Anyone else have a similar issue? I look in iStat pro and only one fan is spinning! I've filed for a ticket, but after spending 2300 bucks on a computer I'm not overly happy. I tried an SMC reset and that but until I can bring the computer in I've got SMCcontrol running the working fan at 4000 to keep the thing at 50 degrees.
About how old is your MacBook Pro?

If under warranty, take it to an Apple Retail Store, you should be able to get it replaced.
