well there is teh desuper heater coil , on both set ups.. that l go just above the compressor... and to mover the hot air out thru the back.. as teh compressors get hot.. teh hot air will be rising.. so the piepwork will sweat... the cold ones at least.. the fan prevents that also...

yo andre bro....good to see you here. anyway the 12cm condenser will do for now as that is for daily usage....so basically the compressor will not be running all together at any one time. its either cascade or SS.

As for the cascade....r22 will gonna be used for low stages. I'll try to get a better refrigerant for the 2nd stage. Anything better then r410a requires an oil separator. There's still some spacing left...so adding an oil sep shouldn't pose any issues.

Hmmmmm....looks like I'm gonna be making friends with MOX soon if I wanna outmatch you guys. RM80/= a tank of LN2 sounds tempting. Now for a rod of copper to mill

haha bro u forgot ur dewwar.. or u already haave a dewar?

though ln2 is much cooler than cascade....but just calculate the cost. RM80 per tank oni last for a while. Cascade last forever!!!....yeh!!!

it's not a matter of last long or doesn't last long. After all, show me one OC'ed system on cascade that lasted very long. Hardly a few do due to the electrical stresses you put on it. In fact a few stopped using phase change (bulkhy used to make em') since the maintenance was an arse anyway

well...for one, i game on my cascade. 3 - 4 hrs daily. Maintanence???.....no worries dude. I dun see any maintanence needed. Its not like home A/C unit which needs servicing and refrigerant top-up. Anyway, FYI bulkhy will be back. We had some discussion on building his cascade.

well imo a well made and organized cascade wont need much maintainence . i dont get wat u mean by electrical stress.. u mean electric bills?

the stress on the proc , mobo, RAM bla bla bla. Heck even fugger doesn't run his triple cascade often (Not to mention the fact it'll kill his AC outlet)

Maybe it's time I got serious again with OC'ing. Maybe....see how 1st. I can barely fund my PC's maintenance now

ahh those issues.. of course u dont run ur cascade rig t4.7 lah... u under ln2 also u run 24.7 meh ? lolz.. but the stess is a known thing.. when oc u knw the risks involved... no offense though

neway thats y i have a daily use Single Stage on this setup .. so its esay to move an swithc..

precisely the point. LN2 when u kira ur costing just as low to use. Just that you have to be more careful unless u want extreme frostbite on ur body laaaa. LOL

well depends lah.. im a heavy bencher.. almost everyday .. and with the cascade easily will hit 10hrs aday...im, already clocking in about 9 to 8 hrs aday of testing with air ( waiting for uni is so boring) so using ln2 is too exp hence this project.. if ur a once a month bencher then its fine....

haha about ln2 giving u frostbite its actually not true...

did u kwn the safest way to handle ln2 is without gloves?

yeah its shocking but if u ask any chemist hell tell u that its true.. adn that if u stick ur hand for a second into a small pudle of ln2 , say in a small bowl , ur safe.. and it wont freeze, heck u can pour it on ur hand and it wont freeze..
this phenomenon is due to the fact that ln2 evaporate teh second it touches anything hotter taht it self.. which is almost everything lolz ,
when it evaporates, it formes a layer of gas , and it floats on it.. unless its too heavy and gravity does it job and the gas can tsupport it, this is only for large amounts..

about the gloves, the reason being is that if u splash in on u, some of ln2 might spill into the glovess and into thefingers area. teh ln2 wil not be able to form the cuhion or gas be casue of the enclose space and it will freze ur hand. also wearing anything canvas shoes or shirts, it will soak up the ln2 and freze u so happy benching, hey bro if u have a DEWAR container , pls do gime a pm. might want to borrow it..

yeah I know that due to it's instant absorption of energy causing it to disperse into gas. It's when accidentally spill 3 litres of it then you might consider it something else. The container still doing the drawings since need to finalise few details then do a CNC coding because the tube will be counter sunk into the base plate so precision is a must for me. I haven't decided to do the brazing on my own or not

What's more budget and materials sourcing an issue. LN2 by itself is cheap. It's getting the tank for it an issue. I haven't asked MOX for prices yet. What's more, need someone to point to me a copper rod supplier.

hey dude if u found a source of copper rod do let me know...been looking for it crazily @_@

i have plenty of that here....thanks anyway.

what are the dimensions and in what lengths?

the evap head that will go into this cascade and SS..

finalised the compressors that i will be using with extremeocer. will be three 1 hp matsushita electronics compressors.. adn some home made condensors...






neway extremeocer did some tests...
to test the evaps, bench rig.


done with r22 low side and r410a on the high side... this should be the gases i wil be using in my cascade when its done...



teh cascade



, got -75 C unloaded. and -63 C loaded. Using a e6600 , clocked at 4.3 @1.65 v.
temps were measured from the suction line. didn't get to measure from teh evap , ,,

Here's a little update on my Cascade


Before - Captube running thru the middle of suction line


After - captube connected from the Y-joint to the evap - neater eh




Thats the DIY condenser




Evap starting to freeze


After 1 minute....Ice Kacang anyone?


Now that's extreme gaming at 4.3Ghz

Man...this is awesome... doesnt the ice damage the board or chip?
