I think you are mis-reading the specs of the fans. No PC PSU has a fan that draws 12 amps. Are you sure it isn't 0.12 amps?

That said, as long as they're both 12V fans you should be OK as long as you wire the replacement with the correct polarity.

Also, please note that the line side capacitors can store a potentially lethal charge even after the PSU is switched off and unplugged. If you aren't familiar with proper procedures for working on equipment with hazardous voltages, you may want to pass on this mod.

Yeah...if the PSU is old, it might just be easier to buy a replacement. Even if you can safely replace a fan, other componenets are bound to have degraded, and it won't do you much good fixing a fan just to have the PSU fried in the next thunderstorm.
