DeepCool LT720 White Cooler Review: 360mm AIO

In this comprehensive review, we'll be unboxing, installing, and testing the DeepCool LT720 White so you can learn everything there is to know about it.

Review Summary

The DeepCool LT720 white edition is a perfect candidate for a white-themed build, particularly the pump top cover and its fantastic RGB lighting effects. This cooler means business as it provides a good value for the performance level, although the noise output is on the high side.

Pros

Cons

We have so far tested LS720 and LT520 from DeepCool in their new generation of liquid coolers. The LT and LS series use the same pump design. The only difference comes from the type of fans each series uses. The main distinctive feature in the LT series is the squarish pump housing cover that looks dope in person. The LT520 is a 240mm size cooler, whereas LT720 is a 360mm version, and we are testing the LT720 White cooler this time. The white edition speaks of itself in terms of overall aesthetics.

The LS ad LT series coolers are based on DeepCool's fourth-generation pump and FC/FK series fans. The block's cover is removable from the pump, and there is a three-dimensional infinity mirror surface underneath the top cover that offers a new visual experience through a multi-faceted geometric reflection. This cooler is compatible with the Intel LGA1700/1200/115x/20xx and AMD AM4 and AM5 sockets.

The cooler is shipped inside a cardboard box.

There is a white color flyer cover over the brown color cardboard box. The cooler features the Anti-Leak technology which was introduced with the Castle and Captain V2 series earlier. This cooler does not have RGB backlighting on the fans, unlike the LS series coolers.

DeepCool has emphasized the Anti-Leak technology on this side of the flyer. We have already covered this technology in detail in our previous DeepCool reviews; hence we won't go into the details this time. The specifications of the cooler are printed as well.

DeepCool has provided the accessories and cooler inside an eggshell. This prevents the contents from being damaged during shipping.

Let's see what is provided in the box by DeepCool.

There is a brown color box having all the mounting hardware inside.

There is a comprehensive user guide with instructions on how to install this cooler on the supported sockets.

DeepCool has provided a plastic-made Intel backplate. This backplate has pre-installed standoffs, which reduces the installation steps.

We have:

We have

There is a 3-way PWM splitter cable provided as well.

There are 3x Low Noise Adapter cables for the fans. Connect these to the fans first before using the PWM splitter cable.

The Deepcool LT720 is a 360mm CLC cooling solution. It has a 360mm radiator with three white FK120 fans.

This unit has an aluminum-made radiator. The complete assembly is white color spray painted. It has a dimension of 402x120x27mm. The 402mm length makes this cooler taller than many other 360mm liquid coolers we have tested. 27mm is the height of this unit. Installing 120x25mm fans would make the overall height to 54mm or so, including the heads of the screws. The radiator has a 20 FPI count. There is a gap of 105mm between any two fan mounting holes on opposite sides of this radiator. DeepCool has done a good job in fin stacking as we did not find any bend or broken fin.

The far end is a rectangular design. There are labels pasted over here. One seems to have a serial number for this unit, and removing it would void the warranty. This unit is rated for 0.38A at 12VDC. I am not sure about this current rating. It could be a safety current probably for the pump.

Looking at the tube side of this radiator, DeepCool has used clamps to conceal the connection between the tubes and fittings. There is no sticker or label on this chamber.

The right side of the radiator has a pressure release valve at the bulkhead side. Deepcool has installed an elastic-based pressure-released bag on the outlet side of the radiator. One side of this bag is dipped in the coolant whereas the other side is exposed to the air. When the internal pressure reaches the atmospheric pressure or exceeds it, the bag will be squeezed. This would increase the internal volume of the loop and would cause the increased pressure to be released in the air through the valve. This would reduce the risk of leakage in the AIO owing to the increased internal pressure.

Looking at the side of the main frame, we can spot a DeepCool logo on the near chamber. There is no other branding or text in the center.

There is no protective plating under the mounting sides of this radiator. This plating protects the fins from getting damaged due to excessive torquing. There is a certain distance between the fin stack and the frame of this radiator, meaning that the actual thickness of the fin stack is less than 27mm.

The soft tubing is made from an upgraded anti-explosion rubber tube manufactured using an anti-corrosion, crush-resistant, and thermostable material. The soft material tubing is flexible and doesn't produce kinking, which is always a plus. Deepcool is using mesh sleeves on the hoses to give them a clean look. The length of the tube is approximately 410mm.

DeepCool has provided two stylish covers for better handling of the tubes. There is DeepCool branding embossed on these covers.

Let's take a look at the main element of this cooler. It is the water block with the pump housing. We have a different outlook on the LT series compared to the LS and other generations of coolers from DeepCool.

The pump housing has a dimension of 94x60x88mm. The block on the LS series has a dimension of 85x74x57mm. Comparing both, we can see the block on LT has a relatively large size. The top cover is completely removable. There is a DeepCool logo on the cover. Though it seems like the cover is made of aluminum, it is not. The housing is white in color and has geometrical cutouts exposing the infinity mirror design. This design has a multi-faceted geometric reflection creating a 3D effect.

The above picture shows the side of the cover. We can gauge the ginormous size of the top cover sitting on top of the black color pump housing. There is no branding over here of any sort.

The above picture shows a front view of the cover and pump housing. There is a large size exposed window up top for light reflection.

Looking at the backside of the top cover and pump housing, we can see that the tubes and fittings are installed at a 90° angle to make these tubes rotatable (not fully). There are two flat cables coming out from the side over here.

We have a cable to power the pump's motor, and it has a 3-pin connector. The other cable powers the RGB LEDs and has standard RGB connectors (3-pin male and female connectors using 5V).

We have removed the top cover and are showing a cross-section of the sides on this cover, showing the area in which the lighting effect would come from.

The above picture shows the other sides’ cross-section view. We have exposure on three sides for some vivid lighting effects.

We can see a thick diffuser under the top cover and a LED strip comprising 6 digital RGB LEDs.

The above picture shows a pump housing after removing the top cover.

The pump has a rated speed of 3100±RPM which is higher than 2550±10% RPM on Castle V2 series coolers, at 12VDC rated voltage. Power consumption is 4.56 Watts using 0.38A current. The noise level is rated at 19 dB(A). The pump's LED power consumption is 3.15W using 5VDC voltage. The cooler has a three-phase drive motor up to 3100 RPM.

This unit comes with a pre-applied thermal paste at the copper base. This base has a size of approximately 53×53 mm. Notice the 4x mounting holes on the base surrounding the housing. This is where the mounting brackets are installed. DeepCool uses a thick copper base plate with a seamless match. Optimized microchannels are used in the design.

The LT720 comes with three FK120 white edition fans. These fans don't have RGB backlighting. These fans have a square frame that makes these fans look beautiful. Each fan has 9 black color blades. There is a gray color sticker on the center with DeepCool branding. The backside of a fan has a 4-arms assembly holding the blades and the center. The fans are made in China. One of the arms has widened body as it carries the power cable.

Each mounting corner has a cut-to-size anti-vibration rubber pad which is also white in color.

There are dotted arrow symbols on the frame showing the direction of airflow through the fans.

There is a single flat cable coming out of the fan that powers the motor of these fans. It has a 4-pin PWM connector.

The salient specifications of the fans are:

DeepCool uses standard RGB connectors on these fans and pump covers. This allows the digital RGB Lighting to be compatible with the majority of motherboard manufacturers’ supported motherboards. These include:

Here are some pictures.

This cooler was tested on the Intel platform using Intel i7 13700k over ASRock Z790 Steel Legend WiFi. Some key steps are:

This cooler has a dimension of 402 x 120 x 27mm without fans. With fans, this size is 402 x 120 x 55mm. We did not observe any clearance issue with this cooler. You would need to check that your PC Case has clearance for this size radiator. The tube side may not hinder the first DIMM slot.

We have used the below-mentioned configuration for this testing:

Here is the settings table for testing:

Before we move on to the results, let me write a few lines on the new platforms from both camps. We have seen AMD AM5 and Intel Alder Lake S CPUs taking more power, and this time both sides have aimed at reaching the maximum clocks regardless of the thermal limit. In fact, they run into thermal limits right away depending on the cooling solution and the clocks being used.

This has made testing of CPU coolers challenging because viewers/readers are not used to a new nomenclature which is what clocks are sustained under a given load using a particular cooler. That is if the cooler is capable of providing enough cooling head to sustain the high frequencies. Traditionally we are used to going the other way around, that is, which cooler is better in terms of thermal capacity. Despite this, we are using temperatures as a base for measuring this unit.

The ambient temperature was 29°C. The testing is done on an open-air bench system. Once inside the chassis, the temperatures are expected to rise and would largely depend upon the optimal airflow inside the chassis.

Disclaimer: Every silicon is different; hence no two same SKUs are likely to take the same voltage to yield the same performance at the same thermals per se, but the margin would be close. Not every stress test run may yield the same result, which could be due to various reasons like thermal paste application, ambient temperature variation, the mounting pressure of the cooler, etc. This is very why we have listed our variables and their settings. Variables not mentioned are on the Auto setting. We are actually testing the cooler on all Auto and stock settings.

Let's take a look at the results.

This test was done using Intel's default settings with power limits imposed. The CPU was drawing roughly 225W power, so this is a 220W domain result.

The maximum temperature under heavy workload was 89°C. Since we have used a different i7 13700k SKU than the one being used for regular testing, there is no other cooler in the graphs. But this is a good performance from the DeepCool LT720 White, given how these new platforms behave from a thermal point of view under heavy multi-core synthetic load. We have used pre-applied thermal paste.

As per our sound meter, these fans were making 53 dB(A) sound output at an ambient sound level of 33dB(A).

We have earlier reviewed the DeepCool LT520 cooler and found it to be a good performer in 240mm size coolers based on our experience in testing these coolers. This time we have tested LT720 white edition cooler from DeepCool. This is a 360mm size liquid cooler and we have got a beautiful white edition that would go hand-in-hand with the white-themed builds. This cooler uses DeepCool's fourth-generation pump powered by a 3-pole motor.

I remember DeepCool giving a specific focus on the block's orientation on the new platforms from Intel and AMD, particularly on the Intel LGA1700 platform. They suggested installing the block in a 6’0 clock orientation for better results. However, they did not specify this requirement on the LT series coolers, but since both series of coolers have the same pump and base design, the 6’0 requirement would still hold true for the LT series, in my opinion.

This unit has an aluminum-made radiator having a dimension of 402x120x27mm, where 27mm is the thickness of this radiator. Installing 120x25mm size fans would make the overall height to be 54mm approximately. The complete assembly is white color spray coated. The FPI count is 20. DeepCool is using Anti-Leak technology on this cooler as well. We saw that with their V2 of the Castle coolers. The soft tubing is made from an upgraded anti-explosion rubber tube manufactured using an anti-corrosion, crush-resistant, and thermostable material. The soft material tubing is a bit flexible and doesn't produce kinking, which is always a plus. Deepcool is using mesh sleeves on the hoses to give them a clean look.

The block on this cooler is the same as it is on the LT520 but differs from the LS series of coolers. There is a removable top cover that has digital RGB LEDs housed inside. The dimension of the pump block is 94x80x68mm. The block cover features a mirror infinity design which is further enhanced by using the multi-faceted geometric reflection creating a 3D effect overall.

While this seems pretty futuristic, the design is actually basic on the inner side of the cover. There is a geometric design placed under the diffuser. The diffuser runs on three sides. The pump has a speed of up to 3100 RPM ±0% which is further enhanced by using an improved micro-channel design and thick copper base. The unit has a copper base measuring approximately 53×53 mm. The power consumption of the pump is 4.56 Watts using 0.38A current. The noise level is rated at 19 dB(A).

There are three FK120 white editions provided in the box. These are non-RGB fans and they are finished in white color from head to toe. Their maximum rotational speed is 2250 RPM ±10% with a maximum airflow rating of 85.85 CFM at 3.27mmAq static pressure. The noise rating is <32.9 dB(A). The fans are using the Fluid Dynamic Bearings. There was no humming noise at full speed on these fans, which we observed on the LT520.

The installation is relatively simple, and we need 7 items to install the block on the CPU, which makes the installation efficient in terms of the total number of steps and the items required. The fans use 4-pin PWM connectors. The pump is powered by a 3-pin connector. The digital RGB lighting is powered by standard 3-pim, 5V RGB connectors. The use of standard connectors makes the life of a user easy as this solution is compatible with a majority of supported motherboards from major manufacturers. We tested the lighting effects using GIGABYTE RGB FUSION 2.0, and it was working fine.

DeepCool has mentioned that the MSRP of LT720 White and Black editions is USD 139. DeepCool is offering a 5-year warranty on this cooler. This is too good a price to beat; although the fans are not RGB, the performance of this cooler is very good. The overall noise output of the fans is high, so setting a custom fan curve is in order.

We are thankful to DeepCool for the provision of the testing unit.
