I just installed version 3.2.05, but my hard drive heads still make the same "hunting" sound at a 1 hz rate as long as the app is running in the background. Shortly after installing this new version, my Firefox browser started crashing all of its open tabs. I tried refreshing Firefox, and that made no difference. Then I uninstalled, rebooted, and reinstalled Firefox and it still crashed. Since the only program I installed today was your app, I uninstalled it, and Firefox immediately stopped crashing. It seems very unlikely to have been a coincidence. As of now, I have no version of the DPS G app installed on my PC.
I built this system using the TT Level 20 GT RGB Plus case, TT Floe Triple Riing 360 CPU AIO, TT Toughpower IRGB Plus 1050W 80+ Platinum digital RGB power supply, and a total of 4 TT 200mm riing duo and trio case fans, 5 TT 120mm duo and trio fans (including the AIO) and 1 TT 140mm duo case fan. With an analog sound pressure meter located 6 inches from the back of the case, it is so quiet it doesn't reach the lowest number on the low scale--but it looks to be about 32db during normal system operation (not benchmarking). This is why I am able to hear the hard drive's heads hunting when the DPS G App is running and stops when I close the app. I doubt that many systems would be able to hear their system's spinning hard drives.
