    I fried my temperature sensor and now it artificially overheats

    I have a Gateway M-1625 which I just took apart to reapply thermal paste to the CPU. The laptop has a bar connecting the CPU to the fan heatsink. This bar also contacts a pair of little cubes, but the buffer was not a paste; it was a thin paste/foam strip. I (falsely) assumed this strip was thermally conductive, so I replaced it with fresh thermal paste. I started the laptop up, let it begin to boot, and the fan started running at max speed. The computer shut down quickly. I've been using CPUCool which comes with a taskbar temperature sensor display. When I started the laptop again, one of the temperature sensor displays was gone. Before I fried it, the sensor changed slowly compared to the ram sensors and the fourth sensor, but it stayed fairly high most of the time. So it seems like that pair of cubes were a temperature sensor, and I'm guessing I drove that temperature sensor through the ceiling when I connected them to the CPU heatsink bar. This is my best guess, comment if you have another guess.

    How do I tell my laptop to ignore this temperature sensor and not falsely overheat? It's a junk laptop, so I'm not getting professional help, and makeshift solutions are okay. I'm about to pull out a soldering iron and rip the little cubes out. Is this a good idea? If not, does anyone have a better idea?

    The bar is the heat pipe. As far as the cubes they may have been internal ambient heat sensors. Removing one may stop the system from booting, then again it may do nothing. This is more determined from the bios and what it needs to see to post. I couldn't advice one way or another on that.

    My advice would be to go to an electronics parts store to see if you can get replacements or even order them from online..............
