I used a duo 280c for a whole year before I discovered that there was NO heat transfer pad between the CPU chip and the stiffener. It never gave me any problems, and according to the temperature control panel module it didn't run very hot. I have since put the correct heat transfer pad in place and it is only around 5 to 10 degrees Fahrenheit cooler. Greg ---------- Duo/2400 List, The friendliest place on the Net!
