DeepCool is a renowned brand among the PC enthusiasts community when it comes to CPU coolers and we can see that with the LS720, which is an exceptional cooler for high-powered CPUs like the Intel Core i9 12900K. In this review, we will provide a brief overview of the DeepCool LT720 AIO liquid cooler and conduct a comparative analysis with some of the top-performing AIO liquid coolers in our collection. Our objective is to evaluate the performance capabilities of the DeepCool LT720 and determine what level of performance it delivers.

The LT720 comes packaged in the typical environmentally-friendly cardboard box, a long-standing practice. While the design is straightforward, all the essential product information is reliably printed on the box cover. The accessories that come with the LT720 includes the user guide documents, mounting brackets for both Intel and AMD platforms, screws for fans and radiator installation, and a splitter cable for the AIO unit.

While the included fans do look very similar to the fans from the LS720, it doesn’t have any RGB lighting design. I don’t really see this as an issue but if you’re really into the RGB fans, well, too bad for you I guess. My only complaint here will be the lack of the daisy-chain design like the ones we saw on the LS720, which is actually a very useful feature that I think should be included with these fans to make cable management easier.

The LT720 is the model with a 360mm radiator just like the LS720, but unlike what we can see on the LS series lineup, the LT series doesn’t have any 120mm radiator model like the LS320. The pump design is not as customizable but I actually do like this design more than the LS720.

Additionally, DeepCool has thoughtfully included a set of brackets to securely hold the tubes in place as well as some cables if needed, which directly contribute to a neater system appearance.

We can see the DeepCool anti-leak mechanism on the radiator, as advertised on the packaging. This mechanism serves as a pressure release system, allowing the AIO to automatically balance pressure within the loop, thus enhancing the safety of the unit’s operation.

The LT720 comes pre-applied with thermal paste, so you can use it right out of the box without having to worry about not having enough thermal paste. Also, the hard plastic cover is a guarantee that you will not run into issues like forgetting to remove the thin layer of plastic cover from the cold plate when installing the cooler.

While it may lack the extensive customization options found in the LS720, the LT720 possesses its own unique charm, primarily attributed to its pump block design featuring mesmerizing RGB lighting and an infinity mirror aesthetic. Notably, the LT720 offers excellent memory clearance, similar to the LS720. The seemingly intentional design of the pump cover ensures that users can install the pump with the tubes oriented toward the PCIe slots, optimizing both performance and memory clearance.

Test System Setup

During our evaluation, we conducted a comprehensive comparison between the DeepCool LT720 and our top-performing AIO liquid coolers within the same category. Our objective was to assess its capability to effectively manage the Intel Core i9-12900K. To conduct the test, we utilized a test system consisting of various components, which are detailed in the accompanying table below:

MotherboardASUS ROG Maximus Z690 APEX
MemoryV-Color Manta XPrism DDR5-6000
Graphics CardGeForce RTX 3080

ChassisStreacom Open Benchtable BC1 V2
Operating SystemWindows 11 64bit

Performance Test

The test was conducted at a room temperature of 28ºC, and the fan settings for all the AIO liquid coolers used in the experiment were left at their default configurations. This approach allowed us to gauge the performance of each cooler in effectively cooling the Intel Core i9-12900K.

To obtain accurate results, each cooler underwent a rigorous 30-minute stress test using Cinebench R23, with four cycles being run consecutively. The average temperature recorded during these tests is presented in the graph below.

Performance-wise, the LT720 is actually doing really well when going against some of the best-performing AIO coolers we have. Not only that it’s able to maintain the Intel Core i9-12900K at under 90°C, but it can also be seen performing on par with the LS720 and MasterLiquid PL360 Flux. Seeing this result, we expanded our list of best-performing AIO coolers with the LT720 as the latest addition to it.

The fan noise, on the other hand, is definitely not on the quiet side for sure. It hasn’t reached the level which I’ll call unbearable but that only happens when the CPU is actually on high load.

Final Thoughts

Let’s start with the downside first. My only complaints for the LT720 are probably the fan noise when the system is on load, and the lack of the daisy-chain design on the included fans that directly affects the cable management of the system. I know it’s not easy to make a good cooling fan that runs quietly while keeping the cost down, but I really hope DeepCool can actually consider implementing more of these daisy-chain capabilities on their cooling fans, especially those that are specially designed for radiator use.

From the test result we have, I can say that the LT720 and LS720 have a lot of things in common, that includes the performance – they’re both really exceptional AIO coolers for sure. It is easily one of the best AIO coolers you can get for an Intel Core i9-12900K or perhaps, even the Core i9-13900K as well. The only differences are probably the pump cover, cooling fans, and the extra RGB bling, which I think is more suitable for people who don’t like RGB lighting, just like me.

Now for the price, the LT720 is retailed at $139 and this makes it the alternative option to the LS720 if you don’t want that much RGB in their system, which I will gladly recommend at any time.

  • Solid performance out of the box, no additional adjustments are required
  • Excellent clearance for memory slots
  • Included fans come with vibration-dampening sides
  • Come with a pair of brackets to keep the tubes organized
  • The pump is quiet even when the system is under load
  • Thumbscrews make installation easier
  • The mirrored finish part on the pump is a real fingerprint magnet
  • The fans are not daisy-chainable like the ones on the LS720
