Papst is known good brand. I have seen another brand fail miserably so 
this is why I am asking.

Yes, and the EBM-Papst 624 matches it well. The Papst seems to have much 
lower noise from the datasheet.

BTW. Both my SR620 checks out well. One of them was supposedly diagnosed 
with flicker.

I still need to do the sensitivity part of the measurements, but lacking 
a suitable RF generator I can't do it smoothly.

The fan in the new TIC locks itself into one position, so I had to help 
it. I don't know if it is worth the trouble to open it up, clean and 
lubricate.

Cheers,
Magnus
