I have a Mac Mini 1.1 on which I updated the EFI firmware to v2.1 and installed Mac OS X 10.7
I'm wondering how I can cool the Mac with an external fan somehow. I found the internal cooling to be slow, so I put an external handmade USB fan on the system in an open case and this works well for my purpose.
The problem with the external fan is that when I put the computer to sleep, the fan keeps on working and I don't know how to make it stop.
I don't want to use the system fan as it looks very weak and makes a lot of noise at 3000 rpm. I don't like noise.
