    Thumbs up [User-Review] Alphacool NexXxoS HD6970/6950-- GTX580/570 im Cartago´s Review







    Alphacool NexXxoS HD6970/6950-- GTX580/570 im Cartago´s Review--Inexpensive but good?





    Hello and welcome to my new review.





    In today's review will have for you the brand new Alphacool GPU Full Cover,
    the NexXxoS ATXP ATI HD6970/6950 along with the matching backplate







    Alphacool, cool, after years of abstinence in the Full Cover GPU
    stalks tremble now with low prices the competition can.

    But unfortunately, the quality and cooling performance by this?

    I'm going to try to answer in this review.
    Good performance and cooler are available for this series of almost all of the leading manufacturers of water cooling,
    Unfortunately the prices are very high. Until now you had to spend 80 € for such a cool,
    because the price of the Alpha Cool is cool almost a bargain and is currently around 64 €.
    Some, such as CPU cooler is already much more expensive. The matching backplate
    is extremely cheap and far around 14 € the Back Platen other manufacturers require in terms of the award.


    Is the low price the only thing that has to ask the cooler?
    We'll see later in the review,
    But first I want to introduce the technical details of the cooler and the back plate:




    Technical details of the cooler:



    Material: copper, acetal
    Dimensions (L x W x H): 175 x 111 x 16mm
    Weight: 1000g
    thread: 4 x ¼ inch
    completely SLI / Crossfire ready



    included:

    1x Cooler
    Thermal pads
    Thermal Compound
    Mounting material
    2 x ¼ inch plugs
    multilingual (en. engl. FRA.) Installation instructions




    Even here, one is missing the really big weight of the cooler of around 1000g, and when used as cover by acetal.




    Technical details of the Backplate:



    Material: aluminum
    Color: black anodized
    Dimensions (L x W x H): 175 x 85 x 6mm
    Weight : about 168g
    completely SLI / Crossfire ready



    The installation instructions are>here< zu finden.

    Lieferumfang:


    1x Cooler
    Thermal pads
    Mounting material
    multilingual (en. engl. FRA.) Installation instructions



















    Appearance:



    How do we get to see in later pictures, the radiator cap is black;
    the screw is copper and the Alpha Cool logo.
    Visually, it is not as massive as it actually is.
    The processing is where my present copy, good.

    No sharp edges or dirty drilled holes, the only thing that bothers me here
    are the long-running strip on the lid acetal.

    The machining marks in cooling block itself bother me, however not if they do not affect the cooling performance,
    what they do in this case is not, unfortunately, it can be seen in spite of vacuum packaging fingerprints of the workers,
    what is expressed in the same darker staining.
    The spacers are fixed to the heat sink
    and must not, for example. in the coolers of the EK, fixed difficulty with WLP.

    The thermal pads for memory chips have been designed
    only the need for voltage converter still be cut
    of course, is all over a small syringe of thermal compound on, but it is not clear who the manufacturer.

    The backplate also has stuck spacer and is
    in my case, clean processed, you are also tailored for thermal pads.


    And now the pictures:
















    Testsystem and Test.



    Before I start my test, I will give you the first time the test system.



    System:


    -Grafik: PowerColor HD6950
    -CPU: Intel Core i7 860
    -Board: Asus Maximus III Formula
    -RAM: G.Skill Sniper (F3-12800CL9D-8GBSR2) DDR3-1600 CL 9-9-9-24 2T bei 1,25V
    -Netzteil: be-quiet! P9 850W
    -Case: CoolerMaster HAF-X
    -Betriebssystem: Windows 7 Ultimate 64bit SP1



    Water cooling consisting of:



    Alphacool HF 14 Yellowstone - Copper Edition
    Alphacool Alphacool NexXxoS ATXP ATI 6970/50 Serie + Backplate
    Phobya DC-12 400
    Alphacool Cape Corp AGB2 Black Rev. 2
    Phobya Nova1080 + 4x Phobya G-Silent 180
    Aquaero 5 XT als auslese gerät
    2 Phobya Temp. Sensoren IG/AG
    AC DFM HighFlow
    16/10 Masterkleer schlauch




    As a test program serves the ever known FurMark, version 1.9.0
    The resolution was set to 1680x1050 2xMSAA with the options:

    Dynamic Background
    Burn-in
    Xtreme> Burn-in



    Before the test I had the water preheat with Prime95, start at FurMark she lay at 25.6 °, and reached a maximum temperature of 28.9 °.
    The room had at the beginning of the test temperature of 22.6 °

    After the water temperature no longer rose, a screen of running FurMark and GPU-Z, Sensors rider would be made. In the GPU-Z I have the maximum temperature has reached the card in the test indicated.

    All information with + / - 1 ° as the tolerance value

    And these are the values ​​reached









    GPU-Z shows in the card 4 GPU temperatures and temperature for the voltage converter,
    and these are the values​​:



    GPU Temperatures



    GPU Temp. #1: 42°
    GPU Temp. #2: 42°
    GPU Temp. #3: 42,5°
    VReg Temperatur: 61,4°


    Beautiful, the cooler does exactly what he should do, he keeps the card cool. The area of the voltage converter that is really not on the condenser assembly is passed through directly, with ca.62 ° right cool.


    Flow:



    I have also measured the flow resistance and come to these Values​​:

    GPU cooling water circuit without 184.6 Lph
    Water circuit with NexXxoS 178.8 Lph

    Thus corresponds to the back of the radiator was circulated around 5.8 Lph.





    UPDATE GTX570 + Backplate:



    Now comes a test of a NexXxoS NVXP NV570



    At this point I save the description and start with the same technical details:

    Technical Details NV570:



    Material: copper, acetal
    Dimensions (L x W x H): 175 x 111 x 16mm
    Weight: 1000g
    thread: 4 x ¼ inch
    completely SLI / Crossfire ready

    Delivery:
    1x Cooler
    Thermal pads
    Thermal Compound
    Mounting material
    2 x ¼ inch plugs
    multilingual (en. engl. FRA.) Installation instructions




    and Backplate:




    Material: aluminum
    Color: black anodized
    Dimensions (L x W x H): 175 x 85 x 6mm
    Weight: ca 168g
    completely SLI / Crossfire ready

    Compatible with AMD 580 / 570

    Delivery:
    1x Cooler
    Thermal pads
    Mounting material
    multilingual (en. engl. FRA.) Installation instructions



    Unfortunately, even with these cooler lid acetal was not free from machine marks as you get to see in the following images:


















    Let's get straight to temperatures
    I've had a surprise in terms of the original cooler.

    The surprise was that the card in FurMark
    been crashed regularly with the original cooler,
    and that once they have exceeded the 80 ° and the ladies and gentlemen went so quickly to control the fan on the map
    not turning up fast enough.

    itself:







    not even 1 minute. and the temperatures are already at 76 °




    And I have reached these temperatures with the NexXxoS NV570/580:







    Unfortunately, the GPU-Z shows only one GPU temperature, but think I should submit:


    GPU Temperatur: 42°









    Well here it shows how well the cooler actually is
    pity that the quality there's not as true as it should.

    At the conclusion change even the new found nothing
    Thus the conclusion is still time-variant but both.







    Conclusion:



    This time I miss the conclusion so easily.
    On one hand I am thrilled with the cooling power
    other hand, should Alphacool reloading in quality.
    Many would now say, "for the price it is all right, "
    may be the one that we see I do not.
    In particular, operates Alphacool a great effort to cool the
    to protect from discoloration, but it does not benefit if the worker
    in packaging has no gloves.

    The cooling capacity is as I said very good,
    because the cooler can very easily play with the big players in this industry.

    If the small quality problems in the course of the production is shut off,
    would be cool, at least for me, the best choice, especially since the price is really human.


    Since even the bottom line is unusual in two parts,
    I will also make the overall standings of the cooler.

    For the super-cooling capacity of the cooler the coveted „Cartago´s Review“ Award im Gold








    For the processing and quality impressions I forgive him, however, only the „Cartago’s Review“ Award in Silver









    Danksagung:
    I would like to especially Alphacool thanks for providing the test sample, the support and trust have placed in me, and the companyAquatuning,Asus, Intel, G.Skill, PowerColor, be-quiet!, und Masterkleer for their kind support.

    Can't seem to find DD 6970/6950 V1 blocks. I spent all my dough on my Sapphires so I need something inexpensive and works good. These seem to fit the bill and are not "plane-jane" looking like the xspc razors.

    ???

    Aren't Dangerden Blocks the el cheapo trashy kind that most people stay away from? (not many peeps using it even on XS)

    I mean, I got my Danger Den Radeon 5870 block when the 5870 was launched for 80 USD when other blocks were costing 110 USD (EK, Koolance) and up. It had a much simpler design with the flow bypassing the VRMs while more expensive competitors cooled the whole card

    Too bad that they don't have Nickel versions for the bling bling But good performance overall on the blocks.

    No, you can't. I have two units and the alphacool backplate is not required but it seems to help avoid flexing the card.
