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

Hello,
I've moved this to a separate thread.
Ive rolled back to 4900 and the sensor page is now blank, the process is stuck detecting and end task process does not work as I get "access denied" this is persistent in removal and re-install of AIDA 64 ex

can you tell me if all check boxes ticked in the stability page for the following, which one 
ASUS WMI
ACPI ACCESS
ASUS ROG

Thanks again for the help

Hi,
All of the system fans are no longer appearing in the sensor page Using AIDA64 extreme 5.99.4944 Beta
RAD 1 header
RAD 2 Header
Chassis fan
I cannot remember when it happend,  just noticed another post and I checked mine. same problem
 

Dir sir/madam,
I have an ASRock B450M Pro4 motherboard and I saw in AIDA64 (latest stable/beta versions) that my board has a really high VRM temperature near 100°C. Moreover, this temperature would not increase/decrease much when my CPU is overloading/idle. I touched the power chokes and it doesn't feel like boiling water. I think this might be a bug. 

Hi All, 
Firstly I love AIDA64. It is so feature rich I can't believe I used anything else for so long! I spent 5 hours yesterday fine tuning my LCD panel display on my Android Tablet!
I am running a Threadripper System with a ASUS ROG Zenith Extreme X399 TR4 Motherboard. 98% of the sensors are there there, there are just a few missing. For the Fans the latest AIDA Beta shows CPU and CPU OPT and CHA Fan 2. What is missing is CHA FAN 1, H_AMP_FAN, W_PUMP+ and the 3 CHA FANS on the extension board that Plugs into the EXT_FAN header.
As I am running a TR system that runs warm it important to be able to monitor the H_AMP_FAN and W_PUMP+ connectors as that will tell me if my Liquid Cooler is operating properly. 
Let me know if I can provide any other info or testing to help.
Regards,
Lachlan.
