Dual Water G5 case mod

Dual Water G5 case mod completed

Very quite group we have here thought my post may have prompted some discussion maybe even a little feed back ?

Well I do not understand your water loop(s) and why two rads?

I can see that there has been a lot work put into this system.

Are you over clocked?

Good modding,

Very nice build! You have some serious cooling power in there... I like how well you got every thing to fit!

After doing research i found out that a fully water cooled, overclocked system would require more that a single 240 mm radiator i could have re positioned the power supply to take a 360mm rad but after looking at your builds and others in this community i decided i wanted to keep the PSU were it was it also maintains more of the integrity of the original case design.
Armed with this i decided to put a 240 mm rad at the front and place a single 120 mm radiator at the rear this also helped me solve another problem. when you have a single loop cooling CPU, GPU, VRM, and RAM the last component in the loop gets cooled? with hot coolant, with the dual loop set up i have the CPU, GPU on one loop ( the large tubing you can see ) and the VRM and RAM cooling on the second ( smaller tubing ) loop, both loops feed back in to the reservoir mix together the pump then pumps it to the 2 radiators and it all starts over again most of the second loop is not visible as it connects mother board components you can see just small tube to the right of the pump that feeds into the rear rad and the a smaller tube to the left that returns to the reservoir

This may seem like overkill but Perth Western Australia summer temperatures average mid 30s degrees c topping out at low 40s trying to air cool in this climate is difficult when overclocking i have tried and became sick working next to something that sound no unlike a hovercraft

Phil thank you for the loop explanation. Is the pump a single chamber or dual chamber one? Did you have to use flow restrictors to get adequate flow into the smaller tube circuit?

From what I've read this is largely a myth; because the water is moving quickly through the loop there should only 1 or 2 degrees difference between the hottest and coolest areas.

To answer the last post i totally agree, this is my first full custom water cooled system and found a lot of posts claiming that the last component get cooled in hot coolant. but having now completed it and used it for the last 2 weeks i would totally agree with you the flow is much to quick to cause any of these issues
This in part Neil also answers the question as to flow through the second loop, the pump housing is only a single chamber with 2 outlets ( with a D5 pump ) but the volume of coolant that this set up delivers is to me astonishing, the smaller tubing will obviously not flow as well as the larger tubing but from my observation the small amount of drop off in volume dose not warrant worrying about especially as the components on the second loop generally produce less of the heat anyway

This isn't really true. The change in flow rate as you increase the diameter of the tubing won't increase because the water is still going through the holes in the fittings and their diameter doesn't change from fitting size to fitting size. They are all G1/4.

And correct, the last item in the loop is not cooled with "hotter water." That's because the temperate of the water in the loop reaches equilibrium rather quickly. If you have more than one GPU, their temperatures will be slightly different though, not by much, less than 5*C.

Thanks i will head over have a look
