Does the fan inside the turbo spin when the car is under 1000 rotations per minute?

I would guess all spin at idle... At least all turbos that we deal with will. Yes there is a turbo that will be so large and will have to much mass that it will not rotate. But i would be really surprised if anyone has installed a turbo that would not spin at 1000 rpm (unless its bearings were fuckkked)

I just went down to my newly rebuilt T25 sitting on my workbench and it spun when I blew through it. I think a Miata at idle puts out more exhaust gas than my breath, and probably smells better(HAH, beat y'all to it).
For info, the cold side of a turbo's turbine is called the compressor. There are three parts to a turbo's rotating assembly. The compressor wheel, the shaft, and the turbine wheel. Most turbos come with the turbine wheel attached, welded, sealed, whatever to the shaft. The compressor wheel is attached with a small nut.

yeah with my turbo off you could blow into the turbine inlet and make it spin. 1psi of compressed air from my air compressor could make it spin.
start the car with the intake off and youll see it move.
