This is #8 in my series of triple radiators the Alphacool NexXxos UT60.  Unlike most manufacturers that may make 1-3 models, Alphacool makes many different models that vary in materials as well as thicknesses including 30mm, 45mm, 60mm, and 80mm. The Pro III and Xtreme III models are I believe the more value oriented copper tubes with brass end tanks and aluminum shrouds where the ST30, XT45, and UT60 are full copper higher end.  They also have some models that have a larger 420/360 sized core. Here we are reviewing the feature rich premium 60mm thickness model with a compact 360 core, 6 barb ports, a screw protection shield, and bottom drain port or air bleed.


A special thanks to Aquatuning for providing the review sample:



Notice the extra ports and screw protection shield

Alphacool Specifications:

The new Alphacool NexXxos radiators, a name that stands for experience and quality has come to bring a fresh breeze to the radiator market.

Every user of a water cooling system needs a radiator and everyone has different requirements towards the heat exchanger. Of course the customer always demands the best in its class. The Alphacool NexXxos radiators have come to compete with and to beat the best in their class and to be the best radiator in all sizes. No more endless choices without a clear class leader, the Alphacool NexXxos is the one tool for all your needs!

Alphacool has been the company to introduce new developments and improvements in the radiator and water cooling sector generally many times over the last years.
Following this tradition, the new NexXxos radiators are the first to truly deserve the “Full copper” attribute. All main parts, not only the fins and channels, but the chambers are also made from copper. This brings an improvement in performance where other radiators are left without a chance. The material already gives an advantage over the competition and the inner structure is up to par with the competition. Separated chambers give the coolant a clear direction, allowing high flow rates which improve the performance of the whole cooling loop.
Flat chambers on the heat exchanger increase mounting flexibility thanks to the reduced overall length.

Versatile and easy mounting is one of the main points, on which the research and development department at Alphacool focused. The chamber offers three possibilities for fitting installation on both inlet and outlet (not on the NexXos ST30). Less angled fittings are needed, improving flow rates and offering more mounting possibilities. Hence the radiator can even be installed in tight enclosures, where otherwise internal installation is not a possibility. A 1/4″ screw plug allows easy de-aeration of the radiator (on all UT60 and NexXxos Monsta) and hassle-free vertical installation of the heat exchanger. The threaded opening can even be used for filling, e.g. in combination with a Fillport.

Versatility is the essence of the new NexXxos series! The radiators are designed to be used with 120mm as well as 140mm fans and are available in different thicknesses. The choice of 30mm, 45mm and 60mm offers the perfect radiator for every purpose. Even mounting and installation of fans and radiator grills is easy and versatile with these radiators: The M3 threads are standard in the radiator sector and available in all lengths at an affordable price.
Even the dreaded insertion of a screw too far into the radiator does not result in expensive damage. Unlike other radiators, the NexXxos series is equipped with an internal protective ledge which stops the screw before it damages the fins.

Fin spacing is always an important factor in radiator design. The new series from Alphacool has a fin design which allows it to perform extremely well even with slow-spinning and medium-speed fans. This is not only pleasant thanks to the fact that it avoids unnecessary noise; it also means that the choice of fans that can be used with these radiators is not restricted.

These radiators are the result of experience and powerful performance meeting future-oriented design and well-thought through solutions.

    Thanks for the review, and for your work in general ! (from France 😉 )
    I’ve just received a 480 UT60 and when I first flushed it, Some copper bits where expelled. But then I could hear that somes copper bits were trapped at the bottom of the radiator.
    I flushed it again (for half an hour or so, both sides) and shaked it, but there is still some copper bits in it…
    Do you have any tip to help me with this issue ?

    • Martinm210 says:

      I would probably hook a hose barb to the faucet and remove the air bleed cap and see if you can flush it out that port opening. If you can’t flush it out and it bothers you, ask the vendor for an RMA.

  2. Neo Zuko says:

    I want to know specifically how the build quality of the UT60 compares to the AR-1 or GTX Gen 2. This is what is holding up my rad decision. I want the build quality of the SR-1 (I briefly owned a set of SR-1s) with the better range of the UT60. It seems Black Ice rads are either geared for low speed (SR-1) or geared for high speed (GTX Gen 2) with no in between rad with a range. The performance of the UT60 seems perfect but then I read things like the SR-1 / GTX Gen 2 still has the best build of them all.

    • Neo Zuko says:

      Typo: AR-1 = SR-1

    • Martinm210 says:

      GTX and SR1 are the best build quality rads I have seen. I rate them high. The UT60 I had was what I would call medium high. The copper emblem wasn’t perfect and the copper plating not coated so fingerprints are a problem. The paint was pretty good, but not quite up to GTX gloss black automotive paint quality. GTX is a step above in build quality, but the UT60 is also quite a bit better than value rads.

    • Abi says:

      Hi, will this radiator support 1/2″ by 5/8″ tubing?
      How can I find this out?
      And would you recommend this or the SR-1 for noctua nf-f12 fans

    Hi Martin!

    I want to replace the massing black ice gtx 480 with this one! would you suggest such a change. I want to replace the gtx because of its size.

    • Martinm210 says:

      Sure. That will improve your flow rate as well, the GTX series is generally a high restriction rad where this is very low. This will do well at slow speed fans as well where the GTX is really optimized for higher speeds.

    Thanks for taking the time and spending the money to properly test these different radiators. I havent built my liquid setup yet but the UT60 was on the top of my list. The 420mm version but i assume that performs as well as the 360. And I plan to use either the UT60 280mm or the “monsta” for a bottom rad. Theres more room in the bottom of my case to accomodate the thickness of the “monsta” than there is in the top. I actually just bought the NZXT Switch 810 for the upcoming liquid setup. From what im reading and some quick measurements the UT60 is the thickest i can fit up top with fans either pushing or pulling not both. Actually if i can fit fans inside to push i can possibly fit some fans on the outside to pull. I just found this site today and will be bookmarking and reading more later to see how some of the other things ive put on my list stand up to the competition.

  6. Josh says:

    I’m stuck between a GTX Gen Two 480 Highest Performance Radiator and the UT60 480, between the two, which one is actually the best? I will be running the SP120 2350 Fans.

  7. Jude says:

    Great review on this product. This helped in my decision on which to get for my build. Would you be doing one for their Monsta line in the future?

  8. JackNaylorPE says:

    Have a question……

    Above it says the RS360 dissipates 235 watts at 10C @ 1800 rpm. Ok so I went and used ya old Radiator estimator from here:

    Plugged in RS360, 1800 rpm and 235 watts and came up with a delta T of 5.31 C.

    Shouldn’t it have been 10 ? Where’d I go wrong ?

    • Martinm210 says:

      Two different test methods. The old estimator was based on my old open air test bench where the radiator is free to dissipate heat on all sides, tubes were not insulated, flow rate was fixed to 1.5gpm, heater bath was also not insulated, and there was zero case air flow restriction. The old bench had a lot of external heat loss and flowed freely so it produced better heat dissipated numbers that you could see in an external radiator mount scenario.The newer bench was improved to better simulate dissipation inside a case with some airflow restriction and insulated everything for more precision. Also the flow was not fixed, rather I picked an average pump setting and push through a block and flow meter to allow radiator restriction to influence resulting flow rates. This tested at more realistic flow rates and more fairly allows flow to vary depending on radiator restriction. It also has air flow restriction and ended up producing significantly lower dissipated numbers but gave more precise and repeatable results. It’s good for case conditions.

      The two are apples and oranges though, latter is more realistic.

      • JackNaylorPE says:

        Thank you Martin … result of different test methods equates to a difference of almost 2:1 in radiator sizing. So when we figure this out ….. well let me use an example. How crazy is this 🙂 ?

        I used 145 watts for CPU + 2 x 275 for GPUs or 695 watts

        Using your UT60 and XT45 tests on 360, interpolated for the Phanteks PH-F140SP’s fan speed (1250 rpm). The Phanteks is rated for 82 cfm $ 1.33 SP ( think your fans were rated for 66 cfm at a lower SP) but I can not begin to guess how to account for this

        I extrapolated out to a XT45 420 and UT60 280 using a simple surface area ratio. This gave me 170 watts for the UT60 280 and 256 watts for the XT45. Then, looking at ya archived fan tests, I used the 21% temperature drop ya got going from one fan in push to two fans in push / pull. This is probably exaggerated, but i then wound up with 206 and 302 watts respectively.

        Total is 508 watts. Now using ya old calculator w/ twin UT360s (454 watts from ya test) I get delta T of 10.69 …. adjusting for the 508 …. say 9.55 so under the 10.0 target.

        But using the data from the new more accurate testing, I need another 187 watts of cooling. I could add a 3rd Rad or increase fan speed to 1800 rpm. Based upon all your extraordinary efforts to date, do you have an estimate regarding how much we might allow as wiggle room for all those contributing factors where we get extra heat dissipation (i.e. tubing, rad sides, reservoir, etc.) ?

        Also, you know of a source for overclocked GFX card TDP’s ?

        Now off to look at ya fan testing for noise output of 1800 rpm fans.

        Would live to see ya test the Phanteks BTW

        Phanteks PH-F140SP_BK 140mm Case Fan – $18.00

        Phanteks PH-F140SP_BK_BLED 140mm Blue LED Case Fan – $20.00

    JackNaylorPE…If a cpu uses 145 watts of power, that does not mean those entire 145 watts are radiated in the form of heat only. The energy is used elsewhere too and the heat is only a partial amount of the total wattage used. A 2000 watt electric motor would not generate 2000 watts of heat when running.

    • JackNaylorPE says:

      As to the methods, you’ll have to take that up with Martin…. but a 2000 watt motor is an extremely bad example…..a 2000 watt motor produces energy output …. horsepower…things move … foot pounds , torque…..Kinetic energy ….. Ya can “do the math” look at the motive output and the electric input and come up with motor efficiencies generally in the realm of 86 to 92%.

      On the other hand, a CPU produces only heat….what comes out ?…. if not heat, where is all the rest of the energy, it what form is it ? It’s not kinetic …. …. it takes in electric energy and puts out a certain amount less with a potion which is consumed in doing so which is converted into heat. If not heat, then what form is this energy in ? How can I measure it ?

      You’ll not that test sites doing cooler reviews use heat blocks as a substitute for CPUs…. ever look at the wattage of those blocks ? Of what relevance would any of those tests be at 150 watts if the CPU wasn’t putting out that much heat ?…… they’d be useless and the testing and site information would be totally irrelevant.

      “The 125W heat load represents the upper limits of thermal solutions designed for AMD’s socket FM2/FM1/AM3/AM2/754/939/940 form factors, so it functions as a good basis for stressing each subject heatsink.”

      “In its second configuration, FrostyTech’s Mk.II Platform delivers a 150W and 85W heat load to socket LGA1155/1156 and LGA775 compatible Intel Core i3/i5/i7, Pentium 4/D/Extreme Edition, Celeron, Core 2 Duo & Core 2 Quad class heatsinks by way of a 30mm x 30mm copper interface die. Set within the center of the copper die is a Kapton encapsulated type-K thermocouple for taking temperature measurements once equilibrium is reached.”
