hi guys, i'm newcomer. I have a problem here, maybe this forum can help me. I have PSU 550W, for some days i use my PC, it runs moderately silent, but now it is very noisy (for me), i think it is louder than my CPU's stock fan. My PSU is Simbadda (local brand). i need some suggestions how to make my PSU becomes silent without replacing it with other brand (if it is possible) ?
