Can I join? My old 790x UD4P died recently and I went with a 970a UD3 as a replacement.
Seems like the best non-SLI/Crossfire board out there right now for AM3+.
After reading the posts about the NB temp concerns, and upon close visual inspection, I decided to swap out the NB heatsink on the 970a for the NB/VRM heatsink on my old 790x.
The fit was about perfect. The only issue I ran into was the NB heatsink pins on the 970a are much wider then the pin holes in the 790x NB heatsink, they would not fit.
The mounting holes for the NB heatsink on the 970a motherboard are also extra wide to accommodate those wider new pins, so the old 790x NB heatsink pins wouldn't fit.
Ended up using some very small nylon nuts to secure the 790x heatsink on to the 970a board with the smaller pins (basically washer mod with nuts).
Since the holes on the board were so big, using the tiny nylon washers there was alot of flex.
The VRM heatsink portion mounted with the original pins. I liked the thermal pad Gigabyte put on the stock 970a VRM heatsink so I reused it.
I'll try some of the Fujipoly I have leftover if I end up not happy with the temps. Used Pro PK1 on the NB.
Can't report temps now because my memory hasn't arrived yet. Still got a couple of days to tinker around with something until then.
One of these days I'll get a better camera.
