Ok so just set my water cooling up and i'm a bit disappointed. My temps are not great. Here is a brief summary of my kit:-

1x 280MM RAD
1x 200mm RAD
1200l p/hour pump (D5 with ek top)

Cooling:-

i7 ivy @4.5ghz
2x GTX670 (stock)

CPU temps under load are the same if not slightly worse than my air setup. 75C - 80C

Not sure about GPU's yet as I'm still getting this thing setup... that's not right surely is it?

what voltage are you running the Ivy on?
unfortunately, due to the way Intel decided to mount the heat spreader, it is quite a common problem that they run hot and no amount of cooling seems to really help much

the only common solution is to delid the CPU and direct mount to the chip, I've seen reports of 10-20C drops in temp by doing this
 
I have similar setup (240mm and 200mm with D5 pump) my 680 idles at 23c and my cpu (2500k) which would run cooler then ivy anyway, it's at anywhere between 55-65c on load. I would say something isn't right as your card idling so high. I guess your are using a Phobya 200mm which is the same as I have I thinks it's pretty crap to be honest, didn't see much drop adding it in my loop.

You done something wrong. Double check the tubing, make sure inlets and outlets are the right way around etc. What do you mean still setting up? The loop should be completed before turning the pc on, have you put the coolant in yet? :D

Wow 60C on idle. Have you removed all the air out the loop because it sounds like the fluid is not circulating properly

+1 tilt the case about, what l tend to do now is fill the loop as much as possible before starting her up. It's a lot easier to get the air out and save's time.
 
As said make sure there is no air in the loop, radiators like to hide nice bubbles so tilting it helps there.

The Idle temp on the 670s is way to warm for water. Have you tried running the pump at faster/slower speeds?

Also are you pumping into the res, if so that's not going to work too well.
 
Yeah sounds like ya have lots of air in the system maybe, it gets stuck in the rads and the blocks, takes lots of tilting and patience to get it all out. If ya have good flow and ya have all the air out then ya need to check ya have good contact, its hard to get bad contact with the GPUs though, its say its more likely to be air in the blocks and rad.
 
What fans are you running?

The difference between decent radiator fans and crappy ones are HUGE.

Do your rads, tubing and reservoir feel warm to the touch and roughly the same temperature?
 
Hi all, thanks for the responses and helpful suggestions. I do tend to agree about the air in the system theory. I can hear it clicking/making noise around the system. I've done some tilting of the system and idle temps on the gpu are down to 40C. The fluid still seems very cool in the tubing. I'm not at home at the moment so can't check what the rads feel like.

I'm actually using the same components (exactly except for pump) as this build by singularity water cooling. YouTube link here: http://youtu.be/OGtZiPQ8z8w

I've dropped over a grand into this so I'm a bit gutted to say the least. How full does my res need to be? It's only about half full currently, also I think I may have used the 1/4 inch thread screw top at the top of res elsewhere in my system so maybe that's causing air to get in?

Any advice very much appreciated.
 
40c idle seems much better, any clinking noise is a sign of air I found. Get it bled correctly even if you dont feel happy tipping stuff a lot of air will come out in time, keep an eye on your res though it will drop

40 is still too high for 670's, they should idle very cool.

Get us a picture of your loop if possible to make sure the tubing is connected up properly

Do you have fans on the radiators?
 
Hi again, as long as the res is about a third full its ok, tilt the case again but make sure the pump is under load run something like Prime. With the pump being flat out it force's the water round the loop forcing the air out much easier. Just keep a eye on your res water level, if you think there is air still trapped > clicking/making noise around the system

Check to see if you have the easiest route for the water to flow round the loop.
 
Hey, please see pics below. Just to add a further observation, when I switched it on for the first time it did seem to struggle pumping the fluid all the way around. It didn't shoot round straight away. There are quite a few different types of fittings but I don't see why it shouldn't flow. From the pics below does it seem setup ok? There are fans on the rads yes. Also managed to snap the solder off one of the led's for the blocks hence why no light on the second gpu. Will fix that at a later date. Thanks.









 
Not again D:

So many people make this mistake... you have the gpu's connected up wrong. The connector needs to be moved to the right then I'm sure your temps will be fine :)
