HP w8000 manual Removing an Existing Processor, Heatsink Warm-Up Time

Hardware Upgrades

Heatsink Warm-Up Time

Minimal warm-up time is required to generate enough heat to soften the compound holding the heatsink to the cold processor.

CAUTION: Lifting the heatsink straight up while it is in a cold state can result in damage to the processor, because it may prematurely pull the heatsink and processor assembly out of the processor socket. If this should occur, you will need to open the processor socket, by lifting up on the processor retention lever, before attempting to install the new processor.

From a power-off state to a power-on state, see the following steps to warm (but not overheat) the heatsink so that the heatsink can be handled comfortably while the compound holding it to the processor is still pliable.

1.Turn on the workstation and allow the operating system to boot.

2.Shut down the operating system properly, then turn off the workstation and any external devices. Disconnect the power cord from the grounded AC outlet.
