DeepCool LT720 AIO: Unboxing and Closer Look
After a quick look at the front and back of the box, we’re greeted with a brown box with green accenting and a white cardboard sleeve clearly highlighting the model name and specifications, overall appearing clear and concise. This is taped to the brown box housing the cooler, giving it a nice contrast.
The LT720 cooler was packaged in this molded cardboard insert which was more than enough to ensure it arrived free of any damage. Two small foam inserts were on each end to provide additional padding. The pump housing, radiator, and fans all come in plastic covers. Our motto: “Don’t Bin: Please keep these in the box for future use and out of the landfill.”
An additional brown box inside the package includes the manual and accessories bag, with mounting kits for Intel 115x, 1200, and 1700 and AMD AM4 and AM5 sockets. A 4-pin fan splitter cable (to three headers) is included, along with some installation and warranty manuals.
A quick look at the LT720; here, we can see an Aluminium 360mm radiator painted black. It measures 402×120×27 mm. Sleeved tubes at 410mm in length lead to the header, pump, and Copper block housing. A curious choice is to use an Aluminium radiator with a Copper block, which highlights the use of corrosion inhibitors in the coolant mix.
DeepCool includes two plastic clips to keep the hoses neat once installed inside the case.
The radiator comes with DeepCool’s patented Anti-Leak technology. An elastic pressure-relief bag will be added inside the radiator, with one side exposed to the air and the other dipped in the coolant. When the internal pressure exceeds atmospheric pressure, the bag will be squeezed, thereby increasing the system’s internal volume. As a result, the increased pressure is released, and the risk of leakage is avoided. More HERE.
DeepCool includes a copper block with a pre-applied Thermal Compound on the LT720. This explains the missing tube, typically found in the accessory box.
It is taking a closer look at the pump housing, which DeepCool calls the multidimensional infinity mirror top cap. It’s angled to sit in one direction only, with the hoses at the bottom of the cover. Deepcool’s green logo can also be found in the lower left-hand corner of the housing.
A three-dimensional infinity mirror surface is revealed underneath the top cover, offering a new visual experience through a multi-faceted geometric reflection. The picture below will show you it has been installed and turned on.
The housing attaches to the pump magnetically and is mounted to the four corners you can see protruding from the accommodation. Looking at the pump, you can see the magnets on each corner.
DeepCool uses their 4th generation high-performance pump with speeds with a three-phase drive motor up to 3100rpm and improved micro-channel design to ensure optimal coolant flow.
The pump terminates using a 3-pin header to connect to the motherboard. A 3-pin 5v ARGB header is also used to power the ARGB LEDs in the housing; it also has a pass-through connector to attach to additional ARGB cabling.
DeepCool includes three FK120 fans with the LT720 AIO. These fans are 120x120x25mm in size, come black, and use anti-vibration rubber pads in the corners.
The FK120 fans are a 4-pin PWM fluid dynamic bearing fan with a speed rating of 500-2250rpm.
DeepCool LT720 AIO: Installation
DeepCool pre-mount the screws into the backplate used on Intel 115x, 1200, and 1700 socket motherboards. You slide them into two positions depending on the socket being used, inner for 115x and 1200 and outer for 1700. This makes the overall installation very simple and easy to do.
Put the suggested spacers over the screws. The 1700 socket spacers were needed in this case, but 115x and 1200 are also included.
Attach the mounting bracket to the pump. DeepCool provides Intel and AMD brackets in the box.
DeepCool uses small magnets around the screw threads in the pump housing, making it a lot easier to install the brackets. We’ve not seen this before, but we really like this addition!
Attach the pump block to the CPU mount using the four screws provided. DeepCool intends for you to mount the pump in this orientation with the hoses at the bottom.
Attach the infinity mirror top cap to the pump. As mentioned earlier, it easily slides onto the pump and is held in place magnetically. We are taking care to route the ARGB cable as neatly as possible. Pre-mount the three FK120 fans to the radiator and route the wires to the rear. We’d recommend doing this before you install the radiator for ease. Finally, the radiator is attached to the case. We opted for a push configuration in the case’s roof and used the smaller screws to mount the radiator flush to the roof panel.
DeepCool LT720 AIO: ARGB Lightshow
We like what DeepCool achieved with the ARGB effects in the multidimensional infinity mirror top cap. Being controlled directly from the motherboard, there are numerous options available. But we lit it up white to show it off as best as possible.
The overall aesthetic is great, and we like the lighting in each mirrored window in the top half to add contrast to the silver lower section and the DeepCool logo in the lower-left corner. It’s undeniably the showpiece of the LT720!
DeepCool LT720 AIO: Thermal Performance
It isn’t ideal for running Prime95 for a prolonged period, and if you get called away to do something, it could be left running for much longer than needed. We have decided to update the testing method for better and more consistent results. Our new methodology involves running a multi-threaded performance benchmark called Cinebench R23.
We’ve elected to use 50% and 100% fan speeds set in the BIOS to provide additional results and a dB measurement, with influences ranging in the +/-1.5 dB range with our equipment.
- CPU – Intel Core i5-13600K 5.1GHz P-core 3.9GHz E-core @ 1.3v
- Motherboard – Z790 AORUS Elite AX DDR5
- RAM – Kingston Fury Renegade 6800MT/s 32GB DDR5
- SSD – WesternDigital SN730 500GB NVMe
- PSU – Thermaltake Toughpower GF1 850w
- Case – Thermaltake Ceres 500 TG ARGB Black
- OS – Windows 11 Pro 64-bit
In addition to keeping our test setup consistent for all CPU cooling tests, we always use the same thermal paste rather than any that is supplied or pre-applied. Our thermal paste of choice is NT-H2 from Noctua.
Idle Testing Methodology
To test each cooler at idle, the minimum temperature is taken after leaving the PC, with only start-up programs being allowed to run for 5 minutes. This temperature is deducted from the current room temperature, and our final delta temperature is provided. The mean of three tests is recorded.
Load Testing Methodology
We run Cinebench R23 for 30 minutes to test each cooler under load using the multicore CPU stability test. This temperature is deducted from the current room temperature, and our final delta temperature is provided. The mean of three tests is recorded.
50% fan speed: 38 dB
100% fan speed: 48 dB
DeepCool LT720 AIO: The Verdict
It’s great to see decent thermal performance results from the LT720! It offers good cooling performance out of the box; trading blows with other 360mm AIOs. It looks great with its black aesthetic and comes with three decent FK120 4-pin PWM fans we’ve seen with other DeepCool coolers.
Noise levels were good, with the fans spinning up to 1300rpm at 50% at 38 dB and loud at 2250rpm at 100% at 48 dB.
As mentioned before, the presentation of the product itself is good, and that quality is evident throughout. The radiator and pump housing are solid, as are the braided tubes.
The mounting kit Deepcool has included works flawlessly and installs with ease.
The multidimensional infinity mirror top cap is undeniably the showpiece of the LT720’s aesthetic, and we like the finish and solid ARGB lighting effects. It’s a good time to mention that it has full support with MSI Mysticlight, ASUS Aura, Gigabyte RGB Fusion, ASRock Polychrome, etc.
Adding to its overall appeal is the £124.99 price at the time of writing. That makes this a pretty affordable cooler and one we can recommend, especially for its unique ARGB infinity mirror lighting effects.
You need to decide whether you want ARGB lighting or a couple of degrees cooler temperatures and go for the Arctic Freezer II 360 at the same price…
- Thermal performance is decent.
- The build quality is excellent.
- It’s priced to compete and does.
- FK120 fans are too LOUD at 100% fan speed.
Thanks to DeepCool for sending over the LT720 AIO for today’s review.
