My system;

x58 3x SLI Hydro package, i7 975, 2x295 - Both cards plus the mobo is being watercooled by koolance 980bk and CPU is running a V10. All stock, no OC'n as of yet.

My cards are getting a little hotter than I expected, running at 2560x1600 resolution while gaming, temps getting around 60, is that normal due to such a high resolution?

Also, should I add a 9800 ultra? I don't quite understand what the use of it, could someone explain to me or give me a link in which I can read for myself? Sorry, just getting into the "game", and I have been reading a lot of the stuff on the forums, but apparently not enough.

Is my pump/resevoir enough? Should I get another means of pumping the coolant through the veins of the computer?

Once all of that is done; anyone know of a nice safe OC setting that one can do with the 295's?

Thanks a ton in advance, hopefully one day I can repay the wisdom I am sure I will receive!

60 is fine loaded for those cards. You are asking one loop to cool 4 GPUs plus the north (and south?) bridge. I'm pretty ignorant when it comes to watercooling but I had thought that putting chipsets in the same loop as GPU or CPU tended to restrict the flow a good bit? Isn't the 980BK one of those compact drive bay setups? What kinda radiator you have hooked up?

No such thing as a 9800 Ultra. Are you talking about adding an extra card for Physx?

Yeah, for the Physx.

This is the case I have http://www.frozencpu.com/products/12...tml?tl=g1c2s35

And yes, that's a drive bay setup. I was told that they would suffice.

This is your weak link for the water cooling, especially when you decide to overclock. You spent a fortune in quality parts and have a dinky drive bay pump running the system. Get yourself a quality aquarium pump like an Eheim and you will be much better off. Just google eheim pumps and you will find a range of resellers.

Just for an idea of the difference... Your drive bay pump pushes 111 gallons per hour. An Eheim 1250 pushes 317 gph and an Eheim 1262 pushes 900 gph! (Though the later is way overkill)

I don't know anything about your physx question or overclocking those cards in specific, so I can't help with those questions.

So, you would recommend getting say Eheim pump to push the liquid? If so, how would that set up work? Get the pump, then get a reservoir?

As for the physx, I am just not sure how that works. If it makes a huge difference and such.

Yes. I personally don't bother building with reservoirs since they offer no additional cooling. The radiator does the cooling, having hot water sit there doesn't do any good. That said, it does no harm to have a reservoir and it definitely makes the filling and bleeding MUCH easier. Either way you want to go about it you will see significant improvements by increasing the flow rate 3 fold.

I see it now, will check it out. Now can I have both of them? Say keep the Koolance Drive Bay pump, and add the Eheim at the bottom of the case?

I wouldn't bother w/ an additional Physx card w/ that many GPUs already in your system. All it will do is add more heat. You should have plenty of left-over power to run Physx on the 4 GPUs you already have. Plus, there is only a handful of games that actually make good use of an additional card for Physx, but only when you just have 1 GPU to start with.

I'm not sure having two pumps (mismatched at that) in a loop does much for performance. You'll probably still want to hang on to it though, in case you decide to add another radiator and split up the loop (typically putting CPU/chipset on one, both graphics on the other).
