Finally it wins. Those fittings, connectors etc are the biggest cost to make a nice looking custom loops.

Found this here OCN Water Cooling Gallery
I fully agree with Ken and this is actually the way i decided to follow and will use 2 mcp655 in series>mora 9*140 pro>cpu370>mips northbridge block>VidAR699>reservoir (any ideas about this loop are more than welcome!!!)

I am afraid though, that the solution shown in the picture attached by ken is not that much of a safe solution, since the BIG mora gets very heavy with all the water included, changing a lot, the center of gravity of the entire case!

However this is what I had in mind (beware hastly done mspaint work)

Urkling, I really wish we could use mora like in your graph... but i believe that mora works as a single radiator and not as 3 separate ones. If it was able to be used like 3 separate radiators, then it should also have 180 degrees external connectors in case you wanted to use it as a single!

Couldn't believe to make that mistake, but

Edit:

This diagram will show exactly where to put the 0.5mm pads better than the diagram came with the blocks.
Guys, Ken and catcherintherye, did you fix the problem?

Having read Levesque's comments/experience about the koolance waterblock i am about to order it and got really surprised by your posts...

Still not solved. Here's the response I got from Koolance:

"There are chips on the back, but you should be using the stock back plate (as our VID-AR699 manual describes). You are showing GPU temps of 44-48ºC under load, which is fine. Vregs on air go over 100ºC, so I wouldn't worry about 71-87º unless there were visual artifacts or card lockups. It sounds like pad contact could be better in the VReg area(s), but it can be a lot of work to dismount and check that (and you run the risk of worsening GPU contact).

This guy's using another company's 6990 block, but gets 94-97ºC on Vreg under load (and 56-62 on GPUs):

I would know about the temps after I connect all the tubings. There shouldn't be any problem with the temps if all pads are making good contact.

Mine has been sitting like in the picture for weeks. Undecided if I should scrap all the aluminum radiators I am now using (still have many of them new in box) or go with 2 MO-RA 9x140 Pro Extreme. Yes, I know but I like overkill

I wouldn't worry about the weight and you are using full tower case, though the MO-RA Pro 9x140 + coolant weigh around 15 lbs. The COG should not change a lot to make it tips over, unless it is extended to 4 - 6 inches away from case panel. There is an option to get the stand for it that set you back around 40 bucks.

2 mcp655 in series>mora 9*140 pro>cpu370>mips northbridge block>VidAR699>reservoir <----- should be fine for 24/7. With 2 MCP655 in serial, you can add in the rads you have now anywhere in the loops later on.

You are correct, the MO-RA is a single large radiator. The additional threads are for filling, bleeding, drain, temperature probe, pressure sensor etc.

Ok, I understand koolance's reply, BUT still i dont really like the fact of a card being heated unevenly along its length, something that doesnt happen on air.

I dont know if putting the EK Backplate would do better job than the original backplate?!

Any opinions on that - koolance waterblock with ek backplate?

The EK backplates are more for the aesthetics and not to dissipate heat better than the stock one. well, maybe a little better if it is thicker and with better thermal conductive metals.

Unfortunately i dont have any more rads to add and also will get the stands and covers of mora to use it as a standalone. The reasons i put 2 pumps in series is: redudancy, better flow rates, the mora will be placed approx 1.5 meters below the PC/desk (perhaps - i am not sure - this influences the flow as well?)

Well, it all depends what your objectives are and want to achieve such as what delta temp, overclock limit, or just to get rid off the noise etc. But for 24/7 one MO-RA 9x140 out side the case, I would say one is sufficient and it gets a lot fresh air positioned outside the case compared to rads in the case.

I, personally always go with 2 loops, one for CPU + mobo + memory and one for GPUs. Reason is, easier for me to control the temps when I get into OC though I have everything with QDCs to have the flexibility to make it into a single loop, to add in more pumps, rads or to take them out, for draining, connect pressure valve easily using Quick Disconnect No Spill.

AFAIK, there is no memory temp sensor for 6990 or any previous models. Should not be worried about the memory temps as to what backplate to use as long as all the thermal pads are all in place and making good contact, backplate-thermal pad-memory. The un-even temps on core are normally due to the way we apply the TIM. If you are taking the time to do it properly and evenly on the GPU Cores, the temps should not go over 2-4c across the board. Of course the idle core will show lower temps.
