If you're talking about something like a water chiller system from haliea or whatever their name is then that would probably be easier to deal with as well instead of peltiers.

But if you can find an actual full blown phase unit near you for cheap, that's -40c on tap and is very useful to have.

I think phase difficulty, has been blown out of proportion. Baker was telling me its really pretty easy. The most difficult part is the head and you can buy those from bartx or under the Ice.

Anyways Point is, Aparently if you have any hvac experience. or hell even know how to braze pipes properly. Its not hard to build one yourself. Since shipping seems to be the biggest issue with these things. So if you can build it yourself you end up saving a hundred$+. Just through that. I mean sourcing parts from ebay could save some cash as well probably.

Also repairs aren't that big a deal, or refurbs. So you can save money buying a broken one with the intent to fix it.

you only need certs to do cascades, since it uses a special gas. The one in a SS IIRC is standard and needs no certs to buy or use.

Depends on what the regulations are in your local area, in the UK it's really dumb, you can buy refil cans off the shelf with certain refrigerants but you can't buy that same one as a bottled gas (i.e. a bigger package) since you need a license for it.

I can't remember the exact specifics since I never really looked into it much as I lucked into a good unit for cheap so I'm not really in a position to help in that regard.

I did some DICE last night and was hoping someone could have a look and tell me if I messed up anywhere.

This was my first time, and I think I got a bad mount, because CPU was still hitting 30-40c load temps with pot @ -60 Celsius.
I will try again soon, I've gotta get the mount right next time to get better results for sure.

I want to thank [MENTION=37631]ProKoN[/MENTION] , [MENTION=45442]rtsurfer[/MENTION] and [MENTION=36437]Jumper118[/MENTION] for helping me out with the prep and little tips here and there, appreciate it a lot guys.


I think I did something wrong, because CPU temps were still going positive temps (are they supposed to do this...?)


Big XTU run at 5.3 ghz on CPU, 5.2 on cache, and 2800 mhz CL9 on RAM

You can see cpu hit 39c load temp, yet pot was at -60c, so I believe bad mount for sure.

Just like rasparthe said you definitely should go tighter with the springs, especially with dice because it's not getting everything as cold as ln2 would, where maybe just using pot with it's own weight you could get away with.

I would go halfway down the space on the rods above the hold down bracket.

Also xtu is not the best bench to test a good mount, it's so stressful that the temps will be a lot different than most other benches. With xtu and dice temps it wouldn't be weird to see positive temps under load.

I always let the results talk for me. If I keep scaling, I don't pay any attention to the temperature readouts when I'm subzero. Before Haswell, software readouts were completely unreliable when cold. In fact, I'm still not convinced that they're accurate in Haswell and Skylake.

pay attention to temps, they got higher clocks with helium:thumb:

http://www.bit-tech.net/hardware/cooling/2010/07/20/hailea-hc-500a-water-chiller-review/2
790w of phase,
guess that I will need to have at least 1000w to match the cooling of it.
to me it feels like peliters will match phase if the power is high enough

I think I am off topic too? I think i need to stop lol

Why not just get something like this dude http://www.pcfaster.com/static/img/knowledge/image/img1409746816064.jpg

Like I said previously, no point wasting time with peltiers, they consume way too much energy to be useful.

Oh yeah, I use LN2 a couple of times a month. My point was that I ignore software temperature readouts if my CPU is scaling like I expect it to... i.e. my 4770K is doing 6GHz at -130°C, no issues there. If it was stuck at like 5.1 or 5.2GHz, then I would be suspect and start looking into things.

Only one of my lga 775 chips tracks temperatures reasonably well, and that's my Pentium d 820. It reads down to at least -60C, but only bout 60% of the time.

It's also motherboard dependent. My X58A-OC was pretty good till around -80c to be fair. That was also comparing to my thermometer, of course I would never use it as my reading and always back myself up with a proper K probe smile.gif
