As does the bridge IC on my ATI provided Radeon X1300 AGP card. It too has a
pad on the IC. I'm not sure of the pad's function--it can't really be
helping the IC shed heat.
The card has run reliably 24/7 for a few years now. Some ICs can run hot and
be fine, maybe this is one of them.
I can't see the temperature of the bridge IC changing a lot based on
workload. It's always doing about the same thing--forwarding and translating
information between GPU and system.
Then again, I've seen more AGP and PCI Express video card failures from heat
than anything else. I still have PCI, ISA and even Microchannel video
adapters that just keep right on working and don't heat up as though they
were using power sufficient to run a small town. Since I don't get into
gaming, the performance of these old adapters is in many cases more than
sufficient.
