Hey it's FIXED! Great job and THANKS!

Thank you for your fast response. I uninstalled the old version and used CC Cleaner to clean the registry and deleted the remaining folder from Program Files x86 then restarted my computer. I removed all the fans and then tried a different fan in the CPU OPT header, a Noctua NF-12 this time. The beta Aida64 from the link still reports that header as Chassis 1, and the real Chassis 1 on the motherboard as CPU OPT.

It's a GA-Z97X-UD5H, the regular version.

Hi, I've been having this problem since the beginning of the year, and even on old editions for some reasons, Aida 64 mixes my CPU OPT fan speeds with my Chassis 1. I've double checked in BIOS and checked my fan cables. My Chassis 1 is a Thermaltake 200mm and my CPU OPT is a Cougar 140mm. Both are PWM fans inserted into PWM headers, with BIOS set to Normal speed for the Cougar, and 2.5 * PWM / C for the Thermaltake.
