controlling the computer case 'output' air.

I have been trying to make my motherboard temp (ASUS P4T) to come down from 34C when idle for a week now.

I had the same stuff inside a Xaser II and the temp was 24C idle or not.

I looks that the new position of the hdds is not good. I have 3 SCSIs and 1 ide, you can imagine the bunch of connection cables living in there. The room temperature must be around 20C.

What is more curious is that even with the side panel open, the temperature does not go down substantially.

BTW Thermaltake were nuts to lead the hdds so close to the side panel; it is very difficult to slide the panel close due to the cables and more due to the power cables hitting the panel.

Any ideas?
