Making funny noises

i have a vendo h128a coke machine .
the other nite it started making a rackety clanging squeeling singing noise .
i think it might be the barrings in the fan going out  but if its not  could it be anything else ? that would do this? if anyone has any ideals please let me know
thanks jo  '>  '>

How did you come out on that noise,  was it the  fan
that would be my guess .
