mid 2012 rMBP: normal idle temperature?

    I have a mid 2012 rMBP, 2.3GHz i7, 8GB, 650M GPU. iStat Menus reports the following temps:

    CPU Cores 1-4: 75 to 80C
    CPU Proximity: 61C
    GPU Die - Analog: 66C
    GPU Proximity: 62C
    Fans: 2,700 (left), 2,500 (right)
    System 98% idle

    This is in clamshell mode, driving an external monitor. I'm assuming the core temperature is the relevant measurement (not CPU proximity)? If so, does this seem abnormally high for an idling system?

    The CPU temps are a bit high for an idle system, so it's very likely it's not idle. Check Activity Monitor to see what processes are consuming resources.

    Thanks for replying. Activity Monitor shows processes consuming no more than 2-4% CPU at any given moment (WindowServer, kernel_task, etc.). As far as I can tell, there are no processes consuming significant resources.

    Get an air duster and blow out the dust. Push air through the side vent holes. Being a mid 12 there will be some dust bunnies in there by now.

    Good suggestion. I'll try that tomorrow and see if it helps.
