Few hours after plugging in my DDC to channel 1, which is set to adjust the pump's power between 50% and 100%, I smelt something burnt coming from the Aquaero (my case was still open from installation), then after uninstalling it from my pc and took off the heatsink, this is what I found;









There seems to be brown marks around the FET and some sort of solder-like substance coming out between the FET and the PCB...

Also in the picture the 2 resistors increasing channel 1 power are clealy visible, so there is no doubt wether this is the factory-modified power-boosted version (which is a little brownish itself).

Any thoughts? It heats up as it reduces the power going to the pump, then overheats itself... I thought it was modified so that it can handle the DDC's load?
