Dying Power Adjust 2 Ultra?

Saturday, November 24th 2012, 11:40pm

Power Adjust ultra normally runs five fans. Today I also plugged in a High Flow sensor.
First thing I noticed after a while was the fan rpm quit showing up.
Then three of the five fans won't run. It apparently won't ouput enough power to start all five fans.

I can plug the five fan harness into one of the fan outputs on the AQ5 Pro and they all power up just fine.

I've tried resetting the firmware just for grins but apparently it shipped with the latest version.
I've unplugged/plugged the power connection. (with power off)
I've restarted, rebooted and recycled 50 times but no change.

The flow sensor output works fine.

I don't really know what else I can do, can I assume the unit is dead or dying?
Will it not operate with voltage output and a flow sensor simultaneously, and I bricked it somehow?

I'm limping along by swapping some things around. Right now the PA2 is running a single fan and a flow sensor. The rpm and voltage is showing up now but the power % will not.
Actually it seems like it's pretty much stuck on 6.7v running the tiny fan that cools my pump heatsink.
I think it's done for.

what happens when the high flow sensor is removed from the PA2?

And which High flow sensor are you useing?

AMD FX-8150 OctoCore O.C. 18% to 4.2 GHz on ASUS M5A99X EVO with 16 GB Corsair Dominator W. C. RAM, 2 nVIDIA Geforce 560TI W.C. in SLI, six Western Digital drives for a total of 4.07 TBytes, AquaComputer Aquero 5 Pro, AquaComputer D5 pump, Multiswitch USB, tubemeter and Kyros CPU block. Two coolant loops,CPU & SLI, MB, RAM and AQ5, with two flow meters. Running Windows 7 Professional 64, and using Open Hardware Monitor v0.5.1Beta Aquasuite B16 hardware temps.

This ^

If you are using the newer mps type of flow sensor it is designed to be plugged in via USB or the aquabus, not the 3-pin flow header, which is for the older style mechanical flowmeter. Perhaps this is causing problems?

Guys I'm using the older high flow sensor, not the MPS.
Removing it does not change the output of the PA2, ,so I decided to leave it on. However the PA2 seems capable of only producing about 6.7v, and will only run one or two fans.
It seems crippled in terms of power output, as I said it was running 5 fans with no problems before.
Probably merely coincidental that the PA2 started failing when the flow sensor was added, I'm thinking.
