Thermal Grizzly's WireView PRO II will shut down your PC to prevent GPU cables melting

Last year, we got our first look at Thermal Grizzly's WireView Pro tool for GPUs using the 12VHPWR and 12V-2x6 power connectors. A device for high-end GeForce RTX graphics cards, this tool offers valuable data by measuring and monitoring temperature and power directly at the connection point.

Fast-forward to Computex 2025, and we've seen more cases of melting cables for the 575W GeForce RTX 5090 emerge. Investigations, like this one from De8auer, have discovered a potential imbalance in the GPU's power getting evenly spread across all of the individual cables found on the newer 12V-2x6 power connector.

With that, Thermal Grizzly was back at Computex with a prototype of the new WireView Pro II, which has been designed to monitor and detect issues related to the new power connector. And yes, this includes the ability to measure per-pin current to detect imbalance loading and warn users in advance of any potential failure due to power issues.

The new WireView Pro II is larger than the original, with a bigger LCD that can display more data and an active cooling solution (which is, in effect, a tiny fan) to ensure airflow around all of the connectors and prevent the WireView Pro II from overheating. Being able to measure the current being pulled by each pin on a 16-pin connection on a card like the GeForce RTX 5090 makes this the sort of device all owners with the latest flagship should consider - if nothing else, to ensure that their costly investment doesn't die due to a power balance issue.

Thermal Grizzly has added a security feature to the device. Connecting it to your PC's power via a splitter cable can automatically shut down your PC if a significant issue is detected. The company notes that it would effectively prevent power cables from heating up and melting once that kicks in.

The WireView Pro II sounds fantastic as a pure power monitoring tool, too. It provides more detailed logs for benchmarking or tracking the power usage of your GPU, with data going back months. The version we saw at Computex was a prototype, with the company planning to launch the WireView Pro II sometime later this year.
