Hey ruffhi, I did do some flow testing of the loop after it was completely finished, and I of course took notes, but after your question I realized that that information never made it into any of the build log posts. So here it is now:

Devastator Flow Rate Testing

The system is one big loop with two Aquacomputer D5 PWM pumps in series. There are six radiators in total, four Hardware Labs Black Ice SR2 560mm in the top and bottom, and two Hardware Labs Black Ice SR2 280mm in front. Even though there are six radiators, these are low restriction radiators.

There are also seven water blocks, but they are all low restriction waterblocks, with the two video card waterblocks in parallel and the two hard disk drive waterblocks also in parallel.

I tested the pumps with various speeds between 40% and 100% to test the flow rates and what it did to loop temperatures. There were two specific speeds where the pumps would make a slight hum noise. At 70% pump speed there was a slight hum, and an even louder hum at 50% power. The rest of the speeds you really could not hear the pumps, and certainly would never hear them over the fan noise.

In this testing I was loading the system with the Real Bench stress test. This really puts just about the max load on the system that you can. This was done with an ambient temperature of 73° F, with the fans all set to 700 RPM and my 4.8 GHz daily overclock profile on the CPU with a 1.25 vcore.

Starting at 40% and going up 10% at a time all the way to 100% and then one final test back at 40% again. It is interesting how the air/water deltas are slightly better with 40% power and less flow rate.




This testing was done April 14, 2019 and shortly after this the maximum flow rate at 100% pump speed settled in at 1.1 GPM which is the same flow rate I’m getting as I write this, and I just now rechecked the flow rate at 40% power and it is .8 GPM.

I could run the pumps at a lower speed just fine, but since they are no louder running at 100% and the loop temperatures really did not vary too much with the pumps set to lower speeds, I would prefer to have a higher flow rate so I just leave the pumps set at 100% all the time.

As to the air/water deltas, the temperatures you see in the chart above are the hottest I’ve ever seen. I did get slightly better air/water deltas when the build was still in my work shop due to better air flow all around the case.

Now that it is in my office under the desk the air/water delta once the system is fully warmed up is usually around 3°C. It will go up a little bit more when gaming, but even this last summer when my office was almost 90°F the highest I ever saw the air/water delta get to was 4.5°C

Those are excellent results. I have noticed the pump noise change with different RPMs too ... and you can dial it up / down to you find a sweet spot re noise.

Re your flow rates, that is radically different from what I am seeing on my PC. My cooling loop ...

  • 2 x radiators (Hardware Labs Black Ice SR2 120.3 Multiport Satin White Radiator - white with white fins)
  • 2 x pumps (Aquacomputer D5 Pump Core | PWM Equipped)
  • 1 x pump header (EK-XTOP Revo Dual D5 Serial)
  • 1 x GPU block (Watercool HEATKILLER® IV for GTX 1080 - ACETAL Ni)
  • 1 x CPU block (Watercool HEATKILLER® IV Pro (Copper AN))

I have gone back and forth with my loop. I started with quite a few hard 90º turns but swapped them out for the triple rotary snakes.

I had one run that I have been thinking about ... I just swapped it from soft plastic to a complete run of fittings.

Flow has always been pretty horrible. At 100%, (pre fitting run), I could get 1.2 GPM. I was running it at about 75% and getting a flow rate of 0.95 GPM. After swapping to the full fitting run, flow has dropped to 0.9 GPM at 100%. I am currently getting 0.65 GPM at 80%.

I thought that one of my pumps might be bad so I installed a on/off switch on each pump. I can either run it with both pumps or turn the left or right pump off. Turning off one pump (either one), cuts the flow rate to under 0.4 GPM. Conclusion - each pump is as good as the other one.

My flow meter (Aquacomputer flow rate sensor "high flow USB" G1/4) could be off? I have ordered a different flow, Barrowch that is in the mail.

I am going to swap back to air and test each component re flow restriction.

I don't think switching styles of 90° fittings will make much difference at all in your flow rate. I remember awhile back now probably at least five years ago, that Martins Liquid Lab did a test with various amounts of 90° fittings in a loop to test how it affected the flow rates, and even with a lot of 90° fittings it really did not make hardly any difference at all. The last time I looked for that test I was unable to find it to reference here. I have seventeen 90° fittings in this build.

I remember reading in your build log that you have a filter installed. If it is the Aqua Computer Inline Filter, those are very restrictive as you can see in this flow test done by fast_fate https://www.overclock.net/forum/25894531-post635.html

I would try to bypass the filter or remove the filter and test your flow rate again if you have not tried that yet.

What radiator mounts are you using for the top? I thought the case only came with 480 drop in mounts, was this changed in future versions of this case?

I took the filter out ... and then put it back in with a bypass. Still fiddling. I have actually moved my PC to a Thermaltake case (sacrilege!) and it is running on air. I couldn't believe how quiet the study is with no PC here. Under air it is about as quiet as before.

Meanwhile, my S5 is downstairs undergoing a minor update (swapping to different fans, installing BarrowCH flow meter, installing Aquacomputer SPLITTY9 active, changing 1 90º turn to low profile version, installing switches for left and right pump, etc).

I will be doing some flow tests with nothing in the loop (res + pump) and then adding 2 x radiators, CPU block, GPU block and, finally, the filter. I will do a write up about this in my thread.

removing 90 degree fittings from the first few inches of your pumps' out can also drastically increase flow as well.

BP makes snake 90s that're a much less extreme bend, they help a great deal in this area. removing the hard 90s from the mouth of my mcp35x2 allowed another 100lph, no lies. from ~120 to 220.

I have those rounded snake 90º in ... and I do have a left turn straight out of my pump. Not much I can do about that. I will have a think about what I can do re pump location.

Where did you learn how to do all this? Have you thought about hiding cables somehow? They stand out...

When I ordered my case it came with two radiator mounts, and there was an option of either 480 mounts or 560 mounts. I ordered my case with 560mm radiator mounts, plus two extras so I have four 560mm mounts.

The case and the mounts did require modification to fit the Hardware Labs Black Ice SR2 560mm radiators however. I covered how I did that on this post Fitting and Mounting the Top 560mm Hardware Labs SR2 Radiators

I also showed how I mounted the bottom and the front radiators on separate posts.

If you have not seen it yet, Post#2 is my Build Log Index with Links which is also linked at the top of the first post.

That makes it easier to find stuff
