Hi, I have 2011 dell studio 1558 with core i3, 8 gb ram and 128gb ssd.i noticed that my CPU fan runs on high speed most of the time., I searched around and saw that it could be due to the bios or the video driver. In my case I have the latest bios.. a12 and my system only has the intel graphics card. I even opened up the machine cleaned the dust.. But it did not help.. My core temp shows around 55 degrees.. Any help would be appreciated
