174MM-C fan vibration

I have lot of fan vibration. For some reason it seems to resonate in my autoguide setup and I can feel it more in my Guide camera and main camera filterwheel, than in the ASI camera itself.

Honestly I don't yet know if this is causing an issue for me or not but it is surprising to feel the guide camera (on an external scope) vibrating whenever the ASI fan is on.

ASI and filterwheel are on an 8" SCT. Guide scope is an orion short tube 80, mounted via scope rings attached to scope rings on the SCT.

Thoughts?

I will try to determine if this is affecting imaging or guiding.

the fan is turn off if you stop cooling

so you can test it in this way

Turning the cooler off in SGP doesn't seem to turn the fan off, so I can't really test, unless it's OK to run it (un cooled) without the 12v power connected (USB power only)?

yes, you can try it without the 12V power supply

old version of cooled camera cannot control the fan
