I’ve just completed a build using the above PSU and the fan on PSU is very loud, you can even hear it wind up to full speed and wind down again when switched on/off. I appreciate it’s a cheaper PSU but didn’t expect it to be so loud. I went with a quiet cpu cooler to try keep the noise down but seems pointless now. Some of the online reviews for this comment on it being nice and quiet. Do you know what might cause the fan to be so noticeably loud or could it be simply a faulty psu?
