I am very inexperienced technically but have recently put together a new machine with the help of my friend so I am starting to learn. I have read several things about the hardware I have and I am starting to worry. I have a Intel Pentium D 915 Prescott at 2.8 GHz that at idle seems to run at about 60 c. It gets up to 70 on a regular basis and from everything I've read thats way too hot. I do have arctic silver 5 thermal paste on it with a good gaming case. When I first used the cpu it was at about 40 degrees and now a week later its jumped considerably. I also have RC1 version of vista currently and it seems to be going very sluggish at the moment. I could play oblivion at first with decent graphical ratings but it has for some reason become almost unplayable at about10-20 fps. HELP! anybody any suggestions for anything, primarily cpu temp.
