Ocypus Sigma L36 ARGB 360mm with 2.4″ IPS Display AIO Liquid Cooler – Black | White

Ocypus Sigma L36 ARGB

The Sigma L36 ARGB is a high-performance all-in-one liquid CPU cooler that delivers efficient thermal management, dual-purpose aesthetics and broad system compatibility — making it a solid choice for gaming rigs, content-creation workstations, and performance-oriented builds.

Premium Cooling with Cutting-Edge Pump Design

At the heart of the Sigma L36 is a robust pump assembly built around a ceramic-bearing shaft and a finely-engineered microchannel architecture. The pump operates at up to 3100 RPM ±10%, yet keeps noise under 27 dB(A). Its design ensures stable, long-term operation even under heavy loads, while ceramic bearings offer enhanced durability and reliability.

The cooler includes a large radiator (397 × 120 × 27 mm, aluminum) and three high-performance 120 mm fans that combine to deliver strong airflow and pressure. Each fan operates between 500–2000 RPM (±10%), providing up to 73 CFM airflow and 4.3 mmH₂O static pressure, while keeping noise levels ≤ 29 dB — a balance of cooling power and quiet operation ideal for both gaming and productivity workloads.

Efficient Heat Dissipation & Compatibility

Liquid coolant travels through 400 mm tubing (outer diameter 12.5 mm, inner 6.5 mm), connected between the radiator and the pump block. A precisely-engineered copper baseplate inside the pump block, paired with the microchannel structure, maximizes heat transfer from the CPU to the coolant, allowing the Sigma L36 ARGB to handle high TDPs and keep multi-core CPUs running cool even under sustained load.

The cooler supports a wide variety of CPU sockets — including modern Intel (LGA 115X / 1200 / 1700 / 1851) and AMD (AM4 / AM5) platforms — ensuring compatibility with most current-generation desktop builds.

Style Meets Function — ARGB Lighting & Aesthetic Design

Beyond performance, the Sigma L36 ARGB stands out with its integrated ARGB lighting and sleek visual design. Its pump head features a refined, floating-style design and a ring of diffused light that casts soft, layered illumination — ideal for builders who want both performance and visual flair. The lighting can be synced with other ARGB components for a cohesive build aesthetic.

Balanced Performance — Quiet, Reliable, and Versatile

Between the efficient liquid-cooling radiator, a powerful but quiet pump, and silent yet effective fans, the Sigma L36 ARGB strikes a compelling balance between thermal performance and acoustic comfort. It’s well-suited for heavy workloads — gaming, rendering, video editing, or multitasking — while staying quiet enough for daily use or home office environments.

The unit’s relatively compact and versatile layout makes installation straightforward in most mid-tower or full-tower cases, and its all-metal mounting hardware ensures secure fitting across supported CPU platforms.

Ideal Use Cases

• High-performance gaming rigs with multi-core CPUs
• Content-creation workstation builds (rendering, video editing, 3D work)
• Silent or low-noise builds where acoustics matter
• Systems with ARGB lighting or showcase windowed cases
• Upgradable rigs where future CPU/platform flexibility is desired
