Tony, Do not get to close to your refrigerator in fear that it may jump out and choke you. Most refrigerators are designed to transfer temperature in a specific area. You added a long arm of cubic feet to it that it just cannot handle. It is busting it's butt and eventually you will not have to worry about how expensive it will be to run. It will simply shut down. Big question for you - are you returning the air back to the refrigerator once it is routed to the faucet? And why are you using such a large blower?
