if you used 2 rads would you then get away with using slower moving fans and have even better temps?
what is it your running now then, or will be once you've finished if theres such a thing lol

More bad news 
I've managed to knacker the motherboard for the new gaming rig. Got it all together and fired her up but it wouldn't boot. Kept getting error code 55 on the MB (Memory not installed). Tried various memory combinations to no avail so I did a bit of Googling and the general consensus was that it was caused by bent pins on the CPU socket. Took it all apart and got the magnifying glass out and sure enough, there were bent pins. I straightened them up as best I could and fired it up again. I managed to get it to boot but only 2 RAM slots were available and they were next to each other and would only work in single channel. It would also only detect one of the 690s and the CPU was overheating badly.
I can't afford to replace it just now so it's gone on the back burner. I don't want to be without a gaming rig and I don't want the 690s sitting idle so I've switched the SR-2 back to windows and bunged them in there. All is working well except that I can't get any OC on the 690s. They work perfectly fine at stock but as soon as I try any sort of OC on them, the PC crashes with a blue screen. At least it's working.
I'll be keeping the current setup for the foreseeable future as I'm not spending any more money on it until I've got my credit cards cleared - which will take a while.
Between the SR-2 gaming rig with the 2 690s and the old gaming rig with the 2 670s still surviving, HFM is estimating 538,000 PPD. That'll have to do for now - at least it'll hold off ozaudio

That sucks Stan but you don't want to be spending money on cc interest that could be put to better use.
Being able to keep ozaudio under your boot has got to be a silver lining

Bit of an update. I've decided to keep the SR-2 with the 690s as my gaming rig so I'm going to make it permanent. Up until now, I was cooling the 690s with a radiator outside the case on a separate loop. I'm now going to put everything on a single loop and mount a second radiator in the front of the case. I've got it all stripped down but I've decided to make a few slight alterations so I've ordered a few bits and pieces to make a proper job of it. I should hopefully be finished in a few days, depending on deliveries but, in the meantime, my output will be down considerably. I'll post up some pics when I get her finished.

Cool at least thngs are still working I'll share pics of mine when my new rad turns up and I can water cool the third card.

I know thread is a bit old... but that is quite a run of bad luck I hope you get some good luck coming your way soon.

Got it mostly together and the loop built. Just leak testing now and waiting for all the air to get out of the loop. I'm using one of those bay res/pump combos. Excellent piece of kit but badly designed - the inlet for the res shoots the water (and any air bubbles) straight at the pump inlet meaning most of the air bubbles keep getting recirculated and it takes ages to get all the air out of the loop 
Once I'm happy with the loop, I just have to tidy up the cabling at the back and then I can start overclocking and testing.
I think I may have worked out why I couldn't get the 690s to overclock before (mentioned above). The PCI-E cables for the NEX1500 PSU have 2 plugs on each one. I was using one cable to power each card. When I checked the specifications for the PSU, the 12V rails are rated at 20A (240W) and have a trip limit of 25A (300W). A 690 at stock will draw 300W at full tilt and more if you increase the power limit and overclock them. I suspect I was overloading the 12V rails and tripping the PSU. I have set it up to use 2 separate cables for each 690 now - hopefully that will allow me to get a decent OC on them.

Got her built back up and now setting up for gaming and Folding. Finished overclocking and now testing for stability - so far so good, all stable and temps at perfectly acceptable maximums. running Prime95 small FFTs and Unigine heaven at the same time. CPU temp maxing out at about 46C and CPUs at about 67C. Got a pretty decent OC on the CPUs - running at 4.0GHz (50% OC). 690s are a huge disappointment though. Best stable OC is +45 on GPU, that's 957MHz with a boost of 1084MHz
Never mind, here are some pics:
Side on - check out the neat GPU cabling
Tubing is XSPC 13/19mm and fittings are all monsoon. The monsoon fittings look really good but are a bit of a pain; you need to tighten as many as you can before installing as it's really difficult getting into tight spots with the tightening tool.
Top rad - Alphacool NexXxoS UT60 Full Copper 360mm with 1450 rpm Gentle Typhoons in push pull configuration. You can just about get a fag paper between the bottom fans and the RAM - I've tried it
Front rad from the side - EK Coolstream XTX240 with the same fan configuration as the top rad.
CPUs - 2X X5650 Xeons with Koolance waterblocks. Oc'd to 4.0GHz
GPUs - 2X GTX 690s in quad SLI with EK waterblocks. Paltry OC of 957 (1084) gpu and 6480 mem.
Cabling at the back - about as neat as I can make it. The SSD isn't there now. I've come up with another plan for that and will update when all is complete.
Front on. 2X Akasa fan controllers, cheapo DVD-RW and XSPC bay-res/pump combo with a D5 pump. Also showing front view of 240 rad.
With the side panel on. I hate the side panel, it's fugly. Might consider modding it in the future.
That's all for now. As I said, I'm currently setting up and benching, will update again when everything is finished. I also need to solder the power switch. I managed to pull one of the wires off when I was building it (clumsy sod). I've currently got the reset switch wired up as the power switch until I can find someone with a soldering iron I can borrow (not buying one to fix one switch as it will probably never get used again).

Been running for a couple of days now and all appears well. Took a screen clip. Happy with temps and ppd is good. With the 7810 WUS I'm getting just now, I'm getting about 580,000 between this and the other rig in the living room (~530,000 with 8900 WUs) https://dl.dropboxusercontent.com/u/9786118/HFM/summary.html.
I'll catch my Bigstan account in a couple of days. Not sure what I'll do after that. Bit bored with Folding now but I still want to do something. I'm thinking I might leave the other rig on Folding and do something else with the SR-2. Any suggestions for other projects which would make use of dual Xeons and 4 GPUs? I'd prefer projects that offer some tangible benefit to humanity rather than stuff like SETI.

I wouldn't be able to do that without buying moar hardwarez anyway.
I've left the other rig on folding - currently around 170k PPD (still enough to keep me in top 5 for PPD in the team). Now running GPUgrid and Rosetta on the SR-2. Had a bit of bother last night, the Nvidia drivers kept crashing and the PC was freezing. I remembered that the R331 drivers didn't play nice with Folding so I rolled them back again to 327.23 not long ago and all appears to be well. Looks like the R331 drivers on the 690 are not suitable for DC projects
No idea what my RAC will be, will have to wait a bit.
Are you on a one man crusade for world (or at least team) domination in GPU Grid
Surprising how many cobblestones you can amass with a couple of 690s in GPUgrid. I've been getting over a million a day since I started
.......... aaaand, it's all gone horribly wrong again. I was happy with the way things were going so I decided to replace the soldered switch and close the case up. Did that and tried a bit of overclocking on the CPUs (I'd had them on stock while I was trying out the BOINC projects). I couldn't get a stable OC at the same settings as before so tried different settings. Nothing worked so I set it back to stock and it's blue screening even at stock now 
I've unplugged the soldered switch again, in case it was shorting or something but no change. I've set memtest running and will leave it overnight. I've had enough for now and I'm busy tomorrow. I may get something done with it over the weekend If I can be bothered. To be honest, I've very nearly had it with this bloody thing

Well, I've narrowed it down to a windows update. A system restore stops the blue screens but, as soon as I reboot the PC, it re-installs itself and, if I shut down the PC with the 'shut down and install updates' button, it all goes Pete Tong again - even if I switch off automatic updates. If I had an earlier restore point, that might help but I don't. I need to find out which update it is and a way to stop it installing itself.
I'm off out in about an hour so I'll look into it when I get back.
