Heatsinks don't really have a power limit right? THey just keep getting htoter and hotter right? I got some bolt-on FET modules and a thermal resistance that I need for them, but the only heatisnks I can find with a low enough thermal resistance are light enough and the right size is for BGAs. The FETs themselves dissipate 10W at maximum (I have no idea if BGAs might dissipate more or less power- they might since CPUs might dissipate 100W) and the heatsink's footprint itself is not dissproportionate large to the contact area with the FET.
As long as the heatsink's about the same size as the contact area, and the thermal resistance is low enough, I can pretty much run whateve power I need through it right?
