Liquid nitrogen

[Alexandrovichenn]

Why? Do you just put it through your water cooling tubing? It makes your PC super cool? Why? In what situation would you need it? Should I get the new corsair CPU block fan thingy?

Pls welp and help me ANWSER all these questions ty

[blu4]

 

This is for extreme overclocks only, liquid nitrogen is not practical in ANY way. You only need it when you're going be going 6GHz+.

troll?

People dont put liquid nitrogen in AIO's they use it for extreme overclocking. Normal people use special liquids or distilled water....

[AnonKraken]

Why? To cool an extremely overclocked CPU
You do NOT put it through water cooling tubing, you use a custom copper "thermos" that mounts directly onto the CPU
Yes, It makes your CPU really cool (LN2 is −195.79 °C/−320 °F)
I don't know what you mean with "new corsair CPU bloack fan thingy".

so it's a temporary thing? And once I oc I can get rid of it? Is it expensive? And 6ghz is it possible or really pushing it?

Linus made a video on corsairs new products and this was one of them kinda it's the best I could find

Dude, just look at that picture- the liquid nitrogen doesn't actually stay there all the time, it evaporates and needs to be constantly refilled.

[Alexandrovichenn]

Blah

No you don't put it in the tubing.

 

There are special metal "containers" you put on your hardware, then pour the liquid nitrogen into the container.

 

It then cools down the container, thus cooling your CPU as well.  These containers are usually made out of very big chunks of copper, and usually in cylinder form.

(The more mass, the longer it can stay cold under load)

 

Here's what an Ln2 "container" or "pot" looks like for a CPU:

 

 

Here's what a GPU "container" or "pot" looks like for a GPU:

 

 

 

The downfall of this is, you have to insulate your parts to prevent condensation.

 

Here are some pictures of what I have to do to run subzero on my CPU:

 

 

 

Once you learn what you're doing, you can achieve results like this!

 

This is just with dry ice, dry ice only goes to -65c or so in the Ln2 container, Ln2 can easily do -190c, but most intel CPU's cannot run colder than around -130c.

 

[Alexandrovichenn]

LN2 in a loop would rupture the tubing almost instantly...

It is prohibitively expensive and difficult to handle, for it to be used practically for cooling electronics.

Usually only used in overclocking competitions and setting records, for the purpose of hardware marketing shenanigans.

So I understand reaching 5ghz is hard so if I got liquid cooling would I have a chance? And since Ln is temporary should I pay a computer expert in this field to cool it with Ln while trying to reach 5ghz?

[You_are_a_cunt]

Because LN2 is so cold condensation happens, since ambient temperature is considerably higher and all the humidity in the air turns into ice on the block.

LN2 also evaporates fairly quickly.

In some countries you need a special license to even purchase it past a certain quantity. Because it evaporates rapidly, you'll need alot of it. Then there's the cost, which is pretty high (again, depending where you are).

Because of condensation and the fact that it'll turn pretty much anything into a solid block of ice, you can't use it in a liquid cooling loop (that would be a. stupid and b. stupid)

Once you OC past 5-5.5GHz you need ALOT of cooling all the time. Overclocking past that point is only intended for very very expensive loops that still can't cool the CPU to acceptable temperatures all the time. Going past 6GHz is pretty much a world championship and is mostly only done by professional overclockers. They only push the CPUs to the limit for a short period, cooling them with LN2 and even that doesn't work that well past a certain point.

[Naeaes]

Liquid nitrogen (LN2) and watercooling work in very different ways.

-Watercooling physically moves the heat from the block to the radiator where the heat radiates out to the surrounding air.

-Using LN2, the heat trasfers directly from the cup used as the block to the LN2 which then evaporates taking the heat with it. 

 

So if you used watercooling hardware but LN2 instead of water, you'd only manage to create high pressure inside the system blowing it up. Probably the extreme cold would break the tubing first but still. It doesn't work.

Even with liquid cooling 5GHz is hard to get to and harder to get it to be stable. I've spent some 150-170 hours trying to get from 4.8GHz to 5GHz and get it stable, with no success. Also, you don't really need 5GHz (I was going for the top 3 in Rookie Rumble on HWBot, went back to a stable 4.6GHz once I submitted the highest OC I could get to be stable)

Ln2 can actually be quite cheap depending on where you are, sometimes less than 1 dollar per liter, and ~30-60L is enough for many many many hours of benching.

 

The expensive part is the pots and "dewar" (the Ln2 container that you use to store and travel with it) 

 

The pots are 200-500$ depending on where you get them, and a Dewar can cost over 300-1000$ depending on size

 

You can actually run very high 6g+ clocks with a good CPU for hours on end, when I recently dry iced my CPU, I was running around -63c @ idle and -55c under load on the Ln2 pot, for about 4 hours straight at 1.6-1.665 volts, and I was at 5.5-6.0 ghz the whole time.  Didn't even degrade the CPU from the looks of it either, because before I did it, my CPU could do 5 ghz 24/7 at 1.33v, and after those 4-5 hours of benchmarking, it still does the same speed & voltage.

why would you go back down and what would you use higher GHz for?

[Alexandrovichenn]

And then it will crash once the LN2 runs out. You dom't seem to understand overclocking at all...

tbh no I don't I just understand that when you overclock it yields better performance hence why you do it, I wouldn't I would pay someone due to my lack of knowledge and not wanting to risk my build

I was talking about reliable OC that you can keep for as long as there's still life in your CPU. temporary OCs are another deal alltogether.

You don't seem to understand overclocking and the difference between competitive overclocking and functional overclocking.

competitive oc: beating records or getting close to them

functional oc: squeezing more performance out of your CPU for whatever tasks you need more processing power.

 

if temperatures get too high for whatever cooling solution you use, you'll end up with a dead CPU, perhaps even a dead motherboard (more often than not).

oh ok thanks and for reliable oc do you think 5ghz is possible on an 6700k with water cooling?

also I would love if you could ANWSER a question no one else will, what's a reliable oc for my 2666mhz 32gb ram if I got lucky for example if lucky = 5ghz on a CPU what would I potentially get on my ram if I got lucky? Same with my water cooled hybrid gtx980ti?

[You_are_a_cunt]

Because OC is specific to each CPU, you aren't guaranteed to get any specific OC. 5GHz might be possible, but not guaranteed. Water cooling is a good option if you plan to overclock.

You don't need to overclock RAM since it doesn't provide significant performance improvements.

 

Overclocking the GTX 980TI isn't guaranteed for the same reasons a CPU OC isn't guaranteed.

 

The way I overclock my CPUs/GPUs is in small increments, generally 50-100MHz increments, along with core voltage increments until I find a suitable, stable OC (which I then stress-test for anywhere from 12 to 24 or 36 hours).

 

 

Don't expect to be able to google core voltage and frequency, set them in your BIOS and have it work. Overclocking is trial and error and each chip has different OC potential (my FX-4300 managed stable 3.8GHz, whereas an "identical" FX-4300 barely managed 3.5GHz on a pretty much identical PC)

Depends on what he's doing, if he's going for benchmark scores, overclocking ram makes a massive improvement to scores.

 

1600 mhz CL9 vs 2800 mhz CL9 in XTU is like a 100 point improvement.
