      Wow, I really need to undervolt my cards.
      It’s been hitting 35C to 40C in the afternoon.
      My cards are recording temperatures of 84C even with GPU Fan set to 100% and a standing fan hitting them at full blast.

        Sounds like the painful week I just had in Melbourne… I fried a PSU as well :-[ Just gave up in the heat…

          Undervolted my cards to 1.081 but hashrates at 730khash/sec :'(
          Good temperatures though. 73C, looks promising.

          EDIT: Made a few changes. Now mining at steady 755khash/sec at 1075MHz core clock and 1500MHz memory clock. Same 1.081v

              Anyone know of a windows program to regulate the voltage?
              Starting to think my sapphire 280x toxic are voltage locked:(

              My asus matrix cards had no issue with the asus gpu tweak utility (windows).
              But was limited how low i could set em.

                  Mining on MSI R9 280X GAMING cards.
                  Hovers around 730khash/sec when I’m actively browsing the net while mining.
