I've got the same noise when cold. My reservoir is clean and it has fresh fluid, still makes a little noise. Goes away when warm.
Mechanic's stethoscope says that it is definitely the vane pump. Interested in trying some Mobile 1 ATF or even synthetic power steering fluid as I have some Valvoline Max Life ATF in there now, but doubt it does anything for the noise.
My steering feels awesome. We did aggravate the pump off-road when it was maxed out at lock for around 3 minutes while my wife navigated an obstacle this summer. Fluid got very hot but the reservoir was able to handle the extra fluid expansion.
