How much cooling is needed for XPS 16?

Ok, here I am once again. I have ordered Dell S XPS16 with the below configuration:

Intel Core 2 Duo T9550(2.66GHz/1066Mhz FSB/6M L2 Cache)
Obsidian Black High Gloss Finish with Leather XPS 1640
4GB, DDR3, 1067 MHz 2 Dimm
16.0 inch Wide Screen 16:9 1080p FullHD RGBLED LCD W/2.0 MP
ATI Mobility RADEON M96XT (this is HD 4670 right??) - 1GB
500GB 7200RPM Free Fall SensorSeagate Hard Drive
Microsoft Windows Vista SP1 Ultimate 64-bit
BluRay Combo Drive
Intel WiFi Link 5300 802.11AGN Half Mini Card
56 WHr 6-cell (Will order 9 cell battery later with the 100$ gift card )
Dell Wireless 370 Bluetooth Internal (2.0+Enhanced Data Rate)

I plan to use the laptop mainly for Internet browsing, watching blu ray movies, some gaming. I do not plan to do any hard core gaming (some strategy and racing games like AOE, Ceaser, NFS etc.).

Please let me know what all from the below do I need to do for the heat problem (if any):
1. Undervolting CPU
2. Get Cooling Pad (I currently have Antec, but if needed I can buy Zalman NC2000)
3. Replace thermal compound

Thanks.

 

Under normal usage, it's actually just under the touchpad that gets the hottest. Some bright spark at dell thought it would be a great idea to use the chasis as a heatsink for the southbridge rather than give it a heat pipe of it's own.

 

I suggest you wait until you get the pc and install speedfan or some other program to monitor your temps to see if you even have a heat problem - you may not need any of those w/ the apps you'll be running......

 

I always recommend undervolting no matter what since it saves on battery time, reduces heat and extends the life of the components. As for the cooling pad, I've read good things about the Zalman (which I plan to get). Thermal compound replacement is only something I'd recommend as long as you are comfortable opening up the entire system.
