I just installed a Pentium Slot One 1GHZ CPU in my wife's computer and it is running hot. I have a vantec duel fan heatsink and am using artic silver grease. Sandra says cpu temp is 42c and mobo temp is 28c. This is not an overclocked cpu but a real 1ghzer. Same computer with a pentium 650@812 was running at 30c. Do the Pentium 1ghz chips run this much hotter? Your help and advise would be appreciated.
