Not all the failures have been under extreme cooling conditions. Read the threads at xtremesystems again and you will see that there are a number of boards with the same damage that were not run at extreme conditions.
My motherboard has the Foxconn socket. I have it running at stock. But why should I have a dodge socket that can potentially damage my CPU some time in the future, especially if Gigabyte have changed socket supplier. Those overclocked systems simply bring to the fore the problem sooner. The problem is still their regardless if you over-clock or not. At the end of the day we have a 1156 socket that does not make contact with all the pads on the CPU. That means those pins that are making contact have to work harder even under stock conditions. I see it as a concern for the long term.
I personally think that Gigabyte should offer a swap out for those of us who do worry about a sub standard socket. If others are happy with their motherboards then they do not need to swap them out. A full recall might be over the top, but possibly appropriate.
I am very happy with the Gigabyte brand, this is not their mess up. My next board will most certainly be another Gigabyte but lets not do the head in the sand thing here. We have a potential problem that could in time kill or permanently damage both the motherboard and the CPU. Prevention is always better than cure I believe.
