Odd PSU behaviour

[Boozebeard]

So, I just changed over to a be quiet darkpower pro 550watt psu. There's an odd problem when I shut the system down. All the fans that are connected by molex continue to spin and the leds are lit. They spin much slower and it almost looks like they start to slow down a bit and then receive another jolt of power and go a bit faster again. Over about 2 minutes the fans slow down and the led's dim until they all turn off.

Any idea what this is about? Am I just going to have to put up with it?

Wonder if it runs the fans to cool down the system for a few mins then turns off, my Corsair used to run it's own fan for minute or too and wonder if yours does the same, but also with one molex lead.

What does the manual say.

i've had psu's before that the psu fan spins for a little while after shutdown to cool the psu down but not had one which ran case fans for a while also but it may be a feature of the psu.
