    I connected my MBA to a LCD TV via thunderbolt HDMI and i feel that my MAC is getting hotter. the temp is always ~65 C and fan RPM ~5200 even though i dont run any CPU hungry app. normally the temp remains at 50 C/ 2000rpm.
    so does dual monitor cause this? its really annoying with the sound of the fan when its over 4000rpm. guess i need to remove the external monitor?
    thank you

    Two displays = more work for the GPU = more heat. It's perfectly normal for it to be somewhat hotter. There may also be other factors at work.
    1. Launch Activity Monitor
    2. Change "My Processes" at the top to "All Processes"
    3. Click on the CPU column heading once or twice, so the arrow points downward (highest values on top).
    4. Click on the System Memory tab at the bottom.
    5. Take a screen shot of the whole Activity Monitor window, then scroll down to see the rest of the list, take another screen shot
    6. Post your screenshots.
