of a system. Some are recommending that the CPU cooler be removed altogether before a system is shipped."

Scythe has been the first vendor to offer a solution to the issue, releasing this statement on their support website:

"Japanese cooling expert Scythe announces a change of the mounting system for Skylake / Socket 1151 on several coolers of its portfolio. All coolers are compatible with Skylake sockets in general, but bear the possibility of damage to CPU and motherboard in some cases where the PC is exposed to strong shocks (e.g. during shipping or relocation).This problem particularly involves only coolers which will mounted with the H.P.M.S. mounting system. To prevent this, the mounting pressure has been reduced by an adjustment of the screw set. Of course, Scythe is going to ship a the new set of screws to every customer completely free of charge! To apply for the free screw set, please send your request via e-mail to support@scythe.com or use the contact form on our website."

As owner of an Intel Skylake i5-6600K, which I have been testing with an assortment of CPU coolers for upcoming reviews, I can report that my processor appears to be free of any obvious damage. I am particularly careful about pressure when attaching a heatsink, but there have been a couple (including the above mentioned Scythe HPMS mounting system) that could easily have been tightened far beyond what was needed for a proper connection.

We will continue to monitor this situation and update as more vendors offer their response to the issue.

Corsair Launches the H5 SF Mini-ITX CPU Liquid Cooler

Subject: Cases and Cooling | December 3, 2015 - 04:38 PM |
Tagged: water cooler, SFF, mini-itx, liquid CPU cooler, H5SF, cpu cooler, Corsair H5 SF, corsair

Corsair has launched the ultra-compact liquid cooler from their Bulldog chassis as a standalone product, and it's a unique solution for mini-ITX CPU cooling.

HG5-SF_06.jpg

Originally announced at this year's Computex as part of the Bulldog DIY system, this low-profile liquid cooler is designed to allow users of some of the smallest mini-ITX systems to not only keep their CPU's cool, but even allows some serious overclocking with up to 150 W of thermal dissipation. The design uses a blower-style fan that pushes air accross a compact radiator, and the entire unit is only 84 mm high for use in spaces that wouldn't ordinarily be able to support a powerful CPU cooler.

Corsair provides this chart comparing performance against SFF air coolers

From Corsair:

"Further expanding Corsair’s best-selling Hydro series line of liquid CPU coolers, the H5 SF is Corsair’s first liquid cooler designed specifically to meet the thermal demands of small form factor PCs. Easy to install and just 84mm tall, the H5 SF is compact enough to fit inside the most confined PC case, yet still offers up to 150W of heat dissipation, enough to cool today’s demanding high-end CPUs with overclocking headroom to spare.

The all-new design fits directly on top of any Mini-ITX motherboard with no need to attach the H5 SF to any external fan mounts or brackets, maximizing compatibility across a wide range of Mini-ITX and small form factor cases. A high-performance copper cold plate efficiently draws heat away from the CPU, where it’s then transferred into the integrated 120mm x 40mm radiator and exhausted by the H5 SF’s low-noise tuned 120mm blower fan. What’s more, the H5 SF’s blower fan also draws air over other heat producing motherboard components such as VRMs and chipset heatsinks, helping to keep your whole system cool.

Fully compatible with Corsair’s Obsidian Series 250D, Carbide Series Air 240, and Graphite Series 380T cases, the H5 SF is also critical to Corsair’s upcoming Bulldog chassis, allowing the new case to deliver low-noise, 4K living room gaming without compromising CPU choice. Now enthusiasts can take advantage of Bulldog’s H5 SF cooling for themselves and fit even the most demanding of CPUs, into the smallest of cases."

HG5-SF_08.jpg

The mounting system is unique, with a bracket that attaches inline with the screws securing the mini-ITX motherboard, requiring no additional contact with the enclosure. It's a clever idea that permits the installation of this liquid solution wherever an air cooler of up to 84 mm is possible.

Here are the specifications from Corsair:

  • Socket Support: AMD: AM2, AM3, FM1, FM2, Intel LGA: 115X, 1366
  • Cold Plate Material: Copper
  • Radiator Material: Aluminum
  • Radiator dimensions: 167mm x 40mm x 57mm
  • Total cooler height: 84mm
  • Fan dimensions: 120mm x 32mm
  • Fan speed: 1000 - 1800 RPM
  • Fan airflow: 12 - 24 CFM
  • Fan pressure: 2.5 - 8.3 mmH2O
  • Fan noise level: 36 - 42 dB(A)
  • Tubing: Low-Permeability Tubing
  • Warranty: Five years

HG5-SF_04.jpg

The H5 SF carries an MSRP of $79.99, and this cost (which is in keeping with Corsair's existing 120 mm pricing) seems pretty reasonable considering the unique implementation and thermal capability. Available starting today, the H5 SF is already listed for sale on Newegg.com for the $79.99 MSRP.
