Project: 900D dual loop

Can I ask why you going with a dual loop? I only ask as I’ve always felt that with a system with two pumps you’re better off running them in serial rather then parallel that way you have an automatic failsafe should one of them go wrong.

It's mainly for the look of two reservoirs, two pumps and two colours. I have aqua computer flow meters which have an alarm if flow drops suddenly so that is my fail safe.
 
Trying to decide on locations for the pumps. I think this will probably be the location.

I think I am going to try something a bit strange. I haven't seen it done before. The pumps have two outlets and I was thinking of running two loops per pump. The purpose of the second loop per pump would be to run to an aquacomputer flow reader hidden where the front fans would normally be. This would require pass through connection on the coldzero plate that has been removed.

I am not sure whether this will result in accurate flow readings as there will be far less resistance on this sub loop. However I am far from experienced on watercooling so not sure if pressure equalises over a loop like temperature does??

Another reason for me considering this strange set up is that I want a really complicated tubing route.

I did my first ever bit of cable sleeving today. I sleeved the four cables from each pump into one larger sleeved piece. Can't believe how much better it looks. Got to order more sleeving now.

Run into an issue. I cracked the coldzero mid plate. Stupidly I tried drilling a hole whilst it was still in place
Naturally it cracked!

It has worked out ok I guess. I have marked all the holes to be drilled on the cracked piece, there are quite a few! I can now use the cracked piece as a template to get perfect holes cut on the new piece once it arrives.

In the meantime the position of the pumps is now confirmed. This picture was taken before I cracked the mid plate.

I am a bit limited to what I can do at the moment due to the cracked mid plate.

I was hoping to get the bottom reservoirs plumbed and both drain ports installed.

Instead have I installed the two flow readers into their positions on the front coldzero panel where the fans would normally be. I have used pass through connections and intend to run these as a secondary loop per pump. Only time will tell if these is a good idea or not.

I am awaiting parts from ocuk, ekwb, coldzero and various suppliers for cable sleeving. There probably won't be much progess until these parts start arriving next week

Ok so not much to report on due to waiting for parts. Run a few more pieces of tubing. It seems petg is easier to bend when much hotter, it only took me a few minutes to bend these two pieces. Does anyone know where to buy longer pieces of this 10mm silicone cord insert? I have some 1000mm bitspower crystal link but the ek cord is onot about 300mm long.

Ordered all the parts and equipment to make my own custom psu cables. Anyone got any idea which two colours I should go for? I am completely open to suggestions. Obviously I would theme my cabling based on the two fluid colours.

Sorry for the delay in updating. Due to waiting on parts there was not much that could be done. Today I haveam aged to get both drain systems installed. New midplate from coldzero is installed with pumps mounted.

Now I have to spend the rest of the day doing some elaborate tubs bending.

As you see I have used normal tubing as I had some left from my previous build. I also used the xspc fittings from my old build. I must say I am not a fan of xspc fittings. I have had multiple fittings which dont rotate properly and some threads are broken. I will not use their stuff again.
 
So it has been fairly rubbish afternoon and I haven't had much success with bending tubes.

I have given myself some tube routes which are quite simply beyond my skill set. In particular the tubes coming from the front of the pumps only have about 28mm clearance before the case window. I have decided to order some fittings to help complete the build.

I always intended to not use any 45 or 90 degree fittings, however this is simply not realistic with the tubing routes I have to make. I intend on upgrading this build in the future so it will always be a work in progress.

On the positive front I have ordered bespoke made cables / lighting from Pexon PCs.
 
It's easy to bite off more than you can chew sometimes with these types of builds but if you don't push yourself you'll never progress! The routes you've already accomplished are not insignificant so don't be too hard on yourself!
