But he has 2 pumps so it may be enough but i would get a hi flow pump to go with it if i were him.

right been testing since my last post, ive got 3.6 stable but temps do rise up to 80
but then the reserators hold the heat and takes some times to get to those temps up and down! im happy with that and im not gonna try to enable intel speedstep so its only at 3.6 when i need it! obv il be running prime95 again to see if thats stable!

Sorry to resurrect this ancient thread.
I have a sinvgle reserator 1 V2 cooling a GTX 580 and an intel Core i7 950 3.06GHz
I just wanted to check that as a short term solution (until I figure out if I want to remove the pumps) I could get a used reserator 1 v2 on e bay and simply put it in series with the pump running as normal and the air hole on the first blocked up? That is what this thread sounds like.
What happenes if the first pump in the loop directly after the computer pumps harder than the 2nd pump surely the 2nd reserator then over fills and water starts coming out the vent hole?

Hiya, im currently running a pair of reserator's to cool my Xeon 1245V2 (i7 3770) and HD7950-B, the difference mine are both de-pumped and set in parallel not series, but I did have them in series before that and I have also run single res setups both off the standard pump and using aftermarket ones.
Here's the best thing to do as a simple solution while your deciding on weither or now to go aftermarket on pump and stuff.
1: Get the second one, unscrew the bottom off, then undo the screws for the clamp holding the pump in place and pull it up out of the hole, then put the screws and clamp back and cable tie or whatever the pump out of the way, this basically makes it a de-pumped res but without the work and has the option to easily reverse it at a later date.
2: while here you should add a couple of inches of hose to the return nozzel, this is because the hot water comes out here right next to where water is being taken out from, this will ensure the hot return water makes it clear of the current and rises to the top (people have seen improvements of up to 8 degrees from this "snorkel" mod.
3: Connect it up BEHIND the res with the pump in (it will NOT work the other way). So basically you want the water pumped out of the active res, through the system, then into the passive res, at which point physics will ensure the water levels between the two remain constant as water removed from the active res is replaced by water equalizing from the passive one.
That should do you for a short term solution. Here's my thread when I was going series then parallel: http://forums.overclockers.co.uk/showthread.php?t=18436903&highlight=reserator+username_ubersonic
Note the first res the water comes back too will get hotter than the second, this is to be expected.

Uber, you win an A for awesome!
The bottom is allegedly a bit of a bitch to remove did you have a lot of trouble?
I have done the snorkle mod thanks for the tip. I have skinny hands so managed to do this without removing the base.
At the moment I can run games with the rig stable but after a few hours the reserator tower is hot to the touch. I am ashamed to say I have not checked temps of the core and gfx card but I suspect they are toasty if the "cooling" water is hot!
What happens if you put the two reserators in parallel with a y connector joining them both before and after the reserators and leave both pumps running I wonder?
This should give you more pressure as you have two pumps pushing into the computer. What happeneds to the water going into the reserators? Presumably as you have water entering both towers at the same pressure the water level should stay the same in both?
That might solve the issue of the weak pump and my lack of overal cooling capacity at the same time and will mean no modding either reserator (other than snorkle). Plus it ahould also mean that the water in both reserators is the same temperature which should be more efficient.

On my blue res no, on my black one it pretty much took every ounce of strength I had (which isn't anything special tbh) it probably depends on how tight its done up and how long ago that was.
How hot is hot? Mine get warm to the touch on top but that's expected as they are radiators, if they were always cold it would be a sign the cooling power greatly exceeds the heat load on it. But im guessing quite hot as I have twice the reserators and a lower TDP GPU.
This may sound crazy but if your res is next to your PC and it has a side case fan you can remove the side panel (keeping the fan plugged in ofc) and put it against the res so its blowing air onto it which will really boost the cooling, I did this when I only had one res and it kept temps fine, its not very practical but useful for a short term solution. It works because the res due to its large size gives serious radiation area and liquid storage and is on par if not better than a 120 rad with an active fan, but a res with an active fan is a pretty beasty concept.
Im not sure, I would think the fluid returning should split evenly or as good too, it could be an issue however if one of the pumps is pumping more than the other but I don't really know.
TBH the weak pump thing is grossly over exaggerated, hence why I advised you to use one if you were running them in series, set to max speed (theres a slider on the pump itself that goes between a + and a -) they will do 300LPH which isn't far off what the EK 2.0 does, when you think that a res loop has no radiators in it just a couple of blocks flow isn't really as important as in a "normal" loop so 300LPH is fine in most setups. When I was using just a CPU block a single res running off its own pump was cooling a 4.4ghz i5 with no trouble. The things I found with the Reserator that earned it the bad rep it seems to have on the internet are the following:
1: The supplied tubing was 8mm ID
2: The supplied fittings are sized for 8mm ID tubing
3: The snorkel issue
4: It was designed to be silent, not to cool massively overclocked CPU's, some people have difficulty understanding this concept and so bash them for it :S
Hope any of the above helps.

Most helpful, thanks.
I think that two in parellel should work. I am no physicist but I can't see why not. If one pump is pushing more than the other then it will move more water out of one tower.
But it will then push that water through the t and end up in the same place putting higher pressure and a better flow rate through the computer.
When it comes out the water will have to ^decide^ which pipe to flow out of. If one tower had a lower water level than the other then the water would preferentially flow at a faster rate into that tower as it would have less work to do to enter the tower. I think that would essentially self level the two towers regardless of the rate that water was being pumped out.
I think it would be OK even if you turned one pump off but obviously you would lose half our cooling capacity.
The other advantage of running them like that is that if one pump fails then the other will at least keep things in check until you notice.
The only way to find out is to try it I guess but I am pretty sure it should work. I will start with caution to avoid covering my carpet with red dyed water and if it doesn't work then I can always mod one tower.
Thanks!

I can confirm that two reserators linked in parallel with both stock pumps running works flawlesly. There is more throughput of water as you have two pumps pushing through the loop there is a biger body of water to soak up initial heat and then double the surface area to dissipate from.
There is a slightly ludicrous 5 litres of coolant in the system but it is as silent as ever and now has the heat dissipation capacity to cool my components easily.
It is not cheap but it is silent!
