First don't you mean vac not vdc.DO NOT BUY THE CURRENT REPLACEMENT! It is junk. Measure the fan and get the specs off it. I think it's a 60 or 80mm model at 12vdc. Replacement fan is availble at a computer retailer like Micro Center in Cambridge or online at newegg dot com. You want high cfm (cubic feet per minute), low decibal noise and ball bearing (not bushing). Check the specs. I'd use a Vantec http://www.newegg.com/Product/Product.aspx?Item=N82E16811999602
