@Mayhems Rep

Hi ive been pulled into this tread :).

Ive owned that res in the past and we've seen this happen when the left side has no flow and the right side is running fully and the left side is a kind of back up res. This fluid needs movement as its a nano fluid and with out it this will happen.

Either use left side "in and out" then got the right side" in and out" or completely close off one side of the res. Thats all you can do.

Thx mick, bit of a design flaw from koolance then??
Probably got 2 options then,
1. Run dual loop
2. Get rid!!

@MICK, would a clear/dyed fluid do the same?? I know the left side would still be redundant but would the fluid separate in some way??

You can split up the loop.
The problem will come going pump->pump without this bypass, the churn will bubble and introduce a lot of air.
If you take it out of one pump, off to some components, then back to the second pump, they should be fine with the original (non-bypass) acrylic.

So:
res left/out
420,
240,
cpu
res right/In
res right/out
gpu,
420
res left/in

But that's just a guess, I'd need to go through your loop to rearrange it more appropriately

Thx for the reply's guys, if you clicky log in sig it will give you an idea of where things are.
I like a clean look on the mobo side, I do have loads of options with my set up but may hold off and grab an EK monoblock, also have another res/koolance tnk-501 and an EK top and enough rad space to cool way more than I have currently!!!

Rad size's are
420x85
420x45
240x45

Could even add a 120 on the rear/exhaust if it helped with the look of the tubing.
 
A Clear fluid would be fine but the left side is literally stagnate which isn't good over time. As a PO i think its one of the best reses and best looking reses created tbh .. but yeah there is some design faults with it.

Or just remove the bypass so the coolant enters the left side?

If you do that it will go in the left chamber, get pumped out the right chamber and equalize via the link between the two chambers at the bottom. (over time the water levels in the two chambers will become uneven due to the pressure, this can be fixed by undoing the fill ports to let it equalize then redoing them.
 
You could get both compartments to be used and thus churn by removing the bypass link thing and operating the pumps as though they were set up for a dual loop, BUT have the outputs from each pump join at a y splitter or t before going to the rest of the loop so it forms a single loop line. Fit a non return valve to the output of each pump so one pump can't try and back feed into the other. You could try it without the NRV and see how it goes, but I would recommend using them.

Then fit another y splitter at the end of the loop after the blocks/rad, i.e. just before the reservoirs to separate into two lines again. This way you will get churn in both res's, and since the pressure drop each pump will see *should* be identical, both pumps should run efficiently with equal flow through both compartments. Make the lengths of tube between pump/res and the y splitters identical to ensure this.

As seems to be concluded in the main thread, the issue is the second compartment appears to be completely bypassed with operating this setup as a single loop using the supplied bypass link.

If after doing this you find one side drains out it will be because the flows end up not being equal despite it being theoretically sound. In this case the only thing you have left if you want to avoid a proper dual loop is to dismantle the res and drill a hole between the two compartments well below the water line, so that they are no longer isolated from each other. Wouldn't have to be a big hole, and you could bung it up with silicone sealant if you wanted to isolate the compartments again in the future.

Assuming you only have one rad as the reason why you want to avoid a proper dual loop.

You've clearly not read this thread,
3 rads
2 loops would be cool, gets the opportunity for multiple colours, but 2 loops mean twice the chance of failure.
Y splitters are a bad plan, he would be much better having the pumps split up so the loop goes through some components before meeting the second pump, this will prevent excessive churning.
Drilling is pointless as the res are connected already, they are not isolated, there is a connecting plug at the bottom
 
A question for those that may possibly know

Due to the problems with the res I'm preffering the idea of going down the dual loop route, will the single 240x45 rad sufficiently cool my 4930k at big volts/clocks circa 1.4v???
Due to the warmer weather to keep my gpu speeds up I'm having to run the CPU on offset mode to help with temps. This would leave a 420x80 and 420x45 just for the gpu, overkill I know but it likes to be kept cool!! Obviously all this is aimed at benching. Any advice on this matter would be great ;)
