Hi just wanted some advice, will post pic below.

I have a Koolance RP-45X2 dual res running 2x D5's in parallel and as you can see from the pic in the left chamber the mayhems ice white nano fluid is breaking down into 3/4 layers, both pumps are working and i have contacted koolance to check that i have it set up right and they say i do and the reason why its happening is there is no turbulence in that side of the res.
I have tried running pump on left faster than right and even turned right hand side off but results are the same, not too happy with this at all considering the price but my question to you is will this affect performance in any way??? what are your thoughts as i am going to contact koolance again.

thanks,
nick

edit:fluid looks worse in real life than on pic

That picture was over the 1280X size limit. Use spoiler tags if you want to show a humongous picture.
soz!!! forgot to resize, DONE!!

just shut left one off for 5 mins and no change, i'll give it a rattle to see if theres any air, been running for a couple of months like this so doubtful, but if there was an air bubble in the left chamber it could possibly stop the chambers mixing???
 
also using pump controller as shown in pic, both pumps appear to be working but hard to tell if off is fully off on the controller, the extra pump i installed made a loud noise at first but it was dry so shut down imediately and primed it, seems ok but they both make different humming noises possibly being due to the fact that one pushes and the other pulls??


 
The 180 piece is on the pump outlet, it can't be removed from there or the pump would be redundant, I only asked to double check :p

I believe it's the bypass piece not allowing the fluid coming in the inlet to circulate the left res before exiting, but I only have pictures to work from, I can't be 100% on the flow.
you could look and judge for yourself if this seems the culprit.

@ubersonic, his pumps are series

think i may just have to pull the res out and switch the bypass back, it perhaps needs to enter the res twice to allow it to mix, just wont know for about a month as the settlement process can take a while!! it is an optional alteration as stated in the manual

Also for serial operation, an acrylic bypass piece is
included for optional installation. This can improve
performance by preventing coolant from entering
the reservoir twice. With this installed, the reservoirs
can also be combined
 
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??
 
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 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 ;)
