I am wondering if anyone has installed a smaller muffin fan on or near there IC heat sink? I just replaced the IC on my Mitsubishi WS-55711 and it seems to me that the heat sink is really hot. I used an infrared thermometer to check it and it reads about 125 deg. Is this normal or should I be nervous. I made sure the chip was covered with heat sink compound before I secured everything down. Any tips or thoughts would be appreciated.
Thanks
Can't tell you what is a good temp, but I had a chip running at 140F. Took a bottle cap, and cut it into a flower using tinsnips. Bent the 'petals' down and cut off every other one for room. Used heatsink compound to hold it in place on the chip in my AP. Temp went to 113F and is holding.
*I* think it was running hot, and would have failed. But I am not an engineer.

Does anyone know where I can pull 120v off PCB for this fan idea on a Mitsubishi WS-55711?
Thanks
