yes this was designed for version 1.337
and if you had read you would know that the whole point of making this was because no one else on my server had
another minor point of this was to show that ice is still very underpowered as a cooling device
also ive been doing some math on it myself 25% loss is on a low level ice casuc the percent loss actually gets lower the higher your efficiency rating is my current one is about 23% but my expanded design if i ever make it should only have about a 20% loss
also i would like to note that i have since posting this cut 1/6 of the compressors out from a trick i found by hooking up 3 snowball compressors to 2 ice compressors i also shrunk the space needed by scrunching all the machines together the finished on server design should be much smaller than this one
