Fridge CPU cooler?

If you got to the ible on making a usb fridge http://www.instructables.com/id/5-Mini-USB-Fridge!/ it tells you to find an old camping fridge and take out the peltier/heatsink unit, can you use that unit to place on a CPU of a computer or laptop to cool it down?

I wouldn't. There are Peltier coolers and heatsinks designed for CPU's, but there are risks; primarily, if the cool side (against the CPU) is lower than the ambient air temperature, condensation will form on the surface. Water and electricity, obviously, do not mix. Of course, if you're overclocking the crap out of your CPU and it stays above ambient air temperature at all times, then this isn't a concern. Or, if you have a dehumidifier in the room that can guarantee 0% relative humidity (which might be hard, not to mention make it uncomfortable to breathe). Again, I don't think it's worth the risk. If you need good cooling, invest in a good water cooling kit; they're not too expensive anymore, and if you're competent at installation and follow directions well it will provide excellent cooling and be completely safe.

if you want to use peltier, why not use it in water cooling?
in water tank (mostly it comes in metal), you can attach in the upper of the tank. so, the water can recycled (cold out, hot in). although you need some encapsulation in the pipe (since you didn't want some drops damage your pc ;p )
