Well, after a disappointing diagnosis on my old PMG5 and thoughts on a refurb, I finally decided to buy a new one. A stock 2.8 8-core config for $2699 with my EDU discount along with an 8GB Touch, which after rebate and resale of the Touch, actually works out to be $34 cheaper than the $2499 refurb I was looking at. Anyhow, picked up my new powerhouse last night and got things set up. However, I'm noticing a brief (2-3 second) "high rpm" fan noise on start-up, immediately after pressing the power button. It doesn't sound like it's out of control nor does it sound like the old full-blast fan noise that I experienced on my old PMG5. It just sounds like one of the case fans starting up and setting itself or something (it's hard to describe a sound!). Is this normal and has anyone else experienced this with theirs? Given how much my new purchase was, I want to ensure that it's perfect before going past those important first 14 days.
