I'm going to FrankenMac my old LCII with a dead PSU with a working one from a donor LC. Back 20 years ago the LCII kicked the bucket because the Speedster 040 card I had installed caused overheat issues. Fast forward today and I'm looking at adding some kind of extra cooling to the LCII to ensure it doesn't kill itself again. I have the small square hole open on the back and am thinking of squeezing a small fan in there to pull heat out. Alternatively I was thinking about my Mac Pro where it pulls air in the front and pushes it out the back. Because the LC series is slightly elevated, does it seem like a good idea to reverse the bottom fan to suck air in and have it come back out the rear? Another idea I had was entirely replacing the old fan and installing a newer faster/efficient one and possibly re-areanging the speaker to be another fan. Any opinions or ideas?
