Who it fits
Good fit for
This cooler suits enthusiasts who prioritize visual customization alongside cooling power. The large LCD screen appeals to users who want to display wallpapers, videos, or system stats directly on the pump head. The high pump speed and 310W thermal rating make it suitable for high-TDP Intel and AMD processors. If you prefer all-metal mounting hardware for durability and enjoy ARGB lighting that syncs with your display, this model fits your setup. It is ideal for cases that can accommodate a 360mm radiator and have the necessary USB 2.0 header for the software.
Who should skip it
You should look elsewhere if you do not want to manage software. The display requires the 'Ocypus Display' software, which must be downloaded from the official website and added to your system whitelist. This adds a layer of maintenance that some users may find unnecessary. If you prefer a plug-and-play experience without custom themes or video playback on the cooler, this unit may feel like overkill. Additionally, if your case cannot fit a 360mm radiator or you lack a USB 2.0 header, this cooler will not work for you.
Verdict: The Ocypus Sigma PRO L36 BK offers a blend of high thermal capacity and extensive visual customization. It is a strong choice for users who want a statement piece that also handles high-TDP processors.
Key specs explained
Pump Speed: 3100 RPM
This rating indicates the maximum rotational speed of the internal pump motor. Higher speeds generally move coolant faster through the radiator and cold plate. This helps transfer heat away from the CPU core more efficiently. You should consider this if your processor generates significant thermal output. It ensures the water cooling loop remains active even under heavy computational loads, maintaining stable temperatures during intensive tasks.
Thermal Capacity: 310W
This figure represents the maximum thermal design power the cooler is rated to dissipate. It suggests the unit can handle high-performance processors that draw substantial electrical power. When shopping for AIO liquid cooling, compare this against your CPU's TDP. Selecting a cooler with a capacity exceeding your processor's requirements provides a safety margin. This helps prevent thermal throttling during sustained workloads or overclocking scenarios.
Display Size: 3.5"
This measurement refers to the diagonal size of the LCD screen on the pump head. A 3.5-inch display offers ample space for visual customization. You can use this area to show system metrics, custom images, or animations. It serves as a focal point for your build aesthetic. When comparing options, larger screens typically provide better readability. This size allows for detailed graphics without requiring excessive case space for the pump module.
Display Resolution: 640x480
This specification defines the pixel count of the integrated LCD screen. A 640 by 480 resolution provides sufficient clarity for text and simple graphics. It allows you to display system data like temperatures or fan speeds clearly. Higher resolutions offer sharper images, but this level is adequate for most visual needs. When evaluating displays, consider how sharp the text appears at a viewing distance. This resolution balances detail with the processing power required to render images smoothly.
Design and Build Details
The listing describes a 360mm black AIO with an all-metal bracket system. This choice suggests higher durability compared to plastic alternatives. The pump head attaches to the screen via magnetic mounting. This design allows for easier installation and removal during setup or maintenance. The unit weighs 5.84 pounds and measures 17.5 inches in length. These dimensions fit standard full-tower cases. You must verify case clearance before purchase. The height is 5.75 inches, which may interfere with large air coolers on the memory slots. The width is 9.37 inches. This width accommodates standard 120mm fans across the radiator. The finish is black, matching the model name. This color choice helps the unit blend into dark-themed builds. The screen bezel is ultra-narrow. This design maximizes the visible display area. The 3.5-inch IPS LCD shows 640x480 resolution. This resolution supports custom themes and media files. The listing notes that the software requires a USB 2.0 connection. You need an available header on your motherboard. The metal brackets cover Intel LGA 115X, 1200, 1700, 1851 and AMD AM4, AM5 sockets. This broad compatibility simplifies installation for most modern platforms. The floating ARGB ring surrounds the pump. This lighting complements the screen display. You can adjust the lighting to match your theme. The magnetic connection ensures the screen stays aligned with the pump head. This reduces the risk of misalignment during transport or case movement. The all-metal construction implies a solid feel. It does not feel lightweight or flimsy. This build quality suits users who prioritize longevity and stability in their cooling solution.
Setup And Daily Use Guide
Installation begins with mounting the all-metal brackets to your motherboard. The listing confirms support for Intel LGA 115X, 1200, 1700, and 1851 sockets, as well as AMD AM4 and AM5. The magnetic connection between the pump head and the screen simplifies the final assembly step. You attach the screen to the pump without complex wiring for that specific segment.
For daily operation, you must download the Ocypus Display software from the official website. This application is required to customize the 3.5-inch IPS LCD screen. The software supports Windows 10 and Windows 11. It connects via a USB 2.0 port on your motherboard. You will need to add the software to your system security whitelist. Without this step, the program will be blocked by your operating system.
Once configured, you can display MP4 videos, JPEGs, BMPs, PNGs, and animated GIFs. The screen resolution is 640 by 480 pixels. The ARGB lighting encircles the pump head. You can set the lighting to complement the screen content. The fans use fluid dynamic bearings. A speed reduction cable is included. You can install this cable to lower noise levels. Without it, the fans run at full speed. This allows you to balance acoustic performance against thermal capacity. The system supports a thermal design power of up to 310 watts. This setup ensures the cooler integrates cleanly into modern high-performance builds.
Before You Buy This AIO
You need to ensure your case has enough clearance for this 360mm radiator. The listing notes a width of 9.37 inches and a height of 5.75 inches. Verify your motherboard socket matches the supported list, which includes LGA 1700, 1851, and AM5. You must download the Ocypus Display software from the official site. It requires a USB 2.0 port on your motherboard. Add the software to your system whitelist to prevent security blocks. Daily upkeep involves keeping the radiator fins clear of dust. This unit sits alongside other high-capacity AIOs in the 1 options reviewed here. It suits users who want custom visual themes via the 3.5-inch screen. If you prefer silent operation, note the fans use FDB bearings. You can adjust speeds with the included cable. Check your CPU TDP against the 310W rating. This cooler targets high-performance builds where thermal headroom matters.
