No display and seemingly power cycling over and over

A while ago I opened up my brand new (never powered on) 2018 Mac Mini, and following the guide here I swapped the base RAM for the OWC 64GB upgrade.  After putting everything back together, I hooked up the Mini to my Apple Thunderbolt displays.

When I hit the power button, the front LED lights up but there’s no image on the Thunderbolt displays.  Furthermore, after about 30-40 seconds the LED turns off and the fan makes a brief “woosh” sort of sound.  The LED stays off for roughly 10-12 seconds then turns back on, repeating the cycle over and over.

Does this mean I don’t have the RAM installed properly, or maybe it’s the wrong RAM?  Could it be a power or fan issue.

I double checked the Thunderbolt displays and they work fine with my Macbook.  I’ve tried using a standard TB cable into my USB-C adapter as well as the regular TB line from the back of the TB display, but it changes nothing.  I’m lost.
