hp laptops have no heating issues, it was the problem of old models that were use to come, now they developed a technology called coolsense through which the temperature remain under control. I don't use any coolpad.
That's due to cooling improved in Intel processors in 2nd gen as the root cause were first gen CPUs. Also, coolsense is a power management program which under-powers the components when temp crosses specific threshold, thus temps are in control.

scroll down and you can see the Samsung NP550P5C-S02IN price is TRUE
The GPU in its spec is 650MX. Still very good.
