Howdy, So I have a Intel socket 775 test bench setup ATM. I had originally planned to just use a water loop to bench with, then I thought why not go sub zero After asking a few questions and checking my funds I ruled out going Ln2 or DICE. After seeing THIS PICTURE and adding things up, I will walk away spending only approx $200AUD So some back ground, I am no stranger to cooling water using refrigeration, here is what I work with on a daily basis But I am going to be working with something a little smaller The large chillers above are approx. 1,500 Kw of cooling each, there is three. The small one is; 850 w, so not even 1 Kw. After just a few minutes, 30 minutes or so, I have managed to get most of the controls removed. So my future plans are to do a little surgery on it. I plan to remove the reversing valve ( the part that allows it to change to heating). Doing this will allow me to neaten up the look. I think placing the esky (ice box) on that top platform, after removing the fan, with the bottom compartment covered by either timber or some polystyrene. This will be mainly for noise isolation. The esky I have planned on is; As for a coolant in the esky, I plan to use Valvoline Zerex DEX-COOL which is good for -37 Celsius, but I doubt I will get that low. The loop going to the CPU, and maybe GPU (later), will consist of my beastly Koolance PMP-500, Alphacool NexXxoS XP3 Light block, a T piece res. which will be filled with Mayhems XT-1 (which should not freeze).
