- I have two Laing D5's both without RPM sensors, each one is connected to a PA2. Is it and possible to controll the speed of them and get a RPM reading? I heard that you could make a "false" tach signal for the purpose of controlling the pumps if they don't have one themselves, how do i do this?

- Im getting low numbers (~150l/h) with 2x Laing D5 @ full speed, they are connected in series. I have the following parts in my loop.
- 2x 360mm Rads
- 1x 120mm Rad.
- 1x EK Supreeme LTX cpu block.
- 3x Coolance VID-AR697 (6970 full block)
- 1x AC "High flow" flow meter.
- 2x Laing D5 In a Coolance 452x2 res.
- 2x Coolance QDC.
- Total of 15x 90degree bends.

I would asume that i would get more then the 150l/h im seeing now?

http://martinsliquidlab.org/2011/03/09/laing-ddc-1-ddc-1t/ Take a look at this Didn't see how to mod RPM signal

I have seen this and first of all its the Laing DDC not the D5, secondly he only thinks its RPM, but no tests done. I dont want to drain the whole loop and take the pumps apart so a false RPM signal is perfect, i just want to be able to controll the speed of the pumps

Hi Eggy88,

Did you set the proper calibration value for the flow sensor in Aquaero? The default one is too high. That would give you lower flow readings.

The calibration value for the high flow sensor is 169. It can be set from Aquasuite or directly from Aquaero.

Kind regards,
Boris.

Yes i have changed it to 169. With the default 256 i got ~100l/h.
Is not the 150 l/h abit low for my loop? The loop is not 100% finish bleeding so could get some more but 150l/h is way less then what i tought i would get with dual D5's.

That's funny as my Ac high flow also reads 150 lh, which I'm worried about being too low also. Only using one D5 though

What does your loop look like?

I would asume thats OK? 150l/h = 0.7Gpm. You have 3 rads, + dual gpu + cpu and the small block on the A5. That combined with all the bends etc looks ok. I get the same with dual pump. And i only have 1 gpu more, but the cards are running in parallel so should be litle to no restriction.
