Hello
I have a problem with the fan QHY8.
The telescope tube (Newton D350mm F1500) resonates with the fan of the CCD and the stars come out blurred.
I've thought about changing the fan for another with less rpm, less db and equal m3 / h but not know the technical data that is installed, which is:
NIDEC BETA SL
Model D98R-12TL09B
12V 0.08A
Would you know the rpm data, db and m3 / h of this fan? to see if I can place him one better.
Thanks

Its not a critical item, so just use a computer case type fan.
Just make sure its the same height.
But you can also place a 1 watt wire resistor or 100 ohm pot (Variable wire wound resistor) and place in line with Fan wires (Found on back of fan).
Make sure you verify it is the fan causing issues, because there isnt much vibration from one of these fans.

Thanks Theo for your answer
The fan had broken one of the plastic feet that support the central rotor and barely visible.

Thats good that you found the problem. You should be able to get one from your local computer shop. Just gring down your fan to compare it to.
You may get one that has a tacho wire on it (3 wire fan), and its fine to use. Just dont use the tacho wire (Normally yellow wire).
