The 360mm Ice Giant that Keeps Your CPU Cool and your PC Quiet

Reviewed by Rounak Roy


For quite a while we have been dealing with Deepcool. Deepcool formed in 1996 have been on the forefront of delivering affordable yet pretty powerful cooling solutions that can rival even the heavy weight cooling solutions out there. The company focuses mainly on cooling products like AIO's and cases but in recent years they have ventured in other markets like Peripherals, power supplies with well-known OEM’s like Seasonic, CWT etc. In today’s review we will take a look at the Deepcool LS720 which was sent over by Deepcool India for this review.

Note: I would like to clarify that because of some electrical issues with my system the FC120 Fans in the AIO were not working/died so I had to resort to the FK120 fans I had reviewed before here. The performance will be unaffected as both of them are similar minus the RGB.


The cooler comes in the new Deepcool packaging which includes a cardboard box adorned with a white envelope that has all the important details a person would need to know before purchasing. Unlike other companies Deepcool went with a simple yet informative outer packaging.

The front of the box has the product image and model. The back of the box houses all the specifications and certification labels. Both the left side and right side are blank with the Cyan Blue-green DeepCool branding.

The inside of the box has a recycled mashed paper insert that is molded to the shape of the cooler to save it from damage in transit. The mounting hardware and all accessories are placed in a small cardboard box on the side. Inside the box you will find the Manual, Mounting hardware and screws for AMD and Intel, a Deepcool extender for the FC120 fans, a sata+argb cable to power the fans and rgb, AIO tube clips and a extra faceplate to incorporate your own stickers on the pump face.


The Deepcool LS720 is not a 720mm cooler but rather its a 360mm cooler. Like most other Deepcool AIOs it comes with a Aluminium radiator which is 27mm thick. The fins per inch (FPI) density as measured by me came to around 24.5 which is a good thing considering my older Cooler Master AIO that died had a 23 FPI density. Since this a black cooler all the fittings are also black and the tube is long and covered by a mesh. Unlike other brands Deepcool AIOs in recent times come with Anti Leak technology which is a pressure regulating rubber valve which eases pressure on the fitting joints.

Deepcool has started to incorporate a more squarish pump block design which refreshing to see especially when they always used to provide round blocks earlier. The face has a kind of an infinity mirror look to it. The pump is the new 4th generation high-performance pump running at 3100RPM made in house by Deepcool. The wiring for the unit enters the pump from the side side the tube is on. The coldplate is made of copper and had minimal to no machining marks. The ARGB fans are the tweaked version of the FC120 ARGB fans which feature a Fluid Dynamic Bearing. The RPM and Airflow on these is slightly higher than the FC120 found on the store shelves.



The following system was used for testing:

For synthetic stress tests I used was the Cinebench R23, AIDA64 Extreme CPU+FPU+Cache stress test. I also took temperature readings in some of the games that I had installed. Overall the LS720 showed pretty positive results. The ambient temps were 30 Degree Celcius, it was the peak summer with outside temperatures hitting 42C so I was waiting for a rainy day and as a reult I had to delay the review a bit.
Coming to the readings you can see that the temps in AIDA64 is a bit higher than Cinebench but that is quite normal as AIDA64 FPU stress uses AVX instructions which pushes the CPU beyond its safe limits. Since most of the people will use the PC for rendering and gaming I have added the Cinebench and some Game temperature benchmarks.
I borrowed a Deepcool Castle 360 EX A-RGB to compare the temperatures in games. You can see that below in the graphs.


The Deepcool LS720 is a 360mm All in One Liquid cooler and performs pretty well even in summer time.
I have added some pointers below to better conclude the review.

Now, the performance of the cooler exceeded my expectations as can be seen in the graphs. On a AVX stress test it kept the CPU under 65C in Indian summer. Ease of installation and cable management was also a breeze thanks to the new Daisy chainable Deepcool FC120 Fans.
In general, the DeepCool LS720 is a good all-in-one liquid cooler it has a perfect balance between decent performance and attractive price. Keeping in mind the performance I can ignore the some of the small shortcomings which may vary from system to system and will rate the cooler as a worthy holder of the Tech Reprise Gold badge with a rating of 9/10.
