Hi all. Quick question. This has been bugging me for a while so decided to get some expert help from you guys. Lately my new mac mini fan has been operating at full speed sometimes when the computer wakes from sleep and also while restarting or when holding down command and R for the recovery partition. This is getting very annoying! I have reset the SMC as per apples instructions and it has got better. I am wondering if my external firewire drive is causing problems. I will explain my hardware set up. One UPS which is plugged in and the mini runs off that. USB cable from the UPS is attached to the back of the mini. I have one thunderbolt display, one printer on USB, one EYETV USB dongle, Bose speakers plugged into the USB as well. The firewire drive goes to sleep after 30 mins have elapsed. I guess if I am not using it, eject it and leave the cable from the back of the drive unplugged until I need it again? trying to unplug it from the mini is a chore as the desk space is small. Any thoughts would be great. Thanks.
