Thermal Grizzly and Noctua Launch WireView Pro II Noctua Edition at $219.90

Thermal Grizzly and Noctua have officially launched the WireView Pro II Noctua Edition, a redesigned version of the GPU power monitoring device built specifically for modern graphics cards using the 12V 2x6 connector. Originally shown as a prototype at Computex 2026 and teased again in late September, the finished model is now available with a suggested retail price of $219.90 in the United States and €189.90 in Europe. The collaboration keeps the monitoring and protection features of the existing WireView Pro II while replacing its cooling system with a larger Noctua fan, an enlarged aluminum heatsink, and a revised enclosure designed to remain passive for longer under load.

The WireView Pro II sits between the graphics card and its power cable, measuring current individually across every 12 V conductor rather than relying only on total GPU power. That allows the device to identify uneven current distribution that could indicate poor contact or developing resistance at part of the connector. It also monitors voltage, temperature, and total power consumption through its integrated TFT IPS display. User defined thresholds can trigger visual and audible warnings, while the included splitter cable can be configured to shut down the system automatically if selected limits are exceeded. Measurement data can also be recorded for later analysis.

The Noctua Edition does not change that monitoring architecture. Its main upgrade is cooling. Thermal Grizzly replaced the standard model’s 30 mm fan arrangement with a Noctua NF A4x10 PWM fan, an enlarged CNC machined aluminum housing, an additional cooling plate, a thermal pad, and a custom fan grille. The fan operates semi passively, remaining off until temperature and power conditions require active cooling. The display also receives a Noctua themed interface, while Normal and Reversed connector versions remain available for different graphics card layouts and cable routing.

Noctua’s own testing shows where the redesign makes the largest difference. With all case fans disabled and internal case temperatures above 40°C, the Noctua Edition kept its fan switched off at GPU loads of 200 W, 250 W, and 300 W. The standard WireView Pro II activated its fan after 5 minutes and 40 seconds at 200 W and after 2 minutes and 15 seconds at 300 W. At 400 W and 480 W, both devices eventually required active cooling, but the Noctua model remained passive for substantially longer and kept the monitored GPU connector around 3°C cooler on average. These are Noctua’s internal test results rather than independent measurements.

Once active, the acoustic difference was also substantial in Noctua’s test environment. The standard model operated at around 5,000 RPM and measured 39.4 dB(A) from 10 cm, while the NF A4x10n stayed below 2,000 RPM and measured approximately 21.5 dB(A) at the same distance. Noctua calculates those readings as approximately 19.4 dB(A) and 1.5 dB(A) respectively at 1 meter. The company itself notes that even the standard WireView Pro II is already quiet, so the new edition is primarily aimed at systems optimized for extremely low noise.

The launch is particularly relevant as high power 12V 2x6 graphics cards continue generating concern around localized connector heating. We recently covered a PNY RTX 5090 connector failure where severe damage developed around individual contacts despite the card reportedly being underclocked. Products such as the WireView Pro II attempt to catch that kind of problem earlier by looking at each conductor separately rather than assuming normal total board power means every contact is sharing current evenly.

Thermal Grizzly also continues to provide a 2 year extended warranty covering damage to a graphics card’s 12VHPWR or 12V 2x6 connector when the applicable warranty conditions are met. Buyers are advised to check the company’s compatibility list and technical drawings before purchasing because GPU connector orientation, cooler dimensions, case clearance, and cable direction determine whether the Normal or Reversed version is appropriate.

The Noctua Edition is not a new generation of WireView monitoring technology. The electrical monitoring, alarms, shutdown functionality, and per conductor measurements remain fundamentally the same as the standard Pro II. What Noctua changes is how much additional heat and noise the monitoring hardware itself introduces into an enthusiast system.

That may sound like a niche problem, but the target audience is equally specific. Someone already spending heavily on an RTX 5090 class GPU, premium cooling, and a near silent PC may want individual connector monitoring without adding another small fan that becomes audible at low system noise levels. The $219.90 price makes this a premium safeguard rather than an essential accessory, but the combination of per conductor monitoring and automatic shutdown addresses a real weakness in relying on total GPU power alone.

Would you spend $219.90 on active 12V 2x6 monitoring for a flagship GPU, or should this level of protection already be built directly into the graphics card?
