47 Installing the heatsink and fan assembly Caution! The heatsink fan assembly has a thermal interface material (TIM) on the underside. Use caution so that you do not damage the TIM. If a protective film is installed on the TIM, remove it. 1 Perform the pre-installation instructions described on page 26. 2 Remove the side panel described on page 28. 3 Lay the server on its side (components showing). 4 Do not apply any thermal grease to the heatsink or the processor die; the required amount has already been applied. 5 Place the heatsink on top of the processor (1) so that the four mounting holes are aligned with those on the (preinstalled) heatsink retention mechanism. 6 Use a screwdriver to tighten the four heatsink screws (2). Do not fully tighten the screws or you may damage the CPU. 7 Connect the heatsink fan cable (3) to its connector on the mainboard. 8 Observe the post-installation instructions described on page 27.
