According to what you said the phenomenon may be caused by the following reasons:
# fan installation is not strong or loose, you can check the fixed fan of steel, to see if less flexibility not achieve fixation, if so, remove it to replace one.
# If the fan shaft is not correct, then the process in the rotation because of large swings, with the fan box collision will lead to this phenomenon. In such cases, it is best to replace a fan.

You can not just replace the CPU fan for heat sinks, fans are generally fixed with screws on the heatsink, as long as the screw removed, you can remove the fan, and then replace a same diameter of the fan, pay attention to the installation of must be right now, otherwise it will affect the cooling effect.

You can open the laptop when it presses the middle fan to stop and see the sound is not nothing, if no explanation is CPU, if there is a power supply fan. There is sure to buy a new fan try, first, listen to the voice, the second is to look at vibration. Vibration as small as possible. Proposed two-ball fan to buy a cooler.
