Thermal Grizzly and Noctua have launched the WireView Pro II Noctua Edition, an inline power monitor for high-end graphics cards. Available now for $189.90 or €189.90, it pairs the WireView’s connector monitoring and alerts with a redesigned heatsink and a quieter Noctua fan. The companies say the update targets noise complaints without changing the monitor’s core features.
Key takeaways
- The device monitors current on each 12V conductor, along with power, voltage and temperature.
- A 40mm Noctua NF-A4x10n fan replaces the standard model’s 30mm fan.
- It supports configurable alerts and optional automatic system shutdown.
- Launch pricing is $189.90 / €189.90, with two years of connector coverage from Thermal Grizzly.
A quieter cooling design
The Noctua Edition keeps the WireView Pro II’s monitoring hardware but redesigns its cooling around a CNC-milled aluminum heatsink, cooling plate and thermal pad. Its frameless NF-A4x10n fan runs semi-passively, remaining off until cooling is needed. The housing and fan grille have also been adapted for the larger rotor.
In testing described by the companies, the fan stayed off at GPU loads up to 300W under high ambient temperatures. At 400W and 480W, it reportedly took more than twice as long to start as the standard model, while keeping the connector about 3°C cooler. When running, the Noctua fan operated below 2,000 RPM and measured 21.5 dB(A) at 10cm, compared with 39.4 dB(A) for the standard model in the same test.
Monitoring and protection features
The WireView Pro II sits between a compatible GPU and its power cable, measuring current individually across the 12V conductors rather than reporting only a total. That can help reveal uneven load distribution or potential contact problems that may lead to localized heating. The integrated TFT-IPS display shows monitoring data, while configurable thresholds can trigger visual and audible warnings.
Using the supplied splitter cable, the unit can also initiate an optional system shutdown when a configured limit is exceeded. USB-C firmware updates and optional PC software are supported. The device is designed for graphics cards with 12VHPWR or 12V-2×6 connectors, including current high-end GPUs such as Nvidia’s RTX 5090. It can provide an early warning, but it cannot correct a poorly seated plug, damaged cable or faulty contact; careful installation remains essential.
Price and availability
Thermal Grizzly lists the Noctua Edition at $189.90 in the US and €189.90 in Europe, and says it is available through its online store and sales partners. The companies also include two years of coverage for the graphics card’s 12VHPWR or 12V-2×6 connector under defined conditions.
The price positions it above the standard WireView Pro II, making the upgrade most relevant to builders prioritizing lower noise and additional cooling for a high-value GPU. For buyers whose main concern is simply monitoring a connector, the premium is for the revised cooling design—not a different set of core monitoring features.
