Porsche 930 noise from air vent

[Tomy]

So I drive second time with my black on black 930 what a drive... ! one small problem appear : I have noise from 2 places :
-first from very small electric engine just under trash - it is connected to hole under VDO instruments - looks like it is kind of sensor for temperature control ? this small 3 inch electric engine make strange noise I disconnect it temporary. It could be rebuild or need to by new. By the way what it is exactly ?( temperature sensor feedback?)
-second noise from left side down vent ( going from vent) I am not similar to this age of Porsche cars so I am suprise : it means that they are extra 2 air blowers both side left and right ( and of course we have blower in the middle like in old construction?) it is to repair or need to buy new ? any experience with such problem?

I have this same noise on my 930 what appears to be behind the radio on the left.

OK first noise source solved - it was temperature sensor electric sensor - I take it out open -find some moving small part (taken out) clean, lube and assembly - now erratic noise now.
Next problem still to be fix - I would need to remove blower disassembly and probably wold have same problem like above.
