Gamers know that high-end CPUs run hot, which can impact gaming performance. And installing random coolers may not function well under heavy workloads or produce annoying noise. But with DeepCool LT720, there is no such problem.
Its powerful fourth-generation pump and distinctive infinity-mirror design are built to give demanding processors the cooling headroom they need. But impressive specifications do not automatically make a cooler worth buying.
So, how well does the LT720 actually perform, how loud does it get, and who should consider it? Let’s find out.
What is DeepCool LT720?
The DeepCool LT720 is a 360mm liquid CPU cooler built around DeepCool’s fourth-generation in-house pump design. The pump uses a three-phase motor capable of reaching 3,100 RPM and works with a thick copper cold plate and optimized microchannels to move heat away from the CPU efficiently.
The radiator
- Measures 402 × 120 × 27mm
- Paired with three 120mm FK120 PWM fans.
Each fan can reach up to 2,250 RPM and produces up to 85.85 CFM of airflow and 3.27 mmAq of static pressure.

The specifications above are based primarily on DeepCool’s current LT720 specification page.
1. Cooling Performance
Tom’s Hardware tested the LT720 with Intel’s Core i9-13900K and found that the cooler could handle an average CPU load of around 315W in its Cinebench R23 testing.
The LT720 also maintained its strong position when the processor was restricted to 200W. Tom’s Hardware reported that it remained about 3°C ahead of its closest competitor in that test. At 125W, it continued to deliver excellent thermal performance.
This means the LT720 has considerably more cooling capacity than you need for many mainstream processors.
It makes the most sense with high-end CPUs that can consume substantial power under sustained workloads, such as high-end Intel Core and AMD Ryzen processors.
For gaming, the extra cooling headroom can also help maintain lower temperatures during long sessions, particularly when paired with a high-power processor.
2. Noise Levels
The LT720’s noise performance depends heavily on fan speed. DeepCool rates the FK120 fans at up to 32.9 dBA, while the pump is rated at 19 dBA.
At lower power levels, the fans can operate much more quietly. Tom’s Hardware found the LT720 relatively quiet at the 125W setting, while other testing also found good noise performance at lower fan speeds.
3. Radiator and Case Compatibility
The LT720 uses a 402 × 120 × 27mm radiator. With the 25mm-thick FK120 fans installed, the radiator-and-fan assembly is approximately 52mm thick.
Therefore, your case should support:
- 360mm radiators
- Approximately 402mm radiator length
- 120mm radiator width
- Around 52mm total radiator-plus-fan thickness
Front mounting generally requires additional attention to GPU clearance. Top mounting can also work well, but you should check clearance between the radiator, motherboard heatsinks and RAM.
4. Infinity-Mirror Pump Design
The pump block is one of the LT720’s most distinctive features.
Instead of using an LCD display, DeepCool uses a three-dimensional infinity-mirror design underneath the pump’s top cover. Addressable RGB lighting creates a layered geometric effect that makes the pump appear deeper than it actually is.
This is particularly useful for builders who want premium-looking 360mm AIO CPU coolers without paying extra for an LCD display. The lighting can synchronize with supported motherboard RGB software.
5. ARGB and Software
The LT720 has addressable RGB lighting on the pump block. The FK120 fans included with the standard LT720 are performance-focused PWM fans rather than RGB fans. DeepCool lists the fans without lighting, while the pump uses a 3-pin 5V ARGB connector.
This has two advantages.
- First, there is no need to pay for RGB lighting on every fan if you prefer a cleaner build.
- Second, users who want full RGB fans can replace the included FK120s with their own ARGB-compatible fans.
The downside is that someone buying the LT720 specifically for an all-RGB setup will need to purchase additional illuminated fans.

Is the DeepCool LT720 Worth Buying?
Yes. The cooling performance of the DeepCool LT720 has been particularly impressive in high-power CPU testing. If your priority is strong CPU cooling without paying for unnecessary features, you should purchase it.
Who Should Buy the DeepCool LT720?
The DeepCool LT720 is a good choice for:
- High-end gaming PCs
- Users running high-power Intel processors
- Ryzen 9 systems
- CPU overclocking or high sustained workloads
- Workstations that need substantial CPU cooling
- Builders who want a premium pump design without an LCD
- Users who already have their own preferred RGB fans
- PC builders looking for a high-performance 360mm AIO
It is less attractive for:
- Compact PC builds
- CPUs that do not require 360mm cooling
- Users who want an LCD pump display
- Users who want RGB fans included
- People who prioritize extremely quiet operation at maximum performance
Final Thoughts
The DeepCool LT720 is a performance-first 360mm AIO that puts cooling capacity ahead of flashy features.
Its fourth-generation 3,100 RPM pump, 360mm radiator, and high-pressure FK120 fans give it substantial thermal headroom. The infinity-mirror pump also gives the LT720 a distinctive appearance, while the broad AM4, AM5, LGA1700 and LGA1851 support makes it suitable for a wide range of modern systems.
However, the fans can get loud at maximum speed, and the included fans have no RGB lighting, which are considered to be its main weaknesses.
