Water cooling loop question.
Water cooling loop question.
Hello, I'm constructing an extremely costly overbuilt system with two separate loops and I have some doubts about setting up two pumps within one loop.
I already have the CPU loop fully configured but I'm having trouble with the GPU loop. Right now it appears as:
Res > Pump > Res > Pump > Rad > Rad > GPU > GPU >>>
My questions are:
1. Is it a problem if a pump feeds directly into another pump?
2. Or is it unnecessary for a pump to feed straight into a res?
3. Would this configuration be effective because pumps on either side of the loop push fluid through the rads, then move it through the blocks and pull it out again? I'm really unsure about the exact setup.
I would prefer a layout like:
Res > Pump > Rad > Res > Pump > Rad > GPU > GPU >>>
But using the middle and right-side rads on a Thermaltake Core P7 would be quite complicated to implement and would look messy.
Thanks in advance for any advice or suggestions.
I completely grasp your perspective, and I've considered it before. However, when you think about it, a pump doesn't just push water out—it also draws water in, so removing water from the blocks would likely still make a small improvement wouldn't it? Also, how would that dual pump you mentioned work? I hadn't encountered one like that until now.
Pumps don't suck; it's the pushing motion that moves the fluid through the system, around the radiators and blocks, back to the reservoir at the end. To be honest, even the pump I linked seems a bit excessive, but if you scroll down a bit, you'll see how the reservoir fits properly and how adding a multitop for return flow makes sense.
You don’t have to use two pumps for a GPU loop, even with an SLI configuration—it adds unnecessary complexity and cost without any real benefit.
If you truly need a dual pump system, consider running each GPU in its separate loop if the motherboard allows it.
As coozie7 mentioned, you're adding unnecessary complexity.
The main goal is simply moving water from one reservoir to another at high flow rates; it doesn't add value.
Water flow rate has little impact on cooling performance, and graphics card blocks are already quite restrictive because of their thin design and tight routing.
With two pumps, depending on their type, you could achieve similar results using D5 pumps:

You can also purchase the appropriate housing for this setup, just for reference.
My ideas were that one pump would suffice for two massive rads and two blocks, but using two pumps would clearly improve performance and reduce the effort needed to push through two rads and blocks.
Financial concerns aren’t a factor here; I’m aiming for the top quality.
The approach I plan to take doesn’t add unnecessary complexity, though I’m still unsure about the most effective way to set up a dual pump loop.
I hadn’t considered creating a separate loop for each GPU, but I believe that would make implementation even more challenging.
Seanie I fully grasp your perspective, and I considered it before. However, when you think about it, a pump doesn’t just expel water—it also draws in water, so removing water from the blocks would still likely enhance performance slightly, wouldn’t it? Also, how would that dual pump you mentioned function? I hadn’t encountered one like that before.

Regarding the dual pump you mentioned, it's not something I had encountered before. Pumps don't suck; they rely on pushing force to move fluid through the system, around the radiators and blocks, back to the reservoir. All that involves a forward push motion.
To be honest, even the pump I linked seems excessive. But if you look at the page further, you'll notice how the reservoir fits properly and adding a multitop for return flow would help.
I primarily use D5 pumps, which are very reliable. I've owned mine for years and have a variable flow rate adjuster.
I currently have mine installed on this model:

but I'm planning to use a miltiport top for the return flow.
Thank you for the clarification. I initially thought pumps would only move fluid in one direction, making the second pump in the loop unnecessary. However, I now believe running a separate loop for each GPU, as coozie recommended, would yield better results.
Thanks for the assistance, I initially thought pumps only pulled and pushed, so having the second pump in the loop would not make much sense then.
I believe the optimal choice for the best performance would be to create a separate loop for each GPU, as coozie recommended.
That's a solid idea, to be truthful.
Seanie, if things got worse, a single D5 pump would be sufficient to move through two 480 rads and two blocks without raising temperatures too high. I’d be running both GPUs at their maximum and anything over 60°C under heavy use would be a problem.
