advice needed on SS/cascade in a MM case - Overclock.net

-|HAZE|- · 05-16-09

i was thinking of getting a mountainmods case and putting my bench rig in it.

on the other side i wanted to build a STRONG SS or a cascade.

i'll be cooling an i7 around 4.5ghz

is this possible?

how large of compressor would keeping the i7 cool require?

it would be possible to fit a SS in there. there are a number of factors to consider when building a SS like type of refrigerant, size of condenser and the length and diameter of the cap tube not just the size of the compressor, the best to ask would be XS

i have asked on XS numerous times and i never get a reply.

I added some for info to my last post, if you are not getting a reply just check out the stickies and other plls threads and you should should have some answers, also im not a pro but i have a pretty good understanding of how SS works so i can help you with some of the points in SS

well i would definitely be building a TXV system instead of a cap tube system. i thought of building a 2 stage cascade in it to better hold the load of the i7.

i got the idea of a cascade from a build on XS... http://www.xtremesystems.org/forums/...=218389&page=3

Been there done that.
Cascade will take up the whole case, unless you want something rather tiny, then its taking up the entire half and has too much heat. A proper large cascade will take up the whole cube. And again, you won't want to pay that for 24/7.
Single stage is easy, but the heat can be a problem. So you have to do a few air circulation changes and divide the system off.

its for benching only so thats not a problem. will only be run a few hours a week tops.

how about a single 5k-6.5k btu rotary? would that hold the i7 down? im not looking for super cold.... just -30c or so under load if thats not too much to ask for.

im all for a SS but it will be a TXV setup, not captube.

i'll be using a evap from teyber on XS.

From what I see, better be a big evap, very large for the load.
-30C is decently cold for that size rotary on that load. Would be a stretch. If it's just for benching why such a nice case. TXV won't work well with a evaporator like we use, vary's too quickly.

i got the MM on review... it was free.

so you are saying a larger compressor? like 10k? i have one of them as well.

NoL · 05-16-09

Larger doesn't mean better. It's just straight up unhealthy to run any compressor in vacuum. Those temps require a vacuum. And ten degrees really won't help you much as a healthy evap. And I still don't believe we are using "healthy" evaps. But the real cost of a 2 to 2.5" diameter evap with a long pathway is rather up there.
