Hi all, I can totally agree! I registered especially here, because of this annoying problem.
My PSU is at 1000W use (57% of my 1500W RGB PSU), and it's whinning at 1200 up to 1800 RPM! Every 5 seconds it's changing it's RPM. This is insane. It has a hard-wired temperature of 40 C, when this temperature is reached, fan is spinning faster and faster until it reaches 39 C. Then, it slows fan down completely to 1200 or less, so temperature is back again to 40 C in a matter of 3 seconds. This is just wrong.
I am thinking about returning my both 1500W PSU because this is unacceptable. This is not smart power or fan management at all, this is very dumb.
Thermaltake, how we can fix this? Any comment, please? We need workaround right now.
