Dear Romus: Also take note that the HSF is blowing up while the case fans are blowing in. The HS fan has to do more work to blow against the pressure from the case side fans. While the internal temp of the case may drop, the CPU temps won't drop very much. Because of this those fans likely help the GPUs, the PS and any disks in front stay cooler. If they really needed the CPU to be cooler, they would have used ducts to blow outside air through the CPU heat sink. What happens after that is less critical. In fact the upper two side case fans are counter productive. The lower two blow far more air in than could possibly be blown out by the three GPU fans. Thus cold outside air would be blown up past the card dividing the GPUs from the CPU MB area and across the CPU, memory, NB and VRMs. A better place for them would be one on the top blowing out and one more in the front blowing in at the height of the CPU on the MB. Being in that server case one or two DVD burners would be on the top in front and any HDs would be on the bottom. Pete
