the guy at the computer store is confused as to what you have ... you have a 230-volt fan, it's useless to you ... a website named 'coolerguys' sells computer fans, either 12v or 110 volt ... you can buy a powerful (100cfm+) 110-volt computer fan for about $15, some are less than that ... be simpler, and I've run one of those for a couple yes, still like new ... :thumbsup:
