Fan Speed
When testing in a power supply laboratory it is difficult to take fan noise readings as the noise from the Sunmoon test equipment and air conditioning corrupts everything. The next best thing in our circumstances was reading off the fan speed with a tachometer to get an idea for the noise. The ambient temperature during testing held constant at 22 degrees, with 1 degree of variation. Each power supply had a consistent time period of 5 minutes to stabilise between each load scenario.
In my experience the following general relationships apply between noise levels and fan speeds, though it can vary greatly between the type of fan used.
- Below 800 RPM – Inaudible/Silent
- 800 to 1000 RPM – Barely audible
- 1000 – 1200 RPM – Audible but still quiet
- 1200 – 1400 RPM – Moderately noisy
- 1400 – 1800 RPM – Noisy
- 1800 RPM or higher – Intolerable
I don’t think the fan profile is terribly important. If you have a muscle bound system that can come close to occasionally demanding the kind of power this unit can supply then the chances are you’d rather settle on 1400w+ PSU.
I’m surprised XFX didn’t opt for a San Ace fan which is something Seasonic does and is touted to be one of the best if not the best in the the consumer PSU game. Can it really make much difference the in price?
