The Sigma L36 BK ARGB adds ARGB lighting. These models require more case space. Choose them if you prioritize display customization and raw cooling power over compact dimensions.
Where Ocypus Fits Your Build
Ocypus covers a clear size range from 240mm to 360mm radiators. You get options for compact cases or high-TDP processors. The lineup includes digital displays and larger LCD screens. ARGB lighting is available on the 360mm model. All units use USB-connected displays for customization. You will not find 120mm single-fan coolers in this list. There are also no non-display models here. Every option includes some form of screen. This range suits users who want visual feedback and solid thermal headroom without needing smaller form-factor solutions.
Choosing the Right Ocypus AIO
-
Check Case Compatibility
You must verify your case supports the radiator size you choose. The Iota L24 measures 15.2 inches in length, fitting most mid-towers. The Sigma L36 models are longer, reaching up to 17.5 inches for the PRO version. Ensure your case has enough clearance for the block height and fan thickness. Compact builds benefit from the 240mm Iota, while larger cases accommodate the 360mm options. Measure your available space before purchasing to avoid fitment issues during assembly.
-
Select Display Type
Ocypus offers two distinct display technologies. The Iota L24 features a simple digital display showing temperature data. The Sigma PRO L36 includes a larger 3.5-inch LCD screen for detailed visuals. The Sigma L36 ARGB also uses an LCD but adds magnetic assembly. Consider whether you need basic temperature monitoring or advanced customization. The LCD screens require USB connection for configuration. Digital displays provide straightforward functionality without complex software setup.
-
Match Cooling Capacity
Radiator size directly impacts thermal performance. The 240mm Iota suits mainstream processors and compact builds. The 360mm Sigma models handle high-TDP CPUs more effectively. Larger radiators dissipate heat faster due to increased surface area. If you run intensive workloads, the 360mm options provide better thermal headroom. The Sigma PRO L36 supports high thermal capacity demands. Choose the size that aligns with your processor's power requirements and case constraints.
-
Consider Lighting Needs
Lighting options vary across the lineup. The Sigma L36 ARGB model includes addressable RGB fans for customizable effects. The Iota L24 and Sigma PRO focus on cooling and display features. If aesthetic synchronization is important, the ARGB option integrates with motherboard software. The other models prioritize functionality over lighting. Decide if visual customization is a priority for your build. The ARGB fans allow for color and pattern adjustments via software control.
-
Evaluate Setup Complexity
Installation difficulty depends on the model features. The Sigma L36 ARGB uses magnetic assembly for easier fan attachment. The Sigma PRO L36 requires USB configuration for its large LCD screen. The Iota L24 offers a simpler digital display setup. Consider your comfort level with software configuration. USB-connected displays need specific cable routing inside the case. Magnetic mounts can simplify assembly for beginners. Review the installation requirements for your chosen model before starting your build.
