Hello friend, can you check the specification of the fan, is it DC or AC? 12V DC is the standard for ATX fans. Ahh, you're trying to plug in a fan without using an AT/ATX 12V DC PSU. Ahh no need, grab yourself a pc PSU and connect a switch up to the ATX SOFT_ON (green) and BLACK GROUND (black) it's pins 13 and 14 I think. It shouldn't be dangerous as the switch is low voltage..

Hmm well, there are other ways that might be more practical than buying a convertor if you have a spare AT/ATX psu around. :-)

If the fan is prefabbed with molex connector, AT/ATX is a good idea, I'll grab some pictures later of my psu for my fan ;-)

Peace,
