Started college in 2004.  This is when I bought this EXACT FAN. The fan made it through nine years of smoke, filth, dust, and spilled beverages.  Cleaned between 3-6 times, giving you that range because I'm not sure.  The motor popped a few days ago.  I turned it on and it was operating at half mast.  Being lazy, I left it on while it groaned hoping it would work.  It died.  The fan lived for 9 years.
