Cooler Master MasterPlus+ vs Nexus

Cooler Master MasterPlus+ is free Windows software for supported Cooler Master peripherals and PC components. Its compatibility list includes cooling products, fans, LED controllers, cases, power supplies, keyboards, mice, audio products, and accessories. Examples include MasterLiquid coolers, MasterFan and SickleFlow fans, HAF 700 cases, CK and SK keyboards, and MM series mice. For supported Addressable Gen 2 RGB devices, it controls individual LED colors, effects, and brightness. Cooler Master says GD120 ARGB desk lighting can synchronize with display colors and reproduce monitor visuals in real time. Mobius 140P ARGB RGB customization requires a dedicated controller sold separately. The download is labeled for Windows 10 and Windows 11. Version 1.9.6 notes removal of Motion1 motion control and enhanced D-BOX guidance. Cooler Master is headquartered in Taipei City, Taiwan, and was founded in 1992.

Nexus combines PC hardware monitoring, fan and pump control, and RGB lighting in one free app. It shows live CPU, GPU, memory, network, disk, fan, and temperature readings, with per-game FPS history on Windows. Its GPU-rendered lighting engine offers screen sync, audio sync, and Game Sync. Users can set fan and pump curves from any system temperature sensor or leave selected devices on BIOS or firmware settings. Nexus uses its own device drivers and a bundled OpenRGB build; hardware support depends on the exact model. A phone browser can act as a remote panel, using an encrypted relay outside the home network and switching to a direct connection when possible. The app works locally and offline without an account, while optional anonymous telemetry can be controlled in settings. Nexus runs on 64-bit Windows 10 or 11, Apple Silicon Macs, and x86-64 Linux. It has no builds for Windows on ARM, Intel Macs, or ARM Linux. Companion iOS and Android apps are not yet in the app stores.
