Your post regarding an air cooler dissipating 350watt is nonsense. Dual 120mm radiators with decent fans of 1500-1800rpm would dissipate up to 300w. I am not sure where you're pulling your magical unicorn numbers from. Feel free to post a air cooler that can dissipate 350watts, make sure it doesn't have 5000rpm fans attached to it.
I just need to quote this to show you don't know what you're talking about and you're not worth arguing with.
