have an Acer Aspire 5755G and since I also use it for games such as F1 2012 use the notebook is always very hot. Previously had a notebook cooler notebook but where it stand, but he was hot and turned off .Since I have this vacuum fan, I have no more problems. Remains at normal temperature. Fan can be heard, but it does not bother me personally. I had to choose between and the notebook and vacuum fan what do underneath the vacuum fan fits .but it is (different adhesive pads)
