You could still use Peltier thermoelectric cooling at the IHS and move the resulting excess heat via a heatpipe/AiO block.

In principle, yeah, but peltiers (a) suck at moving non-trivial amounts of heat, and (b) add a huge amount of heat of their own. Like, ballpark 10x the amount of heat you're moving.

You could move like 5W and you might have to dissipate 50W of heat total. Peltiers can't realistically move 100W and you don't want to cool 1000W.

Helpfully, Linus Tech Tips has walked through this particular experiment for you already ;)
