Clean-up notebooks fan and fan refueling

I have a ThinkPad T43 , using the screen suddenly appeared "FAN error" prompt, and then automatically shut down, and repeatedly tried several are. Prompt the point of view, is the laptop cooling fan is a problem. From the external clean up the fan and radiator outlet of the dust, but the fault remains. Struck with bamboo fan leaves, and found that fan leaf rotation is not flexible, resistance, and the description of the fault really lies in the fan. We know that the books of the cooling system is mainly composed of heat sink, heat pipe and fan. Books fan rotation is not flexible, the speed decreases, the cooling capacity of the cooling components will drop, along with increase in CPU and GPU temperature, when the temperature rises to a certain extent, BIOS or CPU will be issued a warning prompt and automatically shut down, some The books will be a blue screen or crash.

From the outside can not be cleaned the fan had to open books, remove the cooling components, once again clean up the fan, but still did not improve, indicating that the problem is only open fan in the fan on the internal shaft to deal with. T43 fan is direct pressure on the heat sink, no screws to open the fan, you must pry open the four fixed points of the fan aluminum case.

The demolition must be careful not to damage the heat pipe and heat sink. Otherwise, the loss. The specific method is: use one word to head a small screwdriver, slowly into the gap between the four fixed points next to the heat sink and fan aluminum case in turn leveraging the fan and heat sink separation, and then gently pull out the fan leaves . If you can not pull it out, must not pull hard fan shaft sludge seal, required 99% alcohol soaked fans will be able to remove, usually after a dozen hours.
