Oh yes. Sdumpers unloaded towards -150C. Coldbugged motherboards and RAM too ;)
The CPEV on all stages will allow a certian amount of dialing in of the temperature. Unloaded might be below -150C with the valve closed, but real useful tuning around -125C at i7 loads is a good goal. It will have a hot gas bypass as well for expressedly warm situations, and a controller on that to actually have it control a temperature automatically.

Now we're talking, nice :good: Git er dun!

-150c unloaded :eek:

I really like that -125c loaded Core I7 temp tho ;)
With a setup like that you really would not need LN2 for 90% of benching, except for newer AMD chips that it. But very useful for getting everything setup and tuned before going to LN2 :)

And for that you could still dial her down colder for lighter loads. Not much use past quick Pi and such, but still not bad ;) The mass I'm delivering in the evaporator should be interesting.
Let's just say it competes with many top end ln2 pots.

Though finding the condenser I want is starting to become harder and harder.
Might have to shell out some serious cash to someone in Euroland.

I dream of the day I have a cascade setup. :this:

They're pricey, but if you bench Ln2 on CPU only 20 times, you've paid more.

Not with the rates I pay for LN2 :D ($0.50/Liter)

So $25 for 50L.
$300 for a CPU pot.
$400 for a dewar.
How many runs to hit $1600? ;)
28?

I prolly have just about paid for my Cascade in teh amount of use i get out of it, almost everyday its running which I could not do with LN2. I save that for chips that can really use it and for GPU's when I run them.

To say nothing about ease of use. You can walk away and do others things when the MonstaCade is running and not have to worry about the pot running dry. Being able to take your time in tweaking is also a big plus.

It has not taken away my need for LN2 to tho, just made things much easyer.

How ever, colder is better :)
