My best suggestion is to rethink what you want to do.
Laptops are for portability.
If you MUST have portability, then you must settle for a laptop and lessened gaming performance.
Laptop coolers are inefficient because they need to be small and light weight.
When gaming plugged in for best performance, thermal throttling is very likely.
Usually, you can get a better processor, cpu, and monitor for the same price.
