Which laptop cooling pad would be best?

[Fleur-De-Lis 350]

So I have a Dell Inspiron 15, 5000 series (the 5555). It was a present I got a while back (Super helpful for college! its mostly going to be a work computer.) However for certain reasons (such as how my favorite game series Hyperdimension Neptunia does not work properly on my desktop and locks up; but works perfectly fine on my laptop) I plan on doing light gaming on it, however over the span of half an hour to just over an hour the laptop starts getting pretty hot (not much though), at its hottest so far at almost an hour and a half it gets comparable to the heat a PS4 outputs! Which is pretty dang hot. There have been no overheating issues thus far, but I would still like to keep it a nice cozy and cool temperature.

 

So with that I had decided that I should invest into a laptop cooling pad, one with a fan and such. However, here is where things start getting a bit complicated. The reason I specifically mentioned the model of my laptop is so people can familiarize themselves a bit with its hardware layout to best determine which laptop cooling pad would be best suited for the job.

 

A majority of the heat is from the upper and middle left, and on the lower right.The best images of its underside I could find was here http://laptopmedia.com/highlights/dell-inspiron-5558-15-5000-first-impressions-mid-range-multimedia-laptop/ just use the pictures as reference. (as only the layout is in common, mine is an AMD version)

 

Since this is my first laptop, and more specifically, the first time I am buying a cooling pad for a laptop, I want some opinions on what to get since there are apparently so many different kinds of laptop cooling pads.

 

note: all links below are from amazon.

Here are two prime examples Cooler Master notepal x-slim, I am not sure what the big difference is between that the X2 and the X3. Then there are things like the tecknet last notable one I can think of us these strange 4 fan ones such as EGOGO laptop cooler

 

So with all that story and examples out there ... anyone care to offer suggestions and feedback on which would be best? please keep the price range $30 or less, however if you really believe its a particularly good and high quality cooling pad then I guess i'll up to to $35

 

I am hoping for a life span of at least a year. keep the searches limited to amazon or newegg, thanks.

 

Lastly. I would like to say I am personally leaning towards the cooler master notepal x-slim.
