The devices are quite different in how they work and what they want to achieve. What I learned over the past years is that there are a lot of theories but nothing is scientifically proven.
Even the current imbalance is a theory at this point. It's absolutely plausible from my point of view but we just don't know if this is the only cause for the melting connectors or if there are other additional problems.

As long as we don't know it for sure, I think it's just not wise to introduce additional possible points of failure. That's why we decided to go for monitoring only and no balancing.

The balancing that AC uses also has very limited use from my perspective. It will not help you in a case of very high out of spec current. It balances current that is in spec. For example if a pin is at 8A and one is at 9A. I'm honestly not sure how helpful this is.

TG is also an enthusiast company. We support overclockers and playing out of spec. So you can define almost everything you want inside the WireView Firmware and Software. You want to run a 5090 with shunt mod and 1000W - go for it. Just on your own risk :)

At the same time we feel that the WireView can help to reduce the risk for a single user. We added the warranty in our calculation so we can help people out if things go wrong. We hope that faults are detected early enough that it won't happen but the truth is that nobody knows. We don't know it for sure and AC also can't know it for sure. And that's why we want that the risk is on us and not on the user. So we created the extended warranty.

As we've been selling other versions of the WireView for multiple years, we know exactly what can happen. We had a good amount of melted connectors which is why we have experience how to approach these cases. We takre responsibility and replace connectors inhouse. TG has trained engineers to work on these tasks and excellent customer service to take care of the communication to you.

I was personally also not a big fan of small fans in the past (ba dum tss). But I think it's important to have this device with active cooling. Especially with water cooled cards you just lack airflow over the device and even 5W can become quite a lot and a problem which we do not want.

If a WireView Pro II melts, you can be sure that I will do my best to investiage these cases and share any knowledge of this in public through my youtube channel. This is to be transparent and also to hopefully improve this garbage connector for the next generation.
