Laptops typically shut down due to overheating (much heat, small area). There are several remedies for this. Since it was shutting down before you messed with the fan, the fan is probably not the problem, however, it could be overworked because of excessive heat elsewhere. You could go into the BIOS and see if there is a hardware monitoring feature that can be analyzed and adjusted accordingly. There is a possibility that the processor is going bad. You could disassemble the laptop and coat the internals with thermal cooling compound (available at most computer retail stores). You could purchase a laptop cooling pad. These come in many varieties with such things as extra fans and increased air flow space. The cheap simple solution would be to maximize the power-save features, turn off the laptop often to allow it to cool down, leave the AC adapter plugged in only long enough to fully charge the battery, raise the laptop off of a flat surface during use, ensure the few vents are clear and available for maximum airflow, and have a fan (any fan) blowing directly on the laptop in the vicinity of the processor while in use.
