Recommended Cooler for Inspiron 1720

So I bought me a Dell Inspiron 1720 (Specs are: Intel C2D T7300, 160GB 5400RPM HDD 17" Widescreen, 2GB DDR2 667, GeForce 8600M GT) for Christmas and I was looking around for a cooler, something like this Zalman cooler I found.

However, that specific cooler is for a 15" laptop and mine is a 17", I would prefer a cooler that is made for a 17" Widescreen laptop so it would cool better and not be hanging over the coolers edge.

Normally I wouldn't even bother with the cooling besides the fans that its got but I want the notebook to last quite a while and I could just pack the cooler in the backpack I plan on packing my notebook around in.

Peace
