I just installed a GigaByte GA-MA78GM-S2H mainboard.
The heatsink shown in the picture below is loose. If you touch it with the board vertical it wobbles toward and away from the board. That's a beefy heatsink so I assume handles a lot of heat and is important -- I think it's the sink for the north bridge. In my experience a heatsink needs to be tight against the part it's cooling. Any comments/suggestions? Should I return the board, contact GigaByte, ignore it . . . what?
PS I couldn't find any forums on the GigaByte website. Don't they have any or did I just miss them?
I found that one of the white plastic spring-loaded pins (see picture) which hold the heatsink down had not been seated (pushed through the board). It took a little force but once I pushed it through the heatsink no longer wobbled/tipped away from the board of it's own weight. I could pull it away but it didn't fall away. If the pin moves up and down while the heatsink is pressed against the board the pin is seated -- if not, it probably isn't.
I kept the board. I checked the processor temperature regularly for the first few hours of operation, then less and less frequently. I still check it occasionally. It runs a little warm and I'd worry about this if I overclocked but I don't.
