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.

NZXT has created a stylish mid-tower enclosure with their Source 340 chassis, and made it an especially attractive option with a retail of just $69.99. Can this new case contend in a crowded market? We will find that out here!


With several interesting designs under their belt NZXT isn’t a surprising name when it comes to nice-looking enclosures. I looked at their H440 Razer Edition recently, and the H440 it was based on is a popular mid-tower enclosure with good looks and performance. This new S340 is very similar to the H440 but on a slightly reduced scale, and offers a more open internal layout with a reduction in hard drive storage space. This is a move that won’t work for everyone, but as I mentioned in the recent SilverStone Raven RV05 review being limited to a pair of hard drives and SSDs a fair tradeoff for a gaming or productivity setup.

On the subject of storage, like the aforementioned H440 and RV05 this Source 340 enclosure is another example of a optical bay-free design. There are no hidden slim-ODD bays here, and for any optical data needs a user will be required to use an external solution. I personally like an open layout and don’t use 5.25” bays at all anymore, and the added room in the S340 provides nearly unlimited space for long GPUs and stays clean with a clever approach to cable routing.

If you are looking for the biggest, baddest, power supply on the planet, then we have an exclusive review for you today.  But you better have a truck, a couple of strong friends, and very deep pockets!  


Miller Electric has been manufacturing large, industrial-grade power supplies since 1929.  They are one of the few power supply manufactures who actually design and build their own products, right here in the USA.  Miller’s The Power of Blue series of high-capacity power supplies includes models that go all the way up to an astounding 10,500 watts!

While we were not able to obtain a review sample of Miller’s flagship 10.5kW unit, we do have an exclusive review of the Miller XMT 300 PC, which can deliver up to 4,500 watts of pure DC power.   Talk about having some extra reserve capacity… wow!


The Miller XMT 300 PC is an external power supply that is about twice the size of a typical mid-tower case and is designed to normally sit on the floor.  It features a unique single, high-capacity +12V rail capable of delivering up to 375A (4,500W).  A power distribution module mounts inside the PC where the normal ATX power supply would go and breaks down the incoming +12V to the minor rails +3.3V, +5V, etc., along with providing a standard set of cables and connectors.  This allows one XMT 300 PC to power multiple PCs at the same time; up to twenty computers.

Miller XMT 300 PC Key Features:

•    Monstrous, single rail +12V output (up to 375A peak)
•    External main power unit sits on the floor
•    Can support multiple PCs at the same time
•    #6AWG copper cables for minimal voltage drop
•    Automatic fan speed control for optimal cooling and minimal noise
•    High efficiency operation (up to 87%)
•    Active Power Factor Correction  
•    1-Phase or 3-Phase line voltage
•    3-Year warranty

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

Subject: Cases and Cooling | March 30, 2015 - 07:32 PM |

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."

Watercooling your EVGA X99 with Bitspower

Subject: Cases and Cooling | March 24, 2015 - 02:12 PM |

Now that most of the features once present on motherboards have been moved to the CPU there is far less need to watercool your chipset.  However for the extreme overclocker there are advantages to cooling the MOSFETs on the VRM and PCH as well as the CPU itself.  Modders-Inc has just reviewed the Bitspower THOR EIX99, specifically designed for EVGA's X99 Classified and FTW motherboards. The acrylic housing for the waterblocks bring a unique look to your motherboard as well as offering improvements to heat management.  By installing the cooler Modders-Inc hit 4.5 GHz on an i7 5960X, not too bad for a $160 investment.  The installation was simple but if you invest the time to design a custom watercooling loop you can get even more performance out of this kit.


"Bitspower makes various options for water blocks that cover Gigabyte, ASRock, MSI, Asus and EVGA motherboards. Recently, we reviewed the EVGA X99 Classified and that motherboard is designed to push the CPU as high as possible if the cooling equipment allows. Bitspower’s THOR EIX99 is specifically designed to cover the EVGA X99 Classified as well as the EVGA X99 FTW motherboard, cooling the critical motherboard components and providing the thermal headroom that the MOSFETs and other parts require for a stable overclock."

Seasonic Snow Silent; if you prefer your PSU meek and pale

Subject: Cases and Cooling | March 23, 2015 - 02:30 PM |

The ability to deliver stable power is the primary attribute we look for in a PSU but the aesthetics should not be ignored, especially for modders and those with glass cases.  The Seasonic Snow Silent Series 1050W PSU is aptly named for its white finish which gives it a unique look in a very crowed market but the exterior does not tell the whole story.  With a total of eight 6+2 PCIe plugs and a 12V rail capable of providing 1044W @ 87 amps this PSU will certainly handle Crossfire or SLI and it will do so fairly quietly.  TechPowerUp liked the 7 year warranty as well as the performance and look of this PSU, especially considering it is priced roughly the same as the bog standard grey model which does not have the improved fan of this model.


"Seasonic released a special version of their Platinum offering with 1050 W capacity; it comes with a while paint job and is equipped with an FDB fan and a relaxed fan profile for less noise output, which will thrill users looking for a quiet high-performance PSU."

Cougar Launches QBX Mini ITX Case

Subject: Cases and Cooling | March 20, 2015 - 06:47 PM |

Cougar recently launched the QBX mini ITX case. The small form factor chassis is aimed squarely at gamers and enthusiasts looking for a high performance PC in a tiny box. 

The QBX is a completely black angular case measuring 7” x 10.2” x 14.5” packed with filtered vents. Front I/O is fairly standard including two USB 3.0 and two audio jacks. The case supports both air and water cooling while holding a ton of hardware. Specifically, the QBX is built to host Mini ITX motherboards, standard size (140mm) ATX power supplies, dedicated graphics cards (350mm), and CPU coolers up to 105mm tall. As far as storage, the QBX can hold a single 3.5” hard drive and four 2.5” solid state drives as well as a single vertically mounted slim optical drive.

[inline:files/news/2015-03-20/Cougar QBX Mini ITX Computer Case.jpg]

The case comes pre-installed with a single 90mm rear fan, and users can install up to six additional fans on the front, top, and side panels. The front and bottom vents have removable dust filters. A 120mm or 240mm radiator can be installed on the left side panel, but at most you can install one 120mm fan to cool the radiator.

[inline:files/news/2015-03-20/Cougar QBX Mini ITX Case Interior.jpg]

Cougar has engineered the case such that the power supply draws in cool air from the right side panel and exhausts it out of the top of the case to prevent adding extra heat to the system (it will be difficult enough to cool high end components in such a small case). Further, removing the left side panel reveals a hinged bracket that holds a fan (or the water cooling radiator) as well as the 3.5” drive bay and two 2.5” bays. Note that with a 240mm radiator installed, you will only be able to access a single 2.5” bay. This is a neat design but installing the CPU block of a closed loop water cooler is going to be a challenge depending on the length of the tubing.

[inline:files/news/2015-03-20/Cougar QBX Mini ITX Motherboard Tray.png]

There is some space behind the motherboard try to hide cables but you will likely need to do some custom cabling to not have it ultimately look like a rats nest considering how small this case is and how little area you have to work with, especially if you do end up installing all seven fans and five disk drives!

The Cougar QBX has an MSRP of $60 and will be available soon. More information can be found on this product page. Hopefully we can get one in for review to see how it stacks up to the Ncase M1 and Lian Li PC-Q33 Mini ITX cases.


The Fortress FT05 is the fifth iteration of SilverStone's Fortress series of enclosures, and, like the latest Raven case, this leverages the complete removal of 5.25" bays to reduce its overall size. We've seen this before as the FT03 completely removed optical support, but this enclosure is related far more closely to the current Raven enclosure than any of its predecessors.


Introduction: The Heart of a Raven

If you're familiar with SilverStone's product lineup you'll know about the Fortress and Raven enclosures which both currently feature an unusual 90° motherboard orientation. This layout places I/O on the top of the case, and helps expel warm air straight up. The Fortress was originally a more conventional design with a standard motherboard layout, but SilverStone switched this to mirror the Raven series with the second version, the FT02. However, just as the Raven series diverged from the original design language and layout of the RV01 with later versions, the Fortress series has undergone some radical changes since its introduction. With this fifth version of the Fortress SilverStone has converged the two enclosure lines, and the FT05 is essentially a more businesslike version of the Raven RV05 - though the design's more conventional exterior also contains noise-dampening material which helps to further differentiate the two enclosures.

Much as the current Raven owes much of its design to an earlier version, in that case the RV01, this new Fortress is a return to the design of the FT02. That earlier Fortress was a large (and quite expensive) case that combined great expandability with excellent cooling, taking the RV01's 90° layout and opening up the interior for an expansive, easy-to-manage interior. A considerable amount of the second gen's interior was devoted to storage, and the front of the case was dominated by 5.25" drive bays.

360mm of radiator; the Thermaltake Water 3.0 Ultimate

March 16, 2015 - 03:39 PM |

Using the Asetek Gen 4 pump and a radiator measuring 393mm x 120mm x 27mm the Thermaltake Water 3.0 Ultimate is a large cooler designed for serious overclockers.  The fans are rated at 99CFM and are set up properly with PWM connections to balance noise and performance.  Overclockers Club increased their i7-4770K to 4.2GHz and this cooler kept the CPU at an impressive 67 °C, topping the charts of the coolers they have tested previously.  They managed to get the chip running at 4.5GHz on 1.241 volts which raised the temperature to 75 °C but that was the highest frequency that particular i7-4770K could reach.  Check out their full review here.


"Cooling capacity is dependent on air flow and the Ultimate has you covered. You have close to 300CFM of air at your command, so expect to notice the fans when you crank up the heat and with a cooler this size, a little fan noise just goes with the territory. Thermaltake has refined a few components to make the installation about as easy as it can be. The low profile Asetek pump looks good and is quiet. Even at a 4.5GHz overclock, the Ultimate still has some thermal room if your chip can handle a higher overclock."
