NZXT Cam

NZXT Cam does two jobs, and it does the first on any computer. Install it and it monitors the machine, with live graphs of processor and graphics card load, clock speeds and temperatures, memory use and network bandwidth, gathered on one dashboard. No NZXT parts are needed for that, and no account.

Add compatible NZXT hardware, a Kraken liquid cooler, a control hub, RGB fans or lighting strips, and a second set of controls appears for fan curves and pump speed, for lighting, and for the screen on top of the cooler.

That split is the honest way to judge it. As a general monitor it is clean and readable and competes with the standalone tools. As the control panel for NZXT hardware it is close to essential, since several NZXT products fall back to fixed defaults or cannot be configured at all without it. NZXT Cam sends anonymised usage and performance data when online, which privacy-minded users should know before installing.

Monitoring on any machine

The NZXT Cam dashboard shows the main readings at a glance, and each opens into a history graph. Processor and graphics card each get load, clock speed and temperature, memory shows usage, and the network panel tracks bandwidth. For a quick answer to whether a game is limited by the processor or the graphics card, or whether a laptop is overheating, the graphs are faster than reading numbers in a sensor list.

Mini mode docks a compact overlay to the desktop so key figures stay visible while you work or play, and an in-game overlay can show frame rate and temperatures on top of a running game. It covers fewer sensors than a full hardware monitor, which lists every voltage and fan reading the board exposes, but it presents the important ones far more clearly.

Fan curves and pump control on NZXT hardware

With an NZXT cooler or control hub connected, the cooling page lists every fan and the pump, each set to a preset, Silent, Performance or Fixed, or to a custom curve drawn as points on a graph of temperature against speed. Custom curves can follow the processor, the graphics card or the liquid temperature reported by the cooler, so a radiator’s fans can respond to the coolant rather than to every brief processor spike.

This is where the software becomes necessary. A Kraken cooler from the screen-equipped ranges runs without it, but only in a default mode with fixed pump and fan speeds, the screen showing liquid temperature and RGB lighting set to plain white.

Some NZXT cases ship with a control hub that will not do anything useful until NZXT Cam is managing it. For fan control across a mix of brands rather than NZXT gear alone, a dedicated fan control program drives the motherboard’s own headers more completely.

Lighting effects and schedules

The NZXT Cam lighting page sets colours and effects for every NZXT RGB device, fans, strips, the cooler’s pump ring and the case, with effects that run in sync or independently. Audio-reactive modes pulse with whatever is playing, and lighting can change on a schedule by time of day, cool white for working hours and a softer colour in the evening.

Lighting control stops at NZXT hardware, so a motherboard’s own lighting or another maker’s fans need their own software. Running two lighting programs against the same device causes flicker and lost settings, so assigning each device to one program is the rule. For a build mixing brands, a cross-brand RGB controller can unify more of it, with this tool kept for the parts only it can reach.

The Kraken screen

The circular screen on the screen-equipped Kraken coolers is configured here, and it is the feature that sells the hardware. It can show live readings, the processor or graphics card temperature, load or liquid temperature, styled as dials or numbers, or it can show an image or an animated GIF of your choosing. Web integrations put live content from supported sources on the screen as well.

Without the software, the screen falls back to liquid temperature, so anyone who bought the cooler for its display needs this running. Images and GIFs upload directly, and the screen keeps showing them while the program runs in the background.

Resource use and the background question

Software that watches the machine constantly, as NZXT Cam does, uses some resources. Users periodically report the program using several percent of processor time while idle, particularly with the overlay switched on, and turning off the overlay or lowering the monitoring refresh rate usually brings that down. It starts with the system by default and runs in the tray, which is necessary for the hardware control to keep working.

Because NZXT devices depend on it, uninstalling is not a neutral choice on a machine with those parts, since the hardware drops back to defaults. On a machine with no NZXT hardware, it is purely a monitor, and anyone who finds the background load annoying loses nothing by removing it.

When removing it, an uninstaller that sweeps leftovers clears the services and settings the standard removal can leave behind.

Conclusion

NZXT Cam suits owners of NZXT coolers and hubs, or its lighting, for whom it is the only way to set fan curves, choose lighting and use the Kraken screen, and it suits anyone else who wants a tidy monitoring dashboard without creating an account. The cooling graph editor and the Kraken display tools are both well made.

On a machine without NZXT parts it is a pleasant monitor that you can take or leave, and its background load and data collection deserve some thought. Keep the overlay off unless you use it, give each lighting device to a single program, and it runs the NZXT side of a build the way the hardware intended.
