This happened on a computer of a client of mine.
I was cleaning the computer and decided to remove the heatsink+CPU fan block from the motherboard. It is a very easy setup, with two levers on the fan that, when lifted, loosen the arms that are latched to 4 plastic thingies that are part of the dock that is connected to the mobo. After lifting the levers you can remove the arms and take out the heatsink and the fan that sits on top of it. I did everything correctly, but still, one of the plastic thingies broke when I was lifting the lever, so the entire dock needed to be replaced as a result (I guess the extreme heat generated by the poorly ventilated processor weakened the plastic, rendering it extremely fragile....). But I am not sure how it can be removed. It seems there is no way to remove it without ruining it completely (like, maybe, drilling through the heads of the four plastic pins that hold it tightly to the board).
It's an ASUS boars, model: P4S800D, SiS 964.
I'd be very grateful if anybody could give me some advice on the matter.
I have purchased a new dock to replace the old, damaged one, BTW.
