Gigabyte's New Odin GT 800W Power Supply

Acoustics and Fan Speed (Ambient 25°C)




Throughout testing we could clearly hear the noise produced by the installed fan, regardless of load, but this is not clearly visible on the decibel graphs. The fan speed begins increasing from around 50% load which equals around 400W of power. Even at a normal ambient temperature the fan began to rotate at a very high speed which resulted in noisy acoustics despite the low temperature. That said, it's worth mentioning that the user can adjust the fan speed to their own needs using the provided software, so if the power supply is being used in a good air-conditioned environment it could surely run at lower speeds and thus lower noise levels. When the PSU is mounted in a system, the noise levels were not as noticeable; this is because the PSU is louder at the fan intake then it is at the exhaust.
