Thanks for the pre-emptive warning! I could've used that about the bios...
Anyway, yeah I've already noticed how hot the VRM's are. I've already got a fan blowing on the back of the first card. Not any of the others cause they already have air moving behind them from the card behind them. The first card doesn't have that, hence the added fan. I'll probably stick on some heatsinks on the back of each of them. Something like this:

I'm thinking I can pick up a box of old cpu heatsinks, like socket 7 old, for a couple bucks. I can hacksaw each of them down the middle, and fit one or two just like in that picture. That should do the trick.
Lol! Where did you find that pic? You sure it wasn't
here?
That's a pic of my 7970. The heatsinks made a little difference, but undervolting them will be where your really big temp gains are going to be. Mine usually sit in the high 90 - low 100s at stock, and high 70 - low 80s when undervolted.
