Thank you very much for pursuing this - it works! Unfortunately, I noticed a small performance issue when monitoring the chassis and pump fans. If I'm playing MS Flight Simulator, I get microstutters about every second when AIDA64 is monitoring those fans. If I use the previous version that doesn't monitor the fans, 6.60.5900, I have no microstutters.
After some troubleshooting, I noticed the same behavior if I use HWInfo and monitor the chassis and pump fans. HWInfo pops up a warning if I want to monitor those sensors. It says "Access Embedded Controllers when supported. This option can cause stability or performance problems on some machines when enabled."
I suspect the Dell implementation of Embedded Controllers is causing the microstutters when I choose to monitor the chassis/CPU fans. I guess I will not monitor those fans and just continue to monitor temps for the CPU and GPU.
Once again, thank you for your efforts!
