Antec Notebook Cooler for 6400/E1505

Hey guys, I've been looking at the Antec Notebook Cooler for my 6400 (i'm in Canada). First off, my laptop, goes to 55 degrees celsius when multi-tasking (playing games, music, downloading, 3d graphics modelling since i'm an urban planner).. not good. So I decided to improvise, put a piece of staedtler eraser at the back to lift it up a lil, and place a fan blowing at the back at 3rd speed. It brings the temperature down to a stable 35 degrees celsius. Woohoo! BUT, It's.. not very convenient.. have to bring that big fan wherever I go..haha.

Anyway, I was about to go to Canada Computers to buy an Antec notebook cooling pad. But, here's the deal, there are 2 different Antec Coolers with 2 descriptions.

1. Antec Notebook Cooler 2X70mm DBB FAN Aluminum surface with USB-Powerd

2. Antec Notebook Cooler 80X15mm 25.9dB

Okay, I did abit of research and stuff, the difference is in the fan size and a $1.01 difference. So, which size fans are the one I should get? Does the 80x15mm notebook cooler have an aluminum surface? It doesn't mention. I don't want to look like an idiot going into the store and buying the wrong one.. so.. what's the difference between those 2 really? And which one should I get?

Thanks

 

Any answer?? I want to know too!!
