I need a cooling pad for my laptop, but I need help deciding which is better: 2 big fans, or 6 little fans?

Laptop specs (14 x 8.9 x 0.7 inches)
- Dual Core i7 Kabylake
- GTX 940mx
- 15.6" 4K display
- 16 GB RAM
- 512 GB SSD
- All aluminum build
- Battery is located near the bottom (mostly the reason I am concerned with heat, I want it to survive while gaming)

2 big fans
- 150mm (6in)
- 1100rpm

6 little fans
- 70mm (2.7in)
- 1800rpm

If you need more info, you can ask. If you have any recriminations for cooling pads, please let me know (under $20). (Perfered dimensions: about 14 x 9 inches)
Thanks!

2 big fans if you like a quieter running PC :) I don't know the performance difference between these two but I can tell you the normal comparison between 80mm fan and a 120mm fan is HUGE: 2x the airflow with the 120 vs. the 80. That's why you see so few, if any 80mm fans in aftermarket micro/mid/full size ATX cases, and explains the trend to even larger fans that turn slower, are quieter, and move much more air.

Look at CFM (the measurement of air flow) and decibels between what you're deciding and let us know what you find
