A few months ago Lee reviewed the $40 Cooler Master Elite 110 and with the recent resurgence of mini-ITX systems it is worth revisiting this case. Measuring 8.2" x 10.3" x 11.1" (208 x 260 x 280 mm) it is a rather small enclosure which will lead to a crowded interior but a stylish looking and easy to place system. As you are limited to a 3" tall heatsink The Tech Report opted to go with watercooling as you can just squeeze a 120mm radiator in; in this case the Seidon 120V. The A10-7850K based "Casewarmer" was installed and with some tweaking The Tech Report managed to keep temperature and sound levels within a decent range but you should consider your cooling components with the knowledge that this case can get warm and loud without the right fans and heatsink.
"Cooler Master's Elite 110 is a tiny case with a price to match. Is it a good value? We loaded it up with parts and ran it through our testing gauntlet to find out."

Introduction and Features
Today we are going from one extreme to another. Two months ago we took an in-depth look at Cooler Master’s Elite 110 enclosure, which is a compact small form-factor case designed to house a mini-ITX system. Now we are going to the opposite end of the spectrum and will be taking a detailed look at the largest case Cooler Master (or most anyone else for that matter) has released to date, the HAF Stacker 935 Modular-Tower Case. In addition, the good folks at Cooler Master sent along a HAF Stacker 915F to show off how easy it is to expand a HAF Stacker system by adding one or more HAF Stacker case modules.

Because this case is so large (we will actually be reviewing three different cases together: HAF 915F, 925 mid, and 915R) we are going to split the review into two parts. In Part 1 we are taking a detailed look at the three chassis (features, specifications, etc.) and the in Part 2 we will start installing parts and build a full-size ATX system along with a mini-ITX system and also look at various cooling solutions.
CM HAF Stacker 935 (HAF 925/HAF 915R) (3) HAF 915s Stacked
The Cooler Master HAF Stacker 935 case consists of two pieces: a HAF 925 Mid-Tower enclosure and a HAF 915R mini-ITX case stacked together. The HAF 935 comes with the 915 mini-ITX chassis mounted on top of the HAF 925 Mid-Tower case but you can swap them around if you like because all of the HAF Stacker Series cases are interchangeable. This offers great flexibility for building multi-PCs in one chassis and provides a large amount of room for mounting all sorts of components like high-end water cooling systems, huge HDD arrays, etc. The HAF Stacker series can provide an excellent base system for some extreme case modding if desired.

With a total rated power of 650W and two PCIe 6+2 power connectors the CM V650S seems to be aimed at entry level gaming systems but the $180 price tag suggests a high end PSU. It is partially modular and it bears an 80 Plus Gold rating but perhaps the price also comes from Cooler Master's use of a new OEM, Enhance? [H]ard|OCP did find it at a much more reasonable $80 on Tiger Direct but it is now out of stock and it does not seem to appear on NewEgg at all right now. Overall there is a lot of good things to be said about the internals of the PSU but on the outside there is much left to be desired. Check out the review but perhaps wait for the second version of the V650S before purchasing one.
"Cooler Master has been off the enthusiast radar in terms of computer power supplies for a while now. It simply walked a different line than much of the rest of the field. Today however we have one of Cooler Master's second foray back into the high end with a mid-level PSU rated for operation at 650 watts."

The three stars of the Cooler Master V Series, the 850W, 1000W and 1200W are up for review at Legion Hardware. All three have a 135 mm fan for cooling and feature a single +12VDC rail though the amperage differs, 70A, 83A and 100A for the three respectively. The two lower powered PSUs feature a 5 year warranty and are rated 80 Plus Gold while the 1200W carries a Platinum rating and a 7 year warranty. The modular cabling is worth mentioning, it is flat which will allow you to have very clean cabling in your machine and may tip the scales towards this series if you like to keep your case clean looking.
"Finally, we have been very pleased with the Cooler Master V series, and believe that they would make a fine addition to any high-end gaming system. Enthusiasts will be able to invest their hard earned cash in a V Series power supply knowing it is backed by a full 5-year Cooler Master warranty, while the V1200 Platinum offers an industry leading 7 year warranty."

Cooler Master has been showing off a number of new products at Computex this year, and among the new announcments are a hybrid-switch keyboard and ultra-efficient (and ultra powerful) power supply.
NovaTouch TKL Hybrid Switch Keyboard
First up is the NovaTouch TKL mechanical keyboard, which Cooler Master has outfitted with their exclusive Hybrid Capacitive switches. Cooler Master claims these are "exceptionally quiet and suitable for heavy-duty typing or gaming," and the NovaTouch TKL offers support for Cherry MX switches (though it was not clear if they will be offering it with that option upon release). Another area of interest: the NovaTouch TKL has both a standard USB and microUSB connector!
Hmm... microUSB connector, eh?
Next we have a 1200W PSU with 80 PLUS Titanium certification (which you might remember calls for 90%+ efficiency at only 10% load!).
Titanium certification makes power supplies look super awesome
The power supply is Cooler Master's first "foray into digital" PSU design, and there is even a companion app with bluetooth control and monitoring functions. Finally! Now you can while away the afternoon checking and re-checking the efficiency of your PSU from your phone...
Not surprisingly, pricing and availablity are not yet available for these new products.
Computex 2014: Cooler Master Introduces Low-Noise Nepton 120XL, 140XL, 240M, 280L Liquid CPU Coolers

Cooler Master has announced their revised Nepton self-contained liquid CPU cooler lineup, and the existing models have been renewed with lower-noise designs.
The Nepton 240M
The revised versions seem to be using the the same radiators but employ new improvements in the pump/waterblock, as well as new low-noise fans. Cooler Master says the “Advanced Silent Driver” in the Nepton pumps will offer extremely low vibration levels, providing a120 L/hr flow rate at 11dBA. The units feature a Cooler Master-designed water block with a “large microchannel surface area and a high-efficiency jet impingement system to optimize hotspot cooling performance”.
New waterblock and fan designs
Cooler Master says their manufacturing process “eliminates microchannel imperfections in the waterblock to prevent blockage and allows for an increased surface area over 4 times greater than the competition, resulting in an extremely high performance waterblock.” The Nepton series also uses all-new “Silencio” fans, which Cooler Master claims will offer 11dBA noise levels and air pressure rated at 1.2 mmH2O. The cooling performance of previous Cooler Master self-contained liquid coolers has been dependent on some pretty loud fans, and while the stated 11dbA fan noise is likely based on the lowest PWM fan speed improvements in this area are welcome.
The Nepton 120XL
Cooler Master has not announced pricing or availability of the new Nepton 120XL, 140XL, 240M, or 280L models yet, but we should expect these products later this year.

Tagged: cooler master, V1200 platinum, PSU, modular psu
The Cooler Master V1200 Platinum power supply (PSU) is, as the name suggest, capable of delivering 1200 watts of power to your gaming PC, with a platinum 80 PLUS efficiency rating. At half load, which is probably its best-case scenario, this unit is 93% efficient. Cooler Master also says that it is backed by a 7-year "extended" warranty, although they do not clarify what is "extended" about it. If they just mean "really long" and it comes standard, without weird restrictions, then that is obviously a long guarantee.
The PSU is also fully modular and single rail. You can set it up such that the only cables coming off of it are ones that are in use, an obvious bonus for cable management. Also, being single-rail, the +12V can support loads of up to 100A. Users do not need to plan ahead and balance components across separate cables because they all draw from the same pool. Users with Haswell-based machines will also be able to use all C0-to-C7 power states, although it has been out long enough that it should not be an issue for anyone, anymore.
Pricing and availability is currently unknown and varies by region.
Typical Flow Diagram for Single Block Loop
All-in-one liquid coolers seem to be all the rage with several companies introducing expandable systems for integration of a system chipset or graphics cooling block to the loop. We will be exploring the performance of two of our previously reviewed coolers to see just how well those liquid coolers can handle the addition of an additional in-line graphics card block. Both the Koolance EXT-440CU Liquid Cooling System and the Cooler Master Glacer 240L Liquid CPU Cooler were used with the ASUS Poseidon GTX 780 graphics card placed in-line for testing.
Typical Flow Diagram for Multi-Block Loop
Several key factors come into play in a liquid cooling loop that the addition of a second block effects including:
- heat dissipation capacity of the radiator
- flow rate of the system
- resistance of the system components
Basically, additional liquid cooling blocks add more heat and longer tube runs to the system. This increases the amount of heat that the system must dissipate and introduces increased flow resistance to the system because of the increase of the loop size as well as the internal makeup of the added cooling blocks. The increase resistance and loop size directly effects the system flow rate and how hard the pump must work to keep the coolant flowing through the system.
For the purpose of this testing, we did not measure the liquid flow of the system directly. Rather, we measured the temperature of both components (the CPU and GPU) which directly correlates to the flow and heat dissipation capacity of the system. The ASUS Poseidon block adds little resistance to the system, besides the added length of the liquid channel, because of its simple U-loop channel internal to the block.
For additional information about the components used for this article, please see our review of the Koolance EXT-440CU Cooling System here, the Cooler Master Glacer 240L Liquid CPU Cooler here, and the ASUS Poseidon GTX 780 graphics card here.
Introduction: Budget Cooling Options and the Seidon 120V
The Seidon 120V is Cooler Master's newest 120mm all-in-one liquid CPU cooler, and its affordable price adds another option to anyone looking for an aftermarket cooler on a budget. But when we start comparing low-cost options it's valid to wonder just how much better a liquid cooler in this price range might perform over air. To find out we'll test the Seidon 120V against a popular budget air solution, and see how these aftermarket coolers compare against the stock solutions from AMD and Intel.

Cooling on a Budget
When you’re pricing out a new computer build these days it’s pretty easy to put together a solid group of components for $500 or so, and these will get you going on all the latest games at HD resolution. Sounds awesome! Of course, within that tight budget certain things are going to have to wait, and right up there on the list is probably some better cooling. It’s easy enough to change out a CPU cooler later, but if the stock cooler is doing the job within the thermal specs of the processor is it really needed? Clearly, AMD and Intel are not going to ship a cooler with their product that can’t keep it cool enough under stock workloads, but having better cooling can allow for overclocking as well as extend the life of not only the CPU, but the components around it on your motherboard. Aftermarket coolers are often able to cool more efficiently as well, producing less noise.
The selection of aftermarket coolers available is, well, ridiculous. As easy as it is to get lost looking at, say, every virtually identical stick of DDR3 memory, scrolling through product pages for CPU cooling is on another level entirely. Liquid cooling systems are much easier to navigate, as there are not only fewer of them, but the pricing segmentation allows for easier selection if you’re on a budget. For instance, the Seidon 120V at around $50 was the least expensive AIO option on Amazon when this review was started (actually coming in at 47.99 shipped, though this has been fluctuating quite a bit lately). Finding a suitable budget air cooler was not so easy, and it needed to be at least comparable to the performance of a liquid cooler, while coming in at or below the $50 mark of the 120V. (This might take a while…)
On the air-cooling side of things narrowing the selection to $50 or less doesn’t help much, as there are still (roughly) 50 million to choose from in that price range. There are going to be so many different preferences and opinions on these, so an easier alternative would be to simply follow the consensus pick, e-tail style. This intensive research project involved visiting Amazon and typing “cpu cooler” into the search box. (OK, that was pretty easy!) The plan was to put whatever came up first under $50 in the cart. Turns out the most popular air-cooler is also under $50 (not surprising). This top result was also from Cooler Master, their Hyper 212 EVO which was selling for under $34 shipped. Done.
