Pass Labs cooling noise


 I have a recently purchased Pass Labs INT-60 that is making periodic clanking noise as it is cooling down on turn off.

My many previous non- Pass amps were always quite, Mac’s and  even my Parasound JC5.

Any ideas before reaching out to the dealer/company?

BTW the Pioneer S-1ex’s sound amazing with this setup with the OS Audio Directstream and Oppo 205.

X350 does the same think. I assume it's because the heatsinks are structurally part of the chassis and cool at a different rate.
