DeepCool Infinity Series LT720 360mm – The Best Performance AIO

Box, Contents & Bundle

The plain carton box has a white sleeve depicting all information. This is an excellent way to lower the packaging cost.


All necessary parts to install the block on all popular CPU sockets are provided, including sets of screws to mount the fans on the radiator and the last to the chassis. There are also low-speed fan adapters, which I don’t find necessary since the fans are PWM controlled. Moreover, a 3-way fan splitter extension cable is provided to connect all fans to the same header.

The AIO’s fans are powerful, with up to 2250 RPM speeds. The static airflow is also high, on paper, at least. I must test them on the Longwin to have the exact performance readings. The fluid dynamic bearing increases reliability while lower noise output. According to DeepCool, the FK120 fan doesn’t exceed 33 dBA noise but expect them to be noisier with the radiator in front of them.

The RGB lighting on the block looks nice, creating a 3D effect. You can control it through a compatible mainboard’s software. The top cover of the pump, hosting the RGB LEDs, is attached magnetically to the main block.

The block comes with pre-applied thermal paste, which I removed since I use my own for all cooling measurements.

The pump is driven by a three-phase motor with a maximum speed of 3100 RPM. The base is made of copper for better heat transfer.

The aluminum radiator has 21 fins per inch, so it is pretty dense, requiring fans with high static pressure. The 410mm long tubes ensure you won’t have compatibility issues even in large chassis, and the clips between the tubes help in their management. It uses DeepCool’s anti-leak system to regulate the pressure.

  1. – Hope you’ll test “EK-Nucleus Lux CR360 D-RGB AIO” too (there’s also non-RGB (Dark version) and White version will be there soon as well…)
    – It’s the best AIO in 2023 (according to many reviewers, such as Kitguru, OC3D, Robeytech and others…)
    – Tech-Notice even showed it beats 420mm Arctic Liquid Freezer a bit when paired with 13900K… and some people commented that it’s just a couple degrees difference then with their Custom-loop cooling…
    – And the AIO is finally in stock again (it wasn’t in stock for a long time, I guess people are buying like crazy haha – I also bought it, hope it will arrive soon :))

  2. I just saw a review of “Phanteks Glacier One T30 Gen 2 D-RGB AIO (360mm)” and it’s 1 degree better then Nucleus Lux (on full load) – so you can test this one too 🙂

      1. oh, that’s very unfortunate but what about EK-Nucleus? Could you review that one instead (while they are still in stock)? haha 😀

  3. There’s also new “Asus ROG Ryujin III 360” cooler that’s even better then these 2 coolers… but the pump noise is frustrating according to “OC3D”, and the price is also insane 😅

  4. This AIO is the most suitable – especially in new generations of INTEL and AMD which are literally heaters.
    Very good and tested by me on 13600K and 5900X.
    I don’t like the desing of the PUMP that much, but that’s subjective.
    As far as the noise is concerned, it is not one of the most silent when I tested it with the Arctic Freezer II 360 with 6 120mm fans, but also with the 2 processors the difference was an average of -4C compared to the Arctic Freezer II 360 with MX6 thermal paste.
    The fans are very strong and DeepCool shows again in recent years that it wants to go 2 steps higher.
    The DeepCool cases need radical renewal and redesign.

    I should mention as far as the Fan Controller you mentioned (Corsair) is concerned, you can buy 10 seats from Arctic for €7 if you want to add another 3 for a push/pull arrangement and connect other fans.
    Also, DeepCool, for someone who wants to change thermal pads on the GPU, etc., provides very high-quality mm pads in many dimensions.

    Aris, goodevening! – We love you so much and we support you!
    Bless UP! my friend

  5. Awesome review. If you could test Arctic Liquid Freezer II 360 for reference. Another interesting cooler is Phanteks Glacier one 360 t30 gen 2. It uses the new asetek gen 8 pump , has a 30mm thick radiator with 20ppi and it includes the best fans you have ever tested (t30).

  6. Excellent review. I’m thinking about buying this water cooler but in white. The problem I will have will be adjusting the fans in reverse to comply with the case manufacturer’s recommendation: a Lian Li o11 Vision. About this, what I’m thinking (and please don’t judge me) is to put some nice (and not very efficient) reverse fans, with lots of LED effects on the front (intake fans) and on the back I’ll keep the ones that come with the AIO (pushing from behind), making a push-pull configuration. It makes sense? Thanks again for the review. Obrigado

    1. To be frank, I didn’t quite understand what you want to do with the reverse fans, but in any case if you want to get something good, look at the Lian Li UNI fans which have reverse models and RGB.
