Anyone ever done it?

I am seeing a lot of kits and DIYs, and I just so happen to access to liquid nitrogen every day?

I also am doing some heavy processing on a 3.3 machine and think I could ramp it up?


Sounds fun!.

looks cold

Typically those kits are for competitive overclocking (benchmark scoreboards, raw CPU speeds, etc.), rather than as a daily driver. Fun to mess around with, but not in any way practical. There are still some sub-ambient, phase change cooling kits out there, but they carry many of the same issues with condensation that LN cooling.

You're best bet for a daily use computer is probably an open loop watercooling setup or maybe something like the immersion cooling rig posted above.

Liquid metal cooling or gtfo

I've got liquid metal on my delidded 7900X between the die and IHS. Almost 20C cooler temps than I was getting with the stock Intel toothpaste-like TIM and allowed me to run it at 4.7Ghz on all cores full time.

Back before marriage, I was into overclocking. I used to mess with liquid nitrogen and also had a vapochill case for everyday use. Unless your really extreme a good water cooled system works just as good.

So when you stop using it, all that frost build up melts and shorts out your mobo?

That definitely can if you don't insulate properly or pour too much LN into the cooler at the wrong time.

Some motherboards, like the Asus Apex series, have moisture sensors all over them for use with sub-ambient cooling like LN that can give you a warning or even trigger an autoshutdown to protect the system.

They need to purge the surrounding air with CO2 or nitrogen to remove the water vapor and prevent condensation.

From what I've seen in a couple kits, these LN coolers have an evaporator surrounding it to "burn" off the condensation. Interesting technique.

I'm doing 3D processing and agricultural photogrammetry. 18 hour processing days are a good day, 36 for 3D.

I was thinking of making a drip to keep it cool? I'm not going for -175 degrees consistently like some of theses guys. Just want to push the limit a little for faster processing.

I'm building a new processing rig, so my current one is open for experimentation.

In all seriousness, LN cooling would help my bottom line, the processing is what is holding me down!

Really cool, semi-closed loop LN cooling system demoed at Computex by EVGA and Kingpin.

Nice, 75% LN2 recycled. That is awesome.

Still looks like lots of condensation can build up.

Yeah, you can see then heating elements all over the system to minimize condensation buildup on the main components,

I'm not up to speed on our processing equipment, but our 8 petaflop Cray system didn't even use nitrogen cooling, and these systems processed jobs that took 3 weeks or more to run 24/7.

Is nitrogen cooling really necessary?

So cold you have to heat it up???

How do you cool the heating elements?

Seriously though, you just want to cool the CPU with the LN. The warmers keep things like the PCB and back of the socket from going sub-ambient to prevent condensation from forming on them.The warmers don't get more than warm to the touch (so don't require cooling) and are a better solution than a crap ton of neoprene (or similar) insulation that is a PITA to remove and reapply if you need to swap parts that you'd have to use otherwise.

Condensation build up = dead mobo/CPU/etc

That's because the Cray was using a bunch of slower, more efficient processors in parallel to get to that 8 petaflops of computing power. Some workloads don't work well in parallel and a system like a Cray would be wildly inefficient to process them in terms of cost.

Higher clockspeeds benefit those processes that don't run in parallel very well (or beyond a certain point). When you really start pushing silicon beyond the speeds it was designed to run at, it becomes less and less efficient, which leads to significantly increased heat generation (and therefore significantly increased cooling needs).

Right On tamusc.

The photogammetry software does not support parallel processing. The closest it will support is a GPU CUDA processing based systems (which I am about to start a thread on). I believe it will not even use more than 2 cores for processing so even multi core systems don't always hold an advantage.

Besides, don't think a Cray super computer is within my budget. Just a picture of their supercomputer cost $10 bucks! https://www.walmart.com/ip/Cray-2-Supercomputer-Photographic-Print/656231108?wmlspartner=wlpa&selectedSellerId=6720&adid=22222222227150149666&wl0=&wl1=g&wl2=c&wl3=262120584628&wl4=pla-461524696044&wl5=9027902&wl6=&wl7=&wl8=&wl9=pla&wl10=117018889&wl11=online&wl12=656231108&wl13=&veh=sem

Lol

On a serious note, I am processing 80 gigs worth of data on test bench build rig with about $1000 in components, so I am pretty low on the market for my first build. They are trying to develop a server based program for processing but it is not out yet.

I see. That makes sense.

the answer was 42, wasn't it. Pretty sure Deep Thought was a 486, so it took a little longer than 3 weeks.

Exactly how much are people overclocking these damn processors that they need liquid nitrogen?

der8auer got the new 8086K (basically a binned, anniversary edition of the 8700k just released in honor of the 40th anniversary of the 8086) up to over 7.3 GHz using LN. That's a 2.3 GHz overclock from the stock 5.0 Ghz for that CPU.

A bit more in depth video on that (semi) closed loop LN cooling setup in action.

That is amazing
