frozen cascade

[kayl]

basically finished the tunning on the system now, Cascade did -98c at 312w and -101 with 270w.
time to put side covers on and get ready for a bench
cold bug switch on drops down to around -96c.

What's your static like with filter and such post hx?

[ThaLoveDocta]

I've said it before, and I'll say it again,

You do fantastic work kayl.

Static pressure is only 150psi, exactly the same as the last cascade

I've said it before, and I'll say it again,

thanxs ThaLoveDocta.

For the first hour cascade idles around -110c and load -106c after 4hrs it was -104c load and -106c idle with 5.5ghz 1.95vcore on my E8500.









And the bench results

Looking great Kayl, of all the builders i think you're the only one that always tests stuff on a real PC platform and show some results, not just on load testers! Superb!

Use 80cms 0,8mm cap tube to exp tank.

Place the exp tank higher than the compressor.

So this would mean about 50cm 0.7mm (TC-28) cap tube? Is it passable?

Down Under = On Top!!

Those 8500 are BAD

thanxs tiborrr, load tester cant really simulate a cpu, its good for ensuring a system can hold a certain load but some times you tune for too high load or not enough, only way to really know is with a cpu

1366 mount plates, they should be ready in a few weeks

[sjg0]

Sorry if this has already been asked, but will current evaps need to be modified/replaced to become compatible with Nehalem? I think the 1366 chips are a tad bigger than the LGA sockets.

[[XC] gomeler]

Nope, the core itself hasn't grown larger than the evaps so you are fine. Hell, current Chilly1 evaps don't cover the entire IHS on LGA775

[tiborrr]

It's not needed anyway. Current evap heads are really large enough for LGA1366 chips, although bigger the head, the more evaporating surface it usualy have ;p

Great work Kayl, once again!

[kayl]

if it was water cooling ideally you would want a bigger evap, but for phase change its not such an issue.
It will be like going back to the old 50mm AMD cpus

The look of your units always makes them stand out. I had no idea that even LN2 would allow for 1.95v core a 45nm! very impressive results.

Nice and low temp rise when loaded BTW

thanxs eligray. most vcore i ever run was 2.15v on ln2 QX9650

new plates are ready

Where's it going off to? Someone in the AU?

[before]

Looking very good mate.

[HawaiianSupermn]

Can you put one in a canoe and send it my way bro? Very nice work

[Stelios]

Kayl , where exactly do you measure the evap temp ?????

[kayl]

thanxs guys

Where's it going off to? Someone in the AU?

from one side of aus to the other, Melbourne
dont think i would want to send one outside Australia

Kayl , where exactly do you measure the evap temp ?????

i measure mine close to the base of the evaporator. I file the side of the evap and dab the k-type probe in thermo paste rub some onto the evap and then tape her tight.

Evap to core temps.

What's your thinking on the delta here?

Say the evap temp is -50... do you account for a diff of 5C? 10C?
or are you assuming the core's are almost the same temp as the evap?

Thanks ! Your temps are really nice !

What's the lowest with a dual core E8500 or E8600 and wprime 1024M (1.85Vcore or more ) ???

And one more ... ... What are the running pressures of the 2nd stage ??? Idle/load ... both low and high .

It coming to me
Gonna strap it up to the 790i digital i got from ya.
Post some results soon

didnt run prime1024 sorry, i know with a quad core around the 84% things get real hot.
E8500 with 1.85v warmest i seen load was -104c i think after 4 hrs benching.
idle the second stage is around 200psi, after 4 hrs benching around 220psi.
low side pressure would be around 10hg idle and a few hg load
with 310w load it was a few psi load

firstage was around 4psi low and not too sure high stage pressure, under 200psi i suspect.

i dont really take much notice of die temps as it changes from motherboard to motherboard and cpu to cpu.
maybe first mount on a a cpu, i let the run pc at stock and then boot into bios and watch die temps compared to evap temps, normally a few c difference between the 2, wait till it hits 60c then shut cooler off. if i have a bad mount temps will be alot hotter and pc normally crashed before dies reach 60c. then i start the cooler and bench.


also gigabyte mobos only read down to around -8x c and no lower, at load die temps stay the same, ie colder than -8x c

cant wait to see the 790 under the cold

Very useful info . Thanks for the details .

The reason i'm asking all these questions is cause i made a new cascade with two rotary compressors ( 30cc each one ) . I don't have very good evap temps (-107c idle , -96c with 230watt cartridge) cause the vacuum is very high (about 15hg under load) . I'm using 1.7m 0.078 ... but i think i have to try something like 1.5m (or 3m 0.091) .

Thank you Kayl again !!

I hope you have a QX9650, that board is stupid strong with a QX
