My d620 with a core2 duo 1.83 ghz,a10 custom bios from osx latitude, intel 950 graphics, 2 gig ram, and a seagate hybrid xt harddrive runs at 44 degrees at idle.For normal operation it is fine but last night while encoding a video and burning to disc using imovie and idvd, cpu temps were recorded using istat as high as 76 degrees celcius. This also causes the computer to slow down dramatically. The fan is operating and I can feel the air flow from the exhaust. I was wondering whether the temps are relatively normal, and if there is an issue. I have set the speedstep program from edp to on demand performance. Was wondering if this is a software or hardware issue?Thanks in advance.
