It is the Lenovo Fan Speed Control Driver. Current file name ID1FSC01WW6.exe is for Windows 7 (64-bit) I have an SL300 with a fan always working on Windows 8 x64 Pro. This driver installed just fine and is reported as working under device management. But I see no performance improvement or manual controls over my laptop's fan speed.
