Review on 🌬️ Efficient Cooling: Aluminum Heatsink Peltier Chipset Cooling for Optimal Performance by Jonathan Jensen

later I don't know what to say, it's a radiator. The dimensions are correct, the underside is quite flat, but I would still recommend some kind of thermal paste. I used to build a small peltier cooling unit, it used about 8 watts, everything stayed cool with a 40mm fan attached. Got about 90 degrees f(30c) max.
