I've been following this thread. Very interesting points you guys are discovering. Jhautz also showed in detail about the possible fan plug issue.

I opened mine back up to check out the heat sink you guys have been discussing. I felt it was worth pictures. Here they are:

In this first picture, please notice that my motor power cups have ample spacing.


In this picture, my power lead cups are touching the heat sink. Bent heat sink pins as previously mentioned.


This last picture shows the lower case mod that I did to create clearance for the fan plug. IMO, it's not necessary to go completely through the plate.


Please Note: In the upper right hand corner of this last picture, I found a resistor riding right on the support rail. I also removed material to clearance for that.

What can I do about the power lead cups touching the heat sink? I don't have a good feeling about this. Those pins will flex/rub under shock and vibration I'm sure. IMO, this should have additional clearance to prevent problems.

Replace the connector with wire leads...

thus voiding the warranty. ill just leave it be, and if it fails -its castles fault!!! but with them touching (look down the bottom, its almost glued to the heatsink...?)

u could always just cut the fin/s off?
