Check it, Rev2! I've spent the last couple days playing with this pot on dry ice and LN2. Review will be available later next week but let's just say my F1EE is nervous.

here are some vids, These are gomlers videos not mine

Glowing review so far.

[Assassin48]

Well its up on koolance website with pictures of the unit

Its starting @ $170

dude that pot is ridiculous.... i want one!!!! maybe i need to make a for sale thread and stop trading hardware :ohcrap:

[Assassin48]

from what he said in the post it looks like its almost as good as the f1 pot for $70+ cheaper

[Buckeye]

What does Vince sell F1's for now adays ?

My F1 sits on the shelf and hasn't been used in a long time.

not used eh? :thumbsup:

i may have to bug you later

[Buckeye]

Yeah the Phantom handles all my needs and does a better job at it.

exactly what i was thinking LOL

ill wait and see the performance of this pot compared to the f1

Koolance pot will not hold up under LN2, its really for DICE. But then there are far better DICE pots than this one.

[Assassin48]

which pot would you recommend for dice on an i7 rig ?

i currently have a dragon evo pot

[Buckeye]

Look around for used ones. They should have the copper bottom, alum tube design, be big Dia. and tall.

Reason...

Copper tubes are not really needed in DICE and just add extra expense.
What you want for the base is to hold a fair amount acetone as that is the medium that absorbs the heat. The pot should also be tall to help control spray and foam so it doesnt get all over the place.

The biggest mistake I see people do with DICE is fill the pot up with big chuncks of DICE. You end up with big pieces of DICE up high in teh tube and not touching the acetone forcing you to have keep pushing it down or breaking it up.

Far better to bust that stuff up into powder. You will get much better control of temps and not have to keep stiring up the DICE mix.

I have used the standard F1 with DICE and it simply is to small for good operation. If its hard to keep the pot at max temps then the pot is wrong.

These things are tools to use for cooling, just as there are better water cooling blocks the same holds true for LN2/DICE pots.

The Phantom pot is an excelent pot for DICE if it has the Alum tube. Why... It's large and that keeps a fair amount of acetone in the base area. Its has a large Dia and tall tube which makes it easy to add DICE and control the spray and foam issues. The base design does just what it does with LN2, moves teh cooling medium around, has a huge surface area and huge number of sharp edges for transfer of heat into the medium.

I have no clue why Gom said the F1EE should be nervious, its a very bad comparision and perhaps just a marketing jab. I think there is more going on in the background than is being told, well I know there is, but don't want to get into all that here. The people in the know can speak for themselves.

This is an example of a good DICE pot.

[Rogue210]

Thanks buckeye that was really helpful!!!

[MaadDaawg]

just looked and the F1's are listed at $265, or approx $95 more than the Koolance v2. Could be 1/3rd the cost of a dewar. Want to read the reviews before jumping, and ummm... if anyone wants to sell a used F1 let me know :D

Just talked to the local LN2 guys at AirGas and they quoted me a sweet price per liter if I rent a 160 litre dewar for a buck and a half a day... decisions decisions :Dizzy:

Everyone has nice Airgas guys but me :this:

Back when I had the 160L and 230L here at my house they set me a bill for $100 for each Dewar, worked out to about $10 a day just for Dewars :Dizzy:

[MaadDaawg]

OMG :eek:

An old friend of mine is a VP at Airgas in Calif, he called on my behalf and they'll give me the 160 litres of LN2 for $62.50, which is a lot cheaper than they quoted me before I got the "friends and family" discount :D So rental of 45/mo and deliver of 25 bucks gets to over $100 - so it'll only be worth it if one refill lasts several months.. which prolly won't be the case :ohcrap:

[MaadDaawg]

Dude, why'd you keep your temp around -80C in the video's ? was it strictly a cold bug issue or are there limitations to temps due to the pot's design?

[Buckeye]

Are you asking me ?

[MaadDaawg]

lol no, sorry Buckeye.. I suspect your temps are significantly below that with that Phantom of yours ... I am SO envious, but then, I'd cold bug out faster than you could say.. umm.. cold bug?

Was asking Assassin, in his YouTube videos he was looking to hold the temps at around -80C, and was pretty successful with it.

[Buckeye]

Its not that hard to hold a given temp.

What I suspect that he was doing was one of two things, the CPU cold bugged not to far from that, or he didn't want to go colder to show that it fell apart with load handling.

Alum tubes and LN2 do not mix all that well when trying to hold temps. It will transfer the cold very quickly and then blast back to the heat load, or a extremely high swing compared to masive copper pots. The main reason why you don't see any LN2 pots made out of Alum.

Instead they use a copper base and then a Alum tube to save costs and it becomes very hard to machine the inside of the pot when its all one piece with a long tube.

The Koolance Rev2 pot is 3.4" in Dia., thats about the size of the F1 accross its square. It is 6.7" tall vs 5" for the F1. The copper base looks to be about 1.5" - 2" so its not very massive compared to F1 which is about 2.5" of solid copper with the holes in the base part or chamber.

I am not trying to say that it will not work with LN2, it will, but it looks better suited for DICE.

The price point of the Koolance pot is good for some one just starting out with DICE/LN2 and CPU's with warm CB's. It will simply fall apart with no CB AMD chips tho., and I suspect at temps colder than -100c

It would be interesting to see how this pot compares to an F1 with extender tube ;)

[MaadDaawg]

I don't have the knowledge base you do bro, but my thoughts on the height of the base were pretty close to what you just said. Been looking at the F1 and a Alum extension for awhile but can't get myself to pull the trigger :( Would think the bigger copper block would have to work in favor of the F1. But then, I'm running Intel not AMD ???

Any idea where an i7 975 CBs out?

The CB is going to vary from chip to chip. Same thing for the CBB. Bill can answer this better than me, but I think CBB can vary widely from BIOS to BIOS and mobo to mobo.

cb will not only vary from cpu to cpu but you will find that certain boards will have a cold bug of a certain temp, or better yet a COLD BOOT issue....

For example the P55 classified with a clarkdale has almost no cold boot/bug issues whereas every other manufacturer/board is having issues with cold issues :morpheus:

[/EVGA plug]

[Buckeye]

Yeah the 920 D0 I had could run at -130c tho. -110c seemed to be where it liked to run at.

NordicJedi came over with his 920 D0 that ran great on Air but cold bugged at -30c. No cooling I had would have worked with it, except just small amounts of LN2 which was a total waste

[karmakazi]

Those big dewars are pressurized (because they haev a withdrawal system) and have a HUGE static loss compared to a lidded container. If you didnt use the 160L at all it would last ~10 days maybe a little longer. Probably no more than 2 weeks though. On the other hand a dewar like my taylor wharton with a foam lid has held 10 Liters for almost 2 months :thumbsup:

[Buckeye]

That is so ture, also depending on the age and abuse the Dewar has had it might go faster.

Again back when I had the 160L low pressure Dewar here it was in the heat of the summer, it vented all the freaking time. The larger 230L was a high pressure Dewar and it was some what better.

[MaadDaawg]

I asked the guy about evaporation rates and he said about 1% a day, which sounded a little strange cause we talked about the pressure build up and auto venting. I think I'd have to use it constantly to prevent venting, and, much as I might like to, reality would prevent it lol Didn't realize 10 days was about all I'd get :morpheus:

Still hoping to find a smaller dewar and then get him to give me the sweet price per litre he gave me today for the big one.. anyone got any leads let me know..... please :blush:

[Buckeye]

Yeah it can go pretty fast. How ever newer Dewars should be good to go, but these things get pretty beat up.

If you do get a big one make sure you get a hose and defuser. No defuser will equal a lot of gas and will waste a ton of liquid.

http://www.youtube.com/user/BuckeyeVideos#p/a/u/2/JveF60WmiP0

Here is the 160L which did not have a defuser on it, freaking Airgas here goes... oh we dont have those, you will have to buy one. I said screw you guys I am not getting anymore from you, so the next 230L magicly had one :)

Cpt. Cool Himself here Guarding the Dewar with his really Mean Looking Face. I actually had to tip him to let me get any LN2 out.

[Assassin48]

lol no, sorry Buckeye.. I suspect your temps are significantly below that with that Phantom of yours ... I am SO envious, but then, I'd cold bug out faster than you could say.. umm.. cold bug?

I was trying to use my ps3 web cam but it wont work on any live feed :(

Ill probably have a water session this Saturday, followed by a dice session Sunday or Monday hopefully

EDIT*
I got a 2gb for my camera

If you can't do live feed, just do a video and upload to Overclockaholics Channel on Youtube.

Ok, will try to get a decent HD cam for the next sessions.

You guys will see my messy room :laughing:

wow bill i look so tired in taht pic... i may have been asleep on the dewar :laughing:

HAHA no kidding, lets see, work all day, jump in a car for a 7 hour drive, bench for what a full day+, then jump in a car for another 7 hour drive back.

I wish I could have, Mom needed taken care of :(
She did pretty good with you guys all there tho., stayed out of the way and didnt cause me any trouble.

she was so cool... shes sweet

[MaadDaawg]

100 bucks for the hose, didn't ask about a diffuser. Still hoping to find something in the 30/50 litre range

[Buckeye]

You have a really good connection.

Again they wanted me to purchase my own hose and defuser for the next rental... total cost for both 3' hose and defuser... $375

Not to bad of a review.

wtf is this...

Even if this pot isn't able to replace my K|ngp|n F1EE it'll make an incredible paper weight and coffee table decoration.
