Folks,
You can solder an LED wherever you like, but how is it going to know when
the fan stops? Don't jump, relax. Now tell me.
Motherboard are available with teperature sensors, implemented on-board.
The Linux kernel can read this, with calls to /dev/temperature, (after the
proper mknod) and initiate a shutdown.
These motherboards are expensive, because they typically tend to be
high-end, SMP, remotely bootable.
Now the original question. Ajit, I assume your desire to not open the box
is to preserve uptime? One, if your CPU fan was dead, you would know, in
10mins or so. Two, if you have unused HDD slots, pop open the decals on the
front cover, they should help cool the box.
