Hi, I am currently rebuilding my complete WC setup, and are hoping for suggestions on how to connect my system in order to reduce resistance and to maximize flow. ;D

My layout is seen in the figure;



Suggestions on how to connect the waterblocks are higlly appreciated. I am going to use a ID 3/8" Clearflex tube. Currently I have the following serial flow with PVC tupes:
pump> 4x ram> cpu> gpu > mosfet> nb > sb > 2x aquadrive > radiator > flowmeter > aquatupe > pump, and this is running at 24l/hour with the pump @49Hz, and 36l/hour @74Hz (is this good or bad?).

I hope to increase the flow to 30-35 l/hour @49Hz.

The figure represents the current placement of waterblocks, but I am able to relocate the aqudrives and the pump and watertank.

Also suggestions on where to put my (modified, ID 5,6mm) AC flowmeter and the inline temp sensor are welcommed. I have a second temp sensor i the aquatube, and I want to measure the work done by the WC-loop.

I am also wondering about running the my 4 ram block 2 by 2 in paralell, any comments? :

The whole setup is controlled by aquaero, and is placed in a Tt Kandalf LCS with the radiator outside the case.

So all you experts out there, please give me some quallified advices.

Thanks a LOT!

Thanks a lot.

Since my postings, I have decided to go for 2x AC Ramplex in paralell, instead of my four Tt blocks for RAM cooling

So as it seems now, my flow will be pump> ram> cpu> mosfet> nb> gpu> sb> aquadrives> flowmeter> inline-temp> rad> aqutube> pump

This in order to minimize tubing and other practical issues ...

Thanks again, but is disconnecting everything, I found that the combination of AC Alu-block and Tt Green-UV-fluid is a no good, and that a lot of salt (by the look of it some kind of Cu-salt - greenish) was deposited in some of the blocks, especially NB, MOSFET and GPU, but also CPU. This was decreasing the ID of these block quite a bit. >

When remounting, I will be using sterile destiled water together with AC-fluid and Ac clear blue. My hope is that this will solve this problem. This combined with a better hose, and less restriction over the ram bloks, so do the trick. I have also replaced the original 1m hoses to and from the radiator (ID 6 mm) with Clearflex 3/8".

I am not to worried putting the RAM before the CPU, as the ram will not increase the temp of the water much, so my concern in getting the best cooling, is increasing the flow-rate as much as possible ...

All together this should suggest a much better flow. I will inform you about my new flow rates when it is all done ...

Thank for all good advices, here is some update of the last months progress.

After I found the greenish salt crystals, I cleaned every water-block in 2,5% vinegar solution ... (diluted a 5% vinegar from the supermarked 1:2 with water) worked like a charm, all Cu and Al block looked like new. As for the rad, I let the vinegar solution circulate the rad alone for 3hours at full pump speed.

After this i remounted. But put everything in series, as I never was satisfied with either the manifold for the security reasons mentioned above.

The flow was now much better, 41 L/h @ 49 Hz, 69 L/h @ 74 Hz.

Temperature-ratings are now stable at normal working conditions at CPU 37-39C (AMD 4400+@2,64GHz), mobo 30-33C. I run my system at 20% OC 24/7, Aquaro controls everything, and fans usually run at 40% (quiet!)

After running this WC set up for a month now without problems, I can by inspection see slight signs of more salt on my NB block and some salt crystals on the bottom of my Aquatube. My hope is that this is residues of the old problem (from the rad?). Thus I will monitor the development, and clean my system again if necessary. But as long as my flow is steady above 40L/h, I dont bother.

EDIT: I now use ACFluid + AC Clear Blue + destilled water. Also the water her in Norway is very low on calcium (lime).
