Fan fixation

Hello, we bought Jetson Nano and found 4 holes on the top surface of radiator. So I have a question: “How mount a fan to the radiator?”. There are no thread’s in holes and I’m in dismay how we can connect those components. My first idea was use a nut and long screw, but actually it’s not a such good idea

Hi, please check thermal DG for that:

Thank you, but in this guide has no needed information. Please look at the attached photo. Out of box Jetson Nano has a heat sink and I have no clue how mount at this heat sink the fan.

The guide is for custom design and for module not for dev kit with heat sink. Dev kit is a full design, we have no guide for a fan on heat sink. Customer should handle that by self.
