    no need to be a smartass, if you think there's somthing wrong with the system im happy to discuss it & correct.

    As far as im concerned, I think that -25hg @ -54c is good for a free compressor :thumbup: & I highly doubt it will die after 3months... & if it does, i've got 10 just like it ready to replace it with ;)

    Why on earth would I need to resize the capillary tube?

    This system will be benched very shortly under load, & I like posting my results as I go. If you dont like it, dont read it.

    this is totally going OT

    ......back to that nice phase system...............hey C-BuZz what chip are you going to test it on now.......bloody AMD CPUs in cold bugs=not much fun in real cold :(

    looking good there cbuzz. (dont need "-" ie -25Hg there cbuzz, once ya reach 0psig, the letters change to Hg which means vacuum)
    at load that 25Hg will rise in pressure, more like 10Hg and -50c at load. 25Hg wont have muc capacity as there is hardly any gas in the system at all, static charge will be like 60psig.

    Are you going to completely enclose that system??
    if so you will need to either draw air through the condenser then have other fans on other side of case to suck air out.
    Or if you can have fans on other side of the condenser so it draws the air out of the case through the condenser can get away with not using more fans.
    I found this out the hard way with my water chiller, after a few hours its like 50c plus inside box. after reversing fans box kept close to room temp :thumbup:
    looks like dinos22 is gonna have a sweet system there cbuzz.

    How are those temperature controllers going any results yet? Have you thought about using one of the commercial units to set and monitor sub zero temps.

    thx for the tip :o

    static high untuned is around 100 so pretty close guess there.

    will be tuning underload today so Hg always changes. I still like to see how low she can go unloaded.. Gives me that warm fuzzy feeling inside..

    yes going to be completely enclosed. I dont think heat inside the box is going to be a prob, notice the 240v fan bolted directly behind the compressor :thumbup: with the two 120mm blowholes directly behind it hehe, works a treat so far even without the sides attatched.
    I was thinking of adding 2 x 120mm suction holes at the front, but not to sure if i'll need them? might be a good idea for fresh airflow from front to back of box as the 240v fan is pretty powerful.

    still waiting on my shipment of blueice LCD's from the states. They must have been caught up in the Christmas rush.

    Would never use the commercial unit, they are way to expensive & dont do what I want it to do.

    yer.. I gave it another crack & finally got the 144 to boot, doing some occt testing at the mo. Man can only bench @ 2.5Ghz/1.6v with these temps. Both optys r crapping out :(

    Personal record unloaded hehe

    started out @ -18c, I was tuning the system most of the way through the test. by the end of the test it was @ -24c & still dropping. the graph looks funny :p then drops to -38c/-40c at the end.

    i'll post result pic up as soon as I put the system back together & online.

    It's a damn shame those optys are cold bugged :( If my 146 goes alright under DICE, considering we probably live close-ish I might see if you wanna put it under that little blackbox of yours :p

    Anyway, hopefully you'll have some more luck with those CPUs. Bit of a shame that there's such a thing as being too cold, esp. when it's above -100C.

    indeed, well i've got a good 146 comming with a good stepping, so hopefully doesnt have the cold syndrome.

    this black box is going to dinos22 in NSW. i've got another just like it which I use as my daily rig, & your welcome to come over for a benching session :)

    Im in Boronia 3155... 3150 is that Knox?

    couldn't you simply choose an alternative gas that has doesn't quite go as low in temperature at a given pressure, but still has high heat capacity so that the idle temperature isn't too low for the cold bugged a64s, but still decent performance for high clockage?

    absolutely.

    all you'll need is your Hvac cert :lol:

    so stuck with R290/R22 for the moment.
