CPU generates a lot of heat, and even with a good heatsink hot
air can get bundled up in the top of your case. I have found
that a slotcooler, pointed upward has not only lowered my case
temperature but also my CPU temperature. I found it to work
the most effectively under my AGP slot, cooling my Geforce and
blowing cold air upward towards my ram and CPU. The slot cooler
used in this guide, is the ever-popular Super Slot Cooler. This
is easily obtainable from www.thecardcooler.com.
Not only is it powerful, moving air at 42cfm, it is also rather
quiet. The unit only produces 26 decibels of noise.
slot cooler push's air under neither your video card, cooling
the chipset and ram, as well as blowing cool air upwards behind
the power supply to the CPU and RAM.
