Everything is at stock, with no adjustments, so that takes care of voltage, and clocks. Since I had an issue with just two cards similar to this the intensity is 20 and 19 for the two 7950s, and 18 for the 7970. Also I am curently using GUIminer-scrypt for mining feathercoins. As for the temperature, since the above values are starting from cold, not all that high. However, when the temperature peaks, around 77- 79 per card when all cards are running at the same time.
