Aurora-R7, AWCC, CPU pump failure

This is how your check your hardware (outside of Windows).

This is for an Aurora R6/R7 with (Asetek) Liquid Cooler

F12 to run ePSA Diagnostics
First page tests take about 5 minutes.
After it finishes Testing, it should say everything Passes.
It will ask about running Extended Tests that take 4 hours
- If you don't expect Memory failure, you can skip RAM Tests
Click arrow button (bottom right) to go to second screen (detailed Test Results)
Notice all the components that tested good
System Health/ Fans / CPU-FAN is actually the impeller-RPM of Asetek Liquid Cooler pump
- Pump Impeller RPM is constant/fixed and should be between 5280-5350 RPM
TOP-FAN (radiator-fan): around 1160 RPM
FRONT-FAN: 450 RPM (PCIe slots & cool-air intake fan)
HARD-DRIVE: 26c
CPU Thermistor: 35c-54c

On the software side ...

Did you try:
Uninstalling old Alienware Command Center
Reboot
Clean-Install this version:

Dell wants to send a technician to replace the liquid cooling system but the cpu does not get hot under load so something is cooling it lol. I keep telling them at 1440p 110+ FPS on destiny 2 and my CPU does not exceed 58 degrees C....what are your thoughts?

What do you mean by clean-install? I followed Dell’s steps to uninstall from system, remove ACC from registry and install fresh.

Yes, tried clean new install of ACC. No display of “CPU pump” anymore... It just now has CPU fan 100% all the time roughly in the range you explained - 5200-5300. All tests passed and were no issues. Games run good. Is there no problems?

At this point, seems as good a try as any.

Can't really say for sure without knowing your ePSA test results and how they compare to mine (from a working Aurora-R6). 

Another thing to note, my cpu fan speed is not totally fixed. If does vary some but near/within the range you specified 

Results are as follows....what are your thoughts? Everything passes and reports fine. The real only “issue” is the one time ACC cpu pump failure mention and that status dissapearing and now a reading on the CPU fan in the ACC.

That looks pretty good. However, I wonder why the radiator (Top) Fan shows so high? Even after doing an ePSA test (short, skipping ram test), all it's RPM's should be around 1165rpm. Does it always show that it went that high at some point?

The Liquid-Cooler pump is running ... you can see it at 5299-5389 ... which is normal.

Post a pic of what your Thermal Controller usually looks like now-days in Windows.

As I already posted:

- Pump Impeller RPM is constant/fixed and should be between 5280-5350 RPM

So, that is normal.

You get it right? When the Aurora-R5/R6/R7 has CPU Liquid-Cooler installed, there is no actual "cpu fan" ... no fan with blades that push air.

Ok here is a current shot of the AWCC -

I am not sure on the top fan. It passes the tests so I done think it ever goes that crazy. Possibly just under stress tests?

Dell technician is coming Tuesday to bring new replacement liquid cooler just in case due to the CPU pump failure reading I saw that dissapeared and is now no longer reading in the AWCC. This sensor used to be located next to the GPU fan #1 there. CPU fan started at the same time and appeared below in the fan section. Before it was just top and front.

That pic is wrong.

Notice PCI_SENSOR looks wrong (looks like a "variable name"). That should be "Ambient Sensor".
[CPU Pump = Running] block is missing completely.

In lower Thermal Control section, there should ONLY be Front Fan and Top Fan.

CPU Fan should not even be there. Mainly because you don't have one. Pretty sure that should be up in the top section, and labeled as "CPU Pump = Running".

Also, on all my Aurora's , I use Manual and a nice up-hill Curve.

I agree there are issues. Any thoughts on how to resolve?
