so I'm planning to retrofit ten CREE high power LED engines into the foglights

These things at 1000mA can reach a blistering 70c in under ten seconds, so that nessitates some air cooling, at least. These LEDs can be driven pretty hard, producing 220 lumens at 1 amp, or approximatley 1100 lumens per side.
I have approximatley a 2x6" area to work in for the foglights, and I wanted to put perhaps three 2x2" peltiers on there to keep the temperature below 20c if I could. Copper is getting really expensive, so I would machine my blocks from aluminum.
Would I need to run antifreeze in my loop if I also use an aluminum heatercore? I figure aluminum on aluminum action won't lead to corrosion since they're both the same metal, am I right?
If this little experiment works, it could potentially pave the way for an LED headlight retrofit for my car, instead of just fogs
