Without a monitor connected (via Thunderbolt/mDP) to my iMac (2011, 3.4 GHz, 6970M 2GB), iStat Menus reports the GPU is using ~15 watts, and has a temperature of 60c. With one connected, it uses ~35 watts, and is ~80c. Both of these are when idling.
Regardless of it pushing an extra 1920x1200 monitor, 80c seems very excessive. I use my computer near enough everyday for up to 10 hours, and I'm worried about the long-term stress due to such a high temperature. Running Battlefield 3 for hours on end doesn't exceed ~65c!
Is this normal behaviour for displays via the Thunderbolt port, and if so, is it safe long-term?
(SMC reset, fans working correctly, no dust in air ducts, etc.)
