Buying a Hardcore LN2 Pot

[Mutant_Tractor]

Hi guys,
Im getting into the extreme overclocking end of things as i recently got a SS Phase from LD on here
I have been researching and looking into LN2 for ages,
I wanted to know where is the best place to buy an LN2 pot?
I found www.kingpincooling.com and www.ln2cooling.com, but most people seem to buy pots from members of forums and such,
What in your opinion is the best performing LN2 pot, regardless of price?
Im going to skip DICE and go straight to LN2,
Cheers Guys!
Myles

Block Suppliers:
www.kingpincooling.com
www.ln2cooling.com
Koolance
Otternase
Pitores #2
Bartx
Duniek #2 #3
Little Devil #2
Ryba

When i get time ill sort them into entry level/amature/pro pots,
Ill try get some LN2 suppliers up as well as some dewars

K|ngp|ns F1 pot is a really good pot and alot of members reccomend it, K|ngp|n also owns kingpincooling.com, for other pots look at LD, Duniek and Piotres

[Mutant_Tractor]

Is there any comparisons of this kind of stuff? iknow its really hard to compare due to the large amount of variability with the LN2 different types of ethanol etc used,
I bought my SS from LD so ill check his stuff out,
Does anyone have a reccomendation on what the best in their own experience is?

[zalbard]

F1 pot is the best one, hands down.

Unfortunately this isn't a very straight forward answer. The mainstream pot to own is the F1EE from Kingpin, it is popular for a reason. If you are benching chips with a coldbug the high mass design of the F1EE gives you a huge buffer to work with and eliminates the need to be very well practiced in pouring LN2. If you are benching chips without a coldbug then you want maximum amounts of surface area with minimal amounts of mass. For this the Venom from Kingpin and the LN2Cooling pots are perfect options. A third option is the Koolance CPU-LN2 Rev2 which sits between these two design concepts with a moderate amount of mass and a moderate amount of surface area and. These are the only mass produced pots that I know of with repeatable performance. I'm not too familiar with Little Devil, Duniek, and Piotres' pots due to their location but I don't believe any of them have been constantly reproducing a single line of designs or have websites available for taking orders. The only pot I used from those three was a two piece dry ice pot back in 2006 or so, so no experience with them.

This is all gathered just from my experience with the above pots. I suppose we need a buyers guide for LN2 pots as we have these "I want a xxx pot" popping up frequently enough.

Not to diss the F1.. but the line of extreme pots from otternase are better. but they also cost considerably more.

[Mutant_Tractor]

Sorry if this is a very stupid question but what is a coldbug?

So say if i was to want at some stage to get very heavily into LN2 wouldnt it be better in the long run if i bought a lighter pot so that as i improve i will get better results from the pot?
Ill google otternase now and find out what his/their ones are like

[Bitemarks666]

a coldbug is where the CPU doesnt work as it should under a certain temp and sometimes doesnt even boot also known as a cold boot bug meaning you need to boot at a higher temp the drop the temp as the CPU heats up
if you are getting into LN2 heavily you need a heavy pot as with light pot you will get massive temp swings as you go from idle to load and you cant control the temp aswell wioth a light pot

[Buckeye]

Cold Bug or CB is a temp that a CPU stops working. This will be different for every CPU.

This is why you see poeple using a torch or hair drier to warm the pot back up as they have gotten it to cold and the CPU will not run.

Example: I purchased a Intel 920 D0 and run it under LN2, it could boot all the way down to a temp of -130c, any lower and it would not boot. A friend came over with his 920 D0 that worked very well on Air Cooling, but saddly would not boot colder than -30c.

Some CPU's might be able to boot at at a given temp, but after you have gotten to the desktop it can run colder.

Do your research on batch numbers and you will be treated right.

Some CPU's run very well on Air or Water Cooling, but fall apart when extreme cold is used. While others run crappy on Air or Water cooling but really shine on extreme cold.

I have several ES CPU's that cold bug just below SS Phase temps so there is no real point in running them under LN2 as even with DICE they will not boot.

Sorry Bite... posted at the same time.

[Mutant_Tractor]

Ahh okay cool,
So basically if im not hit with a coldbug then the best thing is a heavy pot i.e. kingpins F1, Duniek's PatchPot, I also found another pot, i cant remember where weighs something like 2.2Kg :P
Looks beautiful, does the same hold true for GPUs as CPUs?
In their time off they can be ornaments in my room
I take it the heavy pot = better cold/heat retention and thus less drastic swings?

[Mutant_Tractor]

I have an Intel ES 980-X @ 3.06 its the Q3QP i think, thats the main reason im trying this stuff out hopefully i can get some great results out of it...
Also, im in Northern Ireland, does anyone know is a license required to buy LN2 in the UK?
In certain places in the US it isnt required yet in others it is so im not so sure here, I ordered my bro one of LD's SS for his new build (EVGA E759 + 920 C0) so hopefully that wont suffer from such problems when booting with the SS

EDIT:
Sorry DP

EDIT#2:
I think ill start compiling a buyers guide type thing in the 1st post

[Bitemarks666]

no problem Buckeye, i think you explained CB better anyway
you dont need a licence in the UK but some places will come out and inspect your storage area to make sure it is within all H+S regs. you should have a look over at benchtec for the UK benchers

[Mutant_Tractor]

I saw all of those guys prettymuch own the UK benches on HWBot, I joined XS group though
I dont know how this is relevant but this is what happened when i put my 980-X in my laptop :P

I need one of those special stroage things, the name escapes me at the minute though

[Bitemarks666]

dewar

[Mutant_Tractor]

Thats the one, ill ask my uni and see if the chemistry department would be willing to donate some LN2 for the name of science
Not likely though

[Bitemarks666]

I have heard of ppl buying it from unis instead of companies like BOC for a bit cheaper

[Mutant_Tractor]

Well i might try that, ill need a dewar first so ill have a look for them,
Updating the first post with details of block suppliers

[Mutant_Tractor]

Updated 1st post with suppliers,
Finding it hard to get suppliers of LN2 at reasonable prices, same as dewars, rediculously expensive!

[Bitemarks666]

yeah dewars are crazy expensive over here but you should have the option of renting one from the same place you get the LN2

[Mutant_Tractor]

Cant you use a really good insulated flask to do it?

[Bitemarks666]

well what happens is you get a dewar to keep the LN2 in and you pour into the flask then into the pot, as the dewars are nomally 25 litres and I dont think the LN2 supply guys would be to happy about having to fill 25 1 litre flasks plus flasks dont keep the LN2 fom evaporaing as well as a dewar

[Mutant_Tractor]

Ahhh okay, i saw a guy on ebay that had 2x 10L dewars for £50 + £6.50 P+P each and i missed them
Should have kept a better eye on them,
That was back in december i think, they dont come up much on ebay :/
At least not in the UK

Edit:
Heres the link:
http://cgi.ebay.co.uk/Liquid-Nitroge...item414af7c07b

[Bitemarks666]

damn it why did I miss that

[[XC] gomeler]

You should be able to find a 20L to 30L dewar for under $400. Look outside of ebay for stuff like lab surplus, liquidation sales, and the like.

[Mutant_Tractor]

Still no luck finding dewars
Well... i found them but its DAMN expensive
Id be happy to get my blocks sorted first :P
