DeepCool LT360 Vision vs Cougar LQX Pro and Montech CyberFlow: 360mm AIO Tested

DeepCool’s LT360 Vision ARGB makes the strongest case in this three cooler comparison: it combines the lowest noise at full speed with the best thermal results in the tests. Cougar’s LQX Pro 360 ARGB comes close on performance and adds a large square screen, while Montech’s less expensive CyberFlow 360 Core/ARGB struggles to justify its much louder fans with cooling results.

The test compares cooling, noise, installation and design. All three are 360mm liquid coolers, but their feature sets differ: DeepCool and Cougar put a display on the pump block, while Cougar and Montech also include a fan aimed at the motherboard’s power delivery area. The test results make clear that extra hardware and high fan specifications don’t guarantee a better result.

Three designs, three different priorities

Cougar LQX Pro 360 ARGB

Cougar’s main visual feature is a 3.95-inch IPS-TFT LCD, with a square 720 × 720 resolution, 60Hz refresh rate and stated brightness of 350 nits. It can show system information or custom images, animations and video. The pump head also incorporates a VRM fan, intended to direct air over the motherboard’s power delivery components.

The 397 × 120 × 27mm aluminium radiator uses 400mm tubing. Cougar rates the pump at 3200 ±10% RPM and lists support for Intel LGA 1851 and 1700, plus AMD AM5 and AM4. Its three 120mm VRX120 fans use fluid dynamic bearings and run from 0 to 2500 RPM, with maximum ratings of 65.2 CFM airflow, 4.35 mmH₂O pressure and 33 dB(A) noise. The cooler’s stated capacity is 350W.

Installation was quick, and no extra control hub was needed. The review found the cooling respectable, but the VRM fan’s speed is tied to the pump, limiting separate noise adjustment. Cougar’s 7.5/10 rating reflects a capable, feature-rich option, though the review describes it as more expensive than some lower-cost screen-equipped coolers.

DeepCool LT360 Vision ARGB

DeepCool gives the LT360 Vision the largest display here: a 4.5-inch IPS panel with 854 × 480 resolution. Its viewing angle can be adjusted by 90 degrees, making it easier to orient the screen in a case. The pump uses a sixth-generation design with a three-phase, six-slot motor and field-oriented control. Its maximum listed speed is 3400 RPM.

The aluminium radiator measures 402 × 120 × 27mm and connects through 410mm tubes. Three 120mm ARGB fans operate between 500 and 2500 RPM, with up to 75.33 CFM airflow and 2.41 mmH₂O static pressure. DeepCool lists maximum fan noise at 33.66 dB(A). The review praised the solid construction, straightforward installation and combination of good thermal and noise results. Its reservations were imperfect RGB effects and several visible wires around the CPU block. It scored 8/10.

Montech CyberFlow 360 Core/ARGB

Montech’s model is available in black or white and includes a magnetic VRM fan. Its 397 × 120 × 32mm aluminium radiator is thicker than the other two listed here, and its pump is rated at 3500 ±10% RPM. The three E25 fans reach 2700 RPM, with maximum figures of 92.37 CFM airflow and 7.24 mmH₂O static pressure. Montech specifies a six-year warranty and compatibility with Intel LGA 1700 and 1851 and AMD AM4 and AM5.

Those headline fan figures come with a clear acoustic trade-off. At maximum speed, the fans are loud, and the VRM fan adds to the noise. Its speed is linked to the pump, so reducing that fan’s noise also requires lowering pump speed. The review found installation easy and praised the low price, but reported weaker cooling than comparable 360mm models. Montech receives 6.5/10.

Test setup and performance

The coolers were tested on an open bench with an AMD Ryzen 9 9950X, an ASRock Phantom Gaming X870E Nova WiFi motherboard, 32GB of G.SKILL Trident Z5 RGB DDR5-6000 memory and an MSI Radeon RX 6600 XT Gaming X. The system also used a 1TB Corsair MP600 Elite PCIe Gen4x4 NVMe SSD, a Seasonic Prime TX-1600 power supply, Arctic MX-6 thermal compound and Windows 11 Version 24H2.

Testing used a 30-minute Cinebench R23 loop, with steady-state CPU temperature taken from the final part of each run. The review compared full fan and pump speed with operation normalised to 40 dBA, and also checked AMD Precision Boost Overdrive (PBO) behavior. Each cooler was remounted at least twice, typically three times, to reduce the chance that a poor installation would skew the results. Room temperature was controlled around 19–20°C, and reported temperature deltas account for ambient conditions.

At full speed, DeepCool registered 46 dBA, Cougar 48 dBA and Montech 59 dBA. The temperature deltas followed a similar ranking: 59°C for DeepCool, 60°C for Cougar and 67°C for Montech. In other words, Montech was both the loudest and the warmest in this comparison, while the one-degree gap between the other two is small.

At a matched 40 dBA, DeepCool recorded a 63°C delta and Cougar 64°C. Montech rose to 74°C, an 11°C difference from DeepCool. PBO testing showed both DeepCool and Cougar averaging 5.25GHz, compared with 5.11GHz for Montech. DeepCool’s CPU temperature delta in that test was 64°C; Montech reached 70°C.

Which one makes sense?

DeepCool is the clearest pick for buyers who want a screen-equipped 360mm cooler and care about the balance between noise and cooling. Cougar is close enough in both temperature and PBO clock speed to remain a sensible alternative if its LCD and VRM fan appeal, though the fan-speed link is a compromise. Montech’s low price is its strongest point, but the tests show that its high-speed fans do not make up for its weaker cooling. For this group, the LT360 Vision leads on measured performance, with Cougar close behind and CyberFlow trailing.
