I have an ASUS N56VB and have been researching laptop coolers for a while now (or maybe even too much). I checked the areas where the laptop overheats when playing games and noticed that it happens only on the left side. Even the hard drive, which is on the bottom right, is unaffected. Also, I think the vents are not at the bottom of the laptop but on it's left side. There are of course a lot of brands which make the choice even harder.
Considering those circumstances, I am not sure whether to buy a cooling pad with 1 fan, 2 or 4 fans. 1 fan lies always in the center, and the heating occurs on the left side only. 2 fans might be sufficient. 4 fans, while at the right areas, seem redundant.
Here are some pictures:
I thought that maybe this will be good: http://www.amazon.com/BlueFinger%C2%AE-Arrival-Notebook-2200-4000%C2%B110%25RPM-Ultra-portable/dp/B0148IKWYS/ref=sr_1_1?ie=UTF8&qid=1455965509&sr=8-1&keywords=Bluefinger+2+in+1 As it has both a cooling pad and a cooler on the side, but there are not enough reviews for this product.
Another good product is this: http://www.amazon.com/Cooling-TeckNet-Notebook-Adjustable-Temperature/dp/B016CL2F5S/ref=sr_1_1?ie=UTF8&qid=1455965555&sr=8-1&keywords=TeckNet%C2%AE+Gaming+Laptop Mainly because of the temperature display and the on/off switch (which hopefully also turns off the fans themselves).
Or perhaps this one (or something similar? there could be others that are way better): http://www.amazon.com/Thermaltake-Massive23-Notebook-Oversized-CLN0015/dp/B003ZUXXWO/ref=sr_1_1?ie=UTF8&qid=1455965583&sr=8-1&keywords=Thermaltake+Massive23 Perhaps one fan is better? I'm not sure.
So far I'm thinking about the BlueFinger cooler (mainly because it is pad&side cooler) but the lack of reviews is disturbing. I would really appreciate your assistance as I have never bought a laptop cooler before.
