After our test of the LS720, the DeepCool brand did not stop and proposed a new series of watercooling kits. It is indeed the LT, a range of two kits offering a new visual aspect, more worked, especially at the pump level. Like a Kraken kit, the LT Series benefits from infinite depth lighting effects. And among the two AIOs that make up this range, we received the LT720, the bigger of the two! So let’s see, through this test, what it has in the belly!
Presentation :
As we said before, the LT series is rather limited since it offers only two models. Indeed, we find the LT720 in 360 mm, the one we will test. Secondly, there is the LT520, a more compact version, in 240 mm. Nevertheless, DeepCool indicates that these are high performance oriented products.
On its website, the company highlights the performance side via a fourth generation water pump. The performance is optimized via a thick copper base with micro-channels optimizing the flow of liquid that will be driven by a three-phase motor operating at up to 3100 rpm.
To ensure ventilation, this 360 mm version is equipped with three 120 mm fans, FK120, which we met during the test of the AK500. According to DeepCool, these are powerful and efficient mills.
With this, we can also count on a simple and intuitive assembly mechanism. In addition, the assembly is discreet thanks to the black mounting arms, so as not to attract too much attention. Also, the pressure on the processor is optimal, according to the company.
Finally, we can count on a devastating look thanks to a pump cover very worked. It then has several lighting zones with infinite depth effect that can be controlled via the motherboard. Can’t wait to see it in action!
Currently, if we want to get this AIO, we will have to turn to Amazon which references it at 165 € and should be available soon on the American Amazon. In fact, it is a little bit cheaper than the LS720, its predecessor.

Unpacking
In terms of packaging, we find some sober, like the LS720 finally. As we can see, the box is made of cardboard with some green writings/cyan markings. In addition, the set benefits from a white cardboard visor with a reminder of the features and functions.
Inside, we find our watercooling kit protected in a cardboard mold. Again, the fans, pump and radiator are packed in plastic bags. Only the accessory part benefits from yet another cardboard box.
The radiator :
Without further ado, we continue with a small tour of the radiator, which, we will not lie, is identical to that of the LS720. Thus, it offers dimensions of 120 (W) x 402 (D) x 27 (H) mm. Its structure also remains unchanged with a total of 12 channels for the circulation of liquid within it. The construction is still made of aluminum. In short, this is a rather classic model because of its thickness. We are far from the 38 mm of the AIO Arctic, Phanteks or even Alphacool with their latest Core Ocean T38.
On the other hand, we salute the construction, very well done. The radiator has a square shape and is painted with a black paint, uniformly applied. On one of the edges, we even find the brand’s logo, although a little discreet. Anyway, it looks good, and we are far from the Asetek kits with their not always very neat radiators.
Concerning the pipes, two 41 cm long tubes join the pump and the radiator. Again, just like the LS kits, this LT720 benefits from two plastic clips to manage the gap between each pipe to take care of the aesthetic aspect. Again, we don’t complain about the finish, as a nice thin nylon sheath covers them. The work is far from being as rough as on the recent Alphacool kits… But it’s not the same price range either.
The waterblock:
Who says new series, also says new design of waterblock. For the occasion, the brand now switches to a totally square and angular cover where the angles were rounded on the LS Series. However, we can distinguish a part with mirror finishes: this is where the aRGB lighting is located. As you can see, the cover is removable, held by magnets. When mounting, it will have to be removed to screw the pump onto the CPU.
In terms of size, it is also larger than the previous series. Thus, the pump block of the LT720 is 94 mm wide, 80 mm deep and 68 mm high. The connectivity remains simple since it is composed of two cables, the first one with three pins that will connect to an AIO_PUMP header of your motherboard. The second one will be aRGB, with three pins and will start from the cover, its objective, to allow the management of the light.
Once again, we find a non-nickel-plated copper base. On this last one appears pre-applied thermal paste. Unfortunately it will be for single use only, once mounted, it will be necessary to buy a syringe of paste if we wish to reassemble it after disassembly.
Again, the copper base is screwed to the rest of the pump. To hold it in place, DeepCool opts for a dozen Torx head screws. That’s all it takes to hold this 5.3 cm x 5.3 cm base in place. By the way, don’t worry, normally it should cover mainstream CPUs from Intel andAMD without any trouble. However, for Threadrippers, it’s a bit more complicated.
Compatibility
With the LT720, DeepCool ensures exemplary compatibility since the vast majority of recent platforms are compatible:
- Intel : LGA-1100 – LGA-1200 – LGA-1700 – LGA-2000
- AMD: sTRX4 – sTR4 – AM5 – AM4
As we can see, the kit will fit on all platforms currently on the market. It is even compatible with high-end sockets such as LGA-2000 andAMD sTRX4, which is not obvious… Although the pump will not cover the entire CPUIHS.
Fans
Who says watercooling kit in 360 mm, also says three fans in 120 mm. And for this, the company provides a trio of FK120 that we already met during the test of the AK500, a large aircooling fan.
Here, there are no surprises, as we once again find sober, not to say minimalist, fans. They offer a square frame, without embellishment with rubberized silent blocks at the four corners. The blades are nine in number, thin at the base, but rather wide at the tip. The curvature is also quite important. Finally, the power supply is done via a flat and black PWM cable of 25 cm length.
By looking at the data sheet, we learn that they benefit from a PWM power supply. Their speed range is between 500 rpm and 2250 rpm, so they are a bit faster than theAK500 mill. The announced airflow is 85.85 CFM and the static pressure is 3.27 mmAq.
Bundle:
As for the accessories, we find something complete since the brand offers :
- An assembly manual and a safety guide
- A backplate for Intel sockets
- A splitter to connect the three fans to a single socket
- Mounting arms for Intel and AMD platforms
- All the screws and bolts needed to install the kit!
Here, no big difference concerning the accessories part in front of the LS720. The main nuance will be at the level of the provided connectivity which disappears in favor of a Y for the connection of the fans. Here, the fans of the LT720 are not connected in series as was the case for its predecessor. On the other hand, the mounting elements are more neat since the mounting arms are completely black, so more discreet.
Roughly speaking:
With this LT720, we find a watercooling kit rather convincing on paper. Indeed, it offers a nice finish with a design that looks promising, especially in terms of lighting. Now we just have to see what it looks like on the installation side.
[nextpage title=”Installation and RGB”]
For the installation part, you’ll have to keep your AMD backplate, the manufacturer doesn’t provide one. If you don’t have one anymore, a quick look on eBay should allow you to find one easily.
Preparation of the pump
Before trying to assemble anything, we will have to start by preparing the pump. For this, we will simply screw the mounting arms corresponding to your platform: Intel or AMD. Here, nothing difficult, since they are fixed from the bottom of the pump with a Phillips screwdriver. On the other hand, a little surprise since the threads of the pump are magnetized, there is no risk of losing the screws if you slip during the operation!
Pump assembly
Once the pump is ready to be mounted on the CPU, it’s the motherboard’s turn to receive some preparations. OnIntel, you’ll have to start by removing the backplate from the back of your board and then turning the whole thing over. From the screw threads protruding around the socket, we will thread spacers, smooth in the case of an LGA-115x, ringed with the LGA-1700.
On the AMD side, you will have to remove the original mounting arms of the card to screw spacers on it. Be careful, the ones with the plastic base are for theAM4, the others for the sTRX4/sTR4.
Now that everything is ready, we can proceed to the fixing of the pump, for that, we remove the upper cover. This frees the access to the threads of the backplate on which we position the pump. Finally, it does not remain any more but to screw it via the nuts provided in bundle!
Finally, we proceed to the wiring, for this, we will need a three-pinaRGB header to manage the lighting of the pump. The pump itself connects directly to a socket AIO_PUMP on your motherboard.
All that’s left to do is to switch on and enjoy the pump’s lighting, which is frankly very successful. As you can see, several zones with infinite depth effects are present, in short, very nice!
[nextpage title=”Protocol”]
Small update of our test protocol. Indeed, we changed the software we were using to stress our configuration. The same goes for the different profiles. By the way, you will see that our configuration has recently received a new power supply. It is a RM750x from Corsair. Of course, we will always focus on temperature and noise measurements.
The wiring of the fans is not supported by our rehobus, so we set the ventilation manually via the bios of our motherboard. They will operate respectively with a PWM signal of 30%, 50% and 100%.
[nextpage title=”Speed and noise”]
Fan speed :
So we start our series of temperature readings. Here, we start from scratch. Let us specify the fan speeds recorded during our readings (for 12V, 8V, 5V):
As usual, we start by recording the operating speed of the three FK120s. In this respect, they display the most classic operating speeds forAIO fans. Indeed, we read some 2200 rpm at full speed, a little less than those of the LS720. Nevertheless, they will be faster at mid speed and at low speed. We’ll have to see what this means in concrete terms on the sound meter.
Noise:
As far as noise is concerned, the LT720 knows how to be discreet, especially at low speed where we noted 30.5 dB. However, if we push towards mid-range, the noise rises a notch and it becomes more audible than its predecessor the LS720 to end up being quieter at full speed!
Anyway, it is far from being the noisiest watercooling kit we have tested. This is a good thing for the future.
[nextpage title=”Temperatures”]
Processor at 65W
Despite a more violent 65W profile, this still represents the least stressful phase of this protocol. It allows to highlight the performances obtained with compact/entry-level heatsinks. These results are only indicative for the largest heatsinks (AIO, large dual tower heatsink, etc.).
Big surprise from this LT720 which, in 65W, manages to get to the first place, facing the H170i Elite Capellix from Corsair. DeepCool ‘sAIO is then equal in all its operating modes. It leaves all its competitors behind, even the LS720 , which is almost 2°C behind at low speeds.
Processor at 95W :
Here, our CPU will run at 3.90 GHz constantly and on all its cores. We apply a VCore of 1.375V to obtain a power consumption of about 95W. To simplify the reading of the graph, we may have rounded some values to the nearest integer.
With a power consumption of 95W on our Ryzen 7 1700X, we feel that the DeepCool kit does not demerit. Temperatures are again as good as the Corsair 420mm kit. Even at low speeds, the temperatures don’t take off that much. So you can afford to have a pretty beefy CPU while running your kit at low speeds, it’s very appreciable.
125W processor:
Finally, we finish with our 125W profile. Here the heat release is more important, let’s see how our coolings are doing!
At 125W, the LT720 once again makes it feel comfortable, even with an old overclocked octo-core CPU. The proof is that the processor does not even reach 61°C while the fan is running at low speed. As soon as you put the whole thing on full blast, you can reach 56°C. In short, a real walk in the park for the DeepCool kit!
Summary
Once again, DeepCool manages to offer us a very efficient AIO on the thermal level. As we have seen, it stands up to the Corsair H170i Elite Capellix, even though it is larger since it is 3x 140 mm! With this kit, you can afford tooverclock your processor without suffering too many consequences, especially sound. Likewise, you won’t be afraid to mount it on big power-hungry CPUs.
[nextpage title=”The temperature/noise ratio”]
On these graphs of perf/noise ratio, we remind you that the best is to be placed as much as possible on the bottom left of the graph. For the reading, the left most point symbolizes the 12V ventilation, the one in the center the 8V ventilation and the right most point the 5V ventilation.
With a CPU consuming 65W, we notice that the LT720 is positioned very aggressively. The kit offers a very good temperature/noise ratio, especially at mid-range, it does as well as a MEG CoreLiquid S360. Likewise, it will only make mincemeat of the H170i Elite Capellix.
In 95W, the DeepCool kit is more detached from the MSI kit. However, we notice a clear break in the curve from the mid-range. Beyond that, the curve shows an almost vertical profile. If your processor has a consumption of 95W, it is clearly useless to run the LT720 at full speed. We will reserve this scenario foroverclocking for example.
With a consumption of 125W, we feel that the LT720 is better exploited. The curve does not go to the moon as soon as you switch the ventilation to 100%. Again, the kit is in the lead, the H170i Elite Capellix from Corsair not being able to compete. Finally, its only competition will be the LS720 on its low speeds!
[nextpage title=”Conclusion”]
We are now at the end of this test of the DeepCool LT720. So, what is this model worth? We take stock of it.
A design as convincing as ever!
With this new LT series, DeepCool continues to offer us watercooling kits with a neat aesthetic… But even more on these models. Indeed, the pump cover evolves to propose several lighting zones with an infinite depth effect. Coupled with a qualitative RGB lighting, it can only give something very nice. Especially since the rest of the kit is well finished. It’s just a pity that the radiator is still so discreet. A more visible DeepCool logo might have been welcome to match the rest.
A simple assembly of the discrete elements!
We quickly come to talk about the mounting system proposed with these kits. In fact, it is identical to that of the LS series except for one… Not two details: the colors of the elements and the screw threads of the magnetic pump. The first one allows to make the kit more discreet once the pump is in place, the second one makes the assembly more pleasant by limiting the risks of losing screws.
On the other hand, it is a pity that the brand did not keep the possibility of connecting the fans in series. This would have facilitated cable management within the PC. In return, we have the right to a Y, centralizing the connection of fans on a single fan plug.
The same goes for the thermal paste, for an AIO of this range, a small syringe of paste would have been welcome, so we wouldn’t have to buy more after the first installation.
First class performance!
When we did the readings, we can say that this LT720 surprised us and in a very pleasant way. Thermally, it is positioned opposite the H170i Elite Capellix from Corsair. Despite its smaller size, it holds its own against this large model.
Noise levels remain under control, at least, we do not go into exaggeratedly high levels as with a Core Ocean T38 from Alphacool. However, the noise level at mid-range remains higher than its predecessor, the LS720 which uses different fans. But at low speed, it is silent, especially since the pump remains discreet at all levels.
Price too variable :
[gp_product_box ean=”6933412727927″]
Now only remains to talk about the selling price which is, officially, 144.90 € for this version in 360 mm. In fact, the bill will depend greatly on the store you turn to. In European Amazon, we are between ~145 € and ~165 € (depending on the retailer) and soon on Amazon.com.
Clearly, given the benefits, the positioning is very aggressive. As a reminder, an H170i Elite Capellix from Corsair is between ~230 € and ~300 € depending on the dealer. In short, no need to insist that the positioning is good!
DeepCool LT720
We like:
- The sublime design of its pump!
- The black mounting elements for more discretion
- The simple assembly to realize
- The silent pump at all speeds
- The silence at low speed
- The performance in all circumstances!
- The fact that it ranks at the level of a 420 mm despite its 360 mm format
- Consistent pricing
We liked less:
- The radiator a little (too ?) sober
- The absence of thermal paste in syringe
- Can be heard at full speed
In the end, we choose to award the platinum to this LT720 from DeepCool. As we have seen, the kit is very efficient without being extremely noisy, it holds its own against the H170i Elite Capellix from Corsair by being more compact. The design is very successful, even if the radiator is still too discreet and the price is consistent. Finally, we could reproach it for being supplied without a syringe of thermal paste and its noise a little pronounced at full speed… But for that, you just have to restrain it a little!
A big thank you to DeepCool !
