Manufacturer: Alphacool

Introduction and Specifications

Alphacool's Eisbaer is a line of pre-assembled liquid CPU coolers using standard parts that add quick-release connections to make adding components to the loop simple. Today we'll have a look at the 360 mm and 280 mm versions of the Eisbaer and see what kind of performance you can expect from an all-in-one solution from a respected brand in custom liquid cooling.

"With the Alphacool “Eisbaer”, we’re offering an extremely quiet high-performance cooler for every CPU on the market currently. A closed water cooling system that’s easy to install and can be easily and safely expanded with its quick-lock closure."

Not all AiO liquid coolers are created equal, of course, with different materials and approaches; and there are generally tradeoffs to be made between design and pricing. The best performance can result in pumps and fans that produce more noise than a high-performance air solution, while some liquid coolers manage to balance noise and performance in a way that makes liquid a far more attractive option - especially when overclocking a CPU.

True to the premium nature of a product line like this, Alphacool has incorportated first-rate components into the Eisbaer series including all-copper radiators, high-performance fans, and touches like anti-kink springs for the hoses. The capability of easily adding a GPU to the loop with the quick-lock closure (Alphacool offers a line of GPU products called "Eiswolf" that connect with these quick-lock closures) is a nice plus, and the use of standard G1/4 fittings ensures compatibility with custom parts for future expansion/modification.

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.

DSC_0100.jpg

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!

Be Quiet!, a popular German manufacturer of PC cases and power supplies is jumping into the liquid cooling game with the introduction of its new Silent Loop all-in-one (AIO) liquid coolers. Through a partnership with Alphacool, Be Quiet! Is launching three new coolers with 120mm, 240mm, and 280mm radiators. It is not clear exactly when they will be arriving stateside but pricing is approximately $124, $143, and $170 respectively.

The Silent Loop 280 AIO liquid CPU cooler.

The new coolers come clad in all black and feature a new pump design paired with copper cold plates and copper radiators. This is nice to see in the wake of aluminum radiators because using the same metals throughout the loop mitigates the risk of galvanic corrosion that will eventually occur in loops that use mixed metals.

The decoupled reverse flow pump courtesy OEM partner Alphacool.The AIO loop is paired with two Silent Wings 2 fans which use rifle bearings and can spin up to 2,000 RPM. To further set the Silent Loop series apart, Be Quiet! uses a nickel plated CPU cold plate, a radiator with a fill port to allow users to top up the fluids over time, and a reportedly innovative (read: not infringing on Asetek IP) "decoupled reverse flow pump" that spins at 2,200 RPM and allegedly reduces noise to nearly inaudible levels. The pump pulls water into the block and over the cold plate and then pulls it through the pump which is in a sectioned off area of the block.

As for the copper radiators, Be Quiet is using 30mm radiators on the Silent Looop 240 and Silent Loop 280 coolers with two fans side by side and a thicker 45mm radiator on the Silent Loop 120 with two fans in a push-pull configuration. Be Quiet! claims that the 120mm, 240mm, and 280mm coolers can handle wattages of 270W, 350W, and 400W respectively (these numbers are likely with the fans cranked to their maximum speeds heh). The included fans can be controlled via PWM and Be Quiet! includes a Y splitter that allows users to attach both fans to one PWM motherboard header – which is good since the CPU_Fan header is sometimes the only "true" PWM header offered.

The liquid coolers use Philips screws throughout for mounting the radiator, fans, and CPU mount and they are compatible with all the usual Intel and AMD sockets.

Several sites already have reviews of the new coolers including Kit Guru and Guru3D. According to Leo Waldock from Kit Guru, the Be Quiet! Silent Loop 240 is a "funky and nice piece of hardware" and while it did not blow him away it is competitively priced and performs very closely to the Corsair H100i V2. Out of the box the cooler was reportedly inaudible but with lackluster cooling performance; however, once the fans were cranked up from their normal 1,100 RPM to 1,400 RPM cooling performance greatly improved without sound getting too out of control.

In all it looks good aesthetically and appears to be easy to install. If you are in the market for an AIO and do not need fancy extras (LEDs, monitoring software, ect), the Silent Loop coolers might be worth looking into. Hopefully we can get one in for review so that Sebastian or Morry can take it apart... I mean test it! (heh).

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”.

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.

Cooler Master Introduces MasterLiquid Maker 92 AIO Liquid CPU Cooler

Subject: Cases and Cooling | August 17, 2016 - 11:43 AM |
Tagged: cooler master, MasterLiquid Maker 92, AIO, liquid cooler, self contained, convertible

Cooler Master has introduced an unusual all-in-one liquid CPU cooler with their new MasterLiquid Maker 92, a design which places all of the components together on top of the CPU block.

main.jpg

We've seen a similar idea from Corsair with the cooler first found in the Bulldog system, and later introduced separately as the H5 SF mini-ITX liquid cooler. Cooler Master's design uses a different arrangement, with push-pull 92mm fans sandwiching a radiator that rotates 90º to permit either a verticle or horizontal setup. The latter position allows for better low-profile chassis compatibility, and also adds airflow to motherboard components.

GamersNexus Disassembles an EVGA Hybrid Liquid Cooler

Subject: Cases and Cooling | August 1, 2016 - 09:38 PM |
Tagged: evga, asetek, liquid cooler, closed-loop

Well this is interesting. GamersNexus has about a twenty minute video (and a couple-page editorial) where they disassemble an Asetek / EVGA liquid cooler for GPUs. He spends the first half of the video with a discussion of previous videos, an overview of the industry and its split between vendors and manufacturers, and an explanation of various components including the difference between CPU and GPU plates. The second half of the video disassembles the cooler, talking about it as he goes.

The disassembly begins at ~9 minutes.

The availability of closed-loop coolers introduced me to water cooling. While I could be very careful to do everything right, I just don't trust myself to assemble a liquid-filled (non-conducting or otherwise) component that close to electronics. Part of that could be attributed to my childhood, where a dead PC meant no computer for x number of weeks, or months, because we could barely afford one at all. An assembled (and warrantied) cooler, though, while still intimidating when the tubes get even slightly torqued, is clearly designed to go in hassle-free and remain working without maintenance. That's a good part of why, while it's pretty obvious what is inside these units, seeing it first-hand is fascinating (at least for me).

be quiet! Introduces Silent Loop Liquid CPU Coolers

Subject: Cases and Cooling | June 1, 2016 - 10:34 PM |
Tagged: water cooler, Silent Series, liquid cooler, cpu cooler, computex 2016, computex, be quiet!, AIO

More be quiet! news from Computex as the company has introduced their first all-in-one liquid CPU coolers with the Silent Loop series; “silence-optimized” liquid coolers ranging from 120mm - 280mm.

Manufacturer: EKWB

Introduction and First Impressions

EKWB now has a pair of all-in-one liquid CPU coolers on the market, and today we have the 240 mm variant on the test bench. Long known as a supplier of water blocks (the WB in EKWB stands for water blocks, after all) and other parts for custom liquid cooling, how will EKWB's foray into self-contained liquid CPU coolers fare?

DSC_0117.jpg

The Predator 240 take a very different approach to self-contained CPU cooling, being a pre-assembled unit comprised of separate, and removable, parts. Though pre-filled and ready to use as a CPU cooler out of the box, the Predator 240 (and to a greater degree the larger Predator 360) can be expanded to cool additional components, and customized as the user desires.

This versitility doesn't come cheap, but the Predator is actually a pretty good value when you price out the components that make up the whole. Looking through EKWB's site the water block is available separately for $54.99, the radiator is $61.99, the two fans are $17.99 each, and then there's the pump, hoses, fittings, and coolant to buy.

DSC_0174.jpg

Still, at $199.95 the Predator 240 is at the top of the heap for price in this category (among 240 mm options), regardless of the apparent quality of the components. And while this may have more in common with a custom loop than your typical all-in-one CPU cooler, the only thing that really matters is performance. To test this I put it to work on the cooling test bench against some of the other coolers I have on hand. We'll see what it can do.

CRYORIG Announces A-Series Hybrid Liquid CPU Coolers

Subject: Cases and Cooling | November 4, 2015 - 03:24 PM |
Tagged: water cooler, liquid cooler, CRYORIG A80, CRYORIG A40 Ultimate, CRYORIG A40, CRYORIG, cpu cooler, closed-loop, AIO

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.

01_white-background_a40_1024.jpg

“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.

Corsair and MSI Introduce Hydro GFX Liquid Cooled GeForce GTX 980 Ti

Subject: Graphics Cards | September 16, 2015 - 09:00 PM |
Tagged: nvidia, msi, liquid cooler, GTX 980 Ti, geforce, corsair, AIO

A GPU with attached closed-loop liquid cooler is a little more mainstream these days with AMD's Fury X a high-profile example, and now a partnership between Corsair and MSI is bringing a very powerful NVIDIA option to the market.

HydroGFX_01.png

The new product is called the Hydro GFX, with NVIDIA's GeForce GTX 980 Ti supplying the GPU horsepower. Of course the advantage of a closed-loop cooler would be higher (sustained) clocks and lower temps/noise, which in turns means much better performance. Corsair explains:

"Hydro GFX consists of a MSI GeForce GTX 980 Ti card with an integrated aluminum bracket cooled by a Corsair Hydro Series H55 liquid cooler.

Liquid cooling keeps the card’s hottest, most critical components - the GPU, memory, and power circuitry - 30% cooler than standard cards while running at higher clock speeds with no throttling, boosting the GPU clock 20% and graphics performance up to 15%.

The Hydro Series H55 micro-fin copper cooling block and 120mm radiator expels the heat from the PC reducing overall system temperature and noise. The result is faster, smoother frame rates at resolutions of 4K and beyond at whisper quiet levels."

The factory overclock this 980 Ti is pretty substantial out of the box with a 1190 MHz Base (stock 1000 MHz) and 1291 MHz Boost clock (stock 1075 MHz). Memory is not overclocked (running at the default 7096 MHz), so there should still be some headroom for overclocking thanks to the air cooling for the RAM/VRM.

MSI-HYDRO-GFX-FRONT.png

A look at the box - and the Corsair branding

Specs from Corsair:

  • NVIDIA GeForce GTX 980 Ti GPU with Maxwell 2.0 microarchitecture
  • 1190/1291 MHz base/boost clock
  • Clocked 20% faster than standard GeForce GTX 980 Ti cards for up to a 15% performance boost.
  • Integrated liquid cooling technology keeps GPU, video RAM, and voltage regulator 30% cooler than standard cards
  • Corsair Hydro Series H55 liquid cooler with micro-fin copper block, 120mm radiator/fan
  • Memory: 6GB GDDR5, 7096 MHz, 384-bit interface
  • Outputs: 3x DisplayPort 1.2, HDMI 2.0, and Dual Link DVI
  • Power: 250 watts (600 watt PSU required)
  • Requirements: PCI Express 3.0 16x dual-width slot, 8+6-pin power connector, 600 watt PSU
  • Dimensions: 10.5 x 4.376 inches
  • Warranty: 3 years
  • MSRP: $739.99

As far as pricing/availability goes Corsair says the new card will debut in October in the U.S. with an MSRP of $739.99.
