Update for those interested:
I was able to set fan speed manually on all four cards by attaching a monitor to each one, restarting X (gdm3), saving the new xorg.conf and then restarting X again. What a pain!
After spinning up the fans to make sure I wouldn't cook anything, I tested +250MHz on the cards. Performance was initially good, but it wasn't stable. I dropped to +200MHz and tested again. This time the cards were stable and I was able to do additional benchmarking. Multi-hash is still slower than I expected, but single hash is very close to the other benchmarks I've seen: hovering around 19500MH/s.
Thank you again epixoip for your commentary and advice. I'm learning a great deal from you and the other experts on the forums and, for that, I'm very grateful. Thank you.
