i recently had an injen cold air intake installed in my 2005 mini cooper R50, and ever since, it sounds like my aux fan comes on all the time. but only if i've been driving a while and maybe run in to grab a pack of smokes and come out, and there is the high pitch whining of the fan, after idling for maybe 5 minutes? Anyone have any clue? oh! and then it turns off after driving for maybe 5 more minutes
