I am using an Asus C6H and two Laing DDC pumps in series in an aquacomputer dual top. The pumps are connected to 12v and the sense wires are connected to Cpu and Cpu opt. Using AISuite III and in BIOS it reports ©21,000-23,000 rpm on both pumps (well AISuite reports 9999rpm for Cpu fan). I accept that they can't or shouldn't be running at that speed but is there any way to get the correct speed displayed? Temps are good. Any help would be gratefully received.
Curious. WHY are you connecting them to the CPU and CPU_OPT?
What motherboard you using? and does it not water pump headers somewhere?
Hmm.. Normally DDC Pumps should be running around 4400 ~ 4700 RPM.
Hi UltraNEO, thanks for responding. My motherboard is an Asus Crosshair VI Hero (C6H). Yes, it has got a water pump header but it is a single 4 pin connexion. I thought for quite a while how to power both pumps and arrived at my current solution. I did think of putting one pump in the AOI connector and the other in the water pump mb connector, either wired straight in with the mb 4 pin connectors or just sense wires to the mb and psu 12 v but I didn't like that idea aesthetically [sic]. I had a two way splitter to connect both pumps to the water pump header but I thought that there may be a conflict with both sense wires connected to one header. Also the pumps were supplied with a psu 4 pin molex connector for power and a smaller 4 pin pwm connector for speed and tacho signals. I thought of connecting both pumps into the single 4 pin water pump connector too and just using one of the pump sense wires in the 4 pin connector. There was also the fact that I was using 2 Laing DDC 1T PMW Special pumps (not plus). I accept that at 2x10 watts could have been handled by the water pump connector, rated at 30 watts I believe but I thought it safer to go with the 12v molex connector for power. This seemed about the easiest arrangement. I have a Phanteks Enthoo Primo case and I use the aio connector for the case fan pwm hub. Thanks again for responding.
Hi UltraNEO, thanks for your help. I only have one loop and both pumps are in the same pump top in series. I agree that if I had two loops it would make perfect sense to run them independently on the Aio and Water pump headers.
