Note: Loosen the screws [1], [2], [3] and [4], but do not remove them. When you attach the fan, secure the screws in order as shown in this figure.
Please perform the following step as shown in the picture below.

VGA thermal device/fan installation
For ThinkPad W700ds and W701ds:
When installing:
Before you attach the fan assembly to the computer, apply thermal grease, at an amount of 0.2 grams, on the part marked [b] as in the following figure. Either too much or too less application of grease can cause a thermal problem due to imperfect contact with a component. For the new VGA thermal device/fan, you need to peel the thin films off from the rubbers marked [a].
Make sure that the fan connector is attached firmly.
