I noticed the same sound when i fitst bought my truck with 69k. I asked around because i was worried there was something wrong with my blower but everyone ive talked to says its normal. And mine is pretty loud even after the truck warms up ( i think it is anyway). Have you tried changing your blower oil yet? I believe its supposed to be changed at 50k or 60k. I will be changing mine within the next month, maybe with new oil it will quite down a little.
