If you just grew from bagseed, there's no telling what the bud you bought was crossed with during pollination unless you know the grower, so it could be a completely different strain or even a landrace strain that might not have much smell or taste.
I have been growing Master Kush for about a year and a half and it really has no smell either, but as someone already said, curing it should help you out. Usually after 3-4 weeks of curing, my MK doesn't smell like much but it has a nice flavor to it that I just don't get without curing.
Also, you should never put a fan blowing directly on drying buds. It will dry them out too fast making the buds crispy, the smoke harsh and the taste not as good. You want them to dry as slow as possible in order for the chlorophyll to break down properly giving you the best flavor. You should put a fan in the room where you are drying to circulate air but don't point the fan at the buds. I dry in a 3x3x8 closet with a small fan blowing up the back wall and my buds are usually dry in 4-5 days at 75 degrees and 20% RH.
Hope this was of some help and congrats on the successful harvest!

If I were to grow cannabis, I would only do so to supply myself and my close friends. Doing this would take myself and my friends out of harms way by knowing the source of our cannabis, as well as take hundreds of thousands of dollars off the black market annually. It would also lower the demand of black market cannabis, and would ultimately help keep cannabis out of the hands of minors.
