ML605 FPGA Heatsink

Jump to solution

The heatsink on the LX240t on this board is slightly too tall for me to fit this board into my computer. I found the following chart from Radian:

Based on the bill of materials for the ML605 I'm guessing the heatsink on the fpga is the FA35+K52B+T710. The question is as follows:

 

Would any of the shorter heatsinks, say, HS2132DBP3828K522 work? It's passive, so I'm worried...

If none of the Radian heatsinks work, can anyone suggest another source?

How hard is it to change the heat sink on the ML605? Can I do it without special tools?

 

Thanks!

You can pop off the heatsink on the ML605 by insert a small screwdriver in the slots in the plastic retainer.  You should be very gentle when you do this to ensure that you are just pushing out the side plastic tab and not leveraging the entire unit off the board solder balls and all.  Radian has an official tool to do this:

There is a thermal pad between the device and the heatsink so there will be some resistance to pulling the heatsink off.
