I went to Sony's support site (using the model number from the sticker under the laptop: ). I looked for "Driver - Firmware" and downloaded a file called Sony Firmware Extension Parser Driver (sometimes labeled "Sony Shared Library" or "VAIO Control Center").

"ACPI? That's power management stuff. SNY? That's Sony. 5001? No idea," I thought.

I installed it. It took 10 seconds. No reboot needed.

That's when it clicked. The fan wasn't broken. Windows simply didn't know how to control it because the driver was missing. The laptop was running a "safe mode" fan profile: ON all the time.
