i just got a cheap one off of ebay, not even sure what the brand was, but the fans are pretty good, i havn't really noticed whether the averatec fan still comes on alot or not, but it keeps the notebook cool. like i said in the above post i do have problems when i leave it on for too long, it gets really hot at first but then i start having problems. and i've also had problem before, i left it in the car and it was really cold, when i brought it in i turned it on and i had problems with it because i guess it was so cold
