Okay so i got a brand new asus gtx 550 ti a cheaper model cuz its 192bit, when i run any 3D game i got temperatures up to 80 c now i made a hole in the bottom whit a pipe so all the hot air would flow out from the gpu and still getting up to 75 c at full work so now im wondering any ideas to cool it down? and is 75 c bad and will it minimize the life lenght of gpu? the gpu fan sounds pretty terrible at 75 to good i got my surround sound
