XSPC EX360 Radiator

This is an old test I had never finished publishing, the XPSC EX360 radiator. The EX360 is XSPC’s slim thickness extreme radiator designed for top performance with slow to medium speed fans. While the RX360 is a proven top performer, not everyone has the space or budget for the higher cost RX series. The RS360 is also a good all around radiator, however in an effort to improve performance, a different type of construction was implemented to produce the EX line.

A special thanks to XSPC for providing the review sample:

  1. Yet another great review, have 3 EX rads and one RS and I must say I love my EX rads. From my understanding the new AX line uses the same core as the EX, just has a removable exterior.
    Thanks, Martin 🙂

    Hmm, double the FPI and relatively not THAT different performance from RX? I start doubting importance of FPI somewhat. Though some airflow resistance may be lessened from lower thickness of rad, turning combination of fpi&thickness closer to some middle finned full thickness rad.
    Also i wonder if this split fin gtx-like design might help lower fpi rads as well. But then again i’ve seen it so far only in dense-fpi rads, so probably manufacturers might have already tried that in-house, with not enough improvement to warrant manufacturing difficulty/costs increase.

      Yeah, there is something about the split fin that transfers heat better despite probably having lower air flow with the higher air restriction. The slimmer thickness helps too but the RS is slim also and I would have never guessed the EX vs RS results would be what they are. There is more to it than FPI for sure.

    Thanks for the testing. Did you get a chance to test both inlets to compare performance?

    • Martinm210 says:

      Yes I did. It has been a while since I ran these, but I could not measure anything different on my bench. I did find a small difference between two samples and there is a newer revision I haven’t tested, but I wanted to share what I had since I had a lot of people requesting the information and I thought it was interesting with the different fin construction and unexpected low speed optimization.

    “FWI, I understand that since this test, they have been working on a newer revision EX with even better performance so this test is already a bit outdated but I wanted to share what I had done so far.”

    You mention about a newer revision of the EX radiator. By this are you referring to the new AX lines or will there be another revision of the EX radiator using the EX360 name?

    • Martinm210 says:

      I assume EX, they asked if I wanted to test a new and improved sample. Since upgrading to a new SSD and Win8, I lost all my rad testing templates. Rad testing is also a huge PITA with having to carefully control ambient temps flat. Pretty much means I need the house to myself for a whole weekend doing nothing else. I decided to pass and focus on pump stuff that I enjoy more.

        ok no problem sir, do what you enjoy the most & remember to take care of yourself with rests. Was just wondering if there is a newer revision perhaps I should wait for the newer revision before buying a new radiator then. If it were the AX lines then I could get that instead since if its a revision then surely it will be better. Plus the core can be removed from the housing so easier to clean the dust out.

        I am in no rush yet as I am getting my other parts first for my build but my current choice for radiator is ex240 or alphacool nexxxous xt45. Still deciding which to get but I am pretty sure which pump to get after reading your D5 pwm pump results.

        • Martinm210 says:

          I may get back into radiator testing after moving to my new house, but that’s all on the rad testing for now. Hoping my new house will have a better thermostat to more precisely control ambient temps. We’ll see, but focusing on pump stuff for the next little while. Any rad tweaks these days are pretty small gains, so I wouldn’t worry too much about it.

          All good rads, you can’t really go wrong performance wise..:)

    Martin your work is phenomenal, as always. Thank you for posting the y=mx+b formula on the chart. I dusted off my old TI-83+ graphing calculator to get the #’s to compare Watts @ X RPM to the other rads in the old shootout summary. Much appreciated!

  6. […] will need higher pressure fans the EX360 is a good performer and doesn't need high pressure fans (the EX360 would be my choice) and the EK you can throw that in the […]

  7. Martin – I know this is an older test result, but have been doing some research on the EX radiators. Specifically thinking of trying the EX240 Crossflow – I know it’s single pass, but wondering how it might perform in relation to something like an MCR220. I’ll probably just give it a go and compare, but would be willing to contribute an EX360 Crossflow should you get back to radiator testing.

    I’ll build my loop and i’ll use a 360 rad, then is most recommendable buy a XSPC RS that EX?

  9. Sato says:

    Just wondering. How much performance difference the ex240 and ex360 have. I am kind of wanting to replace my still boxed ex240 and get an ex360 since the price are almost the same right now to my amazement at the moment I found a new boxed ex240 for sale that has the same price as an ex360 that I also found.

    If the ex360 does better job I might consider selling my ex240 and get the ex360. What should I do?

    • Martinm210 says:

      Hard to say exactly unless you know how hot your coolant is getting vs ambient. Average is probably 10-15 degrees. If it was 10, your new difference would be 10*240/360 or 6.7 degrees so..about a 3 degree improvement. But I have also seen 240 rads get up to 20C using slower fan speeds on hexacore overclocked processors. For example my 3930k overclocked running 800rpm fans will actually start throttling for overheating using a 240 rad, but my old E6600 would be fine. heat load, fan speed, and rad size are all huge variables. You would likely see a few degrees improvement and possibly more. Hope that helps, Martin
