New PSU,& pc fans now rev on boot.

[FlyingFish]

I've changed from an evga 850 Gold to a Dark Power Pro 12, nothing else has changed, apart from the PSU and cables.

Every boot, I hear the fans rev for a split second which my old PSU didn't do.

Is this just something I live with, or a modern feature? Anybody else's do this?

I've not looked in the bios yet, the pc boots too fast for me to remember. So I'm not sure if there is some sort of power up feature I need to check. But nothing has changed apart from the new PSU and cabling. Previously boot up was near silent.

I only turn the pc off through windows.
I've got fan curves set for my case fans in bios.

It might even be the PSU fan revving up, I'll need to open the case and check.
