Hi,
ECS Mobo, NVidia chipsets, AMD CPU's, Gigabyte forum
In the interests of fair play and, having checked out the other forums I think I can see why you came here to get an answer.
Having spent a little time browsing the web it turns out that these chips do run hot..... in fact they can get very hot and the temps you are showing are about average. The fact the one is running hotter than the other also shouldn't worry you as the different components in each of your rigs will run at different specs.
If your systems are stable then you really don't need to worry.
hope this helps
