My original fan was making a terrible noise from the bearing failing. It would also overheat after a couple of hours. I replaced the fan and heatsink and now my computer is quiet and cool again.

This fan and heatsink matched the one that was originally installed in my Lenovo T420S. It solved my "Fan Error" message, laptop overheating, and very slow computer issues. This unit has been installed for over 2 months and is working flawlessly. I was able to replace this fan/heatsink myself by reading information that is shown on the internet. I am very pleased with the results.
