Giveaway: Win an Ocypus Sigma L36 PRO 360mm AIO and Sigma F36 ARGB Fan

We're continuing our TweakTown giveaways, rewarding our registered members and newsletter subscribers with top-tier hardware every week. For our latest giveaway, we've teamed up with Ocypus to give one lucky winner a premium PC cooling bundle combining a 360mm liquid CPU cooler with an integrated 360mm ARGB fan assembly.

There will be one winner in total, and the prize includes an Ocypus Sigma L36 PRO 360mm AIO liquid cooler and an Ocypus Sigma F36 ARGB integrated 360mm fan.

• Ocypus Sigma L36 PRO - a 360mm all-in-one liquid CPU cooler with a 3.5-inch 640 x 480 IPS display, customizable videos, images and GIFs, magnetic pump-head mounting, ARGB lighting, a large copper cold plate, ceramic pump architecture, and high-performance PWM fans
• Ocypus Sigma F36 ARGB - an integrated three-fan 360mm cooling assembly with a unified frame, hidden cabling, floating ARGB fan-hub lighting, a full-perimeter light bar, fluid dynamic bearings, and support for both case and radiator installations

The Ocypus Sigma L36 PRO is built around a 360mm radiator and a distinctive pump housing topped by a large 3.5-inch IPS display. The screen runs at 640 x 480 and uses an ultra-narrow bezel, giving users plenty of room for system monitoring or custom visual content.

Through Ocypus Display software, the screen can show system information including temperatures, loads and frequencies, or be customized with MP4 video, JPEG, BMP and PNG images, and animated GIFs. That makes the pump head a prominent visual component in a showcase build rather than simply another cooling component. The display uses a magnetic mounting system that allows the pump head to be installed and rotated more easily, including switching between portrait and landscape orientations. An ARGB ring around the pump housing can also be customized or synchronized with other compatible lighting hardware.

Underneath the display, Ocypus uses a ceramic pump architecture with a 0.1mm microchannel design and a 3700mm² copper base. The pump operates at 3100 ±10% RPM and is rated at no more than 27 dB(A), with the larger cold plate designed to improve heat transfer across modern CPU heat spreaders. The Sigma L36 PRO also includes three pre-installed 120mm PWM fans using fluid dynamic bearings. They operate between 500 and 2400 ±10% RPM and are rated for up to 90 CFM of airflow and 5.8 mmH2O of static pressure, making them suitable for pushing air through the 360mm radiator under demanding workloads.

Ocypus includes a fan-speed reduction cable for users who would rather prioritize acoustics, reducing the maximum fan speed from 2400 RPM to 2000 RPM. The cooler also uses all-metal mounting brackets and supports mainstream Intel and AMD platforms. The second part of the prize is the Ocypus Sigma F36 ARGB, which combines three 120mm fans into a single 360mm frame. This integrated approach reduces visible cabling and gives the assembly a cleaner appearance than installing three separate fans individually.

Lighting is a major part of the Sigma F36's design. Each fan uses an ARGB ring around its central hub that appears to float independently, while a full-perimeter light bar runs around the outer frame. Together, the two lighting zones create a continuous RGB effect across the entire assembly. Performance is rated at up to 2200 ±10% RPM, 82.5 CFM of airflow, and 3.1 mmH2O of static pressure. Fluid dynamic bearings are used to balance cooling performance, operating noise, and longevity. A bundled speed-control cable can lower the operating range to 500-1900 ±10% RPM when quieter operation is preferred.

The Sigma F36 ARGB can be used either as a case fan assembly or on a compatible radiator, making it useful for builders who want to add a large block of synchronized airflow and lighting elsewhere in their system. Together, the Ocypus Sigma L36 PRO and Sigma F36 ARGB provide a substantial cooling and lighting package for a modern gaming PC. The bundle combines a customizable LCD-equipped 360mm AIO with another integrated three-fan ARGB assembly, giving the winner both high-performance cooling hardware and plenty of options for building a visually striking system.
