Missed ordering the Optimus block on release day, ended up ordering an EK block from Titanrig. Optimus had posted that they "would be opening up orders in a few days" and then released it the very next day when I didn't check on it and they never emailed. oh well. EK block has been working amazingly, so likely will cancel my optimus block.
Got all the tubes bent up, leak tested, spent a couple days getting the air out of the 2nd loop. you can see in one picture how cloudy it was I first got it going. Core/mem runs between 10-15C delta to water temp, loop keeping water temps under 30C after long gaming sessions.
pads and KPX
Size comparison to original cooler
Tubes all in place
Back compartment of case. Not fully cable managed yet, will finish that up soon once I completely trust the loop
Lit up after install. So much air in the water, extra cloudy. Has since cleared up nicely with just a few bubbles on the glass that are slowly going away
