im using sketch up, its not teh point of as much airflow as possible, and  there wont be sidepanels.  so mostly wat im doing is jsut having a fan piointed at any heat generating part, and the fan on top are for cooling the pipework...

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

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?

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..

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..

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

ain't worth the effort....my rams are very cool even at 2.4v. With my cascade on my CPU....the area around it is also cold. My NB temps is only 33c with the NB volts to the max.
