In today’s article, we are reviewing the COUGAR Poseidon Vistek Pro ARGB 360 in detail, examining its specs, design, installation process, and features to determine whether it’s a solid pick compared to the alternatives.
COUGAR’s Poseidon Vistek Pro ARGB 360 is a liquid CPU cooler with a customisable LCD screen. This AIO (all-in-one) cooler features a 360mm fan unit, which offers an interesting way to display RGB. It has a 3.95-inch screen for showing videos or system information, and it also comes with an interesting extra that lets you spice up your build.
Specification
The COUGAR Poseidon Vistek Pro ARGB 360 is a 360mm liquid AIO cooler with relatively standard dimensions. Most 360mm radiators are about 400mm long, 120mm wide to accommodate 120mm fans, and 27mm thick, and this cooler adheres to that standard. This particular cooler model comes in two sizes (240mm and 360mm) and two colours (black and white). COUGAR has also released another model, the COUGAR Poseidon Vistek ARGB, available in the exact two sizes and colours.

This cooler comes pre-installed with the Cougar’s UNITY 360 ARGB fans, a single fan unit comprising three fans with fluid-dynamic bearings. These help keep your PC’s overall noise levels down thanks to their non-contact design, resulting in less vibration. They also boast excellent airflow, with a max speed of around 2500 RPM. The pump’s speed is also looking impressive, with a maximum of 2700 RPM.
This cooler supports the latest Intel and AMD socket variants. Although AM5 and AM4 technically use the same mounting, it’s good to see them supported here. The Poseidon Vistek Pro also supports the latest Intel LGA 1851, a welcome sight.
Its pump uses a 3-pin DC connector, meaning it operates at a fixed voltage rather than PWM-controlled speeds. Fan control is handled via standard 4-pin PWM headers, allowing for dynamic speed adjustment based on system load.
COUGAR Poseidon Vistek Pro ARGB 360 Design
The COUGAR Poseidon Vistek Pro ARGB 360 is a bold entry into the high-performance cooling scene, pairing aggressive thermal engineering with a splash of visual customisation. Visually, it fuses a modern, industrial aesthetic with personal flair. At the heart of its cooling design is a robust copper cold plate, enlarged by 21% to maximise contact with today’s thermally demanding CPUs. This expanded surface area ensures efficient heat dissipation at the source, supporting both thermal stability and overclocking headroom.
COUGAR’s UTTERIGHT radiator architecture pushes conventional boundaries with precisely contoured fins angled at 90 degrees. This geometric refinement increases the heat transfer surface area, driving peak thermal efficiency beyond that of traditional layouts.
Cooling airflow is handled by Cougar’s pre-installed UNITY ARGB fans, which blend high static pressure with programmable lighting effects. These fans are tuned for performance but don’t shy away from aesthetics, syncing seamlessly with the rest of the system’s RGB ecosystem. The UNITY fan unit has a neat RGB strip running lengthwise down both sides.
Front and centre is the 3.95-inch IPS TFT LCD display, a standout feature that elevates the Poseidon Vistek Pro beyond mere functionality. It’s one of the largest flat-screen CPU coolers we’ve seen here at GeekaWhat. It has a crisp 720p resolution, a 60Hz refresh rate, and 300 nits of brightness. The screen delivers sharp visuals whether you’re monitoring component temperatures or showcasing custom animations. The screen can also be detached, adding flexibility for builders who prefer a cleaner loop or want to reposition the display.
Customisation of the screen’s content is managed via the COUGAR LCD Editor, found on their product page. The software allows users to personalise the screen with real-time system metrics, branded content, or dynamic visuals, making the cooler not just a thermal solution, but a canvas for expression.
Cooler Performance
Every CPU cooler we review is thoroughly tested within builds and a series of synthetic benchmarks. This provides performance data for each cooler, showing how it copes with gaming and multi-core workloads. The Intel Core i7-14700K is known to run hot, with a maximum operating temperature of 100℃. This is why our benchmarking system has an Intel Core i7-14700K at its core, with four 140mm fans to maximise airflow. Each cooler is set to the default fan curve mode in the BIOS, or we use an equivalent fan curve with the cooler’s software, so that testing is fair. All the data we collect is gathered from benchmarks in Cinebench and CPU-Z, with HWMonitor running in the background to record temperature information.
Cinebench 4-Thread
Our Cinebench 4-thread test simulates a typical gaming workload and gives us an idea of how the cooler will likely handle gaming, as most games use between two and four cores at peak. As we can see from the results, COUGAR’s cooler sits in the middle of the graph with a 65°C average and a maximum of 67°C.
Cinebench 8-Thread
The Cinebench 8-thread benchmark is more challenging than the 4-thread test, as it simulates slightly more intensive tasks such as photo editing, light video encoding, 3D modelling previews, or multitasking with several active applications. In the 8-thread benchmark, the Poseidon Vistek Pro ARGB 360 offered an average cooling output of 73°C, and it maxed out at 79℃. Compared to the other 360mm liquid coolers we’ve tested, this puts it nearer the bottom of the leaderboard, but it’s still a perfectly plausible choice for such workloads.
CPU-Z 8-Thread
CPU-Z 8-Thread is our most intensive test, designed to assess stability and throttling by running the CPU at a fixed speed for an extended period. This time, the Poseidon Vistek Pro ARGB 360 performed slightly better, averaging 72°C, but it shines with its maximum temperature reached of 75°C. This means that the cooler can handle steady CPU temperatures better than random spikes in temperatures. The Intel Core i7-14700K draws a lot of power, meaning it will get very hot. Paired with our results, we can say this cooler would be a sound pick for any mid-range or mid-to-high-range build.

Summary
The COUGAR Poseidon Vistek Pro ARGB 360 is a visually ambitious cooler that combines good thermal engineering with standout design features. Its detachable 3.95-inch LCD screen adds a layer of personalisation that will appeal to builders who care about both performance and presentation. The UNITY 360 ARGB fan unit and UTTERIGHT radiator architecture show clear intent to push performance boundaries, even if the results don’t always lead the charts.
In our benchmarks, the Poseidon Vistek Pro delivered mid-range thermal performance in Cinebench 4-thread and 8-thread tests, with slightly stronger results in the CPU-Z sustained load scenario. While it doesn’t outperform the top-tier coolers in raw thermal output, it maintains stable temperatures across gaming and content creation workloads, especially when paired with a well-ventilated case.
At $149, the pricing is on the higher side but still competitive when you consider the build quality, screen integration, and broad socket compatibility. The software experience is refreshingly minimal, though the screen’s reliance on the app for activation may be a minor drawback for some users. This cooler is best suited for mid-to-high-range builds where visual impact and modular flexibility are just as important as thermal headroom. It is not purely about performance, and that is part of its appeal. The Poseidon Vistek Pro ARGB 360 earns its place in the enthusiast space by offering a thoughtful mix of style, functionality, and smart engineering.
Unless the screen is a must-have for your build, there are stronger, more thermally capable options available at this price point. I wouldn’t recommend it for enthusiast-grade systems, but if you have a theme that fits, equipping your rig with this cooler is justifiable.
Pros
✅ Straightforward installation
✅ Pre-installed fan unit
✅ Broad range of customisations
Cons
❌ No pre-applied thermal paste
❌ Mid-tier performance
