This device is made of an oak kitchen drawer insert (for cuttlery). I cut it slightly so the pcmcia cards can be inserted....and I cut holes in the rear to match the output slot of a USB powered CompUSA plastic laptop cooler. The cooler wedges in the oak box using glued-together pieces of safety mat foam. I spaced the cooler up high enough so the rear ports on the laptop are unobstructed.
The laptop just sits on the cooler, partially wedged in by the foam...removes instantly. Amazing temp drop....at max CPU usage I now measure 36C, with the CPU fan barely turning. The little 40mm fans run on 5V, and are somewhat noisy. With a slight voltage reduction, they should be quieter than the original setup. With these fans running, the CPU fan slows way down, and is hardly audible.
This setup is much more stable than just sitting the laptop on the bare cooler.....no tendency to slip off. My lap is now very cool.

edit....I lowered the voltage to the cooler fans down to 3.25V. They still start ok, blow less air, but the temps are the same as at 5V. But now the whole thing is virtually silent on my lap.....and completely so at arm's length. Great......
