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?

Noctua is a well respected manufacturer in the highly competitive CPU cooler space, offering products optimized for high efficiency and low-noise. The newest members of their S series coolers, the NH-D15S and NH-C14S, are based on known designs tweaked for maximum compatibility to ensure proper fit on your hot new Haswell, Haswell-E, or Skylake supported motherboard. Both coolers come standard with Noctua's SecuFirm2™ mounting mechanism, ensuring a secure mount between the cooler and CPU.

The NH-D15S CPU cooler is a dual tower cooler with a single fan sandwiched between the two radiator towers. The unit can support a maximum of three fans, but may suffer compatibility issues with certain motherboards when used outside of its default single-fan configuration. Noctua designed the cooler with their typical hybrid approach, combining a copper base plate and heat pipes with aluminum finned cooling towers. The base plate and heat pipes are nickel-plated for looks and to prevent corrosion. At an MSRP of $89.99, the Noctua NH-D15S comes with a premium price to match is colossal size.

The NH-C14S CPU cooler is single radiator cooler in a horizontal orientation with a single fan. The radiator's horizontal orientation gives the cooler a lower height in comparison to a cooler with the traditional veritical radiators while maintaining equivalent cooling performance. In typical Noctua fashion, the NH-C14S combines a copper base plate and heat pipes with aluminum finned cooling towers for an optimal hybrid cooling solution. The base plate and heat pipes are nickel-plated for looks and to prevent corrosion. The NH-C14S also retails at an MSRP of $89.99.

CRYORIG Announces A-Series Hybrid Liquid CPU Coolers

Subject: Cases and Cooling | November 4, 2015 - 03:24 PM |

CRYORIG has a new take on the venerable closed-loop liquid CPU cooler, addressing concerns about the temps of surrounding components on the board by including a reversible fan which mounts to the CPU block.


“The CRYORIG’s A40/A40 Ultimate and A80 HLC units are built on the base of Asetek’s 5th Generation Pump and CPU Cold Block technology with a small but obvious twist. With an additional adjustable and detachable Airflow fan, the CRYORIG A Series HLC is capable of lowering the temperatures of the components surrounding the CPU by up to 20%.”

There are three models in the series, with a standard 240 mm width A40, the A40 Ultimate which features a thicker 1.5-inch radiator (38.5 mm vs. 27.5 mm), and the 280 mm A80.

The company has released this slick video to demonstrate the difference this additional fan makes:

It’s an interesting concept and certainly any airflow over motherboard components it better than none, though I am slightly worried about increased noise from the 70 mm pump-mounted fan providing the hybrid cooling.

The new coolers are being released in Japan on November 5, with “mid-to-late November” promised for worldwide availability.

New Components, New Approach


After 20 or so enclosure reviews over the past year and a half and some pretty inconsistent test hardware along the way, I decided to adopt a standardized test bench for all reviews going forward. Makes sense, right? Turns out choosing the best components for a cases and cooling test system was a lot more difficult than I expected going in, as special consideration had to be made for everything from form-factor to noise and heat levels.

Along with the new components I will also be changing the approach to future reviews by expanding the scope of CPU cooler testing. After some debate as to the type of CPU cooler to employ I decided that a better test of an enclosure would be to use both closed-loop liquid and air cooling for every review, and provide thermal and noise results for each. For CPU cooler reviews themselves I'll be adding a "real-world" load result to the charts to offer a more realistic scenario, running a standard desktop application (in this case a video encoder) in addition to the torture-test result using Prime95.

But what about this new build? It isn't completely done but here's a quick look at the components I ended up with so far along with the rationale for each selection.

CPU – Intel Core i5-6600K ($249,


The introduction of Intel’s 6th generation Skylake processors provided the excuse opportunity for an upgrade after using an AMD FX-6300 system for the last couple of enclosure reviews, and after toying with the idea of the new i7-6700K, and immediately realizing this was likely overkill and (more importantly) completely unavailable for purchase at the time, I went with the more "reasonable" option with the i5. There has long been a debate as to the need for hyper-threading for gaming (though this may be changing with the introduction of DX12) but in any case this is still a very powerful processor and when stressed should produce a challenging enough thermal load to adequately test both CPU coolers and enclosures going forward.

GPU – XFX Double Dissipation Radeon R9 290X ($347,


This was by far the most difficult selection. I don’t think of my own use when choosing a card for a test system like this, as it must meet a set of criteria to be a good fit for enclosure benchmarks. If I choose a card that runs very cool and with minimal noise, GPU benchmarks will be far less significant as the card won’t adequately challenge the design and thermal characteristics of the enclosure. There are certainly options that run at greater temperatures and higher noise (a reference R9 290X for example), but I didn’t want a blower-style cooler with the GPU. Why? More and more GPUs are released with some sort of large multi-fan design rather than a blower, and for enclosure testing I want to know how the case handles the extra warm air.

Noise was an important consideration, as levels from an enclosure of course vary based on the installed components. With noise measurements a GPU cooler that has very low output at idle (or zero, as some recent cooler designs permit) will allow system idle levels to fall more on case fans and airflow than a GPU that might drown them out. (This would also allow a better benchmark of CPU cooler noise - particularly with self-contained liquid coolers and audible pump noise.) And while I wanted very quiet performance at idle, at load there must be sufficient noise to measure the performance of the enclosure in this regard, though of course nothing will truly tax a design quite like a loud blower. I hope I've found a good balance here.

Introduction and Technical Specifications


Water cooling has become very popular over the last few years with the rise in use of the all-in-one (AIO) coolers. Those type of coolers combine a single or dual-fan radiator with a combination CPU block / pump unit, pre-filled from the factory and maintenance free. They are a good cooling alternative to an air-based CPU cooler, but are limited in their expandability potential. That is where the DIY water cooling components come into place. DIY water cooling components allow you to build a customized cooling loop for cooling everything from the CPU to the chipset and GPUs (and more). However, DIY loops are much more maintenance intensive than the AIO coolers because of the need to flush and refill the loops periodically to maintain performance and component health.

With the increased popularity in liquid cooling type CPU coolers and the renewed interest and availability of enthusiast-friendly parts with the introduction of the Intel Z97, X99, and Z170 parts, it was past time to measure how well different CPU water blocks performed on an Intel X99 board paired up with an Intel LGA2011-v3 5960X processor. The five water blocks compared include the following:

  • Koolance CPU-360 water block
  • Koolance CPU-380I water block
  • Swiftech Apogee HD water block
  • Swiftech Apogee XL water block
  • XSPC Raystorm water block

Report: No Stock Cooler Bundled with Intel Skylake-K Unlocked CPUs

Subject: Processors | June 26, 2015 - 12:32 PM |
Tagged: skylake-s, Skylake-K, Intel Skylake, cpu cooler

A report from Chinese-language site XFastest contains a slide reportedly showing Intel's cooling strategy for upcoming retail HEDT (High-end Desktop) Skylake "K" processors.


Typically Intel CPUs (outside of the current high-end enthusiast segment on LGA2011) have been packaged with one of Intel's ubiquitous standard performance air coolers, and this move to eliminate them from future unlocked SKUs makes sense for unlocked "K" series processors. The slide indicates that a 135W solution will be recommended, even if the TDP of the processor is still in the 91-95W range. The additional headroom is certainly advisable, and arguably the stock cooler never should have been used with products like the 4770K and 4790K, which more than push the limits of the stock cooler (and often allow 90 °C at load without overclocking in my experience with these high-end chips).

Aftermarket cooling (with AIO liquid CPU coolers in particular) has been essential for maximizing the performance of an unlocked CPU all along, so this news shouldn't effect the appeal of these upcoming CPUs for those interested in the latest Intel offerings (though it won't help enhance your collection of unused stock heatsinks).

Noctua is a well known player in the enthusiast market for highly efficient, low-noise CPU cooling solutions. The latest additions to their lineup, the NH-D9L and NH-U9S, are smaller than the typical coolers we've reviewed here at PC Perspective in recent times. However, Noctua again proves their design prowess with the fact that these coolers held up to the rigorous demands of our testing at both stock and overclocking settings. And we all know that the Haswell and Haswell-E processors put major pressure on the cooling solution as the core speed and voltage is increased. Both coolers come standard with Noctua's SecuFirm2™ mounting mechanism, ensuring a secure mount between the cooler and CPU.

The NH-D9L CPU cooler is a dual tower cooler with a single included fan sandwiched between the two cooling towers. The unit can support up to three fans if desired. Noctua designed the cooler with their typical hybrid approach, combining a copper base plate and heat pipes with aluminum finned cooling towers. The base plate and heat pipes are nickel-plated for looks and to prevent corrosion. At an MSRP of $59.90, the Noctua NH-D9L offers puts a premium cooler within reach of the majority of computer enthusiasts.

The NH-U9S CPU cooler is single tower cooler with a single included fan, whose radiator is about double the thickness of a standard 25mm fan. The unit offers support for up to two fans if desired. Like the NH-D9L, the NH-U9S combines a copper base plate and heat pipes with aluminum finned cooling towers for an optimal hybrid cooling solution. The base plate and heat pipes are nickel-plated for looks and to prevent corrosion. The NH-U9S also retails at an MSRP of $59.90, giving potential users another affordable choice for cooling their processor.

Nice rack! It would look better if you added a Noctua NH-U9S or NH-D9L

You might want to hold off reading this review as these coolers are very likely to grace our pages in the near future but if you can't wait then HiTech Legion is the place to go to check out these small coolers from Noctua.  The 125mm NH-U9S fits in 4U cases while the 110mm NH-D9L can fit in 3U spaces, making them perfect for not only rack mounted cases but also for SFF builds.   The weights are also smaller than usual, with the 92mm fan installed they weigh 618g and 531g respectively.  For small builds with processors with a moderate TDP these are certainly worth your consideration.


"While Noctua’s new NH-U9S and NH-D9L were designed to comply with rack mount system standards, their low profile and horizontal airflow make them a natural choice for SFF and HTPC systems where CPU cooler space is limited. The Noctua NH-U9S meets 4U standards at 125mm tall, while the NH-D9L takes it a step further to meet the 110mm requirement of 3U standard."

Corsair Announces New H100i GTX and H80i GT All-in-One Liquid CPU Coolers

Subject: Cases and Cooling | February 10, 2015 - 12:05 PM |
Tagged: liquid cooler, H80i GT, H100i GTX, cpu cooler, corsair, All-in-One cooler, AIO

In the automotive world "GT" stands for Gran Turismo (or Grand Tourer), though it often connotes that a model will have more power and speed. Thus, in the parlance of PC components it makes sense that this would represent the fast version of a part - or in this case, a cooler version.


The Corsair H100i GTX

We haven’t reviewing one of the new "GT" all-in-one liquid cooler revisions from Corsair just yet (stay tuned, we will soon!) but we reported on the new H110i GT cooler during CES 2015, which is a large 280mm design. The two new coolers being announced will be the smaller 240mm and 120mm entries in the Hydro series of AIO coolers, and they presumably replace the venerable “i” versions of the well-known H100 and H80 liquid coolers in the lineup.


The Corsair H80i GT

Extending the same new colorful (and customizable) design options from the previously mentioned H110i cooler, the new H100i GTX and H80i GT share these features:

  • Improved coldplate and pump design
  • Dual SP120L PWM static pressure fans
  • Modular, tool-free mounting bracket for faster installation
  • Built-in Corsair Link support for configuring fan and pump speeds
  • Use Corsair Link to customize the RGB LED lighting and monitor multiple system temps
  • Support for Intel LGA 115x, 1366, 2011 and AMD AM2, AM3, FM1, FM2 coolers
  • 5-year limited warranty


The new H100i GTX water block design

There are a couple of important distinctions separating these new models (other than the obvious size difference). With the H80i GT this is the radiator thickness, which is a whopping 49mm thick, making its potential for heavy-duty cooling in smaller spaces a very interesting prospect. The H100i GTX on the other hand offers user-replaceable pump and radiator caps.


The H80i GT's 49mm thick radiator

The MSRP for the H100i GTX will be $119.99, with the H80i GT priced at $99.99. These will be available from the usual retail locations beginning this month.
