What's the slot on the Asus motherboard that looks like a DIMM slot but is keyed wrong?
They have it on their Dominus Extreme and the other two boards shown in the article.
On the Matrix 2080 Ti:
Wow, that's actually really awesome and pretty innovative... You have surprised me Asus.
And you just have to hand over ONE kidney for it! Even better!
Linus has already taken it apart:
Innovative, but effective? I'd need to see it first-hand to be convinced. The whole point of liquid cooling systems isn't that they're magically more efficient than air cooling systems; it's that they let you take the heat away from the ickle-tiny-hot-thing and move it somewhere you can give it the surface area and airflow it deserves. If your radiator is no bigger than a heatsink would have been - in fact, potentially smaller thanks to the need to make room for a pump and radiator - then there's no reason liquid cooling would be better.
Not quite true - you can get away with a considerably smaller radiator than conventional heatsink while achieving the same cooling potential because almost all giant heatsink stacks connected to heat-pipe assemblies have "dead zones" where no heat transfer actually takes place (or even worse, overlap when the pipes are positioned too close), whereas in a liquid cooling radiator, the tubes are spread evenly over the entire surface area.
It's why you need something like a Dark Rock 3 or NH-D15 just to match a slim 120mm AIO cooler.
Yes and no: a bigger reason is, as mentioned in my original post, airflow. A heatsink on a graphics card - and I'm talking about the top-down stuff, here, not the centrifugal blower ones - has limited airflow because the air comes from the top, down through the fin stack, and smacks hard against the PCB. A radiator, properly installed, lets you blow air in one side and have it come out the other entirely unmolested in a straight, efficient line. Pop the same radiator flat up against a PCB and that's gone.
You can try it yourself: measure your temps with an unobstructed radiator, then pop a bit of plastic with sticky-up bits against it and measure again.
Be careful when comparing air to liquid cooling, though: there's another issue, and that's thermal capacity. The water holds heat better than metal, so an air cooling system and a liquid cooling system with otherwise equal performance will see the temperatures rise more slowly on the liquid cooling system - but also fall more slowly at the other end of the test.
