I need help with modding this AT psu.

I want to use an old AT power supply to just run fans. My router and DSL modem run pretty hot, so I thought I would mod them for fans. The psu won't fit inside either of them, of course, so I figure I can mod the whole works into a case, psu included.

Do I need to load the 5V rail with a resistor, or can I simply use the 12V rail to run the fans without doing anything else?
 
I use one for powering some bench-top multimeters, and only load the 12 V line. But it depends on the power supply. Look on the label - along with the the maximum ratings it may give minimum loads.

If it doesn't say, give it a try with just the fans. Not much loss in blowing up an AT supply.
