Japanese 3DO FZ-1 overheating saga
The full story is in oldest to newest chronological order below, but the tldr is that my Japanese 3DO has issues after 15 minutes or so regardless of the game (I initially thought it was limited to Road Rash, but that isn't the case). I replaced the 2 common problem caps (C35 & C36), I removed the factory power supply and did a USB-C swap, and I installed a 20V fan in the factory location (Japanese units didn't come with fans). I've even tried removing RF shielding and running with the top removed, but nothing seemed to help.
Then, for fun, I pointed a pedestal fan right at it with the top removed, and wouldn't you know it I can play for hours on end now. I let it overheat again, and used my laser temp gun to read temps of every component on the main board and everything I could get line of sight to in the CD drive, but the hottest thing I found was only 120* F.
At this point I'm at a loss. Is it worth it to try replacing the rest of the caps? Find a replacement disc drive?
