Right. So I have leak checked and it all seems fine. I read that the only way you'll know for sure if it's leak proof is when you turn it all on, since heat changes the nature of the water. Kind of freaked me out. Stress tested the GPUs and there was a faint leak on the 45 degree compression fitting leading from the bottom GPU to the QDC. I had a look and it seems I was bending the comp fitting away slightly from its O ring. Swapped it out for a straight comp fitting and let the tubing do all the bending. Seems fine now.
Have added Mayhems to the distilled water, but didn't realise it doesn't come with biocide. Have ordered that, and should be arriving tomorrow. Am STILL waiting for the drive bays from Caselabs. They have been sitting in customs at Heathrow in London since the 6th of August. I know we are inefficient in the UK but that takes the biscuit. Maybe it's to do with the Olympics and stuff - I don't know. Still waiting anyhow.
So yeah, all seems ok. haven't overclocked the cards or the CPU yet. Am running small fft test in Prime and under 100 per cent load I am getting 42-43 degrees between all cores. I don't know if this is any good. Certainly better than my air cooled set up. Oh, and this thing is really quite - can't really beleive it. That in itself is worth all the money to me!
I'm guessnig that if it's leak proof now under load then I am OK to go ahead with upping voltages and gettnig this thing overclocked. Maybe I'll run the GPUs again under 100 per cent with EVGAs stress testing stuff.
Anyway, sorry to go on. Here are some pics.
