Skeptical of that. There's only so much you can do against the physics of moving electrons around at high speeds... "Bigger Fans" and "compute density" doesn't change that
I don't have any particular knowledge about oxide's cooling, but think about how bloated and inefficient literally every part of the compute stack is from metal to seeing these words on a screen. If you imagine fixing every part of it to be efficient top to bottom, I think you'll agree that we're not even in the same galaxy as the physical limitations of moving electrons around at high speeds.
If the customers leave these things idle, then oxide is going to shine. But a busy rack is going to be dominated by CPU heat.
