okay, probably this issue has been raised many times but i am stuck...

I currently have an intake fan (~30cfm), a cheap fan blowing on the CPU and the power supply fan configured to blow air out.

But the problem is that during hot days (30ish celcius), the temperature of my CPU sky rockets (near 50C). The case temperature is about 39C. The temperature of the CPU is a rough estimate however... i added about 10C to the 39C i measured from a temperature probe i attached to the heatsink. Oh yeah, i have a FAB28.

The question is now how do i get my case temperature cooler... any suggestions would be welcomed. Thanks in advance.
