Hello, we have bought the passive version of VCU1525 (the active version does not have enough cooling either) and want to replace the default heatsink with something more powerful. The mounting holes for heatsink on the board are 60.6 x 48.5 mm and the VU9P chip's heatspreader seems to be 27.2 x 35.9 mm. I was looking for CPU coolers as GPU ones would not fit the board due to DIMM slots.
Do you have any recommendations

You can refer to heatsink solution and thermal guideline in ug575 and xapp1301:
What do you concern here? Or what parameter do you need to know on mechanical design? What's the power/thermal margin in your application?

Thanks for the documents. The power on our mining application is up to 260 W. The question is if there is any cooler which can be mounted on the VCU1525 board as the stock heatsink is not enough. The mounting holes seem to be in non-standard positions, so it is hard to find for example some CPU coolers which would fit.
Or is the only solution custom heatsink design?
