the wire connecting the fan to the motherboard was easy to pop out With needle nose pliars without doing damage. it didn't produce any error message. Now i can enjoy blissful silence. I expect my basic Romeo to run cooler even though the fan is off, because im keeping the lid off of it. when the lid was on, the top lid was always hot to the touch. In system settings i see MBT. I assume stands for motherboard temperature. mine reads 34. I also removed the wifi lan module board from the TiVo. it popped right out after removing a screw. I confirmed I was able to reattach the board and wifi function resumed. I'm keeping the wifi bored off just because I'm paranoid of any unnecessary WiFi signals.
