Hello,

Almost every time I do activate the serial port on the Mac (MacBook Pro 2011 - i7 quad core 2.33 GHz) to get a serial stream from an Arduino, the fan starts to run quite heavily, even with low datarates such as 9600 kbps or 19200 kbps. I do not understand why it does so as, for instance, several USB controllers are connected to the computer too and they don't trigger the fan in any comparable way.

So does the Mac have a conservative way to handle serial connections ? Too conservative ?

I thought about using a utility (such as Macs Fan control or smcFan Control) to control the fan speed, but how should I set it according to the serial throughput to avoid problems but reduce the noise as much as possible ?

Thank you in advance.
