Introduction: Rethinking the Stock Cooler

AMD's Wraith cooler was introduced at CES this January, and has been available with select processors from AMD for a few months. We've now had a chance to put one of these impressive-looking CPU coolers through its paces on the test bench to see how much it improves on the previous model, and see if aftermarket cooling is necessary with AMD's flagship parts anymore.

While a switch in the bundled stock cooler might not seem very compelling, the fact that AMD has put effort into improving this aspect of their retail CPU offering is notable. AMD processors already present a great value relative to Intel's offerings for gaming and desktop productivity, but the stock coolers have to this point warranted a replacement.

Intel went the other direction with the current generation of enthusiast processors, as CPUs such as my Core i5-6600k no longer ship with a cooler of any kind. If AMD has upgraded the stock CPU cooler to the point that it now cools efficiently without significant noise, this will save buyers a little more cash when planning an upgrade, which is always a good thing.

A quick search for "Wraith" on Amazon yields retail-box products like the A10-7890K APU, and the FX-8370 CPU; options which have generally required an aftermarket cooler for the highest performance. In this review we’ll take a close look at the results with the previous cooler and the Wraith, and throw in results from the most popular aftermarket cooler of them all; the Cooler Master Hyper 212 EVO.

Scythe's Fuma cooler, stocky and quiet but not ready for overclocking contests

Subject: Cases and Cooling | July 20, 2016 - 04:12 PM |
Tagged: scythe, fuma, heatsink

Scythe's Fuma heatsink is a fair size at 137x149x130mm with a weight of 920g, including the two 120mm fans, though shorter than many on the market.  That stock design could cause some problems if your RAM has impressively sized heatsinks but for most modules you should not have any issues and it does not impinge on your first PCIe slot.  In the tests Modders-Inc performed reasonably well when cooling an i7-4770k at stock speeds, unfortunately an overclock of 4.4GHz did see the cooler struggle and the CPU frequency was throttled back almost immediately.  For lesser loads the low RPM fans will be able to keep your temperatures reasonable and do so without creating much noise.  If you have a midranged CPU and want a quiet cooler in the $55 range, drop by to check out the full review.

"Heatsink designs are driven by the fundamental principle that a larger surface area equates to better heat dissipation than a smaller area. Factoring in componential consent, modern aftermarket CPU tower heatsinks had to get creative to compensate and dial-in the efficiency needed, hence the rise of dual-tower cooler designs"

Tagged: thermalright, quiet computing, Le Grande Macho, heatsink, cpu cooler, air cooling, air cooler

Thermalright has released a very large new CPU air cooler with an equally impressive name: Le Grande Macho RT.

01.jpg

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.

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.

Introduction and First Impressions

DEEPCOOL's Gabriel is part of their Gamer Storm series of products, and this low-profile design is rated up to 95 W to keep the latest processors cool under load. So how does it perform? We'll take a close look at the performance of this mini-ITX inspired air cooler in today's review.

There are so many inexpensive options for air cooling on the market that it's almost overwhelming. At the top of the list in popularity are low-cost tower coolers from Cooler Master, with the ubiquitous Hyper 212 Evo at around $30, and the slightly smaller Hyper T4 at $25. But with a height of 159 mm for the 212 Evo and 152.3 mm for the T4 these coolers are not going to fit in every situation - and certainly not in a slim enclosure. There are plenty of low-profile CPU coolers on the market, one of the lowest being the Noctua NH-L9i, a $40-ish cooler which stands just 37 mm tall (with the fan!), but the tan and reddish-brown color scheme isn't for everyone, and the ultra-low profile design (which is also limited to a 92 mm fan) won't be required for many builds.

So when I began looking for a low-profile air cooler for my own use recently one of the options that cought my eye was this Gabriel, part of DEEPCOOL's Gamer Storm line.  The Gabriel had the advantage of being just $34.99 on Newegg when I picked it up, making it less expensive (and less tan and brown) than the Noctua. At 60 mm tall with its 120 mm fan installed, the Gabriel should fit in most low-profile enclosures, considering even half-height expansion cards are a bit taller at about 69 mm. The Gabriel also offers an understated look with a grey (well, mostly grey) fan. Of course appearances mean nothing unless it's well made and cools effectively, and for myself the question became, is this going to rival the experience of a Noctua (long my preferred brand) CPU cooler?

The CRYORIG H5 heatsink comes with some new features

Subject: Cases and Cooling | September 17, 2015 - 02:34 PM |
Tagged: CRYORIG, H5 Universal, heatsink, Hive Fin

The CRYORIG H5 is referred to as Universal as it supports LGA sockets going back to 775 and all AM2/3 or FM2 AMD sockets, significantly more breadth that most coolers on the market.  At 110.9x143x168.3mm (4.4x5.6x6.6") it may not fit in every case and the 920g with the fan installed is going to need a sturdy board to support it.  [H]ard|OCP tested out the effectiveness of the Hive Fin and Jet Fin features in their review.  As it turns out the cooler is not the most effective choice but it is one of the quietest and for the price it is recommended for users that won't be heavily overclocking their CPU.

"The CRYORIG H5 UNIVERSAL heatsink claims to have a Hive Fin Design for Extreme Performance Efficiency and is compatible with a huge number of older and modern AMD and Intel processors. Along with the Hive Fins, we get Jet Fin Acceleration and Turbulence Reduction. Let's however see just how well it cools your CPU."

Cooler Master Hyper 612 Ver. 2 Heatsink Released

Subject: Cases and Cooling | October 2, 2014 - 05:25 PM |
Tagged: hyper 612, heatsink, fanless, cooler master, cooler

The Cooler Master Hyper 612 Ver. 2 CPU cooler is a member of their "Hyper Series", upper-mainstream product lineup. It looks to be one of the (if not the) biggest offerings in that category. Its extreme dimensions are 139mm (5.47") in length by 102mm (4.02") wide, with a height of 160.4mm (6.32"). It has a 120mm fan which basically takes up a whole side and slowly blows air across it. Some sites claim that it can be used fanless with some (but not every) CPU.

coolermaster-612ver2.jpg

Cooler Master is particularly proud of their "Continuous Direct Contact" technology. In other words, the heat pipes are flattened into a contact with the CPU's heatspreader (or die guard for people like Morry). This eliminates a reservoir of heat before the copper pipes can carry it to the aluminum fins and out into the air.

The heatsink is now available, but no pricing information yet (I cannot find it online).

Fanless, SFF or heavy weights, check out the best in quiet coolers

Silent PC Review has just done a major update to their lists of the best Big, Small and Fanless coolers, both air and water.  The Big list requires a fair sized case in which to contain the cooler and consists of those coolers which operate at 20 dBA or less from 1m away with no more than 45°C rise over ambient.  The graph starts with the loudest 20dBA and grows more quiet with the measured temperature appearing at the noise level they tested, those with multiple values have adjustable speeds.  The Small list has the same setup but consists of coolers that should fit in most SFF cases and the fanless lacks noise ratings for obvious reasons.  Check them all out here.
