trying to build a laptop cooling pad without spending a lot.
on top of that, any suggestions on a AC power source?

the old computer fans can be wired directly to A/C power. I daisy chained a few back in the day for a homebrew heat exchanger - worked quite nicely. New ones, not sure.

i thought they ran off of 12v DC?
or is that the new ones...

Current computer fans run off 12VDC, you're right. I'm not sure when computer fans ran off AC, that doesn't sound quite right to me since the power supply of a computer only gives you DC voltages. Even the fan in the power supply runs off DC voltage. I have a ton of DC fans of all different sizes if you're serious about this. PM me your info.
