Perform the following steps once you have installed the new processors and ready to re-install the heatsinks.

Preparing a New Heatsink for Re-installation. If you have a existing heatsink, follow the EXISTING Heatsink procedure.

Apply the top gasket included in the parts box to the top of the heatsink.

If you are replacing the lower processor heatsink with a new heatsink, install the bumper included in the parts box on the side of the heatsink.

Do not apply thermal grease to a new heatsink. It comes with thermal grease already in place, covered by a cap over the bottom of the heatsink. Before installation, remove the cap.
