Ok,
I got the GPU block on last night after some faffing about and my first tube is bent!
Removal of the heatsink one from the Zotac was easy enough, however putting the new one on was a bit of a pain. I did notice that there was no TIM ona chunk of the chip as it came out of the factory. So Interested to see what this change might do for temps and clocks. I was able to hit about 1460 before IIRC.
First up I'd put far too much TIM on the block so redid it, next up I had secured the 4 main screws down to hold the block tight to the GPU as well as the one screw holding the block to the back plane. The problem was for some reason the backplane hole is slightly out of alignment with all the other holes, so with this in I couldn't secure down anything else. So I've gone without that screw so that the backplane and so on can be connected properly.
It's back in the rig now and running fine since at idle with no cooling its happy at 50c.
I also bent my first pipe which connects my 4 way block to my drain ball valve. Its not a perfect bend and there are some scratches on it from the fittings, but it's tiny, in the base of the case and may well end up being redone anyway.
Bending it I found easy enough, however getting the damned thing into the fittings required quite a deal of force. These EK HDC fittings are incredibly tight even without the compression seal. I just hope I can make all the other connections while its all in place, as this one was hard with it in my hand!
Rads are also emptied and washed through 3 times with a PH measure taken after the last. The 1st stage came out a little cloudy but not hugely with a couple of teeny tiny particle in from the rads. So it looks like EK get another point there.
I'll be bending more later to join the front rad, pump and GPU up.
Anyway. More pics.
