ZTE Shows Off Immersion Server Liquid Cooling at MWC
-
The biggest issues with liquid cooling involve actually cooling down the liquid, and making sure no contaminants get into the pool.
The liquid naturally doesn't allow electricity to jump or arch, but getting dust particles into it could cause massive issues.

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.

The question becomes how do you handle the dust particles and such in the air that cling to said ram chip, as @DustinB3403 mentioned.

Could easily have a filtration system.

If you have the money to invest in a liquid immersion cooled system you had better have a filter system... and a nice clean room with positive air pressure.

Except its filled with ultra clean dust free liquid which wouldnt be if you touched it.

Liquid cooling is done to save money.

And it would have to be drained. Then filled up.

Why?

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.

Why wouldn't it work?

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.
