Does the XGS1250-12 have/use active cooling?

i've had to RMA two XGS1250-12 units and currently on my thrid, the previous ones just cooked themselves to the point where the 10G Ethernet ports just stopped working, there seems to be a serious design flaw on these, i've had to put an 80mm 5v fan at one end to blow air across the until just to keep it cool.

I just ordered one and I had not seen this thread. I am planning to use all 3 of the 10Gbe ports. Should I be preempting the cooling? I don't have any copper plates but I do have a lot of pennies and thermal pads. So theoretically I could strategically place the pennies above any hotspots on the existing plate to transfer some heat to the case.
