Is there any danger to powering a 12V 200mA case fan via USB at 5V 500mA max?
If wired correctly, this will not damage the fan or the USB port, as the fan will take less current at a lower voltage. The main problem with this arrangement is the fan would either not start, or would run very slowly, so probably useless for cooling anything. If you can get a 5V fan, not more than 500mA, this would be much more effective. (Note- If wired incorrectly, reverse polarity could damage both USB port and fan, short circuit could damage your USB port.)
