1st attempt at a custom loop

iv just had a thought (too late because the waters in!).
the way iv run the cpu block and gpu block (in parallel) iv got no way of knowing what the flow rate is through both of them ie the cpu could be getting 90% but the gpu only 10 doh.

im ready to switch on assuming it boots fine il leave it idling and watch the cpu and gpu temps like a hawk if either spikes il have to rethink the loop :(
 
Why didn't you just run pump to rad, then gpu, CPU, res, pump??

One simple loop!

Just my two pence pal but it would have been simpler, cleaner looking and less tubing for better flow.

because that would put the pump in the hot water from the cpu and gpu.
also it would take the hot output water from the gpu then put that on the inlet to the cpu which should be as cold as possible

iv done it pump-res-cpu&gpu-rad-pump

all the y splitter is doing is taking 2 hot feeds and putting it into a single hot feed for the rad

if it runs uneven id get a second pump in run it like this

res-both pumps-cpu&gpu-rad-res
 
One word!
Equilibrium............

Edit:
If that is a DDC 18W, it is more than capable of running through CPU block, GPU Block, RAD & RES!

2 words please elaborate
yes thats the pump the reason id get another is to put 1 in each channel (1 for cpu tother for gpu) purely to garauntee same/similer flow
 
I think you have missed one important step!
RESEARCH, RESEARCH & then some more RESEARCH.
Difference between single vs dual loop is so minimal, it is not worth investing in dual loop setups for even a dual GPU setup + hot CPU!

Water in a closed loop system will eventually come to its Equilibrium.
In other words, water temp will be the same any where in the loop given time. It is the RAD(s) and/or Fans duty to dissipate the heat from water to air. As long as the heat transfer is active, your loop temp will be the same. There may be a couple of C deference just after the blocks to start with.

By having multiple outputs from the RES and having multiple outputs combined from the blocks you are assuming couple of things(at least).
The distance of the tubes from and to blocks are the same?
Both blocks have the same restriction?
oh and RES feeds both tubes equally?

Also having 2 pumps in serial or parallel will not make you have "double the pump" effect!
 
i have researched but i dont buy using the output from a heatsource being a sensible feed for something your trying to cool.

the only reason id go twin pump would be to ensure equal flow to both gpu and cpu i neither expect or need any more total flow.
 
Surprised if you are getting any flow at all, the pump is connected wrong, you have the inlet of the pump connected to your bottom radiator, you may want to switch them around;)

Also as above, it will make no difference what tube goes to where first, the only important thing to get right in a loop is to have the pump being fed by the reservoir, to which you have wrong.

Here is the order you could do it in.

the pump is on the hot side if i do it thay way though i could go rad-res-pump i suppose that would keep it on the cold side

i will redo the water loop when i can get the damn pc to actually work! atm itl work for a few mins then switch off then itl restart every few seconds not even getting to post

il do the loop this way

res-pump-cpu-gpu-rad-res does that sound better?
 
Go with whatever is tidiest but res must be before and above pump so that mavity feeds pump at point of turn on.

Going by you pic it looks like you attached the res to the outlet of the pump and that rad to the inlet.

Does the pump sound ok? If I'm seeing it right you could have fried it. The system is like turning off due to temps, have you checked with hardware monitor etc?
 
Yeh the pump is fine the loop flows fine aswell
The pc deffinately isn't switching off due to temps it was doing exactly the same before I put the water loop in

The only time it made to windows the temps were all in the
20s

Please do that now and get rid of that Y Splitter, everyone so far is right about the equilibrium of the loop and you could put temp probes and see very little difference in the temps (1-2c as stated above)
 
remade the loop in this order

res-pump-cpu-gpu-rad-res
alls fine with it no problems

the pc itself however STILL wont boot! ocuk swapped the mobo for me today but its still doing the same thing jesus christ this is annoying :(.
im taking the tower itself in tommorow an just beg them to make it work!

iv been over everything iv done time and time again and im certain iv done nothing wrong
