DeepCool was founded in 1996 in Beijing, China and is a favorite of many enthusiasts. They are well known for their air and water coolers and computer cases. They also offer fans, power supplies, and peripherals such as keyboards and mice. One thing I like about DeepCool is not only are they constantly striving to innovate to create products with higher cooling capacity – but they also push the performance/$ bar, providing products that don’t break the bank.
Today we’ll be looking DeepCool’s best performing liquid cooler, the 360mm LT720 cooler, and testing it with AMD’s Ryzen 7 7700X CPU.
Over the past few weeks I’ve been exploring different levels of cooling with AMD’s Ryzen 7 7700X CPU. When I tested EKWB’s AIO Elite 280, it surprised me by able to keeping the CPU under TJmax in intensive workloads – I had been under the impression that it was “impossible” to keep Ryzen 7000 CPUs under TJMax in intense workloads. On the opposite end, I tested BeQuiet’s Pure Rock LP SFF cooler – which was only able to cool 66W.
Introducing DeepCool’s LT720 WH, a white 360mm AIO Liquid Cooler
Packaging and Included Contents
Included in the package are
- 360mm Radiator
- Infinity Mirror CPU block with 4th Generation DeepCool liquid pump
- Pre-applied thermal paste
- 3x 120mm fan
- Mounting for modern Intel & AMD platforms
- Low noise PWM adapters
- 3-way fan splitter
- User Manual and Information Pamphlets
AM4 and AM5 Installation
Step One: Remove the default AM5 retention socket
Step Two : Attach mounting standoffs, then secure the mounting bracket
Step Three: Secure the cooler to the mounting bracket
Step Four: Attach the Infinity Mirror
Step Five: Secure the fan and radiator as appropriate to your case. Normally I would test an AIO with the radiator at the top, however on this case there is only room for a 360mm through the front. As you’ll see from the testing results, DeepCool’s LT720 performs well even in this orientation.
Features of DeepCool’s LT720WH 360mm AIO Liquid Cooler
Full RAM Clearance
As the CPU block doesn’t overhang the RAM in any way, all RAM sizes are supported when using this cooler.
Full Copper CPU plate with pre-applied thermal paste
DeepCool’s LT720 comes pre-applied with thermal paste to make the installation of the cooler simple. The CPU contact plate is made of pure copper for optimum heat dissipation and thermal transfer.
Accessible Refill Port
While you won’t ever need to worry about refilling the AIO during the lifespan of it’s 5 year warranty, if you ever do need to refill the unit there is an accessible port to do so.
High Performance 4th Generation In-house design AIO Pump
One of the most important factors in the performance and noise levels of a liquid cooler is its pump. Most coolers on the market use Asetek based designs – not but DeepCool designs their own pumps in-house. The LT720 features a 4th generation pump design with a three phase drive motor running at up to 3100 RPM to enable efficient and strong cooling capacity.
ARGB Infinity Mirror CPU Block
On top of the AIO pump rests an Infinity Mirror with aRGB header support.
3x DeepCool FK120 fans
DeepCool advertises the following with this fan:
- Designed With Precision
- Carefully constructed and tested to enhance static pressure and concentrate airflow for outstanding cooling performance on any mounting application including cooler heat sinks, radiators, and case fan configurations. The narrow frame bezel and wide fan blade provides increased surface area to deliver higher efficiency.
- Elite Cooling
- Extremely efficient with a PWM range up to 2250RPM that maximizes air pressure and airflow for impressive cooling results while offering dynamic balance between high performance and low-noise operation.
- Outstanding Details
- High-quality polybutylene terephthalate (PBT) material is used to ensure increased durability and wear resistance, allowing the fan blades to maintain high tensile strength. Shock-absorbing rubber pads shield the screw mounts to reduce unnecessary vibrations for stable operation.
Test Platform Configuration
- At the default power limits
- With a 95W PPT enforced
- With a 75W PPT enforced.
Default Power Limits
Well, that’s what we would be looking at if the CPU hit TJmax – but DeepCool’s LT720 was able to rise to the challenge of keeping the CPU under TJMax at the default power limits.
Keeping Ryzen 7700X under TJmax in a rendering workload is an impressive achievement on it’s own, but I didn’t expect the LT720 WH to beat EKWB’s AIO Elite by 2C and run quieter while doing so!
At 53 dBA this noise levels are on the louder end of things, but this sort of cooling capacity doesn’t come easy. Based on my previous testing results I have with Intel’s i9-13900K at Tom’s Hardware, which also includes results from DeepCool’s LT720 (black model), I think very few coolers will be able to offer this level of total performance.
Noise Normalized Results
Performance only scales by a limited amount with improved cooling capacity with Ryzen 7000. This also means that there is less of a benefit to running fans at higher performance levels. As such, it can be useful to see how coolers compared when noise normalized for quiet operation.
DeepCool taking the top of this chart didn’t surprise me after seeing the results of the stock power limits testing, but what really shocked me is how close the LT720 came to running the stock power configuration under TJMax while running at noise normalized settings for silent operation.
Ryzen 7700X will use ~135W maximum at the stock power configuration, so a result of 125W cooled while running completely silent is simply phenomenal! This means you can run the LT720 at silent settings and encounter virtually no performance loss in the most intensive workloads.
The results in this scenario are much like those in the full power test. DeepCool’s LT720 WH is again the best result I’ve seen in my limited testing on Ryzen 7700X. It runs audibly at this power level when tied the default fan curve of ASRock’s B650E Taichi, but not noisy in my opinion.
