a partcle that just slows it down (and sticks to it) would be very hard to find. If that would be stopped or blocked because some particle in the water it would show nothing. If there would be a problem normally it wouldn´t show any value at all because there is only one moveable piece in it. If the flow meter readouts were accurate, this should not be possible.ĭoes anyone have any flowmeter troubleshooting suggestions? Can they be opened up and maintained?Īs i said before: Its more than unlikely that the sensor itself has a problem. The system was maintaining a temperature delta between the measured coolant temperature at the GPU and the core temperature of the GPU of only between 2 and 4C. I loaded up the system with a loop of heaven benchmark at 4k, maximum quality settings, vsync off, on a highly overclocked Pascal Titan X and let it run until the system reached a steady state. I did some follow up testing with the system assembled and running, and I believe I have confirmed that it is the flowmeter readout that is incorrect, not the actual flow that is diminished. To eliminate this as the cause, I have tried plugging the Aquacomputer flowmeter cable straight into the aquaero, with no chance in readouts.Īnyway, I'd appreciate any suggestions anyone might have on troubleshooting this issue. I was using a 3 pin fan extension cable to help the wiring reach the Aquaero. I have also verified that the calibration is set accurate for my flowmeter ( 53068 ) The old Aquaero still functions, (just without PWM port 4) and it confirms the same flow readings as the new one. I have confirmed it is not the Aquaero itself which is the problem. G.) Old flow numbers were erroneous and too high? Looks like historical version downloads are not available, so I cannot test with older versions.Ģ.) Loop configuration and pumps are otherwise exactly the sameģ.) Both D5 pumps are running just at about their specs of 4800rpmīased on the erratic decreasing flow readings, and the fact that everything looked and sounded normal when I filled the system, I am leaning towards that the readings are wrong, and not that the flow has dropped, but I am not sure.Ī.) New version of Aquasuite software has a bug?Ĭ.) Flow meter wire is bad resulting in poor connection to Aquaeroĭ.) Air bubble is caught somewhere in the loop or in the flow meterĮ.) something has gotten into the loop and is causing an obstruction slowing flowį.) My coolant is somehow more difficult to push through the loop than pure distilled water? (Seems very unlikely) When I first power it up, starting at about 1.1GPM, but gradually getting lower and lower over time.ġ.) Aquasuite did just update to the latest version (x14 to x16 I think based on release dates, but I didn't check what version I was on before). The problem? Now my flow with one pump is reading as anywhere from 0.3GPM to 0.6GPM (~70L/H - 130L/h) and my flow with both is reading anywhere from 0.5 to 1.1GPM (~110L/h - 250L/H) a significant drop from where it was before. Filled it up with my real coolant this time (EK Cryofuel) and started up the new Aquaero and the pumps. Due to essential items shipping first during the pandemic (no complaint from me there, essential items are more important than my hobby) it took a while for them come in, but I finally got them. I also ordered a whole new complement of fans from Arctic. At some point in that process I somehow damaged my Aquaero. Of course I didn't discover this post on th eforum right away, so I was trouble shooting pulling fan cables, reconnecting trying to figure out what was wrong. I had bought Noctua iPPC fans, and they were not cooperating with the Aquaero due to this issue. With both pumps running that number went up to 1.6 GPM (~365L/H) With one pump running I was seeing 1.1GPH (~250L/H). With my dual pump top I was getting great flow values as measured with my Aquaero. I had done a few flushes and test filled with distilled water. This is the build that has had just about everything that can go wrong with it go wrong.Ī couple of weeks ago, I thought I was close to finishing the build. I have had a rather weird issue which I am hoping I might poke your brains with. I am in the process of building a rather large loop for my Threadripper system, which I am documenting here.
