"For some reason the fans just started going full-tilt all the time"
Sounds like a kernel panic to me. My brand-new iMac did that on its first day right out of the box ... nothing on it but system software. First, and only, time - go figure.

The Mac fans are (apparently) under software control, and a number of testing routines also rev up the fans. It can be unnerving when you first hear it.
- kaffeinecoma 17y agoNo, a Kernel Panic would result in a crash. All modern computer fans are under software (BIOS/firmware) control. I also tried re-installing the OS to no good effect. The machine was totally functional, except for the fact that it was miserable to be in the same room with because of the noise.
