How to stop the RT500 Digital fans from ramping up randomly?
The digital screen on this cooler looks slick, but the fans suddenly ramping up like a power drill is just ridiculous—it's almost ironic. The temperature sampling rate on the PCcooler RT500 Digital was set way too high, meaning it was catching every single tiny CPU spike and forcing the fans to bounce between 1000 and 2200 RPM. I tried the 'Silent' mode in the software, but my temps hit 90℃ immediately, which was a joke. I went into the BIOS and stretched the temperature sampling interval from 0.1 seconds to 2 seconds, and limited the PWM step to 5% to stop the sudden jumps. My noise meter showed the fluctuations drop from a jarring 45-55 dB to a smooth 32-36 dB. I actually overshot the sampling delay at first, and my temps spiked to 88℃ because the fans reacted too slowly, so I had to lower the trigger threshold by 5℃. Now it sits comfortably at 68-75℃. I exported the noise logs and confirmed frametimes are rock steady at 5.1-6.4ms.
