CONCLUSION

The Alphacool NexXxos UT60 is an exemplary performer having very low restriction and top thermal performance across a very large range of fan speeds, it just doesn’t get much better than that.  Add to the performance a plethora of features such as the 6 barb ports, drain/fill bottom port, and screw protectors and you have a heck of a radiator.  There are a few minor cosmetic details such as easy tarnishing of the copper plugs and the copper foil logo, but nothing significant outside of minor cosmetics.  If cost and space is not a major consideration and you simply want minimal restriction,  top thermal performance across nearly all RPMs, top quality, and top features…the UT60 is a perfect “all copper” fit!

Cheers!

    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

      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?

    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.
