Friend may have overheating issues. After about 5 minutes on Final Fantasy XIV, the GPU temps shoot up to 88c. The CPU temps are fine, so it's definitely just a GPU issue.
We've been researching like crazy, trying to figure this out. Is it possible that FFXIV is just really intense for a GT630 and causes it to run that hot? The PC has been dusted, so that's not an issue, and yeah like I said, the CPU runs quite cool.
