the airport extreme card in my intel iMac is generating much heat: 63-67°C
1. Is there any solution to decrease the output power to reduce the heat generation?
2. change the radio frequency to 5GHz?
because in this case -I think- less output power is enough for airport communication.
I think there is no express card power management utility maybe direct terminal commands can solve the problem regarding that the aluminum housing affects the signal broadcast

huh, ok.

How are you sure this is too much heat? I would think that Apple would have set this to the right settings.

the 3 cooling fans are working permanently also displayed by the widget+I've reduced the radio output power on my airport express base station to 10% and it is generating less heat than earlier with full power

just curious, perhaps it's something else causing the fans to run continuously? Like this iStatPro widget you got?

Or some other program?

How old is the iMac?

I just downloaded and installed that widget and don't see where it records the Airport card temperature. It reports the CPU and HD temps as well as the backside and drivebay temps. Where is the Airport card temp reported??

perhaps the ambient temp is higher than optimal, but if it is the situation summer heat would be a potential danger for my Mac.
very useful widget.

Where are you located?

I'm not saying the widget is not useful, but I'm wondering what else could possibly causing the fans to run fulltime. Sometimes software can do that to the fans.

Can you take it to an Apple store?
