The processor’s cooling system includes a heat pipe and a fan. The speed of the fan is varied depending on the CPU temperature. To tell you the truth, this fan is idle most of the time – it’s when SpeedStep technology steps the CPU frequency down to 800MHz and the CPU’s heat dissipation goes down to 9 watts only.

You should meet no problems installing memory. There’s a special cover at the bottom of the case that conceals the SO-DIMM DDR2 SDRAM slots and the graphics card.

Note that being based on the i915PM chipset, this mobile computer supports dual-channel DDR2-533 SDRAM. So you may want to put two identical modules into the available memory slots to achieve the highest possible memory performance.
