If heat is your problem, then you need a fan with 200 to 400 cfm (moves cubic feet per minute, there commerical and a 400 cfm fan is about 6ins in diameter) it will literally suck the heat out of your cpu, with dry ice in front of your air intake a 400 cfm fan sucking from the back will cool the cpu, or pack the cpu in dry ice (this method is dicey though, use caution, I used this method to cool down the bunnies on 100degree days, a pan of dry ice above their cages, cold air would drop down to keep them cool), also render at night when the temp drops a few degrees...just my two cents
