Heatsink for Jetson TX2 4GB SOM

Hi,
We are using Jetson TX2 4gb SOM for our project, and we are not able find any active heatsink for the SOM as the heatsink holes for the 8gb SOM dont match with the 4GB SOM. we searched online and we found connecttech XHG304 heatsink but the price of the heat sink is very high.
Can you please recommened any heatsink that Nvidia uses for the 4GB SOM?

Thanks,

Hi,
The suggested heatsink for the 4GB TX2 SOM and TX2i SOM is coolermaster DCV-0917-N1-GP in the supported component list. but there does not seem to be any stock available anywhere, can you please recommend any vendor or the datasheet of the heatsink where it is available.

Thanks,
