I live in Thailand. Just bought BR1100CI-AS last week to use with my gaming PC. UPS working just fine but fan is quite loud and constant active during few hours of use, I have to disconnect it since my PC is in the bedroom and I usually left it on overnight. I searched the manual for fan working condition but found none. So I want to ask if the fan in hope if the fan will active only for some conditions, not always on. Or any method to reduce the noise. Thank you.
