I have a vantec FCE 6030D with a 7k fan. (LOUD)!! The temps for cpu are 45C and MB temp is 35C. Is that too hot for a T-bird 850? Is there something wrong with the 850 Athlons because i changed it two times and they are the same temps. I have 1 80mm intake fan and two small exaust 40mm fans. I don't have space for a 80mm fan in the back. Don't want to cut holes. Do you think that i need a more stronger intake fan?(Sunon or Panaflo)??
