OSD Fan readings problems and CPU temp (Asus P9X79 + Corsair Hydro H100 v2)

[Ojustaboo]

Hi

A few odd things. I've recently added cheap water cooling to my PC.

It might be a misunderstanding  (or reconfiguration) on my pat. 

1) Sometimes when I start the PC and AIDA64  auto starts, it only shows the 3 white fan options as shown in the bottom of pic "Turn on PC".

If I close AIDA64 and restart it, or reboot, it comes up with the 5 fans it should have (see bottom of pic "Restarted"), 

2) very occasionally it starts correctly by showing the 5 fan options, but will say both the GPU Rad fan and the Temp Side Fan are 0 RPM even though they are spinning (sorry haven't got a pic for this)

Note, Power supply fan should be 0 RPM as it's a quite PS that only starts the fan if needed

3) With my CPU watercooler, I installed Corsairs iCUE fan control software (I presume this is needed to control the fans?).  That software shows completely different CPU temps to yours. When running your Stress Test, (all in C)

After 40 seconds, yours says 39 , iCUE says 33.7

After 2 mins, yours says 40  iCUE says 34.3

After 3 mins yours says 40  iCUE says 34.8

After 4 mins yours says 41, iCUE says 35.1

After 6 mins yours says 41, iQUE says 35.6

After 11 mins yours says 42 iQUE says 36.1

Pics of the above attached.  I left it running for a while longer, but the temp stayed fluctuating  between  41/42.

Then after I'd stopped your stress test for a couple of mins or so your s/w says 29, iQUE says 34.6

First of all, make sure to upgrade to the latest beta version of AIDA64 Extreme available at:

https://www.aida64.com/downloads/latesta64xebeta

After upgrading to this new version, make sure to restart Windows to finalize the upgrade.  That should help about issue #1 and #2.  If not, then please let me know where exactly are all your fans connected to (motherboard or water cooler/coolers), and whether the motherboard connected fans are "iffy" or the ones connected to your water cooler/coolers.

As for #3, as you can see on the AIDA64 OSD Panel shots, there're quite a few thermal readings available for your CPU, namely "CPU", "CPU Package" and 4 core temperatures.  iCUE could indicate any of those as CPU temperature, or it could simply show the liquid temperature of your water cooler as CPU temperature.
