I apologize for so many questions, but I’m trying to build a case for purchasing one of these to my management. Do you have a picture of what the SM200A looks like with the active cooling option? Does the heat sink get replaced with fans or fans added on top of the head sink? Also, how do the fans get their power? I’m assuming there’s a port or connector somewhere on top of the case. Is the fan assembly user replaceable in case it fails? Do you have any measurements of the audible noise generated by the fans? Thanks again for answering my questions!

Here is a picture. There is a connector that comes up through the case to power the fans. There are 6 fans, each 23 dB(A). I believe it can be replaced by the user, since you do not have to open the main enclosure to replace them. The fans are kept off until the FPGA reaches a certain temperature (I believe 50C), and then they turn on (until the FPGA is below 30C), and I believe the fans turn off for phase noise measurements.
Let me know if you have more questions.
