Thread: Submerged Liquid Cooling

So with a boiling point of 34°C it would boil constantly on a hot summer day. Ok, maybe british summers don't count ;)

There won't be a situation where the liquid has completely evaporated and turned into a cloud of gas stuck in the radiator - at least if the setup is done right.
In any case, air cooling has a delta of 20C or higher (20 above ambient). An air cooled PC would die in a room that has a temperature of 40C (who likes to sit around in an oven anyway?).

They don't have a peltier condenser in there as far as I can tell, it's just air cooled. So it can't go below ambient.
And saying an air cooled PC would die in 40C temperatures is just wrong.

By the way: PCs even run in india. They have to. Where else should all the excellent programmers come from :D

At a recent conference, I talked with a few guys who are in charge of data centers/"super computers" at various government labs (and one guy who we were pretty sure worked for Google but wasn't attending in a professional capacity) on cooling and the like.
Submersion cooling is cool (hee hee) but has severe drawbacks.
Submersion cooling in particular works REALLY well for things that generate a lot of heat and are almost never touched. Why? It has the same "problems" as liquid cooling cranked up to 11. If you have to regularly remove and inspect components (so not us, but definitely "industry"), you need to redo the seal on the tubes every time. While not a horrifying ordeal, it definitely adds to the difficulty and lowers efficiency.
As mentioned, submersion cooling cranks that up to 11 because now you either have to drain it or (if you have the right kind of connections and the right kind of liquid) reach under-liquid and fiddle with crap without making a mess (so probably still draining it :p).
So it basically boils down to ease of maintenance VS costs and more and more these facilities are being built from the ground up with cooling in mind. Over the next decade or two we might see a shift to submersion, but the big issue is the long-term viability (as has been discussed).
Of course, for the consumer it is overkill. Nifty, but overkill.Steam: Gundato
If you want me on either service, I suggest PMing me here first to let me know who you are.

I don't get your last reply. By idle temps you mean room temperature or CPU temperature? Because if it's a CPU temperature I don't see that happening unless cooled with a Peltier element, which is really pointless. And if it's a room temperature it's a pretty steep gradient from below 20°C inside to 30°C outside and I doubt that it's common in India (it'd be pointless too, imho).
To the original topic: It's certainly an eye catcher. And that's all it is. Because it's also very impractical.

I vaguely recall many many years back seeing a Cyrix 6x86 running in veggie oil.
Can't help but think that the age of massive cooling is coming to an end however. Massively clocked 180w CPUs only need substantial cooling because they're turning 90 odd of those watts not into pretty pixels but heat. A (physically impossible) 100% efficient CPU could have no heatsink/cooling whatsoever and run full pelt at ambient room temperature.
Progress in the last few years and what looks to be the trend for the next few years looks significantly skewed toward efficiency. So in the future you'll still have 180 watt CPUs, but 170 of those might be used for explosions and only 10 wasted as heat. At that stage any old passive heatsink off a 386 chip may well prove sufficient cooling.
