Alphacool NexXxoS UT60 360 Radiator

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

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.

    As a follow up …..

    “Lets say that you have three servers, each consuming 300 watts of
    electricity, and a monitor producing 100 watts of heat. So the heat load
    from the electrical equipment is 1000 watts total. Now it is true that a
    few watts of power exits the room in the wires, but essentially all of the
    electric power that the equipment uses is converted to heat.”

    Finally, you’ll also note that plugging anything into the PSU calculator

    and for determining ya heat sink size

    give the exact same number

    • Martinm210 says:

      It is true that there are heat losses through the motherboard, but there are also significant cooling losses with heat recirculation, dust, and air flow restrictions. Even more important is the actual loading in real world use vs. synthetic testing. Any amount of heat/cooling planning is good enough, don’t get too caught up in the being exact.

      • JackNaylorPE says:

        Certainly true …. I make that point often over on OCN….. I always calculate the numbers and find out what the math says should be the number. That’s the idealized goal :)…… then we get to reality. As I remember the radiator sides / shroud is not accounted for in your graphs….there’s also the res, tubing, fittings all of the components, backplates, etc.

        So once I get the number for the 10C “ideal”, I look at what can realistically fit and look for the most cost effective / realistic alternative. In my current build, at 1250 rpm, I can exhaust 62% of the idealized heat output thru my rads…. this creeps up to 87% at 1800 rpm. At real loads….I think I’ll ever tax even the 62% loading.

    Hi Martin,

    I am going to build a liquid cooled rig, let’s say with several 7990.. It is better to rely on a single massive radiator like the mora 3 pro (9-18×140) or several smaller like this one, the ut60 360?
    I guess the first solution is the most efficient, but the second one has the advantage to insert a radiator between some gpus..

    What do you think?

  3. Guy Cotnoir says:

    Hi Martin.
    Considering the very linear curve of the UT60 performance, would it be fair to assume 600 w ofcooling at 4000 rpm (twice that at 2000 rpm and 4 times that at 1000 rpm) ?

    And what cooling power would you estimate at 4000 rpm in push/pull?

  5. JackNaylorPE says:

    I can’t imagine being in the same room w/ 4000 rpm fans, I can’t be in the same room with a H100 and it’s 2,600 rpm fans due to the 60 dBA vacuum cleaner level equivalent sound.

    As for cooling, martin would know better but from my experience with building ventilation, after a certain point, the air resistance and turbulence brings a point of diminishing returns.
