By being one of the most famous companies providing accessories for watercooling systems it was about time that Alphacool introduced its own AIO cooling series which has some really nice features and that includes the option the AIOs in the series to be upgraded, rebuilt or refilled. The series was introduced with 4 different models made to deliver good and reliable performance while working at average noise level and most of all to satisfy the cooling needs of every user. The series includes:
- Eisbaer 120 which features a 120mm pure copper water cooling radiator with dimensions of 157 x 124 x 45mm, cooled by two Eiswind 12 fans in a push-pull setup and Eisbaer Solo waterblock.
- Eisbaer 240 which features a 240mm pure copper water cooling radiator with dimensions of 278 x 124 x 30mm, cooled by two Eiswind 12 fans installed side by side and Eisbaer Solo waterblock.
- Eisbaer 360 equipped with a 360mm pure copper water cooling radiator with dimensions of 400 x 124 x 30mm, cooled by tree Eiswind 12 fans installed side by side and of course Eisbaer Solo waterblock.
- Eisbaer 280 equipped with a 280mm pure copper water cooling radiator with dimensions of 316 x 144 x 30mm, cooled by two Eiswind 14 fans installed side by side and of course Eisbaer Solo waterblock.
For this test and review I received Alphacool Eisbaer 240 AIO and after my first contact with the product I am pretty curious and very excited to check its structure and the quality and most of all its performance while cooling my AMD Vishera FX-8350 processor running with full load for 14:30 minutes at default, a bit overclocked and even more overclocked frequencies.
So, let’s proceed with the article and check what is inside the package and after that check the main features of the product, and last but not least perform some tests.
Alphacool Eisbaer 240 was provided to me for doing a detailed test and review inside a massive and very stylish looking painted in black carton box, which features the company logo, the product name and the compatibility details accompanied by a picture of the Eisbaer Solo on the front panel.
On the back panel of the package I found only a faded picture of the Eiswind fan and that is it. Nothing else in matter of information is added on the box but all of the needed details are located in a very detailed leaflet, which is also the installation manual placed inside the box on top of a Styrofoam sheet, which is added to protect the AIO’s components.
|Installation manual||The AIO packed inside|
After I removed the Styrofoam sheet there was the AIO cooler, accompanied by the two 120 mm fans and all of the additional accessories, which will be needed so the cooler can be used with all modern Intel or AMD sockets. Of course, everything packed in separate nylon bags.
In addition, all of the additional accessories were packed in separate nylon bags according to their socket compatibility and purpose just to ensure that everything will arrive with the AIO in perfect condition and of course in full quantity. So, before we continue with checking the AIO’s structure, let’s check what we can expect from the additional accessories.
Alphacool Eisbaer 240 CPU ADDITIONAL ACCESSORIES
After I’ve spent some time taking all of the accessories out of their nylon bags arranging them for taking some pictures, this is the view which I got.
The standard Eisbaer 240mm accessories pack features:
- Black back plate needed for all Intel sockets
- Black metal front plate featuring 2 parts needed for all Intel sockets
- Black metal front plate featuring 2 parts needed for all AMD sockets
- A set of 4 metal thumbscrews needed to fasten the water block to Intel 2011 sockets
- A set of 4 metal thumbscrews needed to fasten the water block to all other Intel sockets
- A set of 4 metal thumbscrews needed to fasten the water block to all AMD sockets
- A set of 8 long bolts needed so the fans can be attached to the radiator and of course so the radiator can be attached to the case
- A set of 8 short bolts needed so the radiator can be attached directly to the case
- A set of 4 washers to be a base for the springs
- A set of 4 nuts for fastening the thumbscrews to the front plates
- A set of 4 springs
- PWM Y-splitter cable for powering and regulating up to two fans
- 2 x Eiswind 120mm fans
- Thermal compound
- Installation manual
All of the components including screws, springs and nuts are entirely in black to best suit the colour scheme of the AIO itself and according to what I saw in matter of a standard accessories pack I can easily say that I am pretty impressed.
The additional accessories pack will definitely provide the best possible compatibility and allow the AIO to work with every Intel and AMD socket inside every modern case which can host a 240mm radiator.
For now, let’s put the additional accessories aside until they are needed and check the AIO structure itself.
Alphacool Eisbaer 240 CPU STRUCTURE
To describe the Alphacool Eisbaer 240 in the most accurate and detailed way I spent a few minutes examining its structure and I should say it offers a pretty interesting and very sophisticated water block structure, attached to a high quality 240mm radiator via pretty thick and flexible tubes cooled by 2 Eiswind 120mm fans. Of course, in this article I am going to check all of the components in details one by one.
To keep the tradition, let’s start by checking the water block.
|Water block – top view||Refill cap|
Eisbaer 240 is designed with very massive and sophisticated water block structure with physical dimensions of L66 x W66 x H67.5mm with coolant capacity of 60ml, which includes:
- a very solid and perfectly milled square copper contact plate with dimensions of 50 x 50 x 3mm attached with 4 screws for secured and reliable leak-proof connection. Also the smooth and shiny polished copper base of the cooler ensures optimal heat absorption and can relay the heat over the fine slit structure of the cooler to the water quickly and efficiently.
- above the contact plate is located the very reliable ceramic bearing pump based on the Alphacool DC-LT Ceramic Ultra Low Noise pump which is made to operate at 7- 13,5V DC voltage range and rotate at up to 2600 revolutions per minute, which is delivering 70L/h flow rate inside the loop.
- Right above the water pump is the power and control circuit, which is directly powered from a motherboard fan header and that means the whole regulation of the water pump can be done automatically according to the motherboard fan profiles.
- To improve the overall appearance of the water block all of the components part of the block assembly are covered by cubical plastic cap, entirely in black, which also features the company logo on top as a cut through which a blue LED light can be seen and the dedicated filling port. Also the plastic cap is designed to offer additional transparent window on one of the sides. Of course through it everybody can monitor the water flow inside the loop when the AIO is running. In addition the insulated pump case is designed to further prevent noise generation and ensures that vibrations are almost completely absorbed.
Of course, to provide any cooling performance the AIO cooler requires solid and reliable tubes, which in this case are 320mm long made of PVC with 11mm outer and 8mm inner diameter connecting the waterblock to the cooling radiator. So the tubes don’t bend and stop the flow of the coolant, both of the tubes have been fitted with anti-kink coils. And the most interesting thing regarding the tubes is the additional quicklock closure mechanism with dimensions of 83 x 28mm on one of the tubes with which the circuit can easily be expanded to include anything from a radiator to a graphics card cooler.
And by mentioning the cooling radiator, let’s check its dimensions and what should be expected from it.
|Radiator – front view||Radiator – side view|
Alphacool Eisbaer 240 is designed with Alphacool NexXxoS 240 radiator with dimensions of 278 x 124 x 30mm made of pure copper and features 16 fins per inch. The overall structure raises the cooling performance enormously compared to the usual aluminium radiators used in classic AIOs. Also the radiator is capable to withstand up to 1,5 bar pressure.
Of course, to improve the overall appearance of the product, the radiator is also entirely in black, with just the company logo on the two sides in blue.
|Radiator – back view||Radiator – fittings|
The radiator itself is compatible with up to four 120 x 25 mm fans installed on both sides of the copper fins in push-pull setup. Of course, if someone decided to continue with such a setup he will have to find additional 2 fans and 8 long bolts. Anyway, the standard setup features only two identical Eiswind 120mm fans featuring a square black frame and propeller with 7 pretty wide and very sharply angled blades entirely made to provide the best possible airflow and static pressure levels.
According to the official information provided by Alphacool the Eiswind 12 model is especially developed for radiators and generate a high static pressure in order to push cool air through the radiator fins. The fans are made to operate at 550 – 1700 +/- 10% revolutions per minute range providing airflow level of 108 cubic metres per hour, with static pressure level of 1,66 mmH2O at noise level of 29 dB(A).
To attach them to the front side of the radiator I had to use the 8 long bolts.
And this is what the fans look like installed on the front side of the radiator.
To power and regulate the fans they should be connected to the PWM Y-splitter and the splitter should be connected to one of the fan headers on the motherboard. Preferable the CPU fan header for the best possible automatic regulation.
After I assembled the water cooling I can say that the AIO is really an eye catcher with its stylish appearance and inspires reliable and very serious performance capabilities. Whether this is true, we will find out a bit later.
To use the AIO I will have to install it using the provided in the package mounting kit and by following the official technical details published on the company web page the product is made to be compatible with:
- Intel sockets: LGA 775/1156/1155/1150/1151/1366/2011/2011-3/604/771
- AMD sockets: AM2/AM2+/AM3/AM3+/FM1/FM2/FM2+/G34/C32
For doing the tests I will have to use the original AMD back plate provided with the motherboard, the brackets provided with the AIO, some bolts, washers, springs and nuts as you can see on the picture below.
These are all of the parts which should be assembled so I can install the water block to the processor on my motherboard.
|Mounting brackets||AMD water block brackets|
First thing to do was to prepare the two front metal plates which will hold the water block attached to the processor.
Then add the springs and the washers to the bolts and then add the bolts in the holes on each corner of the brackets. Of course, to keep them in place I had to fasten the bolts with the nuts from below the brackets.
|Mounting brackets assembled||Ready for installation|
And the next step was to slide the 2 brackets in channels on each side of the water block and push them very hard so they can click and secure in position.
|Side view||RAM clearance|
And this is what the AIO water block looks like installed on the motherboard and I can say the only a bit hard thing is to click the front brackets to the waterblock. Everything else was just really easy and after everything is installed the connection between the waterblock and the processor was very tight.
|Inside the case||Radiator on the front of the case|
And this is what the AIO looks like installed back into the case ready for the stress tests.
Here I would like to add that by default my case is not compatible with 240mm radiators since it is an older design but with some zip ties I was able to install the radiator on the front of the case, sucking the warm air from inside the case and blowing it out of the case through fan filters located on the front of the case.
Alphacool Eisbaer 240 CPU TESTS
With the AIO fully installed inside the case I believe it is time to check my testing rig and to continue the article with the tests…

Case: SilverStone Raven RV-03
Power supply: Antec HCP-750W
Cooler: Alphacool Eisbaer 240 CPU
Thermal paste: Noctua NT-H1 thermal compound
For this test and review I am going to use the two Alphacool Eiswind 12 fans working at full speed of 1700 revolutions per minute, providing maximum airflow level of 103 cubic metres per hour, static level pressure of 1.66 mm/H2O at noise level of 29 dBA installed on the front of the radiator and installed on the front of my SilverStone Raven RV03 case.
The tests will be conducted in a closed system with:
- 2 x SilverStone AP181 – 180mm fans on the bottom panel of the case putting fresh air in and spinning at about 1200 rpm
- 120mm fan behind the motherboard cooling the socket and spinning at about 1000 rpm.
- Room temperature of about 20 degrees.
Both SilverStone AP181 – 180mm fans were connected together to the chassis 1 connector and were rotating at maximum speed.
And here I want to describe my testing method.
I will install Alphacool Eisbaer 240 and do stress tests using Prime95 AVX software with constant load on the AIO for 14:30 minutes with custom settings of minimum FFT size (in K of 128), max FFT size (in K of 128) and Run FFTs in place at standard frequency of 4.020 GHz (at 1.356V), at low overclock frequency of 4.220 GHz (at 1.380V) and at medium overclock frequency of 4.420 GHz (at 1.416V) using the two fans provided with the AIO system rotating at maximum speed of 1700 revolutions per minute.
Now let’s check out the test results:
|Alphacool Eisbaer 240 @4020MHz 1.356V||Alphacool Eisbaer 240 @4220MHz 1.392V|
|Alphacool Eisbaer 240 @4420MHz 1.416V|
All of the test results have been summed up in the following charts:
And the fan speed during the tests:
I believe it is time to express my feelings regarding the product.
Alphacool Eisbaer 240 CPU CONCLUSIONS
1. Alphacool Eisbaer 240 CPU performance:
Alphacool Eisbaer 240 AIO is a product for which I’ve invested a lot of time. Examining its sophisticated structure, the extensive additional accessories pack, taking tons of pictures, reviewing every single component of the AIO and finally after I am done testing I can say that this product really made me smile. A smile in that evil geeky way.
Eisbaer 240 itself is one really interesting and very sophisticated product made to deliver more than excellent build quality, very stylish and attractive design, a lot of cooling capabilities and that also includes expanding the loop and most of all very serious cooling performance. And yes, I can confirm that according to the test result the AIO is working just amazingly by keeping my power hungry Vishera processor working at pretty low temperatures even at full load for extended periods of time.I can say that this AIO will be able to cool every processor working at default or highly overclocked frequencies without a problem.
The thing which also attracted my attention is the server sockets compatibility, which of course use the same brackets for the desktop sockets but add the feeling that the AIO is reliable enough to keep even server processors, which are running 24/7 cool and stable.
Also by checking the water pump capabilities combined with the quicklock closure mechanism, which I really find as a great feature, I believe that even if the standard loop is expanded with additional radiators or VGA water block the AIO will manage to keep the coolant inside the loop at decent temperatures at decent noise level.
And by mentioning the noise here I just want to point out that throughout the tests when both the fans and the pump were working at full speed the Eisbaer 240 was noisy but for that performance of the processor I wouldn’t expect anything else. After performing the tests and all of the cooling fans and the pump set to auto the product was pretty quiet on a daily usage and that includes some gaming.
2. Alphacool Eisbaer 240 CPU appearance:
In addition to the amazing cooling performance I can say that the AIO is made to provide stylish design, which when installed inside a black middle ATX or even better, full tower ATX case will stay neutral and at the same time will definitely attract the attention. Also the anti-kink coils around the tubes somehow deliver a nice finish and inspire the feeling of reliability and high build quality. I can say that this product can be a good addition to a gaming rig or modding project entirely in the black colour scheme.
According to my review, I think that Alphacool Eisbaer 240 CPU deserves the following award:
Official Alphacool Eisbaer 240 AIO (MSRP) price : 114.95 euro
Official warranty: 36 months
Special thanks to Alphacool for providing us with a test sample!
Very good looking and performing product.
