Ocypus Sigma L24 ARGB 240mm vloeistof-CPU-koeler - zwart

High-performance CPUs demand cooling that keeps pace without turning your PC into a wind tunnel. The Ocypus Sigma L24 ARGB addresses that with a 240 mm all-in-one liquid cooler engineered for efficient heat dissipation and quiet operation. Its dual 120 mm PWM ARGB fans and copper cold plate pull heat away from the processor, while the aluminium radiator dissipates it quickly. The result is stable performance under load, with fan speeds from 800 to 1800 RPM and noise levels between 18 and 32 dBA.

Who is it for

This cooler suits system builders and gamers who want reliable liquid cooling in a compact 240 mm form factor. It fits cases with space for a dual-fan radiator and supports a wide range of Intel and AMD sockets, including LGA 1700, AM5, and AM4. The ARGB lighting on the fans and pump adds a customisable glow that syncs with 3-pin 5V ARGB headers.

Tips

Check your case clearance for a 240 mm radiator before purchase. Connect the ARGB cable to a compatible 3-pin 5V header on your motherboard or controller to control lighting effects. The PWM fans can be tuned via BIOS or software for a balance of cooling and noise.
