Also seems it would be a huge pain in the ass to replace a failed component like a stick of RAM. I imagine the need for changing RAM happens in Datacenters.
Shouldn't be bad. How do you replace RAM normally? Power off the machine, pull it from the rack, replace RAM, power on.
Same here.
And it would have to be drained. Then filled up.

Why?

Except its filled with ultra clean dust free liquid which wouldnt be if you touched it.
Is it? Do we know that?
-
Phase change liquid is so viscous, I bet those ultra clean concerns aren't real. That's based on oil-based cooling, single phase.
-
@scottalanmiller Yes or it wouldnt work. Why do you think you could replace a piece of RAM in a full immersion system without draining it?

Why do you think you'd need to? Just pull the parts out.

-
Remember this is a new liquid being used here, how does everyone seem to know so much about it?

Parts replacement is likely done by lifting the computer out of the tank. you would not want to reach in as your skin has stuff and oil on it.
Process (likely) is Raise and drip,.. remove/ replace, re simmer the system again.

That's what I'm guessing. Might actually be easier than air cooled because of the lack of heavy chassis.

The thermal transfer to liquid is better than air as well.

I've been hearing of data centers that use liquid cooling for most of my IT career. It becomes more economical once you've reached a certain point.
Believe it or not, it's very easy to do with just some mineral oil at home. If water happens to get into the system, it just floats on the top and remains easy to skim off. Dust isn't so much of an issue, with a normal replacement cycle for computers just change the oil when the computer equipment gets changed. I've also heard that plain mineral oil can wear away electrical components. I've never experimented with this myself, so this is all 2nd hand stuff I've heard over the years.

The big bank on Wall St. that I was at put in chilled water cooling while I was there.

That stuff is messy, though. That's where a lot of the hesitation about liquid cooling comes from, I think.

I would really need to see this myself to believe it. Even with mineral oil you need some kind of heat spreader. I can see this working no problem with a modest hunk of copper on the CPU but bare? Yikes.

They show them working with no spreaders on the video. Mineral oil doesn't cool anything like a two phase. It's not "even with mineral oil", because it's among the bad options. It moves heat well, but moves physically very slowly. The two phase moves heat SO quickly.
