Well, I purchased a Volcano 7 for my Duron 1ghz. Man what a huge monstrosity this thing is! With my Abit KT7A MB, I had to remove the power supply to have enough room to use a screwdriver to get it seated. I went ahead and used the TIM that's already on it, but I did purchase some Silver Thermal Compound. I haven't put it on yet as I wanted to see how well it faired with the provided TIM that is already there. I'm currently hanging around 38c to 39c with the CPU which is a BIG improvement over the 63c it was doing with the older fan and heatsink, which curiously, was as Tt heatsink and fan. Must have been a discontinued model or else, an OEM version. In any case, how much more improvement will the Silver Thermal Compound help? It states it will improve it by as much as 10 degrees C, but is that true? It's Antec's compound.
