I have a 3.4 GIG Prescott socket 478 running on an ASUS P4C800 Deluxe mobo, and in a standard, older Antec case. I have run across ads mentioning that they are Prescott ready. Does anyone know exactly why they are different and in what way? Are they needed or called for with a Prescott? The CPU I have doesn't seem to top 130 degrees F, but I would like to lower that if I could. It is using a retail heatsink and fan currently. Thanks for any input on Prescott ready cases.
