Around, yeah.
Bit more with the full load of features I'd like to build into it.
Something about making the best god damn 3 stager in the USA comes back to my mind.

I thought u already did that with sdumper's

NoL · #13 07-06-2009

That's why this has to be better

I tend to hit a similar temperature though, but with better adjustment.

Don't tell me your making another Cascade on a Red Harbor Freight Cart

Or if this is the Mystery Man Cascade

NoL · #15 07-06-2009

Oh come on Buckeye. We all know I'm more talented then that

I'm MIG welding up a frame actually. Starting on it tonight,

Second heat exchanger rolled, CPEV's tested played. Nice and up front. They will be "separately" insulated in their own little sealed box.

Now thats sexy. And under 3 inches tall.

Nice work NoL, so your shooting for temps around -130 but with better load handling?

Buckeye · #18 07-07-2009

I would suspect after reading about your other 3 stage and the amonut of load that one could hold it would be some where in the range of -130c unloaded and below -100c fully loaded.

I don't remember what loads were used in that past 3 stager tho.

I would like to see a load handling ability of 300watts or more to be able to handle the high heat loads of Core I7 chips.

From my tests with my 920 D0 and LN2 I was able to take my chip to -130c and was still able to boot at that with a 5.3ghz over clock and vcore of 1.575.

How ever the sweet spot for this chip was in the range of -90c to -110c and did not find a real use of going lower for high OC's.

How ever with other chips this might be different.

Also AMD chips would love the extra cold and lower temps are better with them.

My thoughts on single or multi stage units is to go for max load temps and generally try for higher load handling ability as you never really know what chips you will put this on later.

From what I understand about these units is a low unloaded temp is not allways the best for handling loads. Better tuning of units will result in better load handling vs lower unloaded temps.

That stack is looking very nice tho NOL, good work !

Thanks for the clarification buckeye

Im no phase expert (I prefer LN2) I just remembered seeing sdumpers cascade at -130 coldbugging everything it touched lol.

I would eventually like to get a nice 2 stager but costs are very prohibitive for me. I got a wife n kids (hungry kids!) to feed.

(thats a pile of kids to feed)

Yeah I read that also about cold bugs. Different chips do different things, my 920 can boot at -130c under LN2 but some others do not have that luck.

I don't remember if that first 3 stager had a hot gas bypass on it. I think those are really needed for these things.

On mine if I start getting CB's with other chips I have to shut down the 2nd stage and wait until pressure has equalized on the 2nd stage before firing it back up. Usually what will happen after I shut it down is temps will slowly start getting warmer and about the time pressure has equalized I am good to go to fire it back up again.

Before I do fire it back up I start the compuer so I am in windows before I reach max temps. It's a pain to do tho. but workable.
