I'm up here in northern PA and today was the first real warm day. I think we were in the mid 80's. Anyway I noticed my 722 fan kicking on quite a bit. At times it seemed to run for 15-20 minutes straight. Pretty loud too. It's not enclosed and I don't have anything sitting on it, so it does have room to breathe. Anyway, just wondering if this was normal as I haven't heard it get this loud since I got it in January. I have heard it rev up in the early AM hours during updates, but never during the day as it did today and yesterday. I've read a few older threads, but didn't know if outside temp plays a big part in this things functioning.
