Another interesting AIO has reached our labs, this time from DeepCool, a company we have worked with before, quite some time ago in 2017! Their LT720 is the high-end 360mm offering with 3 120mm fans, an advanced 4th generation performance pump with a three-phase motor up to 3100RPM and improved microchannel design, while the pump cover is fully removable, RGB enabled and offers an unique “infinite” visual experience.

 

The AIO is shipped inside a medium-sized cardboard enclosure , which shows a photo of the product right on the frontal area:

 

 

 

On the back, we will note some product highlights, along with the full technical specifications, the supported RGB systems but also the respective serial number:

 

 

 

The AIO is protected inside via a custom cardboard mold, but also with foam material on the sides:

 

 

 

 

The fans are individually packaged, while the extra bundle is present in a separate, smaller cardboard box:

 

 

 

The fans are optimized for high pressure, with a dynamic PWM range between 500 and 2250RPM, a maximum airflow of 85.85 CPM, while the static pressure recorded is 3.27 mmAq:

 

 

 

The corners of the fans do include a rubber layer, to help with eliminating noise and vibration:

 

 

 

On the exterior, the fans preserve a square design, something that we haven’t seen before with other models:

 

 

 

On the back, the fans include a secondary sticker, with the product code name and the power rating, which is 12V at 0.22A:

 

 

 

Each fan is powered by a 4-pin PWM connector:

 

 

 

Let’s open up the smaller box and check out the inside contents!

 

 

 

We will get brackets for all available sockets, spacers, stand offs, thumbscrews, an adapter for connecting all three fans from the same header, screws for installing the fans onto the radiator but also screws for attaching the radiator onto the case and some low-speed fan adapters. These low-speed fan adapters remind us of Noctua fans, which had these always included in the box; with the adapters attached, the fan speed will be limited to a maximum of 1600RPM:

 

 

 

The supplied envelope does include an Information and Support leaflet, but also a Quick Installation Guide:

 

 

 

 

We will proceed with installation on the LGA1700 socket of our test system, so we accessed the Intel mounting bags:

 

 

 

The LGA1700 spacers are carefully marked for easy identification:

 

 

 

The backplate screw can be moved in different positions, depending on the socket we are working with:

 

 

 

 

Here is a look at both pump assembly and the radiator:

 

 

 

The radiator comes with a length of 402mm and a width of 120mm, while the height is set at 27mm:

 

 

 

 

It is equipped with an anti-leak system in order to regulate the pressure inside the rad; the user should not fiddle with this part because it will also void the warranty:

 

 

 

The opposite area comes with a nice DeepCool logo:

 

 

 

The tubing length is 410mm, enough for all types of install and we will also note some pre-installed tubing clips, to obtain a nice overall look of the setup!

 

 

 

The pump comes with a mirror on top in order to give out an infinity effect, which looks really cool, in RGB!

 

 

 

The cover is kept in place with magnets and it is very easy to remove:

 

 

 

Here is a closer look at the magnets on the pump:

 

 

 

On the bottom we will note the copper cold plate, which is also protected by a plastic cover:

 

 

 

The tubing fittings can be moved/rotated to help with the mounting position:

 

 

 

The pump connects to the respective motherboard header via a 3-pin connector:

 

 

 

Here are some additional views of the pump cover; due to its design, it supports installation in a single position:

 

 

 

 

 

 

A look at the bottom does show the RGB row of LEDs, but also the cut-outs which do allow install in a single position:

 

 

 

The first installation step would be to attach the backplate in the right position:

 

 

 

Afterwards, we will attach the dedicated spacers onto the screws:

 

 

 

The screws for fixing the fans and the radiator onto the case must be located next:

 

 

 

Mounting the fans is an easy process, but note the orientation of the cabling in order not to be forced to re-do the process after the radiator has been mounted onto the case:

 

 

 

The radiator should then be installed onto the case, with the smaller screws:

 

 

 

DeepCool has pre-applied a layer of thermal compound onto the cold plate, in order to ease the installation process; we will also have to mount the brackets in the designated areas, by using four small screws. What we did like was the fact that the screws are attracted to the threaded holes with magnetic force, simplifying the process when using the screwdriver:

 

 

 

The installation of the radiator does require two hands at first, at least until we fix it on the main corners, so it would be able to hold its own weight; we will have to use 12 screws for this process:

 

 

 

Next, we will get hold of the four thumbscrews, for fixing the pump onto the CPU:

 

 

 

There is enough space to work with when the top cover of the pump is removed:

 

 

 

The pump comes with a PWM connector, which should go to the CPU_OPT header on the motherboard; the 3-fan splitter will be connected to the three fans and the other end to the CPU_FAN header:

 

 

 

The top cover snaps in really easy, thanks to the magnets; in the presentation manual, DeepCool is showing the installation with the tubing right under the GPU, but we felt that the standard install with the tubing on the right looks better overall. Due to the inability to rotate the cover in a different position, it will be orientated to the left:

 

 

 

After connecting the cover to a 5V ARGB header on the motherboard and starting up the system, we noted the nice-looking infinity effect!

 

 

 

 

Test Setup:

 

CPU: Intel i7-13700K @ Stock

CPU Cooler: Currently tested AIO

Motherboard: BIOSTAR Z790 VALKYRIE

RAM: Sabrent Rocket 2x16GB DDR5 4800

Video: XFX Radeon 7900 XT

Power Supply: Corsair RM850

SSD: Silicon Power US70 1TB PCIe 4.0

Case: Cooler Master ATCS 840

 

We have performed the IDLE-Full Load temperature test with the help of the AIDA64 Stress Test module, while recording the temperatures in detail via HWINFO64 utility. The ambient temperature during testing was kept at a steady 23.5 degrees Celsius and the performance profile in our Windows 11 Pro 22H2 installation was set at default (Balanced).

The second part of the test included the HWBOT X265 4K Encoding workload, which is more stressful via AIDA64 one, which we did run two times and recorded the maximum temperature.

 

 

Here are the detailed Noise / Fan RPM results of the whole assembly; our fan header from the BIOSTAR Z790 VALKYRIE was set a Custom profile, due to no dedicated controller for the fans as in CORSAIR AIO tests. The test results will vary depending on the fan curve set on a specific motherboard. During the tests, the ambient noise was 31.1 dBA, while the sound meter was placed one meter away from the test system; the side panel was removed in this test stage.

 

 

The LT720 from DeepCool really impressed us in terms of ease of installation, the cool lighting effects of the pump cover (driven by the motherboard utility) but also regards to its performance. The AIO from DeepCool is trading punches with the other heavy hitters with the fans running at about 1670 RPM, so we get about the same performance for less noise levels (40.5 dBA), while using the same fan curve as with the other models which do not come with a dedicated controller.

 

In our tests, we noted that the fans could rotate with a maximum speed of 2102 RPM, but this aspect increased the noise levels to about 46.1 dBA, but we consider it is not really worth the effort since the default performance is excellent!

 

You may ask if we have found any negative point about this product; there is only one and it is not performance related! The pump cover can sit in only one position and if we do place the pump with the tubing in the standard position (with the fittings on the right), the cover will appear rotated to the left, so the DeepCool logo will be rotated as well.

 

The LT720 can be found online for about 126 Euros, a good price considering the advantages of this particular model!
