Introduction and Specifications

Fractal Design is well known in PC enthusiast circles for their excellent cases, and they also entered the self-contained liquid CPU cooler market in 2014 with the Kelvin, and today are releasing a brand new cooler lineup called Celsius. There are two models being introduced, with the 360 mm Celsius S36 and the 240 mm Celsius S24; the latter of which we have for review today.

While on the surface this might appear to be a standard 240 mm all-in-one liquid CPU cooler, there are some key features that help to differentiate the Celsius lineup in an increasingly saturated market. The hoses (themselves flexible rubber in nice-looking sleeves) are attached at both ends with metal fittings, with the radiator side the standard (and removable) G1/4 variety, and the fans connect via an unusual radiator-mounted header that receives power via a hidden fan cable in one of the sleeved hoses. Additionally, the Celsius coolers offer a dual-mode setting with the choice of automatic fan control or PWM passthrough from the motherboard - and this is controlled via a clever switch built into the trim ring around the pump.

I have been impressed with the low noise of Fractal Design fans in the past, and I went into this review expecting a very quiet cooling experience. How did the Celsius S24 fare on the test bench? Read on to find out!

EK's Supremacy line of CPU waterblocks are well known for their performance and style. Their latest version in this block line, the Supremacy MX, advances their design in the hopes of getting more optimized performance out of a less costly version of their award winning block series. The base Supremacy MX CPU waterblock is a copper and plexi construction using the same jet-impingement and micro-channel design as that used in their previous block versions. The block comes fully assembled from the factory with a single CPU mounting bracket type (in this case, the Intel version). Note that additional CPU mounting kits are available for purchase. With an MSRP of $54.99, the Supremacy MX waterblock offers a compelling purchase in light of its performance potential.

The block is assembled with hex-head screws going through the copper base plate with rubber grommets ensuring the integrity of the block internals. The top aluminum cover plate is held to the plexi top using short hex-head screws that thread directly into the plexi top plate. The center inlet feeds the micro-channels embedded in the copper base plate through the jet-impingement assembly. The mounting bracket sits in between the top plexi plate and the copper base plate, making any an interesting upgrade if you want to switch out the CPU mount plate to use the block on a different CPU family (like going from Intel to AMD Ryzen for example). The aluminum top plate gives the block a sleek appearance and acts to redirect illumination from the side mounted LEDs (if you choose to use LEDs with the block that is).

The block is held together with screws going through the nickel-plated base plate with a snap-on top cover. Use of a snap-on aluminum top cover gives the block a sleek appearance. Further, it allows for easy customization of the embedded LED color not to mention the top cover color by switching out the top cover plate without interfering with the block internals. Alphacool offers a variety of top cover plates and customization kits for the Eisblock XPX water block to match virtually any system theme setup. With an approximate MSRP of $73 US, the Eisblock XPX is at price parity with other high-end water block offerings.

Introduction and First Impressions

The GENOME is the world’s first computer case with an integrated liquid-cooling system, and this unique design allows users to simply drop in the main system components and have a complete system with liquid cooling loop (and with very little effort).

PCPER_GENOME_01.jpg

“One of the first things many of us look at when considering the purchase of a new case is whether it will accommodate the cooling subsystem that we’d like to install in our next build. Can you install big enough radiators? Is there room in the main interior space for the reservoir and pump that you have your eye on? How will it look when everything is put together? To improve PC user experience is why DEEPCOOL comes up with GENOME, which is a PC hardware component, consists of an ATX PC case and an extreme liquid cooling system.”

When I first heard about the GENOME I was nonplussed - wondering how I would even go about reviewing at since it defies conventional classification. It’s as much a CPU cooler as a case, and DEEPCOOL calls this simply a “cooling system”. But however you label it there is no doubt that this novel concept has the potential to produce a polished build with a minimal effort (if it is well-designed, of course).

If you have switched cases as often as I do (no one should - I do it once every week or two), you might appreciate any sort of labor-saving design in a case. As a reviewer moving a test system from one enclosure to the next, I just want an easy build with adequate clearance and good cable management (these requirements are true for most normal people as well). Some cases are much easier to build in that others, and I was very curious to see how something which sounds quite complex would actually come together.

Introduction and Specifications

In this roundup we'll explore the performance of three premium (and large) air coolers - with the ultra-popular Cooler Master Hyper 212 EVO in the mix to see how this $29 option stacks up against the big dogs on test.

DSC_0033.jpg

Many of the large air coolers on the market are built for ultra-efficient cooling at whisper-quiet volume levels. With massive heatsinks (and sometimes pairs of them) they can often cool demanding CPU loads with minimal fan speeds, and this usually results in very low noise output. Another advantage is the increased thermal headroom such a cooler provides, which can allow for overclocking without the need for liquid cooling - or even much additional noise.

So what coolers are included? In alphabetical order we have:

Can the $29 Hyper 212 EVO hold its own in this group?

Kicking Cooler Testing up a Notch

I reviewed the Thermalright Le Grand Macho RT recently, using a Core i5 6600K-based test platform (the Scythe Ninja 4 was also reviewed using this platform), and readers correctly pointed out that a cooler of this size should really be tested with some more challenging thermal loads. The Core i5-6600K is a quad-core, single-threaded design with a 91W TDP, and in moving to a new CPU cooler test system I decided to make the jump to the 140W TDPs of Intel's LGA2011 processors.

So I ended up with a Core i7-6800K; a newer Broadwell-E design with a 6 core/12 thread configuration (and of course that 140W TDP). The base speed of the CPU is 3.40 GHz, with a maximum turbo frequency of 3.60 GHz. Without much trouble I was able to push the CPU to 4.0 GHz on each core, and proceeded to test each of these coolers at both stock and OC frequencies. My hope is that the results to follow will adequately demonstrate just how effective these coolers are when really pressed.

Introduction, Specifications, and First Impressions

Cooler Master has introduced a pair of new all-in-one liquid CPU cooler designs, with the former Nepton series now replaced by the MasterLiquid Pro 120 and 240. It is the larger of these that we have for you today, and in this review we'll see just how well this new design performs.

DSC_0009.jpg

“Based on our expertise in thermal technology, we reengineered how liquid absorbs and expels heat throughout the all-in-one (AIO) closed loop of the cooler. Our holistic approach to the flow puts in your hands a comprehensive cooling machine that lasts longer, performs better and requires virtually no maintenance.”

The MasterLiquid Pro 240 uses what Cooler Master is calling “FlowOp Technology”; a series of design choices that are intended to improve all aspects of the cooler's efficiency. It begins with the pump, which “sprays liquid directly at the center of the water block”, and the block, which offers what Cooler Master claims to be 657% more surface area (thanks to many more “ultra-fine fins on the copper base”) and 40% greater performance compared to previous designs.

The radiator features a square fin design, which the company claims “creates greater surface area for absorption of the heat and allows for spacious airflow”.

radiator_fins.jpg

These claims, along with a pair of Cooler Master’s new “MasterFan Pro Air Balance” fans, make this new design sound very powerful, and I couldn’t wait to get it on the testbench to find out just how powerful - and quiet - it might be.

Introduction and First Impressions

The Le Grande Macho RT is a massive air CPU cooler design from Thermalright that pairs a very large heatsink (with 7 heat pipes) with a quiet 140 mm fan. It certainly looks impressive, but you'll want to read on to find out how it performed on our test bench!

DSC_0264.jpg

"With the Le Grand Macho RT we offer an actively cooled version of our famous semi-passive flagship. Thanks to the silent-running TY 147 B with fluid dynamic bearing, the Le Grand Macho RT can cool up to 280 watt.

The design of the heat sink has not been changed and is still asymmetrical. This offers the highest possible compatibility to the most recent motherboards. Thus it is guaranteed that the Le Grand Macho RT neither blocks the RAM spaces, nor the top-most PCIe slot on current ATX-boards."

DSC_0257.jpg

While the Le Grand Macho RT is one of the largest coolers I've tested, it is still a little smaller than Thermalright's famous SilverArrow dual-tower cooler. In fact, the 159 mm height means it will fit a large number of enclosures (with 165 mm being a common limit).

The single-fan design of the Macho makes it look like a good candidate for low-noise air cooling, and it's physically larger than the Scythe Ninja 4 cooler I reviewed back in January - which was, incidentally, the quietest cooler I've tested to date.

Why install this giant on a mini-ITX board? Why not!

High-End CPU Cooling Roundup: 5 Water Blocks Compared at ComputerBase

Subject: Cases and Cooling | August 3, 2016 - 12:56 PM |
Tagged: XSPC, water cooling, water block, roundup, raijintek, Phobya, liquid cooling, Heatkiller, cpu cooler, Alphacool

Computer Base (German language, Google-translated link here) has rounded up five CPU water blocks to see which might offer the highest performance on their Intel Core i7 3960X-equipped testbed.

logo-630x354.0af191a3.jpg

The tested water blocks include:

  • Alphacool NexXxos XP3 Light V.2
  • Phobya UC-2 LT
  • Raijintek CWB-C1
  • Heatkiller IV Pro Pure Copper
  • XSPC Raystorm Pro

The review offers an thorough look at the design of each water block, as well as an interesting look at the effects of flow-rate on performance:

"The test has been shown that with increasing flow rate decreases the temperature difference of the water before and after heat sinks. However, the question arises whether a higher flow also has a positive effect on the cooling performance itself. A negative effect of increasing flow as well: Most pumps are unthrottled very loud to work, so that a reduced pump capacity is useful for a silent water cooling."

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.

DSC_0411.jpg

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.
