I was just wondering if it was preferable to plug a case fan into a normal 12v plug, or onto a fan plug on a motherboard, since I thought I heard once that can be dangerous, if it shorted, it could damage the motherboard. Any truth to that?

Yes, plug it into the PSU and not the mobo if it is a case fan and has a molex connector. Ive read that a fan is a fan is a fan. But just to be safe.

:withstupi good advice! Plugging fans into PSU (even getting adapters if necessary) takes stress off the mobo...which is always good.

The only real advantage is being able to monitor the fan speed, but that can be done with a fan control thingy (I don't know the proper term) you can put it right in your CD Drive bay, some even fit in the floppy.

Definitely plug it into the molex connector on the power supply. A "dead short" on a fan connected to the mobo can destroy the mobo. If you are wanting control over the case fans, take "Ender's" advice and buy a controller for the case fans.

I would only connect the CPU and the Chipset fan, if you have one, to the mobo. Think of it this way, the more things you connect to the mobo the more juice that will be pulled through the mobo, let the mobo use what it needs to supply the AGP, PCI, Ram, CPU, etc. and let the power supply take the punishment. it's alot cheaper to replace the power supply than the mobo.
