Greetings,

I'm using psu from bladecenter and I wonder if theres a chance to manage eg. fans in this unit. After turning them on, they're spinning at max speed (after while) even when nothing is connected to the PSU. Air blowing from the back is cold. I have few questions about that:

1. Is there any way to manage fan speed (reduce it)?
2. PSU only connected to AC draws about 70W (fans turned off) from the wall - is it normal?
