Seeking smaller heat sink alternatives for Jetson Thor

Robotics & Edge Computing Jetson Systems Jetson Thor

I was curious if anyone has done any heat sink modification on the Jetson Thor yet. I intent to use Thor in a robotics application as a replacement for the prior gen AGX Orin 64gb. The AGX Orin used was more or less a developer kit with the following heatsink:

70861-HS
Auvidea Heat Sinks
US HTS:8473305100 ECCN:EAR99 COO:CN w/ a larger fan.

Can be seen here:

Obviously, out of the box the Thor is double the size due to the heatsink size increase. My Thor is scheduled to arrive this week so I am unable to measure. I am curious if anyone can confirm whether the mounting holes are in the same location between these 2 models. I understand Thor will require additional cooling but would seek to achieve this through a fan mounted on top rather than the additional space to the side of the carrier board. Size constraints are an issue side to side but not top to bottom.

I did see a few solutions available. I like this one: Access to this page has been denied.

but am not sure of anywhere that includes the fan and allows orders of 1 without a significant lead time. Located in the US.

Please refer to section 7.3.1 and Figure 7-2 in Jetson AGX Orin Series Data Sheet (Including AGX Orin Industrial) and section 6.4 and Figure 6-2 of Jetson Thor Series Modules Data Sheet.

The X and Y dimensions and the screw hole mounting locations are the same for both modules but The Thor module is slighly shorter.

The Jetson Thor Series Thermal Design Guide (as well as the Jetson AGX Orin Series (including AGX Orin Industrial) Thermal Design Guide) also has the X and Y information in addition to other requirements and recommendations for the cooling solution, like locations where thermocouples should be placed on the thermal transfer plate (TTP).
