Well I think i've recovered from vacation and gotten back, mostly, to my normal routine, that is if I knew what was normal in the first place.
Good news is the computers ran fine while I was gone, although since this was my first vacatio naway since bulding these, i throttled the gpus back from 3 to 1 on each. I was a little nervous about leaving them on full power, ie heat output, and not being around to monitor them. The controller unit dos have limits on each temperature sensor and is suppose to shut down the mobo if exceeded, if i have them set correctly that is.
So today i added liquid to each ??? I have the level marked on each reservoir, and over the last month it has gone down some again in both units, yet I cann't find any leaks or a pool of blue goo on the floor anywhere. I guess since these run rather hot for long periods and it was the same amount about in each system some of it is boiling off ?
Anyhoo back on track, today I spent revising my notes on parts used in each of the two running systems and parts left over. Soon I'll have to redraw the other three systems and figure out what parts will be needed, compare those with what I have left so I can think about a reorder, and wait for a sale, then think about what gpu's I want to buy and waterblocks and look for those.
Let me recover some more and rebuild my energy to get back into building these.
When I can find more time I'll upload somewhere some of the photos I took, hoepfully these might help make some more sense of this.
