Recommendations for laptop cooling stands?

Laptop's overheating a bit, so I was thinking about getting one.
Looking at this cooling stand, but not sure how significant the difference between the 15'6 laptop and the 15'4 cooling stand will be.

So, any recommendations?

thats probably the one i know of, if u check the feedback of that 1 review
"Pros: It is sleek and simple, and quiet. I like that it has an extra usb port to make up for the one it takes

Cons: It's not comfortable in your lap

Other Thoughts: I think it was a good buy"

its the only 1 i reccomend
