if you dont run the TT controller software the fans will just spin at 400rpm(if its set at PWM+Performance mode).
thats why some people has problems with overheating because their fan rpm is not ramping up.
i noticed with when doing stress testing and gaming. the whole time my TT ring premium fans are jsut spinning at 350-400rpm the whole time.
when run the software, the fans then spins up to 700-1000 to control the temperatute.
so i really need to run the software at startup. but its annoying because it triggers the UAC.
i cant turn off UAC because its not advisable to turn it off
attached pic is how slow the fan rpm is when im at desktop use and when the software is not running.
ps. my temp is 33c as seen in the screenshot. when gaming and stresstesting my max temps are only 50-55c (aio is 240mm rad)
