Hello Paul
Thanks for the response. Well is was to late to change my order, so I
ordered the 3.0C and am going to send the 3.0E back.
I probably could have just kept the Prescott (I have a decent case -
Addtronics) but am a little concerned about the heat. You make a VERY good
point about overall cooling.
Thank you very much
Dave

I think I've
