similar to when holding paper at fan(home thing) blade at very low speed..
is this sign of bad timing belt or serpentine belt??
my car is around 89,000miles=143,000kms..

That's a common problem with cars bought from California :lol: just kidding , just teasing you cause I've never been to Cali
Never heard of a timing belt to make a certain noise when being worn , the serpentine belt should maybe slip and squeak ...try some beltdressing to see if the noise goes away or changes the tone in any way . But I would also suspect an idler pulley or belt tensioner bearing
