Thanks Lloyd, judging from the show models I walked through at the show I attended prior to purchase id say mine is normal just never had ANY noise on my old 97 unit, so just curious and yes I have begun the process of replacing with LED
thanks so much for the input everyone. I certainly don't plan on modifying anything and voiding the warranty so I guess LED it is. my initial thoughts was a larger fan probably cost all of 10 dollars, LED going to be upwards of 2-3 hundred (for good ones) I already purchased some from M4products and am very happy with them.
