The parameters that define how much a heat a cooler can dissipate are the ambient room temperatures, amount of surface area on heatsink, the metals used, the type of contact of these metals, and the ability to move air through that cooler to dissipate the heat. There is a reason two coolers with the same surface area and different amount of heatpipes can perform different than each other.
Also, those numbers you pulled can easily be thrown away by searching for proper reviews done on the internet by credited and reputable people such as

For instance, this is a stock Hyper 212 Evo keeping a Habanero under 90C while dissipating ~180W through the chip.

I have some Habaneros pushing 600W into the chip running a single H80i with a 240CFM fan.
