My E14 Gen 4 looks somewhat different. It is an AMD-Model. The fan has no screws—neither for securing the fan itself nor for removing the metal plate, which is riveted or something like that. The heatpipe has an extension to cover some voltage regulators right of the cpu. I was told not to apply thermal paste there.
Here are some images of my fan. Feel free to use the aimages for this howto:⏎
